Data from this early period shows that government funds to finance the expansion of education came from a number of different sources, but specifically taxes at the local level played a crucial role. The historical role of local funding for public schools is important to help us understand changes &#x2013; or persistence&#x2013; in regional inequalities.</p><p>The second half of the 20th century marked the beginning of education expansion as a global phenomenon. Available data shows that by 1990 government spending on education as a share of national income in many developing countries was already close to the average observed in developed countries.<a id="ref-2" class="ref" href="#note-2"><sup>2</sup></a> This global education expansion in the 20th century resulted in a historical reduction in education inequality across the globe: in the period 1960-2010 education inequality went down every year, for all age groups and in all world regions. Recent estimates of education inequality across age groups suggest that further reductions in schooling inequality are still to be expected within developing countries.<a id="ref-3" class="ref" href="#note-3"><sup>3</sup></a></p><p>Recent cross-country data from UNESCO tells us that the world is expanding government funding for education today, and these additional public funds for education are not necessarily at the expense of other government sectors. Yet behind these broad global trends there is substantial cross-country &#x2013;&#xA0;and cross-regional &#x2013; heterogeneity. In high-income countries, for instance, households shoulder a larger share of education expenditures at higher education levels than at lower levels &#x2013; but in low-income countries this is not the case. Malawi is a stark example: tertiary education is almost completely subsidised by the state, yet household contribute almost 20% of the costs of primary education.</p><p>Following the agreement of the Millennium Development Goals, the first decade of the 21st century saw an important increase in international financial flows under the umbrella of development assistance. Recent estimates show that development assistance for education has stopped growing since 2010, with notable aggregate reductions on flows going to primary education. These changes in the priorization of development assistance for education across levels and regions, can have potentially large distributional effects, particularly within low income countries that depend substantially on this source of funding for basic education.<a id="ref-4" class="ref" href="#note-4"><sup>4</sup></a></p><p>When analysing correlates, determinants and consequences of education consumption, the macro data indicates that national expenditure on education does not explain well cross-country differences in learning outcomes. This is indicative of a complex &apos;education production function&apos; whereby for any given level of expenditure, output achieved depends crucially on the input mix.</p><p>Available evidence specifically on the importance of school inputs to produce education, suggests that learning outcomes may be more sensitive to improvements in the quality of teachers, than to improvements in class sizes. Regarding household inputs, the recent experimental evidence suggests that interventions that increase the benefits of attending school (e.g. conditional cash transfers) are particularly likely to increase student time in school; and that those that incentivise academic effort (e.g. scholarships) are likely to improve learning outcomes.</p><p>Policy experiments have also shown that pre-school investment in demand-side inputs leads to large positive impacts on education &#x2013; and other important outcomes later in life. The environment that children are exposed to early in life, plays a crucial role in shaping their abilities, behavior and talents.</p></section>

This is a recent social achievement. The advancement of the idea to provide education for more and more children only began in the mid 19th century, when most of today&#x2019;s industrialized countries started expanding primary education. The following visualization, plotting public expenditure on education as a share of <a href="https://ourworldindata.org/gdp-data/">Gross Domestic Product </a>(GDP) for a number of early-industrialized countries, shows that this expansion took place mainly through public funding.<a id="ref-5" class="ref" href="#note-5"><sup>5</sup></a> Our entry on <a href="https://ourworldindata.org/primary-education-and-schools/">Primary Education and Schools</a> provides details regarding how this expansion in funding materialized in better education outcomes for these countries.</p><figure data-grapher-src="https://ourworldindata.org/grapher/public-education-expenditure-as-share-of-gdp" class="grapherPreview"><a href="https://ourworldindata.org/grapher/public-education-expenditure-as-share-of-gdp" target="_blank"><div><img src="/exports/public-education-expenditure-as-share-of-gdp_v1_850x600.svg"></div></a></figure><h4 id="how-did-the-us-finance-the-expansion-of-public-education"><a class="deep-link" href="#how-did-the-us-finance-the-expansion-of-public-education"></a>How did the US finance the expansion of public education?</h4><p>Public schools in the US currently educate more than 90% of all children enrolled in elementary and secondary schools.<a id="ref-6" class="ref" href="#note-6"><sup>6</sup></a> This is the result of a process of education expansion that relied heavily on public funding, particularly from local governments. The visualization below shows the sources of revenues for public schools in the US over the last 120 years. As it can be seen, states and localities are &#x2013; and have always been &#x2013; the main sources of funding for public primary education in the US. In fact, we observe three broad periods in this graph: there is first a period of stable revenues until 1920, then a period of sharp growth and decline during the interwar years, and then a period of substantial growth since the second world war, slowing down in the 1970s. In all these periods, federal funding was always very small, as can be seen when changing the visualisation from &apos;absolute&apos; to &apos;relative&apos;. Disaggregated data from the last couple of decades gives further insights into the specific sources of local revenues for schools in the US: the largest part comes from property taxes (about 80% of local revenues came from property taxes in 2013), while only a very small part comes from fees and donations (private funding for public schools, which is considered a local revenue, amounted to less than 2% of total public school revenues in 2013). This heavily decentralised system relying on property taxes has the potential of creating large inequalities in education, since public schools in affluent urban areas are able to raise more funding from local revenues. Indeed, a significant part of the debate on education inequalities in the US today focuses on the importance of increasing progressive federal spending to reduce inequalities in public school funding.<a id="ref-7" class="ref" href="#note-7"><sup>7</sup></a></p><figure data-grapher-src="https://ourworldindata.org/grapher/revenues-for-public-schools-by-source-us" class="grapherPreview"><a href="https://ourworldindata.org/grapher/revenues-for-public-schools-by-source-us" target="_blank"><div><img src="/exports/revenues-for-public-schools-by-source-us_v1_850x600.svg"></div></a></figure><h4 id="how-did-france-finance-the-expansion-of-public-education"><a class="deep-link" href="#how-did-france-finance-the-expansion-of-public-education"></a>How did France finance the expansion of public education?</h4><p>The case of the US above shows that funding for public schools has been historically a responsibility of local governments. In other countries, such as France, the expansion of public education also took place initially with resources from local governments, but relatively quickly the fiscal burden was shifted to the national level. In France this transition was associated with a sharp jump towards universal access and a concomitant reduction in regional inequalities. The following visualization from Lindert (2004)<a id="ref-8" class="ref" href="#note-8"><sup>8</sup></a> provides evidence of the French experience. As we can see there are three distinct periods: education spending was initially low and mainly private, then in 1833 funding began growing with local resources after the introduction of a law liberating communes to raise more local taxes for schools, and finally in 1881 the national government took over most of the financial responsibility after the introduction of a new law that abolished all fees and tuition charges in public elementary schools. In the source book, Lindert (2004) provides further evidence of how this transition towards centrally funded public education reduced north-south inequalities in France.</p><h6>Sources of funds for France&#x2019;s public primary schools, 1820&#x2013;1913 &#x2013;&#xA0;Figure 5.5 in Lindert (2004)<a id="ref-9" class="ref" href="#note-9"><sup>9</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown.png" target="_blank"><img class="aligncenter size-large wp-image-8026" src="https://ourworldindata.org/wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-672x550.png" alt="Lindert (2004) France_EarlyEducation_Breakdown" width="672" height="550" srcset="/wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-32x32.png 32w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-64x64.png 64w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-96x96.png 96w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-128x128.png 128w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-150x123.png 150w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-400x328.png 400w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-672x550.png 672w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown-768x629.png 768w, /wp-content/uploads/2016/06/Lindert-2004-France_EarlyEducation_Breakdown.png 1546w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h4 id="in-the-us-growth-in-education-expenditure-was-characterized-by-growth-specifically-in-the-public-sector"><a class="deep-link" href="#in-the-us-growth-in-education-expenditure-was-characterized-by-growth-specifically-in-the-public-sector"></a>In the US growth in education expenditure was characterized by growth specifically in the public sector</h4><p>A comparison of expenditure between public and private education institutions is helpful to contextualize the role that the public sector played in the process of education expansion in industrialized countries. The following graph does this using data from the National Center for Education Statistics in the US. It shows that during the years 1950-1970 &#x2013; a period of substantial growth in education expenditure in the US &#x2013; expenditure grew <em>specifically</em> in the public sector.<a id="ref-10" class="ref" href="#note-10"><sup>10</sup></a></p><figure data-grapher-src="https://ourworldindata.org/grapher/us-education-expenditure-as-share-of-gdp-public-and-private" class="grapherPreview"><a href="https://ourworldindata.org/grapher/us-education-expenditure-as-share-of-gdp-public-and-private" target="_blank"><div><img src="/exports/us-education-expenditure-as-share-of-gdp-public-and-private_v1_850x600.svg"></div></a></figure><h4 id="when-did-the-expansion-of-basic-education-become-a-global-phenomenon"><a class="deep-link" href="#when-did-the-expansion-of-basic-education-become-a-global-phenomenon"></a>When did the expansion of basic education become a global phenomenon?</h4><p>The second half of the 20th century marked the beginning of education expansion as a global phenomenon. The visualization below, using data from Szirmai (2005)<a id="ref-11" class="ref" href="#note-11"><sup>11</sup></a>, shows government expenditure on education as a share of national income for a selection of low and middle-income countries, together with the corresponding average for high-income countries, for the period 1960-2010. As it can be seen, by 1990 government spending on education in many developing countries was already close to the average observed in developed countries.</p><p>It is important to point out that the remark above makes reference to convergence in expenditure relative to <em>income</em>. To the extent that low-income countries remain poorer than high-income countries, gaps in levels of expenditure per pupil are persistently large. Indeed, cross-country heterogeneity in education expenditure per pupil is currently much higher than heterogeneity in expenditure as share of GDP.<a id="ref-12" class="ref" href="#note-12"><sup>12</sup></a> One factor contributing to the slower convergence of expenditure per pupil in real terms is the fact that teachers&apos; salaries &#x2013; <a href="https://ourworldindata.org/financing-education#where-does-funding-for-education-go-to">the main component of education expenditure</a> &#x2013; are much higher in high-income countries, because labour has a higher opportunity cost in these countries. In general, the opportunity cost of labour is a key variable that governments in developing countries should factor in when deciding whether to expand education now, rather than later.</p><figure data-grapher-src="https://ourworldindata.org/grapher/government-expenditure-on-education-for-selected-countries" class="grapherPreview"><a href="https://ourworldindata.org/grapher/government-expenditure-on-education-for-selected-countries" target="_blank"><div><img src="/exports/government-expenditure-on-education-for-selected-countries_v1_850x600.svg"></div></a></figure><h4 id="education-inequality-is-falling-around-the-world"><a class="deep-link" href="#education-inequality-is-falling-around-the-world"></a>Education inequality is falling around the world</h4><p>An important consequence of the global education expansion is a reduction in education inequality across the globe. The following visualization shows this through a series of graphs plotting changes in the Gini coefficient of the distribution of years of schooling across different world regions. The Gini coefficient is a measure of inequality and higher values indicate higher inequality &#x2013; you can read about the definition and estimation of Gini coefficients in our entry on <a href="https://ourworldindata.org/income-inequality/#the-gini-coefficient">income inequality</a>. The time-series chart below shows inequality by age group. It can be seen that as inequality is falling over time, the level of inequality is higher for older generations than it is for younger generations. We can also see that in the reference period education inequality went down every year, for all age groups and in all world regions.</p><p>Have gains from historical education expansion fully materialized? The breakdown by age gives us a view into the future: as the inequality is lower among today&apos;s younger generations, we can expect the decline of inequality to continue in the future. Thus, further reductions in education inequality are still to be expected within developing countries; and if the expansion of global education can be continued, we can speed up this important process of global convergence.</p><h6>Education Gini coefficients by world region for selected age groups, 1960- 2010 &#x2013; Figure 4 in Crespo Cuaresma et al.

The following visualization show two graphs comparing the concentration of years of education in South Korean between the years 1970 and 2010. To be precise, each of these graphs shows an education Lorenz curve: a plot showing the cumulative percentage of the schooling years across all levels of education on the vertical axis, and the cumulative percentage of the population on the horizontal axis. As it can be seen, in 2010 education was much less concentrated than in 1970, not only because there was a smaller share of individuals without schooling (shown along the bottom of the chart), but also because there was a smaller share of individuals concentrating large proportions of school-years at higher levels of education. Indeed, in only 40 years South Korea was able to double the mean years of schooling (from 6 to 12 years) and at the same time get remarkably close to the 45-degree line marking the hypothetical scenario of perfect equality of schooling. In other entries we show that in this same period South Korea increased drastically its <a href="https://ourworldindata.org/gdp-growth-over-the-last-centuries/#real-gdp-per-capita-around-the-world-ppp-adjusted-since-1000-max-roserref"> GDP per capita</a> while significantly improving health outcomes, such as <a href="https://ourworldindata.org/grapher/child-mortality?country=KOR">child mortality</a>.</p><h6>Inequality of Educational Attainment in South Korea 1970 and 2010<a id="ref-14" class="ref" href="#note-14"><sup>14</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves.png" target="_blank"><img class="aligncenter size-large wp-image-8740" src="https://ourworldindata.org/wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-750x516.png" alt="inequality-of-education-south-korea-lorenz-curves" width="750" height="516" srcset="/wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-32x32.png 32w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-50x50.png 50w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-64x64.png 64w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-96x96.png 96w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-128x128.png 128w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-150x103.png 150w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-400x275.png 400w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-750x516.png 750w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves-768x528.png 768w, /wp-content/uploads/2016/06/Inequality-of-Education-South-Korea-Lorenz-Curves.png 3000w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h3 id="financing-of-education-around-the-world-today"><a class="deep-link" href="#financing-of-education-around-the-world-today"></a>I.2 Financing of Education Around the World Today</h3><h4 id="the-world-is-expanding-funding-for-education-today"><a class="deep-link" href="#the-world-is-expanding-funding-for-education-today"></a>The world is expanding funding for education today</h4><p>The last two decades have seen a small but general increase in the share of income that countries devote to education.

As usual, a selection of countries is shown by default, but other countries can be added by clicking on the relevant option at the top of the chart. Although the data is highly irregular due to missing observations for many countries &#x2013; an issue we discuss in more detail in our section on Data Quality below &#x2013;, we can still observe a broad upward trend for the majority of countries. Specifically, it can be checked that of the 88 countries with available data for 2000/2010, three-fourths increased education spending as a share of GDP within this decade.

The following visualization shows government expenditure on education as a share of total government expenditure. In this case the available data does not suggest a discernible global pattern. For instance, of the 82 countries with available data for 2000 to 2010, only half increased spending on education relative to the other sectors. The data does suggest, however, that there is large and persistent cross-country heterogeneity in the relative importance of education vis-a-vis other sectors, even within developing countries. For example, in 2010 education accounted for about 8% of government spending in the Central African Republic, while it accounted for about 21% in Ghana.</p><figure data-grapher-src="https://ourworldindata.org/grapher/share-of-education-in-government-expenditure" class="grapherPreview"><a href="https://ourworldindata.org/grapher/share-of-education-in-government-expenditure" target="_blank"><div><img src="/exports/share-of-education-in-government-expenditure_v1_850x600.svg"></div></a></figure><h4 id="european-countries-tend-to-assign-a-lower-share-of-public-budgets-to-education-relative-to-the-amount-of-their-income-that-is-devoted-to-education"><a class="deep-link" href="#european-countries-tend-to-assign-a-lower-share-of-public-budgets-to-education-relative-to-the-amount-of-their-income-that-is-devoted-to-education"></a>European countries tend to assign a lower share of public budgets to education, relative to the amount of their income that is devoted to education</h4><p>Generally speaking, countries that spend a large share of their income on education also tend to prioritize education highly within their budgets. The following visualization presents a snapshot of government spending on education around the world for the year 2010. Specifically, this graph plots government expenditure on education as a share of GDP in the vertical axis, and government expenditure on education as a share of total government expenditure in the horizontal axis. Each dot on this chart represents a different country, with the assigned colors denoting different world regions. As we can see, there is a positive correlation, but regional differences are stark: for almost every level of spending as a share of GDP along the horizontal axis, European countries (marked in light orange) spend a smaller budget share on education.</p><figure data-grapher-src="https://ourworldindata.org/grapher/share-edu-spending-gdp-vs-share-edu-total-spending" class="grapherPreview"><a href="https://ourworldindata.org/grapher/share-edu-spending-gdp-vs-share-edu-total-spending" target="_blank"><div><img src="/exports/share-edu-spending-gdp-vs-share-edu-total-spending_v1_850x600.svg"></div></a></figure><h4 id="in-european-countries-the-weight-of-primary-education-within-total-education-spending-is-lower-than-in-other-countries"><a class="deep-link" href="#in-european-countries-the-weight-of-primary-education-within-total-education-spending-is-lower-than-in-other-countries"></a>In European countries the weight of primary education within total education spending is lower than in other countries</h4><p>In comparison to countries where education started expanding later, European countries tend to assign relatively more of their government education budgets to the secondary and tertiary levels, while at the same time devoting relatively less of their general government budgets to education as a whole. This can be appreciated in the following visualization, where the priorization of primary education (i.e. the share of primary education within the education budget) is plotted against the overall priorization of education (i.e. the share of education within the entire government budget). It can be seen that European countries (marked again in light orange) are mostly located in the bottom-left.

The top chart in this figure, corresponding to high income countries, shows a very clear pattern: households contribute the largest share of expenses in tertiary education, and the smallest share in primary education. Roughly speaking, this pattern tends to be progressive, since students from wealthier households are more likely to attend tertiary education, and those individuals who attend tertiary education are likely to perceive large private benefits (more on this in our entry on <a href="https://ourworldindata.org/skill-premium-income-by-education/">Skill Premium</a>).<a id="ref-16" class="ref" href="#note-16"><sup>16</sup></a> In contrast, the bottom chart shows a very different picture: in several low-income countries households contribute proportionally more to primary education than to higher levels.

Today, public resources still dominate funding for the primary, secondary and post-secondary non-tertiary education levels in these countries. While in the last decade the share of public funding for these levels of education has decreased slightly, the broad pattern is remarkably stable.

The visualization below presents expenditure on pre-primary educational institutions as a share of GDP across the OECD. As it can be seen, publicly funded pre-primary education tends to be more strongly developed in the European than the non-European countries of the OECD. In fact, the OECD reports that in Europe the concept of universal access to education for 3-6 year-olds is generally accepted: most countries in this region provide all children with at least two years of free, publicly funded pre-primary education in schools before they begin primary education.

The following chart shows total OECD development assistance flows for education by level, in constant 2013 US dollars, for the period 2002-2013. As it can be seen, there are two distinct periods: in 2003-2010 flows for education increased substantially, more than doubling in real terms across all levels of education; and in the years 2010-2013 funding for basic education <em>decreased</em>, while funding for secondary and post-secondary education remained relatively constant. For many low income countries, where development assistance contributes a substantial share of funding for education, this marked change in trends is important.

Specifically, the share of development assistance for primary education going to sub-Saharan Africa has been decreasing sharply since the agreement of the Millennium Development Goals. The following chart shows this: sub-Saharan Africa&#x2019;s share in total aid to primary education declined from 52 percent in 2002 to 30 percent in 2013, while the continent&#x2019;s share in the total number of out-of-school children rose from 46 percent to 57 percent. This pattern is something specific to the education sector within the broader development assistance landscape: in the healthcare sector the overall slowdown of flows started a couple of years later, was less abrupt, and affected proportionally less the sub-Saharan countries.<a id="ref-21" class="ref" href="#note-21"><sup>21</sup></a> Indeed, recent studies further highlight that development assistance for education is significantly different to assistance for healthcare in other ways: the education sector attracts less earmarked funding through multilaterals, and includes a smaller proportion of resources that developing governments can directly control for programming.<a id="ref-22" class="ref" href="#note-22"><sup>22</sup></a> You can read more about development assistance for healthcare in our entry on <a href="https://ourworldindata.org/financing-healthcare/#recent-developments-flows-of-global-health-financing">Financing Healthcare</a>.</p><h6>Share of primary education disbursements from development assistance going to Sub-Saharan Africa, 2002-2013 &#x2013; Figure 2.6 in Steer and Smith (2015)<a id="ref-23" class="ref" href="#note-23"><sup>23</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/Brookings_ODA_EduAfrica.png" target="_blank"><img class="aligncenter size-large wp-image-8094" src="https://ourworldindata.org/wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-750x410.png" alt="Brookings_ODA_EduAfrica" width="750" height="410" srcset="/wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-32x32.png 32w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-50x50.png 50w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-64x64.png 64w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-96x96.png 96w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-128x128.png 128w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-150x82.png 150w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-400x219.png 400w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-750x410.png 750w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica-768x420.png 768w, /wp-content/uploads/2016/06/Brookings_ODA_EduAfrica.png 1346w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h4 id="development-assistance-priorities-have-a-scope-for-increasing-or-reducing-expenditure-inequalities"><a class="deep-link" href="#development-assistance-priorities-have-a-scope-for-increasing-or-reducing-expenditure-inequalities"></a>Development assistance priorities have a scope for increasing or reducing expenditure inequalities</h4><p>In the <a href="https://ourworldindata.org/financing-education#historical-perspective.">Historical Perspective</a> section above, we mentioned that public spending on education has translated, in the long run, into lower inequality in education outcomes across most of the world. But for any given country, with a determined income distribution and demographic structure, the extent to which public spending on education contributes to reduce inequality depends crucially on the way in which spending is focused across education levels. The recent UNICEF report <a href="http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf">The Investment Case for Education and Equity</a> shows that in low income countries, on average 46 percent of public resources are allocated to the 10 percent of students who are most educated &#x2013; while this figure goes down to 26 and 13 percent in lower-middle and upper-middle income countries respectively. The following visualization shows further details on the concentration of public spending across different countries. The vertical axis shows the percentage of public education resources going to the 10% most educated or 10% least educated students &#x2013; as we can see expenditure is heavily concentrated at the top in many low income countries.</p><p>The earlier remarks about trends in international education financing flows (namely that aid is very important in low-income countries, and that a relatively low and shrinking share of aid is going to primary levels), suggest that inequality in public spending will worsen in low income countries. Yet development assistance priorities have a scope for changing this.<a id="ref-24" class="ref" href="#note-24"><sup>24</sup></a></p><h6>Percentage of public education resources going to the 10% most educated or 10% least educated students &#x2013; Figure 29 in <a href="http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf">The Investment Case for Education and Equity (UNICEF - 2015)</a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration.png" target="_blank"><img class="aligncenter size-large wp-image-8141" src="https://ourworldindata.org/wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-531x550.png" alt="UNICEF Education Expenditure Concentration" width="531" height="550" srcset="/wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-32x32.png 32w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-50x50.png 50w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-64x64.png 64w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-96x96.png 96w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-128x128.png 128w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-145x150.png 145w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-386x400.png 386w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-531x550.png 531w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration-768x795.png 768w, /wp-content/uploads/2016/06/UNICEF-Education-Expenditure-Concentration.png 1538w" sizes="(min-width: 800px) 50vw, 100vw"></a></p></section>

Private returns to education include higher wages and better employment prospects (as we discuss in our entry on <a href="https://ourworldindata.org/returns-to-education">Returns to Education</a>). Social return include pro-social behaviour (e.g. volunteering, political participation) and interpersonal <a href="https://ourworldindata.org/trust/">trust</a>. The following chart uses OECD results from the Survey of Adult Skills to show how self-reported trust in others correlates with educational attainment. More precisely, this chart plots the percentage-point difference in the likelihood of reporting to trust others, by education level of respondents. Those individuals with upper secondary or post-secondary non-tertiary education are taken as the reference group, so the percentage point difference is expressed in relation to this group. As we can see, in all countries those individuals with tertiary education were by far the group most likely to report trusting others. And in almost every country, those with post-secondary non-tertiary education were more likely to trust others than those with primary or lower secondary education. The OECD&apos;s report <a href="http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1">Education at a Glance (2015)</a> provides similar descriptive evidence for other social outcomes. The conclusion is that adults with higher qualifications are more likely to report desirable social outcomes, including good or excellent health, participation in volunteer activities, interpersonal trust, and political efficacy. And these results hold after controlling for literacy, gender, age and monthly earnings.</p><h6>Likelihood of reporting to trust others, by educational attainment, OECD 2012 &#x2013; Figure A8.4 in <a href="http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1">Education at a Glance (2015)</a><a id="ref-26" class="ref" href="#note-26"><sup>26</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/OECD_Education_Trust.png" target="_blank"><img class="aligncenter size-large wp-image-8134" src="https://ourworldindata.org/wp-content/uploads/2016/06/OECD_Education_Trust-750x441.png" alt="OECD_Education_Trust" width="750" height="441" srcset="/wp-content/uploads/2016/06/OECD_Education_Trust-32x32.png 32w, /wp-content/uploads/2016/06/OECD_Education_Trust-50x50.png 50w, /wp-content/uploads/2016/06/OECD_Education_Trust-64x64.png 64w, /wp-content/uploads/2016/06/OECD_Education_Trust-96x96.png 96w, /wp-content/uploads/2016/06/OECD_Education_Trust-128x128.png 128w, /wp-content/uploads/2016/06/OECD_Education_Trust-150x88.png 150w, /wp-content/uploads/2016/06/OECD_Education_Trust-400x235.png 400w, /wp-content/uploads/2016/06/OECD_Education_Trust-750x441.png 750w, /wp-content/uploads/2016/06/OECD_Education_Trust-768x451.png 768w, /wp-content/uploads/2016/06/OECD_Education_Trust.png 2188w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h4 id="do-countries-that-spend-more-public-resources-on-education-tend-to-have-better-education-outcomes"><a class="deep-link" href="#do-countries-that-spend-more-public-resources-on-education-tend-to-have-better-education-outcomes"></a>Do countries that spend more public resources on education tend to have better education outcomes?</h4><p>Education outcomes are typically measured via &apos;quantity&apos; output (e.g. years of schooling) and <a href="https://ourworldindata.org/quality-of-education">&apos;quality&apos; output</a> (e.g. learning outcomes, such as test scores from the Programme for International Student Assessment &#x2013; PISA). The following visualization presents three scatter plots using 2010 data to show the cross-country correlation between (i) education expenditure (as a share of GDP), (ii) mean years of schooling, and (iii) mean PISA test scores. At a cross-sectional level, expenditure on education correlates positively with both quantity and quality measures; and not surprisingly, the quality and quantity measures also correlate positively with each-other. But obviously correlation does not imply causation: there are many factors that simultaneously affect education spending and outcomes. Indeed, these scatterplots show that despite the broad positive correlation, there is substantial dispersion away from the trend line &#x2013; in other words, there is substantial variation in outcomes that does not seem to be captured by differences in expenditure. This motivates the question below.</p><h6>Correlation between education outcomes and education expenditure (2010 data)<a id="ref-27" class="ref" href="#note-27"><sup>27</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure.png" target="_blank"><img class="aligncenter size-large wp-image-8101" src="https://ourworldindata.org/wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-750x546.png" alt="Edu_OutcomesVsExpenditure" width="750" height="546" srcset="/wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-32x32.png 32w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-50x50.png 50w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-64x64.png 64w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-96x96.png 96w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-128x128.png 128w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-150x109.png 150w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-400x291.png 400w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-750x546.png 750w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure-768x559.png 768w, /wp-content/uploads/2016/06/Edu_OutcomesVsExpenditure.png 1040w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h4 id="does-cross-country-variation-in-government-education-expenditure-explain-cross-country-differences-in-education-outcomes"><a class="deep-link" href="#does-cross-country-variation-in-government-education-expenditure-explain-cross-country-differences-in-education-outcomes"></a>Does cross-country variation in government education expenditure explain cross-country differences in education outcomes?</h4><p>The following visualization presents the relationship between PISA reading outcomes and average education spending per student, splitting the sample of countries by income levels. It shows that income is an important factor that affects both expenditure on education and education outcomes: we can see that above a certain national income level, the relationship between PISA scores and education expenditure per pupil becomes virtually inexistent. Several studies with more sophisticated econometric models corroborate the fact that expenditure on education does not explain well cross-country differences in learning outcomes.<a id="ref-28" class="ref" href="#note-28"><sup>28</sup></a> You can read more about test scores and learning outcomes in our entry on <a href="https://ourworldindata.org/quality-of-education-drop-out-rates/">Quality of Education</a>.</p><h6>Average reading performance in PISA and average spending per student from the age of 6 to 15 - Figure 1 in OECD (2012)<a id="ref-29" class="ref" href="#note-29"><sup>29</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student.png" target="_blank"><img class=" size-large wp-image-5718 aligncenter" src="https://ourworldindata.org/wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-750x492.png" alt="Average reading performance in PISA and average spending per student" width="750" height="492" srcset="/wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-32x32.png 32w, /wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-64x64.png 64w, /wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-96x96.png 96w, /wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-128x128.png 128w, /wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-150x98.png 150w, /wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-400x263.png 400w, /wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student-750x492.png 750w, /wp-content/uploads/2013/07/ourworldindata_average-reading-performance-in-pisa-and-average-spending-per-student.png 1345w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h4 id="what-inputs-enter-the-education-production-function"><a class="deep-link" href="#what-inputs-enter-the-education-production-function"></a>What inputs enter the &apos;education production function&apos;?</h4><p>The fact that expenditure on education does not explain well cross-country differences in learning outcomes is indicative of the intricate nature of the process through which such outcomes are produced.

The following table summarizes results from the systematic review in Hanushek (2006)<a id="ref-31" class="ref" href="#note-31"><sup>31</sup></a>. In this table, the left-hand side summarizes results from econometric studies focusing on developing countries, while the right-hand side presents evidence from the US (where studies have concentrated extensively). We can see that for all listed inputs and across all countries, the share of studies that have found a positive effect is small &#x2013; in fact, the majority of studies find either no effect, or a negative effect. This clearly does not mean that these classroom resources are not important, but rather that it is very difficult to know with confidence when and where they are a binding constraint to improve learning outcomes. A first conclusion, therefore, seems to be that context and input mix are fundamental to improving outcomes &#x2013; even in developing countries where the expected returns to additional resources is large across the board.</p><p>Taking the ratio of positive to negative effects detected in the literature as a proxy for what tends to work best, we can derive a second conclusion from the table below: spending more resources on better teachers (i.e. improving teacher experience and teacher education) tends to work better to improve learning outcomes than simply increasing the number of teachers per pupil. And this seems to be true both in developed and developing countries. This last conclusion is consistent with the main message from the OECD&apos;s report <a href="http://www.oecd.org/pisa/pisaproducts/pisainfocus/49685503.pdf">Does money buy strong performance in PISA?</a>, which points out that countries that prioritised the quality of teachers over class sizes performed better in PISA tests.<a id="ref-32" class="ref" href="#note-32"><sup>32</sup></a> And it is also consistent with a recent high-quality study on the impact of teacher quality on test scores using data from the US, which suggests that improvements in teacher quality can causally raise students&#x2019; test scores (evidence from Chetty et al.

Recent evidence from policy &apos;experiments&apos; in developing countries suggests that remedial teaching, in the form of assistants teaching targeted lessons to the bottom of the class, can yield substantial improvements in learning outcomes. The following visualization summarizes the effects of four different policy treatments within the so-called Teacher Community Assistant Initiative (TCAI) in Ghana &#x2013; this is an initiative that evaluated four different such remedial teaching interventions.<a id="ref-35" class="ref" href="#note-35"><sup>35</sup></a> The units in this figure are standard deviations of test results. The first two sets of estimates correspond to the test-score impacts of enabling community assistants to provide remedial instruction specifically to low-performing children, either during school, or after school. The third set of estimates corresponds to test-score impacts of providing a community assistant and reducing class size, without targeting instruction to low-performing pupils. And the last set of results corresponds to testing the effect of training teachers to provide small-group instruction targeted at pupils&#x2019; actual learning levels.</p><p>As we can see, while all interventions had a positive effect, the lowest impacts &#x2013; across all tests &#x2013; come from the non-targeted &apos;normal curriculum&apos; intervention that reduced class sizes, and from the intervention that provided training to teachers on how to engage in targeted remedial teaching themselves. This suggests that the improvements in outcomes were caused by the combination of targeted instruction and TCAs who, unlike teachers, were specifically dedicated to this purpose. These results are consistent with findings from across Africa, suggesting that teaching at the right level causes better learning outcomes in a cost-effective way (see Glewwe and Muralidharan 2016<a id="ref-36" class="ref" href="#note-36"><sup>36</sup></a> for further details on this evidence).</p><h6>Summary of treatment effects from the Teacher Community Assistant Initiative (TCAI) in Ghana (estimates by test subject in standard deviations) &#x2013; Page 2 in Innovations for Poverty Action (2014)<a id="ref-37" class="ref" href="#note-37"><sup>37</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL.png" target="_blank"><img class="aligncenter size-large wp-image-8202" src="https://ourworldindata.org/wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-750x536.png" alt="TCAI_RemedialTeaching_JPAL" width="750" height="536" srcset="/wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-32x32.png 32w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-50x50.png 50w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-64x64.png 64w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-96x96.png 96w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-128x128.png 128w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-150x107.png 150w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-400x286.png 400w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-750x536.png 750w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL-768x549.png 768w, /wp-content/uploads/2016/06/TCAI_RemedialTeaching_JPAL.png 1402w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h4 id="are-pay-for-performance-teacher-contracts-an-effective-instrument-to-improve-learning-outcomes"><a class="deep-link" href="#are-pay-for-performance-teacher-contracts-an-effective-instrument-to-improve-learning-outcomes"></a>Are pay-for-performance teacher contracts an effective instrument to improve learning outcomes?</h4><p>We have already made the point that the bulk of education expenditure goes specifically towards financing teachers. And we have also pointed out that improving teacher quality may be a particularly good instrument to improve teaching outcomes. This leads to a natural question: are pay-for-performance teacher contracts an effective instrument to improve learning outcomes? A growing body of literature in the economics of education has started using randomized control trials (i.e. policy &apos;experiments&apos;) to answer this question. Glewwe and Muralidharan (2016)<a id="ref-38" class="ref" href="#note-38"><sup>38</sup></a> provide the following account of the available evidence:</p><blockquote><p><em>&quot;Results suggest that even modest changes to compensation structures to reward teachers on the basis of objective measures of performance (such as attendance or increases in student test scores) can generate substantial improvements in learning outcomes at a fraction of the cost of a &quot;business as usual&quot; expansion in education spending. However, not all performance pay programs are likely to be effective, so it is quite important to design the bonus formulae well and to make sure that these designs reflect insights from economic theory.&quot;</em> <a id="ref-39" class="ref" href="#note-39"><sup>39</sup></a></p></blockquote><p>The conclusion is that well-designed pay-for-performance contracts are a cost-effective instrument to boost test scores; but this does not mean that they are necessarily effective at achieving other &#x2013; perhaps equally important &#x2013; objectives of time spent in school. In simple words, it is possible that pay-for-performance yields &apos;teaching to the test&apos;. Alternative incentive mechanisms, such as community-based monitoring of teachers, have been proposed as an alternative. Glewwe and Muralidharan (2016) also provide a review of the &#x2013; somewhat limited &#x2013; available evidence on such alternative incentive mechanisms.<a id="ref-40" class="ref" href="#note-40"><sup>40</sup></a></p><h3 id="household-inputs"><a class="deep-link" href="#household-inputs"></a>II.3 Household inputs</h3><h4 id="school-attendance-and-student-effort-are-responsive-to-incentives"><a class="deep-link" href="#school-attendance-and-student-effort-are-responsive-to-incentives"></a>School attendance and student effort are responsive to incentives</h4><p>Demand-side inputs are as important as supply-side inputs to produce education. Attending school and exerting effort are perhaps the most obvious examples: without these inputs even the best endowed schools will fail to deliver good outcomes. The table below summarizes information on different demand-side investments that have shown to successfully improve quality and quantity outcomes. More precisely, this table gathers evidence from randomized control trials in developing countries, as per the review in Glewwe and Muralidharan (2016). The reported figures correspond to positive/negative significant/insignificant estimates across a set of available experimental studies (bear in mind some studies estimate more than one effect &#x2013; e.g. by measuring outcomes at several points in time). As we can see, the evidence suggests that interventions that increase the benefits of attending school &#x2013; such as conditional cash transfers &#x2013; are likely to increase student time in school. And those that increase the benefits of higher effort and better academic performance &#x2013; such as merit scholarships &#x2013; are likely to improve learning outcomes (see Glewwe and Muralidharan 2016 for further details on the underlying policy interventions, plus further evidence and discussion of results).</p><h6>Summary of impacts for selected demand-side interventions on education outcomes in developing countries &#x2013; based on Tables 4 and 5 from Glewwe and Muralidharan (2016)<a id="ref-41" class="ref" href="#note-41"><sup>41</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1.png" target="_blank"><img class="aligncenter size-large wp-image-8125" src="https://ourworldindata.org/wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-750x338.png" alt="Glewwe2016_DemandInterventions_RCTs" width="750" height="338" srcset="/wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-32x32.png 32w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-50x50.png 50w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-64x64.png 64w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-96x96.png 96w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-128x128.png 128w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-150x68.png 150w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-400x180.png 400w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-750x338.png 750w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1-768x346.png 768w, /wp-content/uploads/2016/06/Glewwe2016_DemandInterventions_RCTs-1.png 2984w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><h4 id="targeting-health-problems-can-be-a-particularly-cost-effective-way-of-increasing-school-attendance"><a class="deep-link" href="#targeting-health-problems-can-be-a-particularly-cost-effective-way-of-increasing-school-attendance"></a>Targeting health problems can be a particularly cost-effective way of increasing school attendance</h4><p>In many low-income countries, health problems are an important factor preventing children from attending school. The following visualization presents a comparison of the impact that a number of different health interventions have achieved in different countries &#x2013; together with some non-health-related interventions that serve as reference. The hight of each bar in this graph reflects the additional school years achieved per hundred dollars spent on the corresponding intervention; so these estimates can be interpreted as a measure of how cost-effective the different interventions are.<a id="ref-42" class="ref" href="#note-42"><sup>42</sup></a> We see that treating children for intestinal worms (labeled &apos;deworming&apos; in the chart) led to an additional 13.9 years of education for every $100 spent in Kenya; while a program targeting anaemia (labeled &apos;iron fortification&apos;) led to 2.7 additional years per $100 in India. These interventions seem to be much more cost-effective to improve test scores than conditional cash transfers, free school uniforms, or merit scholarships (further details on all interventions available from Dhaliwal et al. 2012<a id="ref-43" class="ref" href="#note-43"><sup>43</sup></a>). Of course, ranking these interventions is not trivial since most programmes achieve multiple outcomes &#x2013; indeed, we have already discussed that remedial teaching is generally effective to increase test-scores, although here we see a particular instance where it had no impact on school attendance. Nevertheless, health interventions seem to be particularly interesting, since they lead to substantial achievements in both education <em>and</em> health outcomes (for a recent analysis of the literature on the impacts of mass deworming see Croke et al. 2016<a id="ref-44" class="ref" href="#note-44"><sup>44</sup></a>).</p><h6>Impact of selected demand-side interventions on school participation in developing countries (Additional years of student participation per $100) &#x2013; Figure 8.1 in Dhaliwal et al.

To a great extent, this is what drives large and remarkably persistent gaps in the education achievement between individuals in the same country, but in different socioeconomic environments. Cunha et al. (2006) provide a detailed account of the theory and evidence behind this claim, and discuss its implications for the design of education policies. Below we provide a chart showing the impacts from the Perry Preschool Program &#x2013; a flagship experimental intervention study, designed to test the impact of pre-school education on subsequent education outcomes.<a id="ref-46" class="ref" href="#note-46"><sup>46</sup></a> The chart shows that disadvantaged children participating in the pre-school program (the &apos;treatment group&apos;) had higher grades and were more likely to graduate from high school than the reference control group. Moreover, they spent substantially less time in special education. Other programs have similarly shown evidence of very large and persistent returns to early education interventions.</p><h6>Educational effects from participating in the Perry Preschool Program &#x2013; Figure 14B in Cunha et al (2006)<a id="ref-47" class="ref" href="#note-47"><sup>47</sup></a>.</h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/Cunha2006_Preschool_Impact.png" target="_blank"><img class="aligncenter size-large wp-image-8128" src="https://ourworldindata.org/wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-750x376.png" alt="Cunha2006_Preschool_Impact" width="750" height="376" srcset="/wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-32x32.png 32w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-50x50.png 50w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-64x64.png 64w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-96x96.png 96w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-128x128.png 128w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-150x75.png 150w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-400x201.png 400w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-750x376.png 750w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact-768x386.png 768w, /wp-content/uploads/2016/06/Cunha2006_Preschool_Impact.png 2036w" sizes="(min-width: 800px) 50vw, 100vw"></a></p></section>

In practice, however, many countries under report these specific figures.</p><h3 id="measurement-limitations"><a class="deep-link" href="#measurement-limitations"></a>III.3 Measurement limitations</h3><p>The UIS has been maintained since 1999 with the intent of providing comparable expenditure figures across countries and time, and its estimates rely on reports submitted by ministries and national statistics offices. Since reporting is delegated typically to ministries of education, in some instances data on total public expenditure on education fails to represent spending by other ministries that also have budgets for education. Additionally, since not all countries have (or update) national education accounts, the UIS attempts to generate estimates and impute missing data using information from national publications, official websites and other sources. However, the UIS dataset has several missing observations, particularly for years prior to 2010.</p><p>To gauge the extent to which UIS data is reliable, the following visualization shows the proportions of regular and irregular data that countries make available (where &#x2018;Regular&#x2019; means data is available at least once every 3 years; and &#x2018;Irregular&#x2019; means data is available less frequently than every 3 years). As it can be seen, the picture is not particularly encouraging: less than half of the countries reported regularly data on total government expenditure on education over the reference period.</p><h6>Availability of education financing data in the UIS database, 2005-2013, as a percentage of all (214) countries &#x2013; Figure 1 in UNESCO&#x2013;UIS (2016)<a id="ref-49" class="ref" href="#note-49"><sup>49</sup></a></h6><p><a href="https://ourworldindata.org/wp-content/uploads/2016/06/UIS-Data-Quality.png" target="_blank"><img class="aligncenter size-large wp-image-8149" src="https://ourworldindata.org/wp-content/uploads/2016/06/UIS-Data-Quality-750x513.png" alt="UIS Data Quality" width="750" height="513" srcset="/wp-content/uploads/2016/06/UIS-Data-Quality-32x32.png 32w, /wp-content/uploads/2016/06/UIS-Data-Quality-50x50.png 50w, /wp-content/uploads/2016/06/UIS-Data-Quality-64x64.png 64w, /wp-content/uploads/2016/06/UIS-Data-Quality-96x96.png 96w, /wp-content/uploads/2016/06/UIS-Data-Quality-128x128.png 128w, /wp-content/uploads/2016/06/UIS-Data-Quality-150x103.png 150w, /wp-content/uploads/2016/06/UIS-Data-Quality-400x273.png 400w, /wp-content/uploads/2016/06/UIS-Data-Quality-750x513.png 750w, /wp-content/uploads/2016/06/UIS-Data-Quality-768x525.png 768w, /wp-content/uploads/2016/06/UIS-Data-Quality.png 1612w" sizes="(min-width: 800px) 50vw, 100vw"></a></p><p>Apart from the above-mentioned issues regarding availability of data, international cross-country comparisons of education financing estimates are also problematic due to lack of consistency in classification of expenditures, especially on the borderline of education services. While this is less problematic than in other sectors, such as healthcare, there are still some difficult cases &#x2013; such as classifying expenditure for teaching hospitals, or expenditure on ancillary services such as transportation.

This evidently does not mean that resources <em>should</em> be shifted – low income countries and aid donors may have other objectives apart from reducing inequality. But the case for reducing inequality at the bottom is very strong, and some studies suggest that returns to education at the primary level might be higher than at post-primary levels in low income countries (for a discussion of the vast literature on returns to education, and the ongoing debate on the validity of estimates, see Heckman, J. J., Lochner, L. J., &amp; Todd, P. E. (2006). Earnings functions, rates of return and treatment effects: The Mincer equation and beyond. Handbook of the Economics of Education, 1, 307-458. ).</p></li><li id="note-25"><p>That positive externalities justify government intervention in the provision of education is essentially an efficiency argument. The logic is that individuals may not spend enough on education because they fail to internalize the positive effect that their education has on other people. But there are, of course, also equity arguments to justify government intervention in the provision of education – for instance, reducing inequality in education may be of intrinsic value, or may be instrumental in reducing inequalities in other outcomes.</p></li><li id="note-26"><p>As per the source notes: "Percentage-point difference reflects the relative change of reporting to trust others compared to the reference category. For example, in Norway, the percentage of individuals with tertiary education reporting to trust others increases by 20 percentage points compared to someone who has upper secondary or post-secondary non-tertiary education. Similarly, after accounting for literacy proficiency, the percentage of individuals with tertiary education increases by 16 percentage points compared to someone who has upper secondary or post-secondary non-tertiary education."</p></li><li id="note-27"><p>Data on expenditure corresponds to 2010 total government education expenditure across all levels, as a share of GDP (source: World Bank Education Statistics).

The treatment consisted of a daily 2.5-hour classroom session on weekday mornings and a weekly 90-minute home visit by the teacher on weekday afternoons to involve the mother in the child's educational process.
