Understanding the mechanisms underlying peer group effects: The role of friendships in determining adolescent outcomes
Jason Fletcher, Stephen L. Ross 03 November 2013
There is a large and growing literature on peer effects, but much less is known about the role of friendships and social relationships in student outcomes. The best evidence on the mechanisms behind aggregate peer effects suggests an important role for discipline and disruption. Very recent research suggests that friends can also have a substantial effect on student outcomes, and in many cases the effect of friends appears to be independent of aggregate peer effects.
Over the last decade, research on peer effects in secondary education has flourished – in part because of the within-school/across-cohort design for identifying peer effects popularised in early work by Hoxby (2000), and partly due to the increasing availability of quality data on K-12 students in the US and internationally. The cohort approach to studying peer effects exploits the idea that when choosing schools, parents cannot easily observe the attributes of the specific cohorts to which their children will belong.

Do elite universities admit the academically best students?
Debopam Bhattacharya 13 April 2013
Elite universities’ admission policies are perennially surrounded by controversy given the thorny efficiency and equity issues involved. This column discusses research into such policies focusing on the degree of meritocracy and non-academic bias. It suggests that men and private-school applicants have somewhat higher application success rates despite being held to higher academic admission standards.
The undergraduate admissions process at elite universities, owing to its implications for socioeconomic mobility, is subjected to significant public scrutiny in the UK. Social commentators and politicians routinely call for 'scientific assessment' of existing admission methods (Hewstone 2013) while news media and thinktanks regularly publish reports documenting what appear superficially to be 'unfair' admission practices at selective universities.

The trend reversal in income inequality and returns to education: How bad is this good news for Latin America?
Augusto de la Torre, Julián Messina 07 March 2013
The last decade has seen unprecedented economic and social achievements in Latin America. This column investigates the relationship between changes in the labour market and the drop in income inequality across the continent. There is certainly room for more research to help us better understand Latin America’s spectacular decline in income inequality, but what is clear is that the good news is tempered by the fact that the specialisation of the region’s economies are relatively low in skill intensity and therefore productivity.
Latin America witnessed unprecedented economic and social achievements during the last decade. In particular, the year 2003 appears as an important inflexion point for the region’s economic history, a point that we have highlighted in several World Bank publications1. Specifically, moderate poverty (less than US$4 purchasing power parity per capita, which leveled around 45% of total population during the 1990s and until 2003, steadily falls to less than 30% by 2011, allowing more than 70 million Latin Americans to leave poverty in less than a decade.

The long-run gains of not mixing genders in high-school classes
Massimo Anelli, Giovanni Peri 23 February 2013
What causes fewer women than men to choose high-earning potential subjects such as engineering, economics or science at undergraduate level? This column presents new evidence from an accidental natural experiment in Italy, suggesting mixed-gender classes at the high-school level reduce the number of women pursuing these subjects. These results suggest that gender-separated classrooms are an effective way to increase women’s career opportunities and salaries.

The reduction of school days in Japan increased educational inequality
Daiji Kawaguchi 02 February 2013
Japan switched to five-day weeks for its primary and junior high schools and saw an increase in educational inequality. This column discusses new evidence suggesting a loose tie between number of days at school and inequality. Importantly, this tie reflects the fact that homes with university-educated parents tend to offset the official reduction in hours with additional tuition.
One of the major objectives of compulsory education is to assure uniform educational opportunities for all children regardless of their socioeconomic background. For that reason, most advanced countries provide compulsory education as well as textbooks free of charge. Getting education policy right for those at an early age is also important for competitiveness in the global knowledge economy (Murtin and Viarengo 2013).

Russia aims to diversify its economy and reduce its dependence on natural resources. Despite laudable aims, this column argues that progress has been sluggish. Longstanding obstacles of corruption, low business-entry rates and weak competition afflict other countries that, like Russia, are in transition. Yet Russia comes pretty much bottom of the class. Crucially, the fact that economic diversification requires improvements to education and skills acquisition has been somewhat overlooked by the state. What attempts the state has made, such as supporting technology innovation, appear to have been ineffectual and, at times, counterproductive. Going forward, Russia would do well to focus on improving incentives for market-relevant research and development, complemented by private sector-led sources of finance for early-stage firms.
Russia aims to diversify its economy, thereby moving away from its dependence on oil and gas. Despite much political rhetoric, our research (European Bank for Reconstruction and Development 2012) indicates that, to date, relatively little has been achieved. Oil and gas still account for nearly 70% of total merchandise exports and around a half of the federal budget. Figure 1 shows the increasing share of minerals in total exports when measured in constant prices.

The expansion and convergence of compulsory schooling: Lessons for developing countries
Fabrice Murtin, Martina Viarengo 18 January 2013
A workforce’s cognitive skills and ability to learn are regarded as crucial factors for countries hoping to develop and become competitive in the global knowledge economy. This column argues that many developing countries‘ basic educational attainment and learning outcomes remain wanting. Taking a look at Europe’s historical record can shed light on the developing-country context, and evidence suggests that simply expanding an ill-functioning educational system will be wasteful. It’s advisable for policymakers to pursue institutional reform aimed at cost-efficiency before they begin implementing school reforms.
One goal of the UN’s Millennium Declaration is “achieving universal primary education” by 2015 (UN 2012). Yet, according to recent statistics, 61 million children of primary school age are not enrolled in school (UNESCO 2012), and 12% do not complete primary education (World Bank 2012). Drop-off rates significantly increase in developing countries during the transition from primary to secondary school.

The impact of immigration on the educational attainment of natives
Jennifer Hunt 17 November 2012
Are poorly-educated immigrants’ kids dragging native classmates down? Or do schoolchildren push themselves when new, smarter immigrants join their class? This column argues that although child immigrants may sometimes bring down native minorities, on the whole, poorly educated natives upgrade their education in response to new immigrants in the classroom.
The increase in wage inequality in a large number of developed countries has heightened the importance of ensuring all children complete at least an apprenticeship or 12 years of high school. At the same time, parents in countries with high levels of immigration of low-skilled workers fear that the presence of immigrant children in the classroom lowers the quality of education for native students. If this concern is well founded, rising immigration could reduce native high school graduation rates as the benefit of an addition year of schooling falls.
Who lives longer?
Josep Pijoan-Mas, Víctor Ríos-Rull 30 September 2012
What explains differences in life expectancy at age 50? This column looks at the effect of wealth, education, and marital status. It finds that by far the most important factor is education, and explores what this might mean for policy.
Economists have long been worried about income inequality and its effects on welfare. For instance, workers with a college degree earn on average much more than those who did not complete high school. This disparity translates into large differences in consumption levels and hence welfare (see, for instance, Heathcote et al. 2010). We argue, however, that these welfare differences are dwarfed by the differences in longevity between individuals in different socioeconomic groups, and mainly by differences in longevity between individuals of different educational levels.

What’s the use of economics? Introduction to the Vox debate
Diane Coyle 19 September 2012
Five years after Lehman’s collapse, economics is under fire both from outside and inside the profession for irrelevance, arrogance and more. This column introduces a new Vox debate focused on two questions: What’s the use of economics, and how should we be teaching it to the next generation?
This column is a lead commentary in the VoxEU Debate "What's the use of economics?"
