This paper studies the impact of diversity in cognitive ability among members of a team on their performance. We conduct a large field experiment in which teams start up and manage real companies under identical circumstances. Exogenous variation in – otherwise random – team composition is...

One of the most salient and relevant dimensions of team heterogeneity is ethnicity. We measure the causal impact of ethnic diversity on the performance of business teams using a randomized field experiment. We follow 550 students who set up 45 real companies as part of their curriculum in an...

We analyse the role of training in mitigating the negative impact of technical and organizational changes on the employment prospects of older workers. Using a panel of French firms in the late 1990s, we first estimate wage bill share equations for different age groups. Consistently with what is...

This paper considers what has hitherto been a relatively neglected subject in the wage inequality literature, albeit one that has been becoming more important over time, namely the role played by increases in postgraduate education. We document increases in the number of workers with a...

Although many countries are aggressively implementing the One Laptop per Child (OLPC) program, there is a lack of empirical evidence on its effects. This paper presents the impact of the first large-scale randomized evaluation of the OLPC program, using data collected after 15 months of...

Computers are an important part of modern education, yet large segments of the population – especially low-income and minority children – lack access to a computer at home. Does this impede educational achievement? We test this hypothesis by conducting the largest-ever field experiment...

Firms in Kenya rely on technologies such as computers, cell-phones, and generators to overcome constraints associated with regulations, infrastructure, security, workforce, corruption, and finance. This study shows that such reliance has significant positive impacts on productivity as measured...

Using North American data, we revisit the question first broached by Krueger (1993) and reexamined by DiNardo and Pischke (1997) of whether there exists a real wage differential associated with computer use. Employing a mixed effects model to correct for both worker and workplace unobserved...

The extent to which the impact of computer skills depends on how computers are used is investigated using British data from an establishment survey, cohort studies and the European E-Living survey. We examine the importance of activity and frequency of use in these various data sources. We find...

This paper examines the effect of the One Laptop Per Child program in Uruguay [Plan Ceibal] on household labor income. Since 2007, the Uruguayan government has delivered one laptop to every child and every teacher in public primary schools. This program has considerably increased access to...
