We revisit the link between poverty, the middle class and institutional outcomes using a newly developed cross-country panel dataset containing detailed information on the distribution of income and expenditures. When the size of the middle class increases (measured as the proportion of people...

Middle class values have long been perceived as drivers of social cohesion and growth. In this paper we investigate the relation between class (measured by the position in the income distribution), values, and political orientations using comparable values surveys for six Latin American...

This paper presents evidence on the making of the middle class in Africa by exploiting a comparable micro data from the Demographic and Health Surveys (DHS) for thirty-seven countries over two decades consisting of over seven hundred thousand household histories. We constructed a pseudo-panel to...

This study investigates the causal impacts of integrating mobile phone technologies into traditional public labor-market intermediation services on employment outcomes. By providing faster, cheaper and up-to-date information on job vacancies via SMS, mobile phone technologies might affect the...

This study uses a nationally representative survey to analyze a key survey design decision in child labor measurement: self-reporting versus proxy interviewing. The child/proxy disagreement affects 20 percent of the sample, which translates into a 17.1 percentage point difference in the national...

Teachers differ greatly in how much they teach their students, but little is known about which teacher attributes account for this. We estimate the causal effect of teacher subject knowledge on student achievement using within-teacher within-student variation, exploiting a unique Peruvian...

We investigate the returns to capital and capital accumulation using panel data of Peruvian micro enterprises (MEs). Marginal returns to capital are found to be very high at low levels of capital, but rapidly decreasing at higher levels. The dynamic analyses of capital accumulation in MEs...
