This paper tests the hypothesis that a high and persistent exposure to infectious diseases increases the likelihood of civil conflicts. Diseases that are difficult to prevent and treat may reduce the opportunity costs of violent activities, both directly and indirectly. The analysis exploits new...

Economic development in Latin America has trailed most other world regions over the past four decades despite its relatively high initial development and school attainment levels. This puzzle can be resolved by considering the actual learning as expressed in tests of cognitive skills, on which...

We study the long-term determinants of the high rates of HIV infection in sub-Saharan Africa, particularly among women, with a focus on family structure and sexual behavior as shaped by the demographic shock following the transatlantic slave trade. First we show that, in clusters where polygyny...

Internal locus of control (LOC) is a highly beneficial non-cognitive skill, yet its long-term formation process remains poorly understood. Using British cohort data, we examine the role that fathers play in LOC maturation from childhood into middle age; a machine-learning algorithm is used to...

It has traditionally been argued that the development of telecommunications infrastructure is dependent on the quality of countries' political institutions. We estimate the effect of political institutions on the diffusion of three telecommunications services and find it to be much smaller in...

This paper analyses how governance or institutional quality and tax morale affect the shadow economy, using an international country panel and also within country data. The literature strongly emphasizes the quantitative importance of these factors to understand the level and changes of shadow...

This paper analyses how tax morale and countries' institutional quality affect the shadow economy, controlling in a multivariate analysis for a variety of potential factors. The literature strongly emphasizes the quantitative importance of these factors to understand the size and development of...

Why are socially beneficial reforms not implemented? One simple answer to this question (which has received little attention in the literature) is that this may be caused by generalized uncertainty about the effectiveness of reforms. If agents are unsure about whether a proposed reform will...

This study looks at the effect of welfare programs on work incentives and the adult labor supply in developing countries. The analysis builds on the experimental evaluations of three programs implemented in rural areas: Mexico's PROGRESA, Nicaragua's RPS and Honduras' PRAF. Comparable results...

Our objective is to analyse the role of teacher and school quality to explain differences in students' educational outcomes. With this aim, we use PISA microdata for 10 middle income and 2 high income countries and we apply decomposition methods in order to identify the role of these factors for...
