Experimental evidence has convincingly shown the existence of reciprocal inclinations, i.e., a tendency for people to respond in-kind to hostile or kind actions. Little is known, however, about: (i) the prevalence of reciprocity in the population, (ii) individual determinants of reciprocity,...

We exploit a natural experiment in which two professionals compete in a one-stage contest without strategic motives and where one contestant has a clear exogenous psychological momentum advantage over the other in order to estimate the causal effect of psychological momentum on performance. We...

We propose an urban land use model to discuss the conversion of customary agricultural land to formal and informal residential land in a developing country city. Because customary land sales are insecure, migrant buyers face a risk of eviction, which affects land markets in non-trivial ways....

The historical pattern of the demographic transition suggests that fertility declines follow mortality declines, followed by a rise in human capital accumulation and economic growth. The HIV/AIDS epidemic threatens to reverse this path. A recent paper by Young (2005), however, suggests that...

Economic reasons along with cultural affinities and the existence of networks have been the main determinants explaining migration flows between home and host countries. This paper reconsiders these approaches combined with the gravity model and empirically tests the hypothesis that ex-colonial...

This paper investigates cyclicality in women's labour supply motivated by the hypothesis that it contributes to smoothing household consumption in environments characterized by income volatility. We use comparable individual data on about 1.1 million women in 63 developing and transition...

This paper adopts a labor market economics perspective to understanding the crisis of health care professionals in Africa. Five challenges resulting from this crisis are identified: a production challenge, an underutilization challenge, a distributional challenge, a performance challenge, and a...

This essay investigates the determinants of the growth performance of Africa. I start by illustrating a broader research agenda which accounts not only for basic economic and demographic factors, but also for the role of history and institutional development. After reporting results from...

We are the first to provide a comparative empirical analysis of non-farm entrepreneurship in rural Africa, using the World Bank's unique LSMSISA dataset. This dataset covers six countries over the period 2005 to 2012. We find that rural enterprises tend to be small, informal household...

This paper explores the effects of remittance receipt on child labour in an African context. We focus on Burkina Faso, a country with a high prevalence of child labour and a high rate of migration. Given the complex relationship between remittance receipt and child labour, our identification...
