In many African societies, beliefs in `occult forces' play a crucial role in mobilizing powerful social energies. Anthropologists, and more recently economists, have also stressed the importance of magico-religious practices in supporting redistributive norms and the important role played by...

Common wisdom as well as sound analytical arguments suggest that stronger punishment of deviant behavior meted out by a principal typically prompts the agents to better conform with his objectives. Addressing the specific issue of donor-beneficiary relationships in the context of participatory...

If we understand well the individualization of land tenure rules under conditions of growing land scarcity and increased market integration, much less is known about the mode of evolution of the farm-cum-family units possessing the land. Inspired by first-hand evidence from West Africa, this...

This paper describes Robinson's (1988) double residual semiparametric regression estimator and Hardle and Mammen's (1993) specification test implementation in Stata. Some simple simulations illustrate how this newly coded estimator outperforms the already available semiparametric plreg command.

This paper presents a dynamic factor model where the extracted factors and shocks are given a clear economic interpretation. The economic interpretation of the factors is obtained by means of a set of over-identifying loading restrictions, while the structural shocks are estimated following...

This paper develops a Spatial Vector Auto-Regressive (SpVAR) model that takes into account both the time and the spatial dimensions of economic shocks. We apply this framework to analyze the propagation through space and time of macroeconomic (inflation, output gap and interest rate) shocks in...

Recent evidence suggests that aid induces migration. However, total migration is quite general from a policy perspective since what explains the welfare consequences of migration is the extent of emigration selection. In this paper we ask whether skilled or unskilled migration is more sensitive...

This paper employs a production frontier approach that allows distinguishing technologic progress from efficiency development. Data on 35 African countries in 1970-2007 show that efficiency losses have constrained growth in Africa while technology progress has played a marginal growth enhancing...
