Effects of economic and social incentives on bureaucratic quality: Experimental Evidence from Sierra Leone
Using a field experiment implemented in Sierra Leone we examine the joint effects of local selection, local monitoring, and incentivized payment mechanisms. We find evidence consistent with past literature that social pressure improves quality. These gains however are no better than gains from simple direct payment mechanisms that involve similar direct but lower social costs. There is weak evidence of crowding out effects. We find no effects of varying selection mechanisms. Analysis of a structural model identifies conditions under which social or economic incentives are more or less likely to be effective.

Industrialization, returns, inequality (Co-authors: Thilo Albers and Timo Stieglitz)
écrit avec Thilo Albers and Timo Stieglitz
How does revolutionary technological change impact wealth inequality? We turn to the mother of all technological shocks–the Industrial Revolution–and analyze its role for wealth concentration both empirically and theoretically. Based on a novel dataset on wealth shares at the level of Prussian counties, we provide causal evidence on the positive effect of industrialization on the top percentile's wealth share and the inequality among top fortunes. We show that this relationship between industrialization, wealth concentration, and tail fattening is consistent with both cross-country data on national wealth distributions and with a new individual-level dataset of Prussian millionaires. We disentangle the mechanisms underlyi ng the observed wealth concentration and tail fattening by introducing a dynamic two-sector structure into an overlapping generations model with heterogeneous returns to capital. In particular, we study the role of sector-specific scale dependence, i.e., the positive correlation of rates of return and wealth in industry, and dynastic type dependence in returns, i.e., the gradual one-directional transition of wealth-holders from the low-return traditional to the high-return industrial sector. The simulations suggest that the combination of these two features explains about half of the total increase of the top-1% share, while the other half resulted from the general increase and higher dispersion of returns induced by the emerging industrial sector.
