In empirical studies it often happens that some variables for some units are far away from the other observations in the sample. These extreme observations, or outliers, often have a large impact on the results of statistical analyses - conclusions based on a sample with and without these units...

This paper makes three contributions. (1) It summarizes in tabular form a recent literature made of 36 micro-econometric studies for 16 different countries on the relationship between export destination and firm performance. (2) It reports estimates of the productivity premium of German firms...

From the literature on decentralization, it appears that the fiscal vertical imbalance is somehow inherent to multi-level governments. Using a stylized model we show that this leads to a reduction in the extent of redistributive fiscal policies if the maximal tolerable size of government has...

In this article we use the high-quality data coming from the Luxembourg Income Study Project, in a panel framework, to test for the effects of electoral systems on both poverty and income inequality. We find that when de degree of proportionality of an electoral system increases, inequality and...

This paper is an attempt to understand the factors behind low contract renewal rates frequently observed in insurance programs in poor countries. This is done on the basis of the experience of a microinsurance health program in India. We show that deficient information about the insurance...

We build a simple model of legal dualism in which a pro-poor legal reform, under certain conditions, causes the conflicting custom to go some way toward producing the change intended by the legislator. It then acts as an 'outside anchor' that exerts a 'magnet effect' on the custom. We illustrate...

Customary rules governing access to land and other natural resources in village societies have characteristics that allow them to fulfil social security functions and achieve equity objectives. This is true of both common-property resources and land parcels held under individualized tenure....

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...
