In developing countries, labour supply and activity choices are distorted by the existence of labour market imperfections restricting the entry in the activity sectors or rationing the worked hours. The presence of decreasing returns to labour in the informal sector is another specific...

In rural areas of LDC, because of the existence of market imperfections, health and nutrition status may depend on the levels of specific agricultural productions and not only on the income level. However, these specific impacts have never been studied. We estimate, from a sequential...

Using panel data from Rwanda, we estimate seasonal transient and chronic poverty indices, for different poverty line, poverty indicators, equivalence scale, and with and without the corrections for price variability and for the sampling scheme. We also estimate sampling standard errors for the...

Under perfect observation of incomes, designing such scheme boils down to solving an optimisation program under constraints, which can be achieved with well-defined methods. In contrast, when incomes cannot be perfectly observed, the schemes are usually based on predictions of living standards...

In this paper we study how the Huber estimator can be adapted to the presence of endogeneity in a two stage equations setting similar to that of 2SLS. We propose an estimation procedure that is at the same time relatively (i) simple, (ii) robust and (iii) efficient. Moreover, we deal with the...

This paper introduces a new methodology to target direct transfers against poverty. Our method is based on observable correlates and on estimation methods that focus on the poor. Using data from Tunisia, we estimate ‘focused’ transfer schemes that improve anti-poverty targeting performances....

Spatial price dispersion varies because of climatic fluctuations, marketimperfections, economic growth or economic policies. These variations areoften neglected in poverty studies.In this paper, we propose a simple simulation formula to assess the effecton poverty of a change in the spatial mean...

In this paper, we study the return to human capital variables for wages of workers observed in Tunisian matched worker-firm data in 1999. This tells us how returns to human capital in a Less Developed Country like Tunisia differ from the industrial countries usually studied with matched data. We...
