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 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...

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

We introduce an analytical framework for welfare analysis that accounts for changes in the joint distribution of prices and incomes by using parametric formulae of poverty and inequality measures. We propose statistical indicators for the levels, variabilities and a statistical link of price...

We draw some lessons from the Tunisian experience of social reforms and associated unrest. Our main interest is the riots that occurred after subsidy cuts and the attempts at substitution of price subsidies by direct cash transfers. We propose new welfare indicators to assess reforms in such...

It is not known to what extent welfare measures result from seasonal and geographical price differences rather than from differences in living standards across households. Using data from Rwanda in 1983, we show that the change in mean living standard indicators caused by local and seasonal...
