Poverty analysis often results in the computation of poverty indexes based on so-called poverty lines which can be region specific poverty lines. The poverty lines are made of two components, namely the amount of income to satisfy the food and the non food needs. For both components, one needs...

This paper presents a methodological extension of Deaton's (1990) model for estimating price elasticities, by pooling Tunisian data from several surveys to improve the inter-cluster variability of unit values which is one of the key elements used in the derivation of these elasticities. Since...

This paper develops a theory of sharecropping which emphasizes the dual role of moral hazard in the provision of effort and financial constraints. The model is compatible with a large variety of contracts as observed in the region of El Oulja in Tunisia. Using an original data set including...

In the perspective of globalization, the Middle East and North Africa countries must revise soundly their irrigation strategies, pay more attention to virtual water trade and resolve problems of transboundary water resource management, if they want to maintain an irrigation sector able to secure...

This paper investigates the patterns of agricultural productivity growth in Middle East and North Africa (MENA) countries during the period 1970–2000. We use a nonparametric, output-based Malmquist index to examine whether our estimates confirm or invalidate the results of previous studies...

Poverty analysis conducted in Tunisia so far depends heavily upon the choice of poverty lines. The latter are usually constructed by considering a fraction of median incomes. This yields large differentials between urban and rural lines up to a factor 2 leading to the conclusion that the...

Although poverty is widely recognised as a multidimensional phenomenon, we still believe that monetary aspect has a fundamental role and therefore deserves a special treatment. For this reason we propose an individual unidimensional measure according to a fuzzy approach that, unlike conventional...
