One considers a model of accumulation of the human capital in the presence of the international migration offers. One shows that under certain conditions,this option can support the increase in the stock of the national human capital by taking of account the externalities. Thus the `brain drain'...

We develop a model of intergeneratioal coresidence and transfers within the family in a setting of asymmetric information. Following an exchange motive altruistic parents receive services from their children, who may make them financial gifts in return. However, parents do not know the privacyc...

Under Principal-Agent-Supervisor paradigm, we examine in this paper how a tax collection agency changes optimal schemes in order to lessen the occurrence of corruption between the tax collector and the taxpayer. The Principal, who maximizes the expected net fiscal revenue, reacts by decreasing...

In this paper, we introduce firm heterogeneity in the context of a model of non-compliance with minimum wage legislation. The introduction of heterogeneity in the ease with which firms can be monitored for non compliance allows us to show that non-compliance will persist in sectors which are...

Remittances by migrants to their countries of origin constitute the largest source of external finance for developing countries after foreign direct investment . To shed light on this important fact, in this paper we consider a model of micro-foundations of the links between remittances finance...

Examining the structure of long-term unemployment first reveals a number of effects, Le. the cohort effect, the seniority effect, the structure due to seniority effect. An empirical application is developed from data compiled by INSEE. An unemployment recurrence index is then constructed. The...

We consider a model that extends the scope of social preferences of the families of the migrants. This extension allows us to show that if some poor families receive remittances and social culture affects the composition of their consumption, then in presence of strong social inequality, poor...

In this paper we consider a model of optimal efficiency and agglomeration economies .Given the presence of urban and social externalities and in the absence of corrective policy, the efficiency wage chosen in decentralized market economy is too high. Indeed, in her optimal choice of wage and...

We integrate a general social norm function which associates status to accumulation of capital and consumption into a very simple model of endogenous growth. We show that societies which place a greater cultural weight on capital as opposed to consumption preferences will experience fast growth....

In this paper, we consider a two-period model of migration and remittances as implicit contract in a context of asymmetric information. Our model offers new theoretical findings with respect to the previous literature on the main determinants of remittances. According to self-interest thesis,...
