This article discusses the interactions among pension reform, labor market and inter-generational distribution issues through an overlapping general equilibrium approach with imperfect labor markets. Workers with different ages are imperfectly substitutable and wages do not clear labor markets. Increasing contribution rates has a strong negative effect on welfare and unemployment, particularly, for the youth. Contrary to the popular wisdom, postponing the retirement age does not entail an increase in youth unemployment. The change in incentives induces a substitution of old-age workers by young workers who constitute the cheapest labor category. However, this scenario substantially increases the implicit tax for older workers as well as for the youngest. Finally, the middle-aged are those that benefit the most from welfare increasing reforms. [ABSTRACT FROM AUTHOR]

The aim of this paper is to study the macroeconomic effects of a few scenarios reforms of the pension system Tunisian who correspond respectively to the increase of the contribution rate, to the reduction of the replacement rate, and finally to the introduction of a dose of funded in our pension system. In other word, we will examine the evolution of consumption, saving, capital accumulation through a general equilibrium model of overlapping generation similar to DEGER (2011). [ABSTRACT FROM AUTHOR]
