We examine how changes in tax policies affect the dynamics of the distributions of wealth and income in a Ramsey model in which agents differ in their initial capital endowment. The endogeneity of the labor supply plays a crucial role in determining inequality, as tax changes that affect hours...

We derive a mesoscopic description of the behavior of a simple financial market where the agents can create their own portfolio between two investments alternatives: a stock and a bond. The model is derived starting from the Levy-Levy-Solomon microscopic model using the methods of kinetic theory...

This paper proposes a unified framework for the analysis of inequalities. In contrast to the former literature on inequalities, housing is included as a major determinant of individual saving behavior. Disparities across locations affect individual outcomes in both labor and education markets....

This paper puts forward an explanation of the rapid increase in golden handshake provision in Europe over the last ten years, based on both enhanced investor protection and attractive tax codes for severance pay. This article takes up a framework in which asymmetric information about the quality...

There is a capital taxation puzzle in most developed countries. Since the 1960s, revenues from wealth transfer taxation have been especially low and decreasing as a percentage of GDP, even to the extent of disappearing in quite a number of cases; by contrast, lifetime wealth or capital taxation...

During the last twenty years, microsimulation models have been increasingly applied in qualitative and quantitative analysis of public policies. This paper provides a discussion on microsimulation techniques and their theoretical background as a tool for the analysis of public policies with...

This paper examines how a government should intervene when agents make, for different reasons, choices that have long term detrimental effects on their survival prospects. We consider an economy where some agents make risky choices (here sin good consumption) out of myopia, and regret their...

This paper studies the design of the optimal non linear taxation in an economy where longevity varies across agents, and depends on three factors: longevity genes, health investment and farsightedness. Provided earnings, farsightedness and genes are correlated, governmental intervention can be...

This paper analyzes optimum income taxation in a model with endogenous job destruction that gives rise to unemployment. It is shown that optimal tax schemes comprise both payroll and layoff taxes when the state provides public unemployment insurance and aims at redistributing income. The optimal...

This paper studies how oil owners can benefit from carbon taxation. We build a Hotelling-like model with three energy resources: oil (exhaustible, polluting), coal (non exhaustible, very polluting) and solar energy (non exhaustible, non polluting). The CO2 concentration must be kept under a...
