The Ramsey tax problem examines the design of linear commodity taxes to collect a given tax revenue. This approach has been seriously challenged by Atkinson and Stiglitz (1976) who show that (under some conditions) an optimal income tax makes commodity taxes redundant. In the meantime, the...

This paper provides a unified treatment of externalities associated with fertility and human capital accumulation as they relate to pension systems. It considers as overlapping generations model in which every generation consists of high earners and low earners with the proportion of types being...

When accidental bequests signal otherwise unobservable individual characteristics such as productivity and longevity, the tax administration should partition the population into two groups: One consisting of people who do not receive an inheritance and the other of those who do. The first tagged...

We study the role and design of private and public insurance programs when informal care is uncertain. Children’s degree of altruism is randomly distributed over some interval. Social insurance helps parents who receive a low level of care, but it comes at the cost of crowding out informal...

We study the joint design of nonlinear income and education taxes when the government pursues redistributive objectives. A key feature of our setup is that the ability type of an agent can affect both the costs and benefits of acquiring education. Market remuneration of agents depends on both...

This paper introduces money into an overlapping generations model with endogenous growth. The model, due to Docquier et al. (2007), exhibits a positive intergenerational externality which precludes its laissez-fair equilibrium to be optimal even if the government can control the level of...

This paper develops an overlapping-generations model with heterogeneous agents in terms of earning ability and cash-in-advance constraint. It shows that tax policy cannot fully replicate or neutralize the redistributive implications of monetary policy. While who gets the extra money becomes...

We study the joint design of nonlinear income and education taxes when the government pursues redistributive objectives. A key feature of our setup is that the ability type of an agent can affect both the costs and benefits of acquiring education. Market remuneration of agents depends on both...

We study the optimal long-term care policy when informal care can be provided by children in exchange for monetary transfers by their elderly parents. We consider a bargaining model with single-child families. Daughters have a lower labor market wage and a lower bargaining power within the...

We present a simple dynamic model based on on-the-job human capital accumulation affecting the dynamic of wage rates and labor earnings. We show how these dynamics are determined by the interplay between the supply and demand sides of the labor market. The model can generate and explain the...
