We analyse a model in which a government uses a second-best policy to affect the reallocation of labour, following a change in relative prices. We consider two extreme cases, in which the government has either unlimited or negligible ability to commit to future actions. We explain why the...

We study the dynamics of optimal trade policy in a model with costly inter-sectoral adjustment of labour, where migrants pay less than the marginal social cost of migration. If workers have rational expectations, a future tariff has an announcement effect on the current migration decision. If...

We model adjustment costs in a general equilibrium setting using a “transport sectorâ€. This sector provides services needed to re-allocate a factor of production across wo other sectors. A market imperfection in the transport sector causes adjustment to occur too slowly in the absence...

Intergenerational altruism and contemporaneous cooperation are both important to the provision of long-lived public goods. Equilibrium climate protection may depend more sensitively on either of these considerations, depending on the type of policy rule one examines. This conclusion is based on...

A small but growing body of literature uses overlapping generations (OLG) models to study environmental policy for long-lived problems such as climate change. An OLG model, unlike the infinitely lived representative agent model, distinguishes between impatience with respect to one¡¯s own...

A two-sector OLG model illuminates previously unexamined intergenerationaleffects of a tax that protects an environmental stock. A traded asset capitalizes the economic returns to future tax- induced environmental improvements, benefiting the current asset owners, the old generation. Absent a...

Markov perfection has become the usual solution concept to determine the non-cooperative equilibrium in a dynamic game. However, Markov perfection is a stronger solution concept than subgame perfection: Markov perfection rules out any cooperation in a repeated prisoners' dilemma game because the...

Este estudo tem como objetivo realizar uma análise empírica da estrutura dos custos de ajustamento do emprego industrial. Para tanto, estima-se um modelo dinâmico de demanda por trabalho que contempla custos de ajustamento quadráticos e custos de ajustamento fixos como casos particulares. A...
