This paper investigates spatial variations in product prices using an exhaustive micro dataset on fish transactions. The data record all transactions between vessels and wholesalers that occur on local fish markets in France during the year 2007. Spatial disparities in fish prices are sizable,...

This paper explores the implications for trade relations of the greening of world politics. It modifies the standard theory of changing comparative advantages in a growing world economy to show the effects on trade of taking into account the fact that the demand for domestic environmental...

In this Paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse. We show: (1) politicians tend to over-extract natural resources relative to the efficient extraction path because they discount the future too...

International trade and environmental regulation are interdependent. Central and East European Countries (CEECs) are now being integrated in international markets, and the question arises how environmental issues should be taken account of during this process and which institutional framework is...

We consider the decision of an agent with time inconsistent preferences to undertake an irreversible investment that yields an uncertain current benefit and a delayed cost. We show that, if the flow of information revealed between periods when the investment is postponed is sufficiently high,...

We analyze the decision of individuals with time inconsistent preferences who undertake irreversible activities yielding either a current cost and a future benefit or a current benefit and a future cost. We first show that, when benefits come earlier than costs, the individual faces a...

This paper employs cohort technique and Consumer Expenditure Survey data to construct average age-profiles of consumption and income over the working lives of typical households across different education and occupation groups. Using these profiles, we estimate a structural model of optimal...

This paper develops a theory of regular Markov perfect equilibria in dynamic stochastic games. We show that almost all dynamic stochastic games have a finite number of locally isolated Markov perfect equilibria that are all regular. These equilibria are essential and strongly stable. Moreover,...

We develop a continuous-time dynamic model with switching costs. In a relatively simple Markov Perfect equilibrium, the dominant firm concedes market share by charging higher prices than the smaller firm. In the short-run, switching costs might have two types of anti-competitive effects: first,...

Inflation-targeting central banks have only imperfect knowledge about the effect of policy decisions on inflation. An important source of uncertainty is the relationship between inflation and unemployment. This Paper studies the optimal monetary policy in the presence of uncertainty about the...
