We explore the existence of endogenous fluctuations with a rational bubble and the stabilizing role of fiscal and monetary policies. Consumers' credit constraints, the role of collateral and a portfolio choice are the key ingredients of our analysis. We consider an overlapping generations model...

The standard economic view of the personal income tax is that it is a distortionary way of raising revenue which nonetheless has value because it tends to increase equality. However, when wages deviate from marginal product, the laissez-faire equilibrium is inefficient, and there can be an...

The aim of this paper is to study the role of progressive tax rules on the allocations of steady state and the stability properties in a Ramsey economy with heterogeneous households and borrowing constraints. Since labor supply in elastic, considering different tax rates on capital and labor...

Policymakers have good reasons to prefer capital-based policies - such as CAFE standards or feebates programs - over a carbon price. A carbon price minimizes the discounted cost of a climate policy, but may result in existing capital being under-utilized or scrapped before its scheduled...

We propose an ethical viewpoint based on the possibility of the realization of the worst-case scenario in order to reduce future generations risks in terms of discounting. Applied to the question of conservation of a renewable resource, we show that an economy, where the social planner takes...

This paper analyzes the double dividend and distributional issues within an overlapping generations models framework with involuntary unemployment. We characterize the necessary conditions for the obtention of a double dividend when the revenue of the environmental tax is recycled by a variation...

There are two main approaches for defining social welfare relations for an economy with infinite horizon. The first one is to consider the set of intertemporal utility streams generated by a general set of bounded consumptions and define a preference relation between them. This relation is...

We defend a methodology of discounting, for the evaluation of the long-term effects of climate policies, which relies on a social welfare objective, against the view that the market rate of return should be used for that purpose. We also show that in the long run, the discount rate for such...

Early regulator interventions into problem banks is one of the key suggestions of Basel II. However, no guidance is given on their design. To fill this gap, we outline an incentive-based preventive supervision strategy that eliminates bad asset management in banks. Two supervision techniques are...

This paper applies the Mean Fi eld Game approach pioneered by Lasry and Lions (2007) to the analysis of the researchers' academic productivity. It provides a theoretical motivation for the stability of the universaly observed Lotka's law. It shows that a remuneration scheme taking into account...
