We study the importance of uncertainty and public finance to the welfare ranking of three environmental policy instruments: pollution taxes, pollution permits and Kyoto-like numerical rules for emissions. The setup is the basic stochastic neoclassical growth model augmented with the assumptions...

In this paper, we study a two-country dynamic setup with environmental externalities and potential model misspecification in relation to this public good. Under model uncertainty, robust policies help to correct the inefficiencies associated with free riding on public good provision, implying...

Using an intertemporal model of saving and capital accumulation with two types of agents (workers and capitalists) we demonstrate that it is impossible for any binding minimum wage to increase the after-tax incomes of workers if the production function is Cobb-Douglas with constant returns to...

This paper studies the aggregate and distributional implications of introducing tuition fees for public education services into a tax system with income and consumption taxes. The setup is a neoclassical growth model where agents differ in capital holdings. We show that the introduction of...

This short paper reconsiders the popular result that the lower the probability of getting reelected, the stronger the incumbent politicians incentive to follow short-sighted, inefficient policies. The set-up is a general equilibrium model of endogenous growth and optimal fiscal policy, in which...

This paper shows that whether pollution occurs as a by-product of economic activity (which is supposed to be the case in DCs), or as resource extraction (which is supposed to be the case in LDCs), matters for the dynamics of the optimal growth-environment-policy link. The context is a dynamic...

This paper analyzes long run outcomes resulting from adopting a binding minimum wage in a neoclassical model with perfectly competitive labour markets and capital accumulation. The model distinguishes between workers of heterogeneous ability and capitalists who do all the saving, and it entails...

We explain the public's support for the minimum wage (MW) institution despite economists' warnings that the MW is a "blunt instrument" for redistribution. To do so we build a model in which workers are heterogeneous in ability, and the government engages in redistribution through the public...

We study monetary policy under climate change in order to answer the question of whether monetary policy should take into account the expected impacts of climate change. The setup is a new Keynesian dynamic stochastic general equilibrium model of a closed economy in which a climate module that...

In this paper, foreign aid transfers can distort individual incentives, and hence hurt growth, by encouraging rent-seeking as opposed to productive activities. We construct a model of a small growing open economy that distinguishes two effects from foreign transfers: (i) a direct positive...
