We study the effects of fiscal policy rules on the determinacy of rational expectations equilibrium in a perfectly competitive monetary model with constant returns. Government spending implies a distortion of the monetary steady state due to the implied taxation. We show that policy rules that...

This paper develops a simple endogenous growth model where pollution exposure and vulnerability are unequally spread across the population, and growth and distribution are endogenous. In this setup, we investigate whether tradeoffs between growth, distributional, and environmental concerns may...

In this paper, we develop a R&D-based growth model with a pollution externality and a health production sector. We study how health-impairing pollution affects long term growth, and the effect of an emissions' reduction policy (tax). We show that a tighter environmental tax has positive effects...

This paper analyses a small open economy Ramsey model with an endogenous labor supply and no capital. The number of firms is subject to adjustment costs, so that the entry dynamics is determined endogenously. We find that with imperfect competition, there is a first order effect of a demand...

This paper analyses an open economy Ramsey model with an endogenous labour supply without capital. The technology defines an optimal firm size. Changes to the number of firms is subject to adjustment costs, so that the entry dynamics is determined endogenously. We find that there is a short run...

We analyse how spatial disparities in innovation activities, coupled with migration costs, affect economic geography, growth and regional inequality. We provide conditions for existence and uniqueness of a spatial equilibrium, and for the endogenous emergence of industry clusters. Spatial...

The paper reports results on the effects of stylized stabilization policies on endogenously created fluctuations. A simple monetary model with intertemporally optimizing agents is considered. Fluctuations in output may occur due to fluctuations in labor supply which are again caused by volatile...

This paper analyzes the efficacy and desirability of decentralized fiscal policies, in a two-region federal economy, with monopolistic competition in local product markets, unionized local labor markets, and a nationwide competitive sector. Local governments are utilitarian and use...
