This paper contributes to the on-going empirical debate regarding the role of the RBC model and in particular of technology shocks in explaining aggregate fluctuations. To this end we estimate the model's posterior density using Markov-Chain Monte-Carlo (MCMC) methods. Within this framework we...

The stylized facts suggest a negative relationship between tax progressivity and the skill premium from the early 1960s until the early 1990s, and a positive one thereafter. They also generally imply rising tax progressivity, except for the 1980s. In this paper, we ask whether optimal tax policy...

This paper uses a model of trade in vertically differentiated products to examine the effects of excessive wage increases (i.e. above productivity) on the volume of commodity imports. The model predicts that for commodities, in which the country has comparative advantage in high quality...

A persistent criticism of general equilibrium models of monetary policy which incorporate nominal inertia in the form of the New Keynesian Phillips Curve (NKPC) is that they fail to capture the extent of inflation inertia in the data. In this paper we derive a general equilibrium model based on...

In this paper we study the link between elections, fiscal policy and aggregate fluctuations. The set-up is a stylized dynamic stochastic general equilibrium model incorporating both technology and political re-election shocks. The later are incorporated via a two-party model with elections. The...

We develop an endogenous growth model to quantify how permanent structural policy changes that enhance the fiscal policy mix, markets' functioning, and public institutions' quality affect long-term growth and welfare. The reforms include increased public investment, reduced market power through...
