This finding is important for several active lines of research in macro/labor. For example, in the literature on the quantitative analysis of labor search models, it is the behavior of wages that distinguishes different calibration strategies with radically different implications. Current...

In this note we compare the laissez-faire steady-state solution in the Howitt and Aghion (1998) model to the social optimum. The analysis offers several new insights in comparison to the welfare analysis in Aghion and Howitt (1992). We find various new distortions between private and optimal...

We show that the key identifying assumptions underlying the existing approaches to identifying technology shocks in the data are violated in models with heterogeneous capital and labor. We propose a new method to identifying technology shocks in the data in presence of factor heterogeneity and...

This paper asks whether tax cycles or tax smoothing represents the optimal policy in models without any extrinsic uncertainty. To answer this question, I develop a general framework for studying tax cycles in a large class of models that feature various types of frictions. This framework adds...
