This paper analyzes a business cycle model with labor market frictions as well as an extensive labor supply margin. There are exogenous aggregate shocks to productivity, the job finding rate, and the separation rate. Workers also face idiosyncratic productivity (wage) shocks that they cannot...

We consider a decentralized equilibrium of a 1-region, global neoclassical growth model with non-renewable exhaustible resources and optimizing agents. The resource generates energy, which is essential for producing final output. Its use generates externalities by affecting the climate. The...

We build a model that incorporates both labor supply and frictions and use it to assess the effects of various tax and transfer programs on aggregate employment and unemployment. In particular, we assess the debate between Prescott and Ljungqvist and Sargent about the relative importance of...

Rogerson (1988).

We combine two setups: Bewley-Huggett-Aiyagari and Mortensen-Pissarides. Wages are given by wage bargaining, and wages will depend positively on wealth since rich workers have a better outside option. We also study the model with aggregate risk.

We investigate the welfare effects of eliminating business cycles in a model with substantial consumer heterogeneity. The heterogeneity arises from uninsurable idiosyncratic uncertainty in preferences and employment status. We distinguish between short- and long-term unemployment. Long-term...

How does the size of the transfer system evolve in the short and in the long run? We construct a model where taxation is distortionary because it discourages capital accumulation. We compare the Ramsey allocation with the time-consistent allocation. The latter can be interpreted as the outcome...

We explore a political-economy model of labor subsidies, extending Meltzer and Richard's median-voter model to a dynamic setting. We explore only one source of heterogeneity: initial wealth. As a consequence, given an operative wealth effect, poorer agents work harder, and if the agent with...

This paper offers several appendices for the article: the integration principle applied to the baseline model, the computational algorithm for the baseline model, calculating the welfare gain, algorithm for the model with short- and long-term unemployment, as well as additional result tables.

In this paper we document that "frictional wage inequality" (i.e. due to pure luck in the matching process in the labor market) is large and that both the standard McCall search model and the simplest Diamond-Mortensen-Pissarides matching model, reasonably calibrated, are strikingly unable to...
