This paper explores asset pricing in economies where there is no direct insurance against idiosyncratic risks but other assets can be used for self-insurance, subject to exogenously-imposed borrowing limits. We analyze an endowment economy, based on Huggett (1993) [11], both with and without...

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 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...

This paper analyzes the effects of entry regulations and firing costs on cross-country differences in income and productivity. We construct a general equilibrium industry- dynamics model and quantitatively evaluate it using the cross-country data on entry costs and firing costs. Entry costs...

This paper analyzes the welfare effects of unanticipated policy changes in a model with complete asset markets and heterogeneous agents. There are two effects: an effect of the change in wealth and a direct effect from the price change.

This paper reconsiders the cost of business cycles under market incompleteness. Primarily, we focus on the heterogeneity in the cost among different skill groups. Unskilled workers are subject to a much larger risk of unemployment during recessions than are skilled workers. Moreover, unskilled...

This paper constructs a general equilibrium search-matching model with heterogeneous workers. Workers choose whether to invest in general human capital or specific human capital when they enter the labor market. We analyze how unemployment benefits affect the choice of the type of human capital...

This paper formulates Rosenberg's (1982) "learning by using" as a stochastic process. The producer of machines learns from the experience of users. Due to this learning, the quality of machines improves over time. It turns out that the process of this improvement approximately takes an...

This paper analyzes the job-to-job transitions of workers in the United States. I propose a new method of correcting the time-aggregation bias. The bias-corrected series from 1996 to 2011 reveals a procyclical pattern of job-to-job transition and a large decline since the beginning of the 2000s....
