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 build a general equilibrium model that features uninsurable idiosyncratic shocks, search frictions and an operative labor supply choice along the extensive margin. The model is calibrated to match the average levels of gross flows across the three labor market states: employment,...

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...

We develop a simple model featuring search frictions and a nondegenerate labor supply decision along the extensive margin. The model is a standard version of the neoclassical growth model with indivisible labor and idiosyncratic productivity shocks and frictions characterized by employment loss...

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 analyse a Bewley-Huggett-Aiyagari incomplete-markets model with labour-market frictions. Consumers are subject to idiosyncratic employment shocks against which they cannot insure directly. The labour market has a Diamond-Mortensen-Pissarides structure: firms enter by posting vacancies and...
