This paper studies fluctuations in a real business cycle model when there is a risk neutral agent present to offer insurance to workers. This economy is compared with one in which there is no risk neutral agent but labor is indivisible. In static models it is difficult to distinguish the risk...

The reason why the assumption of a representative agent is so popular in the equilibrium business cycle literature is mainly that equilibrium allocations are derived by solving a concave programming problem, whereas once heterogeneity is introduced it is necessary to solve for weights on...

The key ingredients of real business cycle models are common. The market structure is perfectly competitive, the forcing process is a technology shock, and in most cases agents are identical. Textbook market structures are introduced in a real business cycle model. The market structures studied...

A modified version of the nominal contract developed by Gray (1976) and Fischer (1977) is introduced in a general equilibrium model with money which has been used in the real business cycle literature. Money is introduced in the model through cash-in-advance constraint. The contract studied is...

This paper develops and estimates a dynamic general equilibrium model that realistically accounts for an input-output linkage between firms operating at different stages of processing. Firms face technological change which is specific to their processing stage and charge new prices according to...

Barro and King (1984) conjecture that shocks other than those to total factor productivity will have difficulty generating key business cycle comovements between output, consumption, investment and hours worked. Recent years have seen the emergence of a class of DSGE models in which aggregate...

Indeterminacy in new Keynesian models with Calvo-contracts can occur even at low trend inflation levels of 2 or 3%. The interaction of trend inflation with nominal wage rigidity and trend growth in output causes large distortions in the steady state and expands the indeterminacy region....
