Theoretical studies have shown that under unorthodox assumptions on preferences and production technologies, collateral constraints can act as a powerful amplification and propagation mechanism of exogenous shocks. We investigate whether or not this result hold under more standard assumptions....

This paper studies the role of collateral constraints in transforming small monetary shocks into large persistent output fluctuations. We do this by introducing money in the heterogeneous-agent real economy of Kiyotaki and Moore (1997). Money enters in a cash-in-advance constraint and is...

We develop a business cycle model in which consumption goods, physical capital, and human capital are produced in separate sectors. An important feature of the model is that human and machine inputs in the production process are treated symmetrically: each has both a stock and flow component....

Who was closer to the source of business cycle fluctuations--Keynes or Prescott and Solow? Two types of business-cycle impulses which have been associated with their names -- marginal efficiency of investment shocks (Keynes) and technology shocks (Prescott and Solow) -- are studied here in a...
