The standard one-sector real business cycle model is unable to generate expectations-driven business cycles. The current paper shows that this conundrum can be solved by adding countercyclical markups and modest capital adjustment costs.

Two dynamic general equilibrium economies compete in explaining the United States' interwar business cycles. Despite the demand driven contender's slight advantages, the results remain too close to call a clear winner.

We examine a general equilibrium model with collateral constraints and increasing returns to scale in production. The utility function is nonseparable, with no income effect on the consumer's choice of leisure. Unlike this model without a collateral constraint, we find that indeterminacy of...

We show that a one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news shocks to future consumption demand. In sharp contrast to many...

The standard one-sector real business cycle model is unable to generate expectations-driven fluctuations. The addition of countercyclical markups and modest investment adjustment costs offers an easy fix to this conundrum. The simulated model generates quantitatively realistic business cycles...

This paper presents a one-sector optimal growth model with variable capacity services and production externalities. It uses a new formulation of the endogenous capital utilization rate in which utilization costs appear in the form of variable maintenance expenses. I find that indeterminacy...

The paper finds empirical evidence on the ripple effect of sunspots on the interwar German economy. It identifies a sequence of negative shocks to expectations for the 1927 to 1932 period. The artificial economy predicts the 1928-1932 depression and a long boom from 1933 onwards. Overall, a...

This paper examines the effect of the elasticity of technological substitution on the existence of equilibrium indeterminacy in two-sector economies. Recent empirical evidence, the elasticity of substitution between capital and labor is below unity. We ?nd that this requires a higher degree of...

In this paper, we address the causes of the Roaring Twenties in the United States. In particular, we use a version of the real business cycle model to test the hypothesis that an extraordinary pace of productivity growth was the driving factor. Our motivation comes from the abundance of evidence...

High degrees of relative risk aversion induce indeterminacy in cash-in-advance economies. This paper finds that Taylor-style policies can pre-empt such sunspot equilibria. Specific policy recommendations depend on the fundamentals of the economy, i.e. the empirically true value of coecient of...
