Using data on house sales and inventories of unsold houses, this paper shows that changes in sales volume are largely explained by changes in the frequency at which houses are put up for sale rather than changes in the length of time taken to sell them. Thus the decision to move house is key to...

The theory of monotone comparative statics and supermodular games is presented as the appropriate tool to model complementarities. The approach, which has not yet been fully incorporated into the standard toolbox of researchers, makes the analysis intuitive and simple, helps in deriving new...

Fear of risk provides a rationale for protracted economic downturns. We develop a real business cycle model where investors with decreasing relative risk aversion choose between a risky and a safe technology that exhibit decreasing returns. Because of a feedback effect from the interest rate to...

Firms expect certain investment expenditures. Firms realize certain investment expenditures. The difference is an investment surprise. With the help of the IFO Investment Survey for the German manufacturing sector we measure firms’ (quantitative) investment expectations and firms’...

In this article, we demonstrate that a small degree of stochastic variation in the depreciation rate of capital can greatly reduce the comovement between hours worked and labour productivity in a neoclassical growth model. The depreciation rate is modeled as a Markov process to place a strict...

This paper develops a new analysis of the U. S. economy in the 1920s that is illuminated by contrasts with the 1990s, and it also re examines the causes of the Great Depression. In both the 1920s and the 1990s the acceleration of productivity growth linked to the delayed effects of previously...

Changes in firms’ investment expenditures are considered one of the primary channels through which energy price shocks are transmitted to the economy. It is widely believed that the response of business fixed investment to energy price increases differs from its response to energy price...

This paper adds a highly-leveraged financial sector to the Ramsey model of economic growth and shows that this causes the economy to behave in a highly volatile manner: doing this strongly augments the macroeconomic effects of aggregate productivity shocks. Our model is built on the financial...

This paper explores the dynamic behavior of investment and hiring within a unified framework, stressing their mutual dependence and placing the emphasis on their joint, forward-looking behavior. Using structural estimation in aggregate, private sector U.S. data, it shows that the model, which...

Economic decisions such as occupational and entrepreneurial choices may violate true comparative advantage when economic agents are uncertain about which activity best matches their talents. If relative performance varies over the business cycle (for instance, if downturns affect...
