We show that the joint behavior of stock prices and TFP favors a view of business cycles driven largely by a shock that does not affect productivity in the short run ? and therefore does not look like a standard technology shock ? but affects productivity with substantial delay ? and therefore...

Business cycles reflect changes over time in the amount of trade between individuals. In this paper we show that incorporating explicitly intra-temporal gains from trade between individuals into a macroeconomic model can provide new insight into the potential mechanisms driving economic...

This paper reexamines the question of how to explain business cycle co-movements within and between countries. First, we present a simple flexible price models to illustrate how and why news shocks can generate robust positive co-movements in economic activity across countries. We also discuss...

Recessions often happen after periods of rapid accumulation of houses, consumer durables and business capital. This observation has led some economists, most notably Friedrich Hayek, to conclude that recessions mainly reflect periods of needed liquidation resulting from past over-investment....

We document the cyclical behavior of several measures of the relative price of investment goods for the U.S. economy over the last fifty years. Our main result is that there is no robust evidence that this relative price is countercyclical in the data. Furthermore, for the recent (post-Volcker)...

There is a widespread belief that changes in expectations may be an important independent driver of economic fluctuations. The news view of business cycles offers a formalization of this perspective. In this paper we discuss mechanisms by which changes in agents' information, due to the arrival...
