The sign of the relationship between expected stock market returns and volatility appears to vary over time, a result that seems at odds with basic notions of risk and return. In this paper we construct an economy where production involves the use of both labor and capital as inputs. We show...

Recent research showing negative correlations between detrended output and prices during the postwar period has brought into question the conventional wisdom that prices are procyclical. However, this finding has been shown to be sensitive to the sample period considered. This paper examines the...

A typical (roughly) two-digit industry in the United States appears to have constant or slightly decreasing returns to scale. Three puzzles emerge, however. First, estimates tend to rise at higher levels of aggregation. Second, estimates of decreasing returns in many industries contradict...

This paper provides a general equilibrium multi-stage production model to explain the co-existence and co-movement of output- and input-inventories. The model offers a neoclassical perspective on the propagation mechanism of demand uncertainty. It reveals that uncertainty in demand at downstream...

Over the past twenty years, output growth in the U.S. has become noticeably less volatile. During that time, the economy has experienced two recessions, compared with four in each of the two preceding twenty year periods. Further, the loss in output during the last two recessions has been...

We argue that the behavior of manufacturing inventories provides evidence against models of business cycle fluctuations based on productivity shocks, increasing returns to scale, or favorable externalities, whereas it is consistent with models with short-run diminishing returns. Finished goods...

This paper provides a dynamic optimization model of durable good inventories to study the interactions between investment demand and production of capital goods. There are three major findings: First, capital suppliers' inventory behavior makes investment demand more volatile in equilibrium;...

This paper shows that the economic activity of the industrial North and developing South move together - when the North is above its trend, the South tends to be above its trend. We refer to this phenomenon as the "North-South business cycle." The paper develops a quantitative general...
