Interpreting the Great Moderation: changes in the volatility of economic activity at the macro and micro Levels
We review evidence on the Great Moderation together with evidence about volatility trends at the micro level to develop a potential explanation for the decline in aggregate volatility since the 1980s and its consequences. The key elements are declines in firm-level volatility and aggregate volatility - most dramatically in the durable goods sector - but with no decline in household consumption volatility and individual earnings uncertainty. Our explanation for the aggregate volatility decline stresses improved supply-chain management, particularly in the durable goods sector, and, less ...

What inventory behavior tells us about business cycles
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 inventories move proportionally much less than sales or production over the business cycle, which we show implies procyclical marginal cost and countercyclical price markups. Obvious measures for marginal cost do not show high marginal cost near peaks, as required to rationalize the inventory behavior, ...

What inventory behavior tells us about business cycles
Manufacturers' finished goods inventories are less cyclical than shipments. This requires marginal cost to be more procyclical than is conventionally measured. In this paper, alternative marginal cost measures for six manufacturing industries are constructed. These measures, which attribute high-frequency productivity shocks to procyclical work effort, are more successful in accounting for inventory behavior. Evidence is also provided that the short-run slope of marginal cost arising from convexity of the production function is close to zero for five of the six industries. The paper concludes ...

Tracking the new economy: using growth theory to detect changes in trend productivity
The acceleration of productivity since 1995 has prompted a debate over whether the economy's underlying growth rate will remain high. In this paper, we propose a methodology for estimating trend growth that draws on growth theory to identify variables other than productivity namely consumption and labor compensation to help estimate trend productivity growth. We treat that trend as a common factor with two "regimes," high-growth and low-growth. Our analysis picks up striking evidence of a switch in the mid-1990s to a higher long-term growth regime, as well as a switch in the early 1970s in ...

Has inventory volatility returned? A look at the current cycle
The massive liquidation of inventories during the 2001 recession contrasts sharply with the more moderate inventory movements observed in recent decades. While the rundown might be seen as evidence that firms are not managing their inventories as effectively as some economists have claimed, a careful analysis of inventory behavior in 2001 suggests that during much of the recession, firms were successfully regulating their inventories to avoid a large buildup of excess stock.

What drives housing prices?
This paper develops a growth model with land, housing services, and other goods that is capable of explaining a substantial portion of the movements in housing prices over the past forty years. Under certainty, the model exhibits a balanced aggregate growth, but with underlying sectoral change. The paper introduces a Markov regime-switching specification for productivity growth in the nonhousing sector and shows that such regime switches are a plausible candidate for explaining - both qualitatively and quantitatively - the large low-frequency changes in housing price trends. In particular, ...

Explaining the gap between new home sales and inventories
For much of the last four decades, the stock of unsold new homes has tracked sales very closely. Since 1995, however, inventories have fallen far behind rapidly advancing sales. What accounts for the change? Market trends have both reduced the need for inventories and slowed the response of inventories to shifts in demand. At the same time, the long current expansion has strained the resources of the building industry, creating supply shortages and raising costs.

Macroeconomic implications of changes in micro volatility
We review evidence on the Great Moderation in conjunction with evidence about volatility trends at the micro level. We combine the two types of evidence to develop a tentative story for important components of the aggregate volatility decline and its consequences. The key ingredients of the story are declines in firm-level volatility and aggregate volatility ? most dramatically in the durable goods sector ? but the absence of a decline in the volatility of household consumption and individual earnings. Our explanation for volatility reduction stresses improved supply chain management, ...
