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, ...

Tracking productivity in real time
Because volatile short-term movements in productivity growth obscure the underlying trend, shifts in this trend may go unrecognized for years - a lag that can lead to policy mistakes and hence economic instability. This study develops a model for tracking productivity that brings in additional variables to help reveal the trend. The model's success is evident in its ability to detect changes in trend productivity within a year or two of their occurrence. Currently, the model indicates that the underlying trend remains strong despite recent weak productivity data.

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 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, ...

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 ...

Finite horizons, political economy, and growth
This paper analyzes the political economy of growth when agents and the government have finite horizons and equilibrium growth is inefficient. A "representative" government (that is, one whose preferences reflect those of its constituents) endowed merely with the ability to tax and transfer can improve somewhat on the market allocation but cannot achieve first-best growth. Efficiency requires in addition the ability to bind future governments. We argue that this ability is related to political stability, and provide empirical evidence that stability and growth-related policies (namely ...

Skilled labor -- augmenting technical progress in U.S. manufacturing
This paper examines the role of skilled labor in the growth of total factor productivity. We use panel data from manufacturing industries within the United States to assess the extent to which productivity growth in yearly cross-sections of U.S. manufacturing industries is tied to industry shares of skilled labor inputs. We find evidence of an explosion in skilled-labor augmenting technological progress during the period from approximately 1972 to 1981, which precedes a period of suddenly increasing wage inequality and rapid growth in the relative wages of educated and experienced workers. We ...

Education, political instability, and growth
Empirical evidence suggests a positive association between income levels and growth rates on the one hand, and political stability and educational attainment on the other. This paper develops a simple finite--horizon overlapping growth model that in the absence of institutions for precommitment has a political equilibrium with inefficiently low growth, low educational attainment, and high returns to schooling. In the model, the laissez-faire growth rate is inefficient due to an intergenerational externality in the decision to accumulate knowledge. We then contrast the efficient growth rate ...

Durable goods inventories and the Great Moderation
This paper revisits the hypothesis that changes in inventory management were an important contributor to volatility reductions during the Great Moderation. It documents how changes in inventory behavior contributed to the stabilization of the U.S. economy within the durable goods sector, in particular, and develops a model of inventory behavior that is consistent with the key facts about volatility decline in that sector. The model is calibrated to evidence from survey data showing that lead times for materials orders in manufacturing shrank after the early 1980s. Simulations of the model ...
