Diffusion and Performance of Modular Production in the U.S. Apparel Industry

This article examines the determinants of the diffusion of team production systems (modular assembly) and the impact of these systems on firm performance relative to traditional assembly systems in the apparel industry. The article draws on an extensive survey providing detailed information on a wide range of manufacturing practices and retail relationships in the U.S. apparel industry. We find that recent diffusion of modular practices is driven primarily by the product market. We also show that modular systems affect business-unit performance (particularly operating profits) where they are combined with complementary investments in information systems linking apparel suppliers with retail customers.     

Inflation and Asset Returns in a Monetary Economy

Postwar U.S. data are characterized by negative correlations between real equity returns and inflation and by positive correlations between real equity returns and money growth. These patterns are closely matched quantitatively by an equilibrium monetary asset pricing model. The model also implies negative correlations between expected asset returns and expected inflation, and it predicts that the inflation-asset return correlation will be more strongly negative when inflation is generated by fluctuations in real economic activity than when it is generated by monetary fluctuations.     

The Quantity Theory is Always and Everywhere Controversial—Why?*

Controversy about the Quantity Theory has been marked by common themes since the 18th century. These include the definition of money, the relationship between correlation and causation, and the transmission mechanism. Controversy has continued because of the technical difficulty of sorting out the direction of causation running between money and prices, and, on a deeper level, because ideological concerns about the viability of market mechanisms are at stake in the controversy.
