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. 相似文献

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. 相似文献

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. 相似文献

Transactions prices of S&P 500 futures options over 1985-1987 are examined for evidence of expectations prior to October 1987 of an impending stock market crash. First, it is shown that out-of-the-money puts became unusually expensive during the year preceding the crash. Second, a model is derived for pricing American options on jump-diffusion processes with systematic jump risk. The jump-diffusion parameters implicit in options prices indicate that a crash was expected and that implicit distributions were negatively skewed during October 1986 to August 1987. Both approaches indicate no strong crash fears during the 2 months immediately preceding the crash. 相似文献
