The motivation and trading behavior of the leading cheese companies on the National Cheese Exchange are examined. Although only 0.2 percent of all cheese is sold on the NCE, it is used to formula-price 90-95 percent of the bulk cheese in the U.S. Kraft General Foods, the largest buyer of cheese in the U.S., was the dominant seller on the NCE during 1988-1993, with the apparent purpose and effect of depressing national cheese prices. Kraft's behavior is consistent with that of a barometric price leader that enjoys a significant degree of discretion in shaping the pattern of prices over a price cycle. As presently organized, the NCE facilitates market manipulation. 相似文献

At least 15 profit-structure studies using Federal Trade Commission Line-of-Business data have found either a significantly negative or no relationship between profits and market concentration when firm market share is included in the analysis. The findings reported here suggest that the FTC Line-of-Business data are for years in which cyclical factors seriously distorted the profit-concentration relationship. This hypothesis is supported by both annual cross-section regressions and pooled regressions for the period 1947–1990. 相似文献

The paper attempts to analyse the conditional β‐convergence and its sources for 32 African countries over the period 1960‐2008. The augmented Solow model with both gross domestic product (GDP) per worker and per capita income is estimated using the dynamic system generalized methods of moments (GMM) technique with the panel data. This is the first study on the sources of conditional β‐convergence for African countries. According to the results of the augmented Solow model, income convergence rates are lower than those of GDP per worker. Moreover, total factor productivity convergence, human capital convergence and capital labour convergence are contributing towards the convergence of GDP per worker in Africa. This means that growth in the poorest African countries is being augmented by “catch‐up factor,” which is good news for them. However, convergence in terms of GDP per worker is not being fully translated into income per capita convergence. The demographic structure in the African continent with its record of persistent population growth has played an important role in lowering the income convergence of its countries. 相似文献
