The paper extends Marx's law of value to include the effects of risk. It shows how risk has its origins in the labour process and is transferred between labour and capital on an unequal basis and between capitals on a zero sum basis. An empirical test is then presented, which shows that the employment of labour increases risk from the point of view of the investing capitalist. The conclusion is that the employment of labour is a curate's egg from capital's point of view. On the one hand it is essential for the production of sustainable surplus value and therefore for competitive advantage and capital accumulation. On the other hand employment of labour renders such accumulation inherently risky and therefore commensurately more costly to the rational capitalist investor.  相似文献

This study investigates the relationship between nominal long-term interest rates and central government budget deficits during the post-Bretton Woods era in Italy. The analysis is based in an open-economy, loanable-funds framework. The cointegration results indicate, among other things, the existence of a long-term positive relationship between the long-term interest rate and the deficit. An earlier draft of this paper was presented at the Forty-Fourth International Atlantic Economic Society Conference in Philadelphia, Pennsylvania, October 9–12, 1997.  相似文献

This paper presents a test of an important implication of Becker's theory of employer discrimination: when institutional change enhances labor mobility, employer discrimination falls because it becomes more costly for employers to indulge tastes for discrimination. The test case is the National Basketball Association (NBA). This paper specifically addresses the following question about the NBA: why did black/white player salary differentials vanish by the early 1990s? Previous studies claim that NBA wage gaps in the 1980s are attributable to customer discrimination and monopsonistic wage discrimination. This study argues that employer discrimination was an important source of those gaps and that one reason they vanished was because reduced monopsony power eradicated employer discrimination. Monopsony power fell because the 1988 NBA Collective Bargaining Agreement and the entry of four new teams in the league enhanced player mobility and increased the amount of labor market competition. Using data for the 1985-86 and 1990-91 seasons, employer discrimination was proxied by the race of the team's general manager. Empirical results strongly suggest that a major reason the NBA wage gap vanished in the later period was because of a reduction in employers' ability to discriminate. This is in contrast to earlier literature on the NBA, which has tended to emphasize the role of customer discrimination. (JEL J71)  相似文献

Various models or lenses have been used to predict and understand strategic decisions in organizations. This article examines four classes: (1) the unitary rational; (2) the organizational; (3) the political; and (4) the contextual. They are conceptualized as stemming from different assumptions about goal congruency and co-ordinative efficiency. the contextual view is especially highlighted, as it is a relatively new perspective, both organizationally and cognitively. A brief discussion is offered of disciplines and findings that either support or refute some of these models. Possible syntheses and reconciliations of the four views are explored, focusing on: (1) assumptional fit; (2) level of analysis; (3) cost of fashioning collective rationality; (4) information processing limits in organizational design; and (5) the role of adaptation lags and disequilibrium. the article concludes with a call for a meta-theory that places the various perspectives in a larger framework.  相似文献
