If actively managed mutual funds suffer from diminishing returns to scale, funds should alter investment behavior as assets under management increase. Although asset growth has little effect on the behavior of the typical fund, we find that large funds and small‐cap funds diversify their portfolios in response to growth. Greater diversification, especially for small‐cap funds, is associated with better performance. Fund family growth is related to the introduction of new funds that hold different stocks from their existing siblings. Funds with many siblings diversify less rapidly as they grow, suggesting that the fund family may influence a fund's portfolio strategy. 相似文献

Relationships between the potential productivity of land and property rights generally are couched in terms of measures of central tendency or means. However, risk or variance as a measure of uncertainty also is critical in relating property rights and organizational arrangements developed within various property regimes. Meteorological and hydrological research results support the appropriateness of risk-spreading property regimes, especially in semi-arid and arid lands. Spatial diversification models indicate that common property regimes can be a rational response to environmental variability. Efforts by the public sector to privatize and fence grazing lands on the extensive margin may have limited appeal to pastoralists throughout the world . 相似文献

A number of writers have argued in recent years that massive international currency substitution has been a major cause of exchange rate volatility and monetary instability in the United States and other major countries. Such analysis is frequently coupled with recommendations for a return to pegged exchange rates. This paper critically examines the evidence presented for this currency substitution view. It argues that the weight of latest research suggests that direct international currency substitution has not been of major quantitative importance for the U.S. However, empirical evidence supports traditional views that international capital mobility can generate substantial short-run monetary interdependence even under flexible exchange rates. Thus, even though international currency substitution is of little importance to U.S. monetary conditions, a broader range of international considerations may be of considerable importance for the U.S. economy. 相似文献

The 1993 Family and Medical Leave Act (FMLA) guarantees employees 12 weeks of unpaid leave. However, studies find either small or insignificant effects of the legislation on employment, work, leave-taking, and wages. Perhaps employees are unable to use the leave because it is unpaid or they do not need family leave because they already may take off work via vacation, sick leave, and disability leave policies. If so, then family leave legislation may have increased employer-provided family leave without corresponding effects on employment-related outcomes. This article examines family leave legislation's effects on employers' family leave policies, finding positive effects. (JEL J1, J2, J3 ) 相似文献

The theory of final offer arbitration promises more than its actual performance delivers, based on admittedly limited experience. There is no showing that fewer negotiations reach impasse than would occur under conventional arbitration. There is evidence, however, that final offer arbitration does tend to produce awards less equitable than warranted by the positions and strengths of the parties, particularly when there are multiple issues at impasse and when arbitrators may select only one overall package or another. This tendency is built-in to the process, since the whole point of final offer arbitration is deterrence, with little or no concern for getting a good settlement through arbitration. “Bad” awards cannot fail to generate irritation and to have a corrosive effect on responsible contract administration. It is possible that such awards, and their effects, will be accepted as the necessary price of a final offer selection system. What seems more likely, however, is that the system will be modified along the lines of those in Eugene and Michigan. Those modifications can be expected to have two effects. First, they will make it more likely that the parties will be able to reach their own agreement by encouraging mediation and further negotiations, even after arbitration has been invoked. Second, they will increase the possibility of an acceptable arbitrated settlement by allowing the arbitrator greater flexibility in making an award. By doing these things, however, the deterrent effect of final offer selection will be substantially weakened, and what will be left will be a useful form of mediation-arbitration but not a substitute for the strike which contains an equivalent incentive to negotiate. 相似文献
