Roll has recently formulated an option pricing model which allows dividend payments on the underlying stock. This paper compares the performance of the exact Roll model with a modified, but inexact, Black-Scholes model. The results indicate that the Roll model prices are significantly closer to actual market prices. 相似文献

This paper uses data from the April 1993 pension supplements to the Current Population Survey (CPS) to investigate the impact of employer matching and employee tenure on participation levels in 401(k) plans. While earlier studies examine similar issues, this study makes several advances. First, consistent with the theory that employers may use matching contributions to satisfy nondiscrimination rules, the study shows that correcting for the endogeneity of employer matching substantially increases the estimated effect of matching on participation levels. Second, the study provides evidence that the large positive association between employee tenure and 401(k) participation is because "stayers" tend to be "savers." 相似文献

Two competing theories generally used, at least implicitly, to justify and analyze public resource management are scientific management and pluralism. We briefly review these theories and compare them to the new resource economics, an emerging body of theory which revises resource economics by introducing concepts from Austrian economics, property rights theory, and public choice. We argue that the new resource economics is superior to these traditional theories and then present specific policy proposals for the national forests, wilderness areas, and the public grazing lands. We also criticize new resource economists for not clearly distinguishing ideology from science, for emphasizing efficiency as a criterion for policy analysis, and for lacking political strategies for implementing their proposals 相似文献

This paper discusses a measure for estimating the wealth creation potential of capital investments in manufacturing. The measure, called “Economic Value Added,” has recently become popular in the United States and can be derived from an after-tax analysis of cash flows generated by a capital investment. A proposed investment in manufacturing capacity is analyzed to illustrate the after-tax cash flow calculations required to determine its EVA potential. 相似文献

The Settlement of Tithes of 1638 can be tested for biases in its London rents. Even so, it proves to be a relatively good source for seventeenth‐century London, and for calculating associated median and mean rents, as well as a Gini coefficient of inequality for the distribution of resources. Through other evidence in the Settlement, rent/income ratios for London can be approximated, and from them estimates made of London's median income. Median rents and income also allow estimates of the percentage of Londoners in poverty. Though the last is inevitably disputable, the estimate holds up well to testing by other evidence. 相似文献

This paper examines movements in the prices of target stocks as predictors of the ultimate success or failure of tender offers. An empirical investigation of 100% cash tender offers during the years 1976 to 1981 leads to the conclusion that, with few exceptions, market prices are well-calibrated, i.e., the current target price during the offer period measures the expected (discounted) stock price at the conclusion date. The market's probability predictions improve monotonically over time. 相似文献
