This paper investigates the impact of anti-scalping laws on the face value of tickets in professional football and baseball. Previous theoretical models have suggested that scalpers might cause an increase in prices at the ticket window because they represent an increase in demand. This paper provides a model in which ticket scalping has an ambiguous impact on ticket window prices, making the actual impact an empirical question. Empirical analysis suggest that in cities with anti-scalping laws average per-game season ticket prices are approximately $2 greater in baseball and $10 greater in football. Anti-scalping laws actually increase team revenues, as the laws have no adverse effect on attendance. Thus, event promoters might have sufficient pecuniary incentive to tacitly or explicitly support anti-scalping legislation. 相似文献

This paper explores the reasoning underlying Milton Friedman's preference for a small, unbalanced budget over a large, balanced one. Because the marginal return from government spending is less than the marginal cost (measured in terms of the amount of income private individuals remain free to spend), government expenditures have more of an adverse impact on the economy in his view than does the method of financing that spending. Using a panel data set comprising the 50 states plus the District of Columbia, we report evidence from the years 1967 through 1992 that growth rates in income per capita tend to be higher in states with smaller public sectors. Moreover, we find that while both deficits and taxes reduce the rate of income growth in a state, the negative impact of government spending is considerably larger at the margin. 相似文献

The dissemination of social program innovations that have been demonstrated to be effective through rigorous evaluation is an important issue. The classical dissemination framework emphasizes the position that programs implemented with fidelity to the original model are most likely to produce the positive outcomes demonstrated in the model's evaluation phase. However, critics suggest that local programs that are extensively modified are more likely to meet local goals and, therefore, are more likely to be sustained within the organization. The present research examined the implementation, effectiveness, and routinization of seven innovations replicated in a nationwide sample of organizations. The innovations were diverse in both content and implementing context and were located in a variety of sites, including schools, courts, prisons, police departments, and social service agencies. The results suggest that the innovations were replicated with acceptable levels of fidelity to the disseminated program models, and that higher-fidelity implementations tended to be more effective than those implemented with lower fidelity. The implications of the findings for social program dissemination policy are discussed and the authors propose an expansion of Berman's contingency model of innovation dissemination. 相似文献

Part of the conventional wisdom about the United States Supreme Court is the presumed existence of a freshman effect, a distinct pattern of behavior thought to be associated with newly appointed justices. Among other things, freshman justices are thought to be less likely than their senior colleagues to vote with established ideological blocs on the Court. The empirical evidence for the freshman effect in voting on the Court is somewhat ambiguous, however. In order to test for a freshman effect in the voting behavior of new justices on the Supreme Court, we examined the behavior of all justices on the Court between 1921 and 1990. Voting blocs were determined from the justices' interagreement scores, using the widely employed criterion developed by Sprague (1968). We found no evidence of a freshman effect during the time frame under study. Freshman justices do not differ from their senior colleagues with respect to bloc voting. We conclude that the freshman effect hypothesis is erroneous, at least with respect to the supposed nonalignment behavior of neophyte justices. 相似文献

Abstract: Pork ribs with intact muscle tissue were used in an experimental attempt to identify bullet wipe on bone at distances from 1 to 6 feet with 0.45 caliber, full metal jacket ammunition. This resulted in the unexpected finding of primer‐derived gunshot residue (GSR) deep within the wound tract. Of significance is the fact that the GSR was deposited on the bone, under the periosteum, after the bullet passed through a Ziploc® bag and c. 1 inch of muscle tissue. It is also important to note that the GSR persisted on the bone after the periosteum was forcibly removed. The presence of primer‐derived GSR on bone provides the potential to differentiate gunshot trauma from blunt trauma when the bone presents an atypical gunshot wound. In this study, the presence of gunshot primer residue at a distance of 6 feet demonstrates the potential for establishing maximum gun‐to‐target distance for remote shootings. 相似文献

The transition from 2D imaging to 3D scanning in the discipline of firearms and toolmark analysis is likely to provide examiners an unprecedented view of microscopic surface topography. The digital examination of measured 3D surface topographies has been referred to as virtual microscopy (VM). The approach offers several potential advantages over traditional comparison microscopy. Like any new analytic method, VM must be validated prior to its use in a crime laboratory. This paper describes one of the first validation studies of virtual microscopy. Fifty‐six participants at fifteen laboratories used virtual microscopic tools to complete two proficiency‐style tests for cartridge case identification. All participating trained examiners correctly reported 100% of the identifications (known matches) while reporting no false positives. The VM tools also allowed examiners to annotate compared surfaces. These annotations provide insight into the types of marked utilized in comparative analysis. Overall, the results of the study demonstrate that trained examiners can successfully use virtual microscopy to conduct firearms toolmark examination and support the use of the technology in the crime laboratory. 相似文献
