For New York Stock Exchange (NYSE) listed securities, the price execution of seemingly comparable orders differs systematically by location. In general, executions at the Cincinnati, Midwest, and New York stock exchanges are most favorable to trade initiators, while executions at the National Association of Security Dealers (NASD) are least favorable. These intermarket price differences depend on trade size, with the smallest trades exhibiting the biggest per share price difference. Collectively, these results raise questions about the adequacy of the existing intermarket quote system (ITS), the broker's fiduciary responsibility for “best execution,” and the propriety of order flow inducements. 相似文献

Predictive regressions are subject to two small sample biases: the coefficient estimate is biased if the predictor is endogenous, and asymptotic standard errors in the case of overlapping periods are biased downward. Both biases work in the direction of making t-ratios too large so that standard inference may indicate predictability even if none is present. Using annual returns since 1872 and monthly returns since 1927 we estimate empirical distributions by randomizing residuals in the VAR representation of the variables. The estimated biases are large enough to affect inference in practice, and should be accounted for when studying predictability. 相似文献

For a centrally planned economy in which the planners do not substitute among goods, either in production or consumption, in response to changes in relative prices, the short-run offer curve is in general backward-bending, and the planners will be indifferent as to whether the country is “small” or “large” in world markets as long as it faces an elastic foreign offer curve. The Soviet Union is found to have a backward-sloping offer curve in trade with the Western market economies. This suggests that systematic Soviet manipulation of this trade in order to earn monopoly profits is unlikely. 相似文献

This article argues that "differential and more favourable treatment"of developing countries in the General Agreement on Tariffsand Trade (GATT) has been a logical consequence of their owninward-looking policies and the GATT's implicit mercantilism,the latter implying that liberalization, being costly, shouldnot be demanded of relatively poor countries. Time has, however,reduced both the appeal of the protectionist model of developmentand the willingness of developed countries to accord differentialtreatment. The upshot has been pressure on more advanced developingcountries to "graduate" and a growing literature recommendingfuller and more equal participation of developing countriesin the GATT. The case for fuller and more equal participationis not self-evident. It needs to be assessed on its merits interms of the prospects for improved market access abroad andmore efficient policy at home. The analysis indicates that thepotential benefits should not be oversold. On balance, however,the most advanced developing countries would probably gain fromactive and more equal participation in both GATT and the multilateraltrade negotiations while the remaining developing countrieswould benefit from graduation by the more advanced. 相似文献

How should we understand the relationship between urban environments and infectious diseases? This article addresses this question from three particular perspectives: that of the materialities of health, that of nature and that of networks. The first perspective analytically blends biological dynamics, environmental influence and social practice. The second perspective, mainly influenced by multispecies ethnographies, foregrounds the liveliness and unboundedness of cities. Finally, the third perspective analyses how health is drawn into the domain of security. The article argues that while globalization and urbanization are often discussed as having triggered the emergence and spread of pathogens, urban epidemics are not self‐evident and ‘natural' consequences of these pro‐cesses. They do not fall neatly into universal categories of space, modernity or risk; rather, they are produced and shaped by a range of social, political, biological and economic sites and scales. Accordingly, the emergence of pathogens depends on its articulation through specific analytical frameworks. This article suggests that a critical focus on how infectious diseases manifest themselves differently in different local contexts may not only provide insights into the manifold forms of urban life, but also into the multiple, complex and highly political constitution of health. 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

We analyze the effect of worker inflows on establishments’ productivity, using German data. Previous studies for other countries have found positive effects of hiring workers from superior (more productive or higher paying) firms. Ranking establishments by their median wage, we find that inflows from inferior establishments seem to increase hiring establishments’ productivity. Further empirical analyses suggest our findings are due to a positive selection of such inflows from their sending establishments. These workers might have to find a better job match in order to advance their careers, an interpretation supported by the finding that the effect is driven by workers with short tenure at their previous employer. Our findings reflect the increasingly assortative pattern of worker mobility in Germany found in a related strand of literature. 相似文献

Abstract. We reexamine and extend tests of the uncertain information hypothesis (UIH) proposed by Brown, Harlow, and Tinic (1988, 1993). We find that their empirical results are sensitive to the sampling procedure employed and that their particular methodology does not sufficiently distinguish between event and nonevent periods. When the sampling procedure is modified to identify only relatively large, isolated events, the test results generally do not support the UIH. Instead, significant price shocks are consistently followed by short-lived price reversals. We observe this behavior following positive and negative events regardless of whether the event is classified as risk increasing or risk decreasing. 相似文献

This article tests for differences in execution costs among specialist firms for New York Stock Exchange listed securities. Execution cost differences provide a measure of the relative performance of specialist firms. We find a substantial difference in effective spreads and order processing costs across specialist firms, controlling for stock characteristics. While economically significant, the differences in execution costs between specialist firms are much smaller than the cross-market differences reported by Huang and Stoll (1996). Within a specialist firm, there is a positive relation between order processing costs and trading activity that is consistent with the hypothesis that active stocks subsidize inactive stocks. 相似文献
