The focus of this study is the habitual speculator in commodity futures markets. The speculator's activity broadens a market, creates essential liquidity, and performs an irreplaceable pricing function. Working knowledge of the profiles and motivations of habitual speculators is essential to both market theorists and policy makers. Responses to a 73-question survey were collected directly from retail commodity brokers with offices in Alabama. Each questionnaire recorded information on an individual commodity client who had traded for an extended period of time. The typical trader studied is a married, white male, age 52. He is affluent and well educated. He is a self-employed business owner who can recover from financial setbacks. He is a politically right-wing conservative involved in the political process. He assumes a good deal of risk in most phases of his life. He is both an aggressive investor and an active gambler. This trader does not consider preservation of his commodity capital to be a very high trading priority. As a result, he rarely uses stop loss orders. He wins more frequently than he loses (over 51% of the time) but is an overall net loser in dollar terms. In spite of recurring trading losses, he has never made any substantial change in his basic trading style. To this trader, whether he won or lost on a particular trade is more important than the size of the win or loss. Thus he consistently cuts his profits short while letting his losses run. He also worries more about missing a move in the market by being on the sidelines than about losing by being on the wrong side of a market move; that is, being in the action is more important than the financial consequences. Participating brokers confirmed that for the majority of the speculators studied, the primary motivation for continuous trading is the recreational utility derived largely from having a market position. © 1998 John Wiley & Sons, Inc.

We analyse the determinants of early settlement between merging parties and the European Commission over remedies that remove concerns of anticompetitive effects. This extends the previously narrow range of econometric literature on early settlement. Consistent with the theory of early settlement, our results confirm the importance of delay costs and of uncertainty, measured by the complexity of the economic analysis required for each merger. We also find a non‐monotonic effect of agency resourcing, which raises questions about the Commission's efficiency in times of high case load. Econometrically, we select a sample of merger decisions in which the European Commission intervened due to concerns of anticompetitive effects, and our selection model provides estimates of the factors determining intervention by the Commission. Conclusions are drawn for public policy. 相似文献

This study employs a customer interaction approach to examine how service organizations' strategic positioning relates to their human capital, and how the interaction between strategic positioning and human capital impacts organizational performance. Results from 234 service organizations in 96 different industries indicate very strong relationships between strategic positioning choices and human capital. We also find that certain combinations of strategic positioning and human capital result in superior performance. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

Antitrust and Vertical Integration in “New Economy” Industries with Application to Broadband Access 总被引:1,自引:0,他引:1
Bruce M. Owen 《Review of Industrial Organization》2011,38(4):363-386
Whether the firms that supply Internet hardware and software should face restrictions on the use of their property is an important and controversial policy issue. Advocates of “net neutrality”—including President Obama and the current FCC majority—believe that owners of broadband distribution systems (hardware used to distribute Internet and video services) and producers of certain “must-have” video content should be subject to prophylactic regulation that transcends present-day antitrust law enforcement. In the economic terms that are used in debates on competition policy, the concern is with vertical integration that may give firms both the opportunity (through denial of access or price discrimination) and incentive (increased profit) to restrict competition. This paper’s central point is that virtually every production process in the economy is vertically integrated, and economics predicts changes in the extent of vertical integration—that is, changes in the boundaries of the firm—in response to changes in relative prices, technology, or institutions. Both vertical integration and changes in the extent of vertical integration are benign characteristics of efficient, dynamic, competitive markets. While there is no shortage of theoretical models in which vertical integration may be harmful, most such models have restrictive assumptions and ambiguous welfare predictions—even when market power is assumed to be present. Empirical evidence that vertical integration or vertical restraints are harmful is weak, compared to evidence that vertical integration is beneficial—again, even in cases where market power appears to be present. Thus, it is reasonable to conclude that prophylactic regulation is not necessary, and may well reduce welfare. Sound policy is to wait for ex post evidence of harm to justify interventions in specific cases. Net neutrality, recently enacted by the FCC but subject to judicial review, is an unfortunate idea. 相似文献

Several major aspects of the metric conversion process occurring in the United States are examined by comparing a group of sample companies that have converted to metric production with a control group of nonconverting companies. Data files were used to relate several explanatory variables to the degree or percentage of metric production for individual companies and to compare the financial characteristics of converting and nonconverting companies. Smaller companies, on average, did more metric work for a single customer than large firms. In addition, as the percentage of metric work performed by companies increased, their dependence on a single buyer of their products tended to decrease. The analysis of the conversion process as a function of financial variables concluded that the conversion process was positively and significantly related to 1) long-term profitability, 2) liquidity, and 3) the size of firms as represented by the number of employees. Additional documentation is needed on the metric conversion process in distinct industries by firm size to more fully understand whether the process of technological diffusion is translated from large to small firms or begins in small firms themselves. 相似文献
