Conclusion This paper is in part a study of the operation of futures markets. The empirical evidence presented suggests that futures markets do reduce price fluctuations of traded commodities. Despite these facts, Congress eliminated futures trading in onions at the request of onion growers and shippers. As is often the case with political actions, the losses from the law are spread over a large number of individuals who do not have the incentive to become informed or to lobby on the matter, while the gains accrue to a smaller group with sufficient interest to lobby. Thus, in addition to shedding some light on the operation of futures markets, this paper is also a new illustration of an old maxim in political economy. Over 200 years ago, Adam Smith [11, p. 128] noted, People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices. With the government becoming a larger and larger influence on the economy, producers are finding it to be more in their interest to organize with the assistance of the legislature.  相似文献

Moral Sanctuary is used in this paper as a metaphor for any theory which makes actions immune from moral criticism. Three arguments favoring moral sanctuaries for business activities are countered. Two of the arguments rest on faulty analogies. One compares business activities to games, another to the behavior of machines. The third rests on the claim that business is a unique activity. This position is rejected by a reductio ad absurdum argument; it entails the immunity of all professional activities from moral judgment. I argue that business managers are accountable to the combined requirements of professionalism and democratic citizenship, notions which are briefly described at the conclusion of the paper.  相似文献

There is a substantial theoretical literature on the potential effects of loyalty contracts, but relatively little empirical work. We employ the event study methodology to examine the competitive effects of exclusionary contracts in the ocean shipping industry, where they were the subject of an extended legal and political struggle. We find that some of the most important events in this conflict caused significant changes in shipping firms' stock returns, indicating exclusive contracts increased their profits. We then examine the effect of these events on net exporting industries' stock returns, and provide evidence that these contracts contributed to carriers' market power.  相似文献

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown   总被引:4,自引:0,他引:4  
Theory suggests that economic instruments, such as pollution taxes or tradable permits, can provide more efficient technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing dramatic decreases in allowed pollution – the U.S. petroleum industry's phasedown of lead in gasoline. Using a duration model applied to a panel of refineries from 1971–1995, we find that the pattern of technology adoption is consistent with an economic response to market incentives, plant characteristics, and alternative policies. Importantly, evidence suggests that the tradable permit system used during the phasedown provided incentives for more efficient technology adoption decisions.  相似文献

Managers, security analysts, investors, and the press rely increasingly on modified definitions of GAAP net income, known by such names as "operating" and "pro forma" earnings. We document this phenomenon and discuss competing explanations for the recent rise in the use of such modified earnings numbers and implications for the interpretation of related accounting research. Our results show that over the past 20 years there has been a dramatic increase in the frequency and magnitude of cases where "GAAP" and "Street" earnings differ. Further, there is a very strong bias toward the reporting of a Street earnings number that exceeds the GAAP earnings number. We also show that the market response to the Street earnings number has displaced GAAP earnings as a primary determinant of stock prices. Finally, through an analysis of earnings releases, we show that management has taken a proactive role in defining and emphasizing the Street number when communicating to analysts and investors.  相似文献

In this study we examine the association among confirming management forecasts, stock prices, and analyst expectations. Confirming management forecasts are voluntary disclosures by management that corroborate existing market expectations about future earnings. This study provides evidence that these voluntary disclosures affect stock prices and the dispersion of analyst expectations. Specifically, we find that the market's reaction to confirming forecasts is significantly positive, indicating that benefits accrue to firms that disclose such forecasts. In addition, although we find no significant change in the mean consensus forecasts (a proxy for earnings expectations) around the confirming forecast date, evidence indicates a significant reduction in the mean and median consensus analyst dispersion (a proxy for earnings uncertainty). Finally, we document a positive association between the reduction of dispersion of analysts' forecasts and the magnitude of the stock market response. Overall, the evidence suggests that confirming forecasts reduce uncertainty about future earnings and that investors price this reduction of uncertainty.  相似文献

Internet impacts on supply chain management   总被引:1,自引:0,他引:1  
The traditional way of managing supply chains has changed dramatically over the last 5 years. Face-to-face management, manual tracking systems, paper-dominated order processing systems, and wired communication links were the primary management tools available to logistics managers. Today, they are obsolete. The article provides an overview of some of the new tools and trends discussed in this issue, including website structure, e-purchasing, electronic marketplaces, building vendor relationships, and the use of the Internet in managing supply chains in China.  相似文献

Strategic Internet application trends in supply chain management   总被引:1,自引:0,他引:1  
The Internet is evolving as a powerful force in the new marketplace where the nexus of competition has changed from individual firms to efficient supply chain networks both between firms and within industries. This study explores Internet adoption patterns and operational applications in US supply chain networks. The data reveal that the integration of the Internet into supply chain management applications has increased and has moved away from indiscriminate application of novel Internet technologies towards becoming a focused endeavor with precise expectations and measurable goals. Specifically, the study finds that Internet usage within supply chains is maturing as evidenced by enhanced and increased productivity, reduced costs and increased profit for participating firms.  相似文献

Do Daily Price Limits Act as Magnets? The Case of Treasury Bond Futures   总被引:4,自引:0,他引:4  
This article examines price behavior in the U.S. Treasury bond futures market in the mornings after large overnight price moves, using data from 1980 to 1987. The article tests whether price behavior is affected by proximity to a price limit, and whether the effect is a magnet effect or a calming effect. In that period, the price tends to reverse direction after the morning open, and the reversal appears to reflect a calming effect of the price being close to the limit. An alternative hypothesis—that morning price behavior reflects the overnight price change rather than proximity to the price limit per se—is also tested, and does not perform as well in explaining price behavior.  相似文献

The study examines insider ownership in large and small firms in relation to market efficiency. Recent studies have found a positive and significant relation between inside ownership and stock market performance. Such a finding is predicated upon the idea that inside ownership minimizes agency costs caused by the conflict between hired managers and shareholders. It is argued here that semi-strong form market efficiency requires that all public information, including insider ownership, be quickly impounded into the price of a stock. If that is the case, the expected present value of a change in agency cost should be incorporated into the stock price shortly after any significant change in ownership. Hence, if the estimate is unbiased, the longer-term performance of firms should not be effected by such changes. The issue is examined for both large, well-known firms and for smaller, less-known firms. The hypothesis that markets are generally efficient with respect to insider ownership information is rejected.  相似文献
