Antitrust law distinguishes vertical and horizontal restraints. A horizontal restraint is one which exists between competing firms supplying rival products in a market, and a vertical restraint is one which exists between firms that jointly contribute to supplying a particular product in a market. Horizontal agreements receive much closer antitrust scrutiny because they often enable firms to limit competition at the expense of consumers, while vertical restraints may be legal or illegal depending on whether they tend to enhance or reduce competition or the exploitation of market power. This paper argues that there are important vertical restraints that operate in sports leagues which have been mostly neglected in the literature but have a significant impact. We focus on intraleague restraints, where member clubs of a league agree to control the organization of league competition, and interleague restraints, where horizontal agreement such as the Reserve Clause relies on agreements not to compete for players competing in senior or junior leagues.

Valuation involves forecasting payoffs and discounting expected payoffs for risk. Forecasting is often seen as the province of the statistician, risk determination the province of asset pricing. This paper elaborates on the idea that financial forecasting, risk determination and valuation are a matter of accounting. Accounting not only provides information to forecast payoffs but also specifies the payoffs to be forecasted. Further, accounting determines the transition from the present to the future and thus implicitly the evolutionary parameters that a statistician might estimate for forecasting. Accounting also bears on risk determination in the way it handles uncertainty. Accordingly, accounting is involved in both the numerator and the denominator of a valuation model. Indeed, a valuation model is a model of accounting for the future, and the effectiveness of a valuation model rides on the accounting principles employed. 相似文献

Accounting is often criticized for omitting intangible assets from the balance sheet. This paper points out that the omission is not necessarily a deficiency. There is also an income statement, and the value of intangible (and other) assets can be ascertained from the income statement. Thus, calls for the recognition of 'intangible assets' on the balance sheet may be misconceived. The paper lays out the property whereby the income statement corrects for deficiencies in the balance sheet. It then explores the case where the income statement perfectly corrects for a deficient balance sheet and the case where it does so imperfectly. In the latter case, the paper then asks whether accounting in the balance sheet—by capitalization and amortization of intangible assets or carrying them at fair value—could remedy the deficiency in the income statement (or makes it worse). The investigation involves an analysis and valuation of Microsoft Corporation and Dell Inc., two companies presumed to posses a good deal of 'intangibles assets'. The paper is instructive, not only to those concerned with accounting issues but also to analysts attempting to value firms, like Microsoft and Dell, with assets missing from the balance sheet. 相似文献

This paper presents empirical evidence that trading in options contributes to both transactional and informational efficiency of the stock market by reducing the effect of constraints on short sales. The significantly higher average level of short interest exhibited by optionable stocks supports the argument that options facilitate short selling. We also find significant effects on option prices, related to the short interest in the underlying stock. We then present evidence that options also increase information efficiency. Earlier work, that is replicated and extended here, has suggested that short sale constraints cause stock prices to underweight negative information. Options appear to reduce that effect. 相似文献

The Price Impact and Survival of Irrational Traders 总被引:1,自引:1,他引:1

Milton Friedman argued that irrational traders will consistently lose money, will not survive, and, therefore, cannot influence long‐run asset prices. Since his work, survival and price impact have been assumed to be the same. In this paper, we demonstrate that survival and price impact are two independent concepts. The price impact of irrational traders does not rely on their long‐run survival, and they can have a significant impact on asset prices even when their wealth becomes negligible. We also show that irrational traders' portfolio policies can deviate from their limits long after the price process approaches its long‐run limit. 相似文献
