Here we consider the hedging roles of a price futures contract versus a revenue futures contract. In the absence of idiosyncratic output risk, the revenue contract almost always dominates the price contract. Idiosyncratic output risk provides conditions under which the price contract should dominate. When production risk is largely idiosyncratic, a producer with an anticipated long actuals position might combine a long revenue futures position with a short price futures position. © 2004 Wiley Periodicals, Inc.

Assuming portfolio returns are normally distributed, it is shown that both Sortino ratio (SR) and upside potential ratio (UPR) are monotonically increasing functions of the Sharpe ratio. As a result, all three risk‐adjusted performance measures provide identical ranking among investment alternatives. The effects of skewness and kurtosis are then evaluated within the Edgeworth‐Sargan density family. For the Sortino ratio, the above conclusion remains valid in the presence of negative skewness or excessive kurtosis. Similar results apply to the UPR with modifications. For all other cases, both SR and UPR provide exactly opposite ranking among investment alternatives to that suggested by the Sharpe ratio when the Sharpe ratio is large. Applications to futures hedging are discussed. Specifically, it is found that the Sharpe ratio may frequently lead to a smaller futures position than the other two ratios. © 2002 Wiley Periodicals, Inc. Jrl Fut Mark 22:483–495, 2002  相似文献

This paper examines the effects of Knightian uncertainty on a commodity futures market within the Newbery‐Stiglitz framework. It is shown that Knightian traders act more conservatively. In a partial trade equilibrium, risk aversion and Knightian uncertainty have qualitatively similar effects on the equilibrium price and the equilibrium trading volume. Full‐trade and no‐trade equilibria are likely to prevail when the producer and the speculator incur different Knightian uncertainty. Herein different impacts of risk aversion and Knightian uncertainty are observed. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:701–718, 2003  相似文献

This paper examines the effects of ownership structure and board characteristics on performance in publicly traded Taiwanese firms that are controlled by founding families. Results show that when shares are owned by institutional investors, particularly foreign financial institutions, firms perform better. However, where families are the major shareholders, this is not the case. In addition, boards that are independent of the financial interests of the founding family have a positive impact on performance, whether measured by accounting ratios, operating performance or the stock market.

Challenging anticompetitive acquisitions of nascent competitors is a top priority of the Antitrust Division of the U.S. Department of Justice. It is especially important that competition agencies remain vigilant of such acquisitions in platform markets, where indirect network effects and other market forces tend to preserve the status quo at the expense of smaller, more innovative rivals and potentially final consumers. This article discusses two such attempted acquisitions: (1) Visa’s acquisition of technology firm Plaid that threatened to disrupt Visa’s monopoly power in online debit; and (2) Sabre’s acquisition of Farelogix, which is a firm that allows airlines to connect directly to travel agencies and thereby disintermediates Sabre and other global distribution systems.

The role of corporate governance in FDI decisions: Evidence from Taiwan   总被引:2,自引:0,他引:2  
There has been a considerable literature on the determinants of why firms undertake foreign direct investment (FDI), but very little on whether firms with different governance characteristics are more or less likely to venture overseas. For example, are family-controlled firms more predisposed to FDI than firms, with similar attributes, but different forms of ownership? Does the presence of institutional shareholders suggest a greater propensity to invest abroad? Does the composition of the Board of Directors have an impact? Most extant studies of corporate governance focus on the impact of governance factors on firm performance. However, these performance outcomes are a function of the strategic decisions made by the firms, which suggests it might be useful to consider the relationship between corporate governance factors and particular strategic decisions. One example is the decision to undertake foreign direct investment. The two main strands of IB literature on the determinants of FDI have little or nothing to say about how corporate governance factors might affect the FDI decision. Both internalisation theory and the resource-based view see FDI primarily as a means by which firms can appropriate rents in overseas markets from the exploitation of their idiosyncratic resources and capabilities. This paper extends this literature by investigating the effects of governance factors on the decision to undertake FDI. In particular, we want to assess the impact upon the FDI decision of (a) the extent of family control, (b) the presence of domestic and foreign institutional shareholders, and (c) the composition of the Board of Directors. We investigate these effects using a sample of 228 publicly listed firms in Taiwan, and our results clearly indicate that family control and share ownership by domestic financial institutions in Taiwanese firms are associated with the decision to undertake FDI. We also find that corporate governance impacts in different ways with regard to Taiwanese FDI in China in comparison to Taiwanese FDI in the rest of the world.  相似文献

The dynamic minimum variance hedge ratios (MVHRs) have been commonly estimated using the Bivariate GARCH model that overlooks the basis effect on the time-varying variance–covariance of spot and futures returns. This paper proposes an alternative specification of the BGARCH model in which the effect is incorporated for estimating MVHRs. Empirical investigation in commodity markets suggests that the basis effect is asymmetric, i.e., the positive basis has greater impact than the negative basis on the variance and covariance structure. Both in-sample and out-of-sample comparisons of the MVHR performance reveal that the model with the asymmetric effect provides greater risk reduction than the conventional models, illustrating importance of the asymmetric effect when modeling the joint dynamics of spot and futures returns and hence estimating hedging strategies.  相似文献
