This article provides a framework for designing and evaluating corporate risk management and hedging programs. Corporate risk management has the potential to create substantial shareholder wealth by protecting companies from unexpected events that could force them to put their strategic investment plans on hold or even endanger their existence. However, assessing the performance of risk management, and how it is expected to increase the value of the enterprise, is a difficult undertaking because the costs of risk management tend to be much easier to quantify—indeed, they often appear directly on the firm's bottom line—than the benefits. The author begins by discussing how to evaluate the benefits and costs of a risk management program in general terms, and then focuses more directly on the assessment of corporate hedging programs, which are generally conducted with derivatives. In practice, there are many obstacles to designing and carrying out a successful hedging program. But one of the most common has been the tendency of top managements to insist that hedging programs be “costless.” The author argues that just as the purchase of fire insurance is not viewed as waste of funds or a bad investment if the insured house does not burn down, the use of derivatives in a well‐designed hedge should not be viewed as a mistake if the derivative position produces losses. To guard against this mistake, the people who design and implement risk management strategies must ensure that their CEOs and boards understand the possible outcomes of the strategy—including losses on derivatives position—and how the strategy itself increases the (expected) value of the firm. Further, management should attempt to communicate the principles underlying its risk management program and the value created by its hedging strategy to the investment community.  相似文献

We find necessary and sufficient conditions for the market symmetry property, introduced by Fajardo and Mordecki (Quant Finance 6(3):219–227, 2006), to hold in the Ornstein–Uhlenbeck stochastic volatility model, henceforth OU–SV. In particular, we address the non-Gaussian OU–SV model proposed by Barndorff-Nielsen and Shephard (J R Stat Soc B 63(Part 2):167–241, 2001). Also, we prove the Bates’ rule for these models.  相似文献

In this paper we analyse whether entrepreneur location decisions differ across industries and identify the factors determining the choice of location between rural and urban environments. Firm location is based on a new taxonomy developed over the influential three dimensions of Hayter’s (1997) approach. The paper uses data from sample of one thousand Portuguese firms. We present a stylized theoretical model to determine how these new five dimensions influence firm’s location and test the model through a logistic regression. Our results show that that the location decisions depend on the sector of activity, type of area (urban vs. rural) and the characteristics of the entrepreneur. We find that companies engaged in knowledge intensive business services prefer to locate in urban areas. From an institutional point of view, firms prefer to locate in rural areas.  相似文献

This paper provides an approach to the measurement of the “scale effects” in the allocative profit efficiency. To be specific, we evaluate the improvements of profit that can be accomplished by means of a change in the scale size, once technical efficiency is achieved. New decompositions of the allocative efficiency into a scale effect component and the corresponding residual mix effect component are derived.  相似文献

In this paper, we give an example in which the price of tradable emission permits increases despite firms’ adoption of less polluting technology, a result that is in contrast with Montero (J Environ Econ 44:23–44, 2002) and Parry (J Regul Econ 14:229–254, 1998), among others. If two Cournot players switch to a cleaner technology, the price for permits may increase due to an increase in the net demand for permits and a decrease in the net supply of permits after the clean technology is adopted. This is only the case when output demand is quite elastic.  相似文献
