In contrast with current thinking that conglomerates are inefficient, this article begins by presenting arguments in favor of the size and structure of the large integrated oil companies, also known as "the supermajors." Among the advantages are tax efficiency, information flow, political and technological know-how, broad supplier and customer relationships, scale economies, cross-business economies of scope, brand power, and the ability to coordinate strategic initiatives across businesses. These advantages all translate into a lower cost of capital.
One problem, however, is that this lower cost of capital does not seem to be reflected in the target returns on capital currently set by the supermajors. Observing that the financial goal of a corporation is to maximize not its return on capital but rather the net present value of expected future cash flows and earnings, the authors argue that the majors need to make two major changes to current practice. First, their investment hurdle rates should be reduced from their current level of 14–15% to the weighted average cost of capital, which is estimated to run about 8–9%. Second, the actual returns on capital reported in published accounts are largely meaningless; and when evaluating new investments and existing operations alike, the companies must find an annual performance measure that better reflects the economic realities of the business. This paper recommends use of a performance measurement framework based on economic profit that should serve two critical purposes: it will encourage managers to undertake all value-increasing projects (not just those that will maintain or increase reported return on capital), and it will help the companies communicate their strategy and results to the investment community.  相似文献

Benartzi and Thaler [The Quarterly Journal of Economics 110 (1995) 73–92] offer a quasi-rational explanation for the equity premium puzzle. We reconsider their methodology and, making a simple modification to it, find that their analysis is not robust.  相似文献

DEFAULT RISK AND DIVERSIFICATION: THEORY AND EMPIRICAL IMPLICATIONS   总被引:2,自引:0,他引:2  
Recent advances in the theory of credit risk allow the use of standard term structure machinery for default risk modeling and estimation. The empirical literature in this area often interprets the drift adjustments of the default intensity's diffusion state variables as the only default risk premium. We show that this interpretation implies a restriction on the form of possible default risk premia, which can be justified through exact and approximate notions of "diversifiable default risk." The equivalence between the empirical and martingale default intensities that follows from diversifiable default risk greatly facilitates the pricing and management of credit risk. We emphasize that this is not an equivalence in distribution, and illustrate its importance using credit spread dynamics estimated in Duffee (1999) . We also argue that the assumption of diversifiability is implicitly used in certain existing models of mortgage-backed securities.  相似文献

This article highlights recent improvements and plans for further improvements to each of BEA’s major regional economic accounts programs. The improvements focus on the acceleration of release of the estimates and on the preparation of new and extended estimates. There also is a brief discussion on BEA’s research effort to improve the regional accounts.JEL Classification E010  相似文献

Customer discrimination may result in racial differences in the marginal revenue products generated by workers. College basketball data allow for direct comparisons of the racial differences in the marginal revenues generated by players. This article compares the revenue generating potential of the top black and white college basketball players. A highly skilled white college player generates over $100,000 in per game revenues as compared to around $30,000 for a black player of equal talent, providing a strong incentive for colleges to discriminate against recruiting black student-athletes.  相似文献

Condemnation of the long-and-short-haul discrimination has been nearly ubiquitous in the literature on economic theory and transportation. However, the French economist Dupuit developed a case against all transport regulation by relating it to a defense of the practice of place discrimination before the middle of the nineteenth century. He did so, moreover, within an early elaboration of a full price explanation of competitive functioning. This paper analyzes the idea in Dupuit's context and argues that this so-called form of price discrimination is actually an efficient and necessary form of the competitive process.  相似文献
