The number of firms using alliances as part of their corporate venturing or market entry strategies has surged over the past decade. Three common reasons cited for pursuing alliances are technology convergence, market access and alliance partners' complementary resources. This paper contrasts the alliance strategies of HP and IBM, two major competitors in electronic services (i.e. Internet-based 'e- service') businesses, using the Familiarity Matrix as a display tool to portray the strategies. Whereas the HP strategy is to attempt to establish its technology infrastructure as the standard e-services infrastructure on the Internet, IBM aims to position its IBM Global Services, rather than its technology, at the center of this ecosystem. 相似文献

The price movements of certain assets can be modeled by stochastic processes that combine continuous diffusion with discrete jumps. This paper compares values of options on assets with no jumps, jumps of fixed size, and jumps drawn from a lognormal distribution. It is shown that not only the magnitude but also the direction of the mispricing of the Black-Scholes model relative to jump models can vary with the distribution family of the jump component. This paper also discusses a methodology for the numerical valuation, via a backward induction algorithm, of American options on a jump-diffusion asset whose early exercise may be profitable. These cannot, in general, be accurately priced using analytic models. The procedure has the further advantage of being easily adaptable to nonanalytic, empirical distributions of period returns and to nonstationarity in the underlying diffusion process. 相似文献

Finance theory proposes that firms' cost of capital increases when market makers set wider spreads due to perceived higher information asymmetry across traders. Using a sample of UK investment property firms and controlling for firms' non-random selection of external monitors, we find evidence that market makers perceive information asymmetry across traders to be lower for firms employing external appraisers versus those employing internal appraisers. This evidence is consistent with liquidity-motivated traders being unable to overcome such reliability differences using asset value information from sources other than accounting. We fail to find a similar difference for firms employing Big 6 versus non-Big 6 auditors. Our findings contribute to the debate over the recognition of fair value estimates for long-lived tangible assets by documenting that reliability differences attributable to differential monitoring by appraisers can affect information asymmetry, and therefore firms' cost of capital. 相似文献

A bstract . Official perceptions of agriculture's role in economic development in the Eastern European Soviet-type economies have undergone significant alterations over the past several decades. These changes have been especially important in Hungary , a country well known for its unorthodox economic approaches. The modifications of status analyzed below have been consistent with the overall economic policy directives of the Communist party, including the current renewed emphasis on economic rationality, pragmatism , and the revitalization of the economic reform of 1968 . 相似文献

Following Parsian and Farsipour (1999), we consider the problem of estimating the mean of the selected normal population, from two normal populations with unknown means and common known variance, under the LINEX loss function. Some admissibility results for a subclass of equivariant estimators are derived and a sufficient condition for the inadmissibility of an arbitrary equivariant estimator is provided. As a consequence, several of the estimators proposed by Parsian and Farsipour (1999) are shown to be inadmissible and better estimators are obtained.

Competition was introduced into the electric utility industry with the passage of the Public Utilities Regulatory Policy Act (PURPA) of 1978. Increasing interest has appeared in structuring the PURPA purchase market into an auction system. This paper addresses the design issues associated with setting up such markets and introduces a simulation model to study them. The simulation analysis is guided by theoretical issues such as the alleged inefficiency of first-price auctions. We find that efficiency concerns raised about first-price auctions turn out to be less important than simple theoretical concerns would suggest. 相似文献

The paper addresses the problem of Fed control of the money supply and the inherent instability of a fractional reserve banking system which Friedman covered in A Program for Monetary Stability. While Friedman proposed a 100 percent reserve requirement as a solution, this work suggests a change from imposing legal reserve ratios on specific liabilities to one of imposing them on total bank liabilities. Reserve ratios are compared to tax rates. Friedman's proposal is to increase the tax rate to 100 percent on specific liabilities and pay interest on reserve balances at the Fed. The proposal of this paper is to keep the tax rates (present reserve ratios) but change the tax base. It is shown that the Fed would gain control over the maximum expansion of banks, but would lose direct control over specific liabilities. The Fed would not tax some liabilities and subsidize others. The Fed could concentrate on setting the tone of the money market and allow the public to use whatever set of bank liabilities it desires as money without specific penalty. 相似文献
