THE BLACK-SCHOLES EQUATION REVISITED: ASYMPTOTIC EXPANSIONS AND SINGULAR PERTURBATIONS

In this paper, novel singular perturbation techniques are applied to price European, American, and barrier options. Employment of these methods leads to a significant simplification of the problem in all cases, by reducing the number of parameters. For American options, the valuation problem is reduced to a procedure that may be performed on a rudimentary handheld calculator. The method also sheds light on the evolution of option prices for all of the cases considered, the results being particularly illuminating for American and barrier options.     

Uncovered interest parity: it works, but not for long

If an investor borrows in a low interest currency and invests in a high interest currency, the interest differential accrues in a lumpy manner, formally just like the dividend payments on a stock. The investor will receive the interest differential discretely at the point when a position is rolled over from one day to the next. A position that is not held open overnight receives no interest differential because intradaily interest rates are zero. Using a large data set of intradaily exchange rate data, we run uncovered interest parity (UIP) regressions over different short time intervals taking careful account of the settlement rules in the spot foreign exchange market. We find results that are supportive of the uncovered interest parity hypothesis over very short windows of data that span the time of the discrete interest payment. However, adding even a few hours to the span of the window destroys the positive uncovered interest parity results.     

An interest rate defense of a fixed exchange rate?

Defending a government's exchange-rate commitment with active interest rate policy is not an option in first-generation models of speculative attacks. In those models, the interest rate is the passive reflection of currency-depreciation expectations. In this paper, we show how to adapt the first-generation framework to allow for an interest rate defense. It is shown that increasing domestic currency interest rate before the attack makes domestic assets more attractive according to an asset substitution effect, but weakens the domestic currency by increasing the government's fiscal liabilities. As a result, an interest rate defense can be successful only conditional on sound fiscal policy.     

Market size and tax competition

With international externalities, different country sizes, imperfect competition, and trade costs, tax competition for mobile firms is efficiency-enhancing with respect to the free market outcome. Under both scenarios, the resulting inefficiencies in international specialization and trade flows vanish when trade costs are low enough. Otherwise, only international tax coordination can implement the efficient spatial distribution of firms.     

Spillovers from foreign direct investment and firm growth: technological,financial and market structure effects

This article examines spillover effects from inward investment on domestic firm growth in the case of a developed host country. The emphasis is placed on the role of the technological gap between domestic and foreign firms in identifying the importance of technology diffusion from the presence of multinationals. An augmented production function is employed to account for technological, financial and market structure effects. Based on a sample of 2589 manufacturing firms operating in Greece between 1992 and 1997, the analysis provides evidence that the significance of spillovers varies with the relative technological position of domestic firms and is higher in the middle and upper quantiles of the growth distribution. It was estimated that a unit increase in the foreign presence in Greek industry raises output growth by 7% on average, in a five‐year period, after controlling for technological differences among firms. This result is consistent with the ‘absorptive capacity’ hypothesis that the technological capability of the host country relates positively to FDI spillover benefits.     

Antecedents of cognitive age: A replication and extension

Cognitive age has been an important construct in studies of older consumers. The present study builds upon previous research by providing theory‐based antecedents of cognitive age. The results suggest that differences in cognitive age do not merely reflect differences in chronological age, and that a person's cognitive age is influenced by his or her experiences of life events that serve as markers of transitions into social roles people are expected to enact at different stages in life. In addition, the experiences of health‐related events, such as chronic conditions, make people aware of their aging, affecting their cognitive age. The influence of cognitive age on consumer‐behavior variables is also examined, and directions for future research are suggested. © 2005 Wiley Periodicals, Inc.     

Shaping Ethical Perceptions: An Empirical Assessment of the Influence of Business Education,Culture, and Demographic Factors

Recent events at Enron, K-Mart, Adelphia, and Tyson would seem to suggest that managers are still experiencing ethical lapses. These lapses are somewhat surprising and disappointing given the heightened focus on ethical considerations within business contexts during the past decade. This study is designed, therefore, to increase our understanding of the forces that shape ethical perceptions by considering the effects of business school education as well as a number of other individual-level factors (such as intra-national culture, area of specialization within business, and gender) that may exert an influence on ethical perceptions. We found significant effects for business education, self-reported intra-national culture, area of specialization within business, and gender for some and/or all areas of ethics examined (i.e., deceit, fraud, self-interest, influence dealing, and coercion). One of our most encouraging findings is that tolerance for unethical behavior appears to decrease with formal business education. Despite the prevalent stereotype that business students are only interested in the bottom line or that business schools transform idealistic freshman into self-serving business graduates, our results suggest otherwise. Given the heightened criticism of the ethicality of contemporary managerial behavior, it is heartening to note that, even as adults, individuals can be positively affected by integration of ethics training.     

Sony Online Entertainment: EverQuest® or EverCrack? Oxford Style Debate Presented at Tenth Annual International Conference Promoting Business Ethics

Part C of this three part series is the presentation from the Oxford style debate held at the Tenth Annual International Conference Promoting Business Ethics between Laura Hartman, J.D., and Dr. Moses Pava on topics related to the EverQuest^? v. EverCrack case (Part B). In a traditional Oxford style debate, two debaters take opposing viewpoints and the third debater argues the neutral position. At the Conference, the modified format featured the two debaters presenting diametrically opposing views – corporate responsibility versus personal responsibility. This modified format was also used during the Ethics Awareness Week (Part A), with University professors presenting the debate before the student body. Ms. Hartman’s position focused on the personal responsibility by Mr Woolley while Dr. Pava opined that Sony Online Entertainment had corporate responsibility toward Mr. Woolley and all other individuals similarly situated.     

BEA's Regional Economic Accounts Program: Recent and Planned Improvements

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     

Toward an Understanding of Religiousness and Marketing Ethics: An Empirical Study

This study examines the influence of religiousness on different components of marketing professionals' ethical decision making: personal moral philosophies, perceived ethical problem, and ethical intentions. The data are from a national survey of the American Marketing Associations' professional members. The results generally indicate that the religiousness of a marketer can partially explain his or her perception of an ethical problem and behavioral intentions. Results also suggest that the religiousness significantly influences the personal moral philosophies of marketers.
