Options on bond futures: Isolating the risk premium

The introduction of unspanned sources of risk (and frictions) implies that option prices include a risk premium. Prima facie evidence of the existence of risk premia in option prices is contained in the implied volatility smile patterns reported in the literature. This article isolates the risk premium (defined as the simple difference between estimated and observed option prices) on options on U.K. Gilts, German Bunds, and U.S. Treasury bond futures using models that include price jumps and stochastic volatility. This study finds that single and multi‐factor stochastic volatility models with jumps may explain the empirical regularities observed in bond futures. © 2003 Wiley Periodicals, Inc.

MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.     

E-Consulting in Virtual Negotiations

In the e-world where many of us live and work, virtual work arrangements will become increasingly commonplace. This paper reports on an exploratory study into the way in which consultants can ply their trade virtually with clients whom they never meet. US-located e-consultants provided advice to Hong Kong-located web site developers on the interface and content aspects of a website that was being developed for an international audience. Extensive analyses of the communication between the consultants and developers is undertaken, in parallel with an analysis of survey data obtained from the two sets of stakeholders. Lessons are drawn for future research and practice.     

A New Venture's Cognitive Legitimacy: An Assessment by Customers

Many legitimacy problems associated with new ventures appear to stem from a lack of customers' knowledge and understanding of the new venture. Of particular concern to entrepreneurs is cognitive legitimacy. The findings of this article suggest that customers appear to have a preference for greater rather than lesser information about a new venture's product, organization, and management (holding the content of that information constant). Furthermore, customers appear to use a contingent decision policy. For an independent startup business that is perceived as new on all three dimensions, priority should be given to building customer knowledge in the product, followed by building customer knowledge in the organization. Less attention should be given to building the customer's knowledge in the management team, although such actions still will build cognitive legitimacy.     

A RE-EXAMINATION OF THE EFFECT OF 12B–1 PLANS ON MUTUAL FUND EXPENSE RATIOS

In this paper we re-examine the effect of 12b–1 payments on mutual fund expense ratios by analyzing data from 1988 through 1991. The findings are consistent with previous studies that find charges are a dead-weight cost borne by shareholders. However, we show that this cost increases over time.     

The treatment of racial and sexual discrimination in economics journals and economics textbooks: 1972 to 1987

This article examines two decades of scholarly literature on discrimination and two decades of discussion of discrimination in economics textbooks. At first discrimination was taken seriously and policy responses adequate to the problem were advocated. Today this is a minority position. The article first traces the way thatJEL policies concerning indexing and abstracting have contributed to this change. Next textbooks are analyzed to show how this change is manifested in commonly used curricular materials. Finally, political preferences are shown to undergird crucial arguments like those concerning minimum wages. Conclusions linking ideology to research agendas are put forward.     

Incentives, Discretion, and Asset Valuation in Closed–End Mutual Funds

This paper studies earnings management using 363 closed–end mutual fund firm–years of data. Closed–end fund assets consist of unrestricted and restricted securities, and realized and unrealized income. While unrestricted securities are not subject to earnings management, restricted security values are largely discretionary. Managerial valuation of restricted securities is modeled as contingent on unrestricted returns relative to a performance benchmark. Four unrestricted performance regions are identified. Known multi–period compensation incentives become the basis for hypothesizing earnings management behaviors in the regions in the form of restricted security valuation. Across several benchmarks, the results are consistent with multi–period maximization rather than simpler single–period compensation maximization or income smoothing. Funds with extreme unrestricted performance show relatively larger income–decreasing earnings management, and funds with slightly–below benchmark returns show relatively larger income–increasing earnings management than those slightly above. These results clarify the relationship between complex earnings management behavior and managerial incentives.
