Communication in international business-to-business marketing channels: Does culture matter?

As business-to-business marketing channels become more international in scope, communication in channels occurs among a more diverse set of channel participants from different national cultures. Do such cultural variations influence channel communications and if so, how? This study examines these questions in international business-to-business marketing channels comprised of channel members representing different cultural contexts. The findings show that there is a relationship between culture and channel communication in international channels. This influence stemming from “cultural distance” may have significant implications as business moves into the E-commerce era of Internet-based B2B international channels of distribution.     

A Performance Comparison Between Cross-Sectional Stochastic Dominance and Traditional Event Study Methodologies

In this study, the performance of cross-sectional stochastic dominance (SD), first proposed by Falk and Levy (FL) (1989), is compared with three traditional event study methodologies: the Mean Adjusted model, the Market Adjusted model, and the Market and Risk Adjusted Returns model. The comparison technique we use is a simulations approach similar to that of Brown and Warner (BW) (1980). BW show that the Mean Adjusted and Market Adjusted Returns models perform as well as the more sophisticated Market and Risk Adjusted Returns model. FL, however, provide a very compelling argument against the three traditional event study methodologies. The problem, they note, is not the theoretical need for risk adjustment; it is the definition and measurement of risk. FL assert that the observed abnormal returns (or lack thereof) may be due to omitted variables, a market proxy effect, or other specification errors in implementing the traditional event study methodologies.The present research finds that SD analysis without the bootstrap method for statistical testing is not very useful at any level of abnormal return. However, when the bootstrap method of statistical testing is employed, SD is found to perform as well as, and sometimes better than, the three traditional models in detecting simulated abnormal performance at all test levels. The results are consistent with FL's assertion that the improved performance may result from the SD methodology being free from the specification errors inherent in the three traditional event study models.     

Robust portfolio choice with stochastic interest rates

We determine the optimal investment strategy for an ambiguity-averse investor in a setting with stochastic interest rates. The investor has access to stocks, bonds, and a bank account and he is ambiguous about the expected rate of return of both bonds and stocks. The investor can have different levels of ambiguity aversion about the two types of risky assets. We find that it is more important to take model uncertainty about the stock dynamics than model uncertainty about the bond dynamics into account. Furthermore, the investor’s ambiguity increases his hedging demand. Consequently, the bond/stock ratio increases with his ambiguity and implies less extreme positions in the bank account. Altogether, our model yields portfolio allocations which are more in line with what is implementable in practice. Finally, we demonstrate that neglecting model uncertainty implies significant losses for the investor.     

Probabilistic Bounds on the Virtual Multipliers in Data Envelopment Analysis: Polyhedral Cone Constraints

The paper is concerned with the incorporation of polyhedral cone constraints on the virtual multipliers in DEA. The incorporation of probabilistic bounds on the virtual multipliers based upon a stochastic benchmark vector is demonstrated. The suggested approach involves a stochastic (chance constrained) programming model with multipliers constrained to the cone spanned by confidence intervals for the components of the stochastic benchmark vector at varying probability levels. Consider a polyhedral assurance region based upon bounded pairwise ratios between multipliers. It is shown that in general it is never possible to identify a center-vector defined as a vector in the interior of the cone with identical angles to all extreme rays spanning the cone. Smooth cones are suggested if an asymmetric variation in the set of feasible relative prices is to be avoided.     

From the European Monetary System to Economic and Monetary Union — How and why?

The paper starts from the premise that the Delors Report is the main point of reference to create economic and monetary union in the EC countries. After a brief review of the Report, the study focuses on the transition phase leading to union and in particular to the gradual transfer of monetary authority to the EC level. It is argued that the attribution of (i) adjustment of short-term interest differentials, (ii) intervention policy vis-a-vis third countries and (iii) changes in reserve requirements to the European System of Central Banks would give this new collective body significant centralized authority, while leaving ultimate power to national governments concerning realignments in the transition stage.     

THE EFFECT OF FDICIA REGULATION ON BANK HOLDING COMPANIES

We examine market reactions to legislative announcements surrounding the passage of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) of 1991. Research shows that bank regulation adversely affects shareholder wealth on the one hand, yet often provides government subsidies on the other. The removal of Federal regulators' discretionary authority and the imposition of mandatory regulations in the FDICIA have an overall negative effect on our sample of bank holding companies. The results are consistent with either the costly regulation hypothesis or the decreased subsidies hypothesis.     

The magnitude and determinants of capital flight: The case for six sub-Saharan African countries

Summary Most studies treat capital flight as an exclusively Latin American problem. This paper estimates capital flight for six African countries and shows that the emphasis on Latin American capital flight is not correct. It appears that the burden of capital flight is also important for many African countries. Moreover, this paper tries to find some determinants for the African countries' capital flight. The increase of government and government-guaranteed foreign debt and the overvaluation of the real exchange rate appear to be the most important explanatory factors of capital flight for the African countries in this study.The authors would like to thank Peter van Bergeijk, Richard Brown, Nanne Brunia, Richard Gigengack, Ger Lanjouw, the participants of the Development Economics Seminar, March 1992, Institute of Social Studies, The Hague, and an anonymous referee for their useful comments.
