Quantitative impact of correlation errors on basket options with time‐varying correlations

This study examines the quantitative impact of correlation errors on basket options with time‐varying correlations and the risk measures (conditional) value‐at‐risk (VaR) in the framework of Basel II. The results show that risk measure misestimation due to correlation errors are the largest and most asymmetric for the at‐the‐money and out‐of‐the‐money basket option. Delta hedging of the basket option reduces risk but increases size and asymmetry effects substantially. Finally, the square‐root‐of‐time rule for VaR does not adjust adequately to correlation errors and consistently underestimates risk measures, which could lead to the VaR exceedance clustering observed during the recent financial crisis. © 2011 Wiley Periodicals, Inc.

What moves the gold market?

In this article, we provide a detailed characterization of the intraday return volatility in gold futures contracts traded on the COMEX division of the New York Mercantile Exchange. The approach allows the study of intraday patterns, interday ARCH effects, and announcement effects in a coherent framework. We show that the intraday patterns exert a profound impact on the dynamics of return volatility. Among the 23 U.S. macroeconomic announcements, we identify employment reports, gross domestic product, consumer price index, and personal income as having the greatest impact. Finally, by appropriately filtering out the intraday patterns, we find that the high‐frequency returns reveal long‐memory volatility dependencies in the gold market, which have important implications on the pricing of long‐term gold options and the determination of optimal hedge ratios. © 2001 John Wiley & Sons, Inc.

Organizational coordination, development proficiency, and on-time completion of development and international rollout: A contingency analysis of external environments

This study examines the moderating effects of external environmental variables on the relationships between organizational coordination, quality of implementation of new product development (NPD) activities, and on-time completion of (or timeliness in) product development and international new product rollout (INPR) among manufacturing firms in Korea. The results indicate that quality of marketing execution is of greater importance for achieving on-time NPD and multi-country rollout in markets where competitive intensity is high than when it is low. The positive effect of HQ-subsidiary relationships on INPR timeliness is strengthened in rapid rather than slower technology-change environments. By contrast, the positive effect of HQ-subsidiary relationships on INPR timeliness is weakened in high rather than lower competitive-intensity environments. In addition, the beneficial effect of cross-functional integration on NPD timeliness is weakened in markets characterized by a high rate of technological change. The article also discusses the theoretical and managerial implications of the findings.     

Asset specificity roles in interfirm cooperation: Reducing opportunistic behavior or increasing cooperative behavior?

Extant research offers two alternative mechanisms for relating the asset specificity of a cooperative relationship to partnership performance. Transaction cost economics argues that the specific assets invested in a partnership increase the hazards of opportunism. As firms select appropriate governance structures to reduce opportunistic behavior, performance increases. On the other hand, relational exchange theory suggests that asset specificity enhances the trust between partners, which in turn leads to more cooperative behavior and higher partnership performance. This paper tests both mechanisms simultaneously on a sample of procurement relationships between Hong Kong trading firms and their Chinese suppliers using SEM methods. Our results support the predictions of relational exchange theory more than those of transaction cost economics. The paper also discusses the role of the Chinese context on theory application.     

Direct and Multiplicative Effects of Ethical Dispositions and Ethical Climates on Personal Justice Norms: A Virtue Ethics Perspective

From virtue ethics and interactionist perspectives, we hypothesized that personal justice norms (distributive and procedural justice norms) were shaped directly and multiplicatively by ethical dispositions (equity sensitivity and need for structure) and ethical climates (egoistic, benevolent, and principle climates). We collected multisource data from 123 companies in Hong Kong, with personal factors assessed by participants’ self-reports and contextual factors by aggregations of their peers. In general, LISREL analyses with latent product variables supported the direct and multiplicative relationships. Our findings could lay the groundwork for justice research from a morality perspective in future.     

ENHANCEMENT OF THE APPLICABILITY OF MARKOWITZ'S PORTFOLIO OPTIMIZATION BY UTILIZING RANDOM MATRIX THEORY

The traditional estimated return for the Markowitz mean-variance optimization has been demonstrated to seriously depart from its theoretic optimal return. We prove that this phenomenon is natural and the estimated optimal return is always       times larger than its theoretic counterpart, where       with  y  as the ratio of the dimension to sample size. Thereafter, we develop new bootstrap-corrected estimations for the optimal return and its asset allocation and prove that these bootstrap-corrected estimates are proportionally consistent with their theoretic counterparts. Our theoretical results are further confirmed by our simulations, which show that the essence of the portfolio analysis problem could be adequately captured by our proposed approach. This greatly enhances the practical uses of the Markowitz mean-variance optimization procedure.     

Values and the Perceived Importance of Ethics and Social Responsibility: The U.S. versus China

This study examines the effects of nationality (U.S. vs. China) and personal values on managers’ responses to the Perceived Role of Ethics and Social Responsibility (PRESOR) scale. Evidence that China’s transition to a socialist market economy has led to widespread business corruption, led us to hypothesize that People’s Republic of China (PRC) managers would believe less strongly in the importance of ethical and socially responsible business conduct. We also hypothesized that after controlling for national differences, managers’ personal values (more specifically, self-transcendence values) would have a significant impact on PRESOR responses. The hypotheses were tested using a sample of practicing managers enrolled in part-time MBA programs in the two countries. The results indicate that nationality did not have a consistent impact on PRESOR responses. After controlling for national differences, self-transcendence values had a significant positive impact on two of the three PRESOR dimensions. Conservation values such as conformity and tradition also had a significant association with certain dimensions of the PRESOR scale. William E.

International spillovers of China's structural reforms

This paper sheds light on the international spillovers of China's reforms in upgrading industrial capabilities, liberalizing capital account, internationalizing the renminbi, and transition to flexible exchange rates. Drawing on two-country New Keynesian model of endogenous entry and portfolio adjustment, we find that China's industrial upgrading that peddles on yuan appreciation lifts all boats through global production network irrespective of capital account convertibility, degree of renminbi internationalization, and exchange rate reform. Feasibility of appreciation-driven upgrading is called into question, however, when renminbi reform and capital account liberalization go in parallel. We also show that international spillovers disappear once renminbi internationalization is associated with liberalized capital account and flexible renminbi exchange rates.     

Investigating the different approaches to importance–performance analysis

Importance–performance analysis (IPA) is an analytic technique that generates a two-dimensional importance–performance grid, where the values of importance and performance across attributes are plotted against each other. This technique is used to assist service and other firms in prioritizing areas for service improvement when resources are limited. This study contributes to service theory by first performing a comprehensive literature review of four different and commonly used approaches to IPA. Survey data from the ports sector are then used to elucidate the value and the distinctiveness of these four different approaches, and it is also shown how the underlying theoretical assumptions led to somewhat varying, and contradictory interpretations. Subsequently, novel guidelines for integrating results from these four different approaches are proposed. The study advances service theory by detailing the integration of the different approaches to make sense of the importance and performance of diverse service attributes. The integrative approach developed in this paper also provides practitioners with clearer guidance for the application of IPA.
