Better marketing to developing countries: Why and how

Managers have long understood the rationale for investing in new products. Now, however, they face an even more compelling need: to invest in targeting new markets, specifically those in less developed countries (LDCs). The argument presented in this article, for initiating or increasing marketing efforts in these nations, makes two related points. First, a healthy world economy requires consumers in developing nations—particularly China—to spend more, because trade imbalances between the United States and LDCs cannot be sustained. Second, in order to foster consumption in LDCs and to profit from it, marketing expertise in the developed world must refocus. Success will require devising, promoting, and distributing products that will overcome economic constraints in some markets, and in others will overcome an understandable reluctance to spend rather than save. We suggest that lessons may be gleaned from examples regarding recent efforts targeting LDCs by a pharmaceutical company (Pfizer) and a food supplement marketer (Procter & Gamble), as well as efforts pioneered in less developed countries themselves (including low-cost private schools and $2,500 automobiles).     

Professional codes: Why,how, and with what impact?

A tension between the professions' pursuit of autonomy and the public's demand for accountability has led to the development of codes of ethics as both a foundation and guide for professional conduct in the face of morally ambiguous situations. The profession as an institution serves as a normative reference group for individual practitioners and through a code of ethics clarifies, for both its members and outsiders, the norms that ought to govern professional behavior. Three types of codes can be identified — aspirational, educational and regulatory. All codes serve multiple interests and, as a consequence, perform many functions, eight of which are discussed. The process of developing a code of ethics is assessed because of the role it plays in gaining consensus on professional values and ethical norms. After discussing some of the weaknesses in current approaches to professional self-regulation, several new private and public initiatives are proposed.Mark S. Frankel is Head of the Office of Scientific Freedom and Responsibility of the American Association for the Advancement of Science, where he is Staff Director of the Association's Professional Ethics Program. Prior to joining AAAS, he was Director of the Center for the Study of Ethics in the Professions at the Illinois Institute of Technology in Chicago. His recent research and writings focus on the role of professional societies in promoting ethical practices by their members. He has conducted several workshops and seminars on ethics for corporate managers, scientists, and engineers.     

From global start-ups to the borderless firm: Why and how to build a worldwide value system

Although the original concept of international new ventures included the geographic configuration of value activities, the subsequent development of the literature has gradually abandoned the concern about the geographic configuration of both input sourcing and output marketing to concentrate almost exclusively on the latter. Therefore, this paper argues that there is a need to re-focus the research so as to figure out how and why some companies are borderless. Borderless firms are defined as the result of the combination, early on, of geographically dispersed resources and capabilities, defying the home-base logic. A borderless firm presents the following characteristics (or a combination of them) from inception (or shortly thereafter): (i) value-added activities dispersed across different countries and regions; (ii) entrepreneurs not bounded by a home base; (iii) multinational founders and/or management teams; and (iv) a multinational workforce. To enquiry into this issue, the study uses five case studies of borderless firms. The results advance the understanding of the motives and processes behind the development, early on, of a borderless configuration of value activities.     

How firms should hedge: An extension

This note studies a firm's optimal hedging strategy with tailor‐made exotic derivatives under both price risk and quantity risk. It extends the analysis of Brown G. W. and Toft K.‐B. (2002) by relaxing the assumption of a bivariate normal distribution. The optimal payoff function of a derivative contract is characterized in terms of the expectation and variance of the quantity, conditional on the price. This main result is illustrated by different examples, stressing the importance of the dependence structure between price risk and quantity risk for the choice of appropriate hedging instruments. © 2009 Wiley Periodicals, Inc.

Why smart executives fail: Four case histories of how people learn the wrong lessons from history

In a series of inductive case histories of leadership and strategy, we document the problem of how executives often learn the wrong lessons from history. The costs associated with such misdirected learning are significant, and often tally in the hundreds of millions to billions in losses. These mistakes are seldom due to managerial incompetence or random events, but rather are driven by common patterns of managerial behaviour. The case histories of two American and two Japanese companies highlight how and why apparently talented managers often learn the wrong lessons from history.     

Why and how do foreign institutional investors outperform domestic investors in futures trading: Evidence from Taiwan

A unique data set containing all transactions from the Taiwan Futures Exchange allows us to dissect the long-lasting outperformance of foreign institutional investors in this emerging market. We show that foreign institutional investors comprehensively outperform domestic investors in trade directions, submission types, trading counterparties, order sizes, and order aggressiveness. Although submitting passive orders increases the trading profits of each investor group significantly, particularly for foreign institutions, the most passive domestic trades still lose to the most aggressive foreign institutional trades. We suggest that information advantage plays a more important role than order submission strategy in foreign institutional investors’ superior performance.     

Emerging market hedge funds and the yen carry trade

For emerging market hedge funds, funding through the yen carry trade provides the possibility of enhancing returns by funding in a low coupon currency. This study examines whether emerging market hedge funds are exposed to the value of the Japanese yen and whether this is the key exposure associated with their use of leverage. The results suggest that the returns of these hedge funds are only weakly exposed to yen exchange rate but the use of leverage is associated with yen exposure, which implicates the importance of the yen carry trade.     

Robust estimation of the optimal hedge ratio

When using derivative instruments such as futures to hedge a portfolio of risky assets, the primary objective is to estimate the optimal hedge ratio (OHR). When agents have mean‐variance utility and the futures price follows a martingale, the OHR is equivalent to the minimum variance hedge ratio,which can be estimated by regressing the spot market return on the futures market return using ordinary least squares. To accommodate time‐varying volatility in asset returns, estimators based on rolling windows, GARCH, or EWMA models are commonly employed. However, all of these approaches are based on the sample variance and covariance estimators of returns, which, while consistent irrespective of the underlying distribution of the data, are not in general efficient. In particular, when the distribution of the data is leptokurtic, as is commonly found for short horizon asset returns, these estimators will attach too much weight to extreme observations. This article proposes an alternative to the standard approach to the estimation of the OHR that is robust to the leptokurtosis of returns. We use the robust OHR to construct a dynamic hedging strategy for daily returns on the FTSE100 index using index futures. We estimate the robust OHR using both the rolling window approach and the EWMA approach, and compare our results to those based on the standard rolling window and EWMA estimators. It is shown that the robust OHR yields a hedged portfolio variance that is marginally lower than that based on the standard estimator. Moreover, the variance of the robust OHR is as much as 70% lower than the variance of the standard OHR, substantially reducing the transaction costs that are associated with dynamic hedging strategies. © 2003 Wiley Periodicals, Inc.

An empirical analysis of the relationship between the hedge ratio and hedging horizon: A simultaneous estimation of the short‐ and long‐run hedge ratios

This article analyzes the effects of the length of hedging horizon on the optimal hedge ratio and hedging effectiveness using 9 different hedging horizons and 25 different commodities. We discuss the concept of short‐ and long‐run hedge ratios and propose a technique to simultaneously estimate them. The empirical results indicate that the short‐run hedge ratios are significantly less than 1 and increase with the length of hedging horizon. We also find that hedging effectiveness increases with the length of hedging horizon. However, the long‐run hedge ratio is found to be close to the naïve hedge ratio of unity. This implies that, if the hedging horizon is long, then the naïve hedge ratio is close to the optimum hedge ratio. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:359–386, 2004     

Emerging market hedge funds in the United States

This paper compares the performance and capital flow to emerging market hedge funds located in the US with those of the funds located in other countries. I find that the US funds on average provided neither a positive risk-adjusted return nor a liquidity premium to compensate for the stronger share restrictions they imposed than the other funds during 1994–2012. Quarterly flow to the US funds was 1.25 to 7.88 times higher but it was less sensitive to past performance. Smart money effect was observed among the Caribbean funds, Hong Kong funds and Singapore funds, but not among the US funds.     

Estimating the optimal hedge ratio with focus information criterion

In recent years, the error‐correction model without lags has been used in estimating the minimum‐variance hedge ratio. This article proposes the use of the same error‐correction model, but with lags in spot and futures returns in estimating the hedge ratio. In choosing the lag structure, use of the Akaike information criterion (AIC) and recently proposed focus information criterion (FIC) by G. Claeskens and N. L. Hjort (2003) is suggested. The proposed methods are applied to 24 different futures contracts. Even though the FIC hedge ratio is expected to perform better in terms of mean‐squared error, the AIC hedge ratio is found to perform as well as the FIC and better than the simple hedge ratios in terms of hedging effectiveness. © 2005 Wiley Periodicals, Inc.

Optimal hedge ratios in the presence of common jumps

This study derives optimal hedge ratios with infrequent extreme news events modeled as common jumps in foreign currency spot and futures rates. A dynamic hedging strategy based on a bivariate GARCH model augmented with a common jump component is proposed to manage currency risk. We find significant common jump components in the British pound spot and futures rates. The out‐of‐sample hedging exercises show that optimal hedge ratios which incorporate information from common jump dynamics substantially reduce daily and weekly portfolio risk. © 2009 Wiley Periodicals, Inc.

Why, when, and how to diversify? A comparison between Western theories and the cognition of Chinese enterprises

This paper uses as research samples 140 papers on enterprise diversification published in top-notch Western journals, and public statements from 30 influential contemporary Chinese CEOs on enterprise diversification. Both the qualitative open coding and the qualitative factor analysis are employed to analyze the two samples respectively, and then the corresponding analysis is utilized to explore the differences between Western theories and the cognition of Chinese enterprises on the motivation (why), timing (when) and industry choice (how) of enterprise diversification. Results show that, first, both consider the motivation of diversification mainly from the perspectives of resource-based view and asset portfolio theory. However, Western theories pay more attention to the factors related to the perspectives of the resource-based theory, transaction cost theory and agency theory, while Chinese enterprises put more emphasis on those factors associated with the asset portfolio theory, government policies and institutional theory. Second, on the cognition of the timing of diversification, Western theories insist that enterprises should diversify when they meet threats, while the practice of Chinese enterprises insists that diversification should take place when enterprises have enough strength. Third, Western theories focus more on the interrelationship between the original industry and the intended industry than on the attractiveness of the intended industry, while Chinese enterprises pay more attention to attractiveness than interrelationship.
