Risks and returns in international currency futures

Conclusion This paper analyzed the risk/return level of international currency futures traded on International Monetary Market of Chicago during 1972–1977 period. The empirical results indicate that relative risk and returns for each currency future studied are both close to zero during the sample period. The fact that the beta value for currency futures is close to zero implies its returns are uncorrelated with the market portfolio. Therefore, investors can reduce the risk level of their total portfolio significantly by adding currency futures.     

The Treatment of Market Power in Korea

Competitive forces have been relatively weak in Korea. Control of the chaebols' diversified expansion and conglomerate power has been a primary object of government policies. Competition law and policy has been expanded to include direct controls on chaebols, but it has been rather ineffective in resolving chaebol-related problems mainly because of insufficient attention having been paid to the problems of market power. Attempts to rein in chaebols by direct controls, without enhancing competitive forces, will be in vain, insofar as chaebol problems are really symptoms of their entrenched market potions in a non-competitive environment.     

Endogenous formation of coalitions with composite goods

We construct a model of endogenous formation of coalitions when three goods are necessary for a composite good, and composite goods are substitutes for each other. This analysis extends Economides and Salop’s [Journal of Industrial Economics XL (1992) 105] model of composite goods where two goods are necessary. We analyze the welfare implications of coalition structure, and investigate which coalition structure leads to the highest social welfare. The paper investigates whether the most desirable coalition structure represents an equilibrium, and provides a sufficient condition for the socially efficient coalition structure to be a stable Nash coalition structure.     

TQM practice in maquiladora: Antecedents of employee satisfaction and loyalty

In this study, we investigate the transferability of TQM practices to offshore manufacturing firms by validating direct and indirect relationships among top management commitment, HR-focused TQM practices, employee satisfaction, and employee loyalty. Our research objective is to isolate critical TQM practices that would enhance employee satisfaction and loyalty among maquiladora workers. On-site surveys were conducted at two leading maquiladora firms that have long implemented TQM. The statistical results indicate that employee empowerment, teamwork, and employee compensation have a significant and positive influence on employee satisfaction. The improved employee satisfaction leads to a higher level of employee loyalty. In addition, the results indicate that the effects of top management commitment on employee empowerment and teamwork are significantly mediated by employee training, implying that the success of employee empowerment and quality teams can be dependent upon the level of employee training.     

Probabilistic forecasting of output growth,inflation and the balance of trade in a GVAR framework

We apply a global vector autoregressive (GVAR) model to the analysis of inflation, output growth and global imbalances among a group of 33 countries (26 regions). We account for structural instability by use of country‐specific intercept shifts, the timings of which are identified taking into account both statistical evidence and our knowledge of historic economic conditions and events. Using this model, we compute both central forecasts and scenario‐based probabilistic forecasts for a range of events of interest, including the sign and trajectory of the balance of trade, the achievement of a short‐term inflation target, and the incidence of recession and slow growth. The forecasting performance of the GVAR model in relation to the ongoing financial crisis is quite remarkable. It correctly identifies a pronounced and widespread economic contraction accompanied by a marked shift in the net trade balance of the Eurozone and Japan. Moreover, this promising out‐of‐sample forecasting performance is substantiated by a raft of statistical tests which indicate that the predictive accuracy of the GVAR model is broadly comparable to that of standard benchmark models over short horizons and superior over longer horizons. Hence we conclude that GVAR models may be a useful forecasting tool for institutions operating at both the national and supra‐national levels. Copyright © 2010 John Wiley & Sons, Ltd.     

The future of development economics: a methodological agenda

This paper discusses methodological differences between universalismand particularism in development economics by focusing on the‘East Asian Miracle’ debate. It proposes to builddevelopment economics as part of hetero-economics, not mono-economics,following Max Weber's methodology of social science, and suggestsdeveloping intermediate theories by abstracting directly fromgiven comparative settings. It also discusses the limitationsthat are inherent in this method, as well as ways to employthe method in actual analyses. This paper argues that the futuretask of development economics lies in recombining existing theoriesand developing new, complementing theories that will systematicallydelineate the diversity of developing countries.     

Risk Taking as Self Discipline in Contractual Relationships

This paper considers an agency model in which the principal is privately informed of her production technology. In our model, the principal can require the agent to adopt the principal’s technology for production, or alternatively, to adopt a technology in the market. Information about the market technology’s efficiency is publicly available, and thus can be acquired. We show that, if the variation in technological efficiency is large, the principal prefers to delay acquisition of information about the market technology. The reason is that, the principal uses uncertainty as a device to provide a truth‐telling incentive to herself, which, in turn, lowers the cost of inducing the agent to accept the contract.     

Building relationships through dialogic communication: organizations,stakeholders, and computer-mediated communication

Online media are integral to daily life, and while many organizations use them to reach broad audiences, others still appear to be uncomfortable with online media because they do not understand how to maximize their potential to interact effectively with stakeholders. Numerous organizations use online media for one-way communication to disseminate information, despite the affordances of the media platforms for two-way, dialogic communication. This article draws on two dominant interpersonal theories of computer-mediated communication—social information processing theory and the hyperpersonal model—to propose dialogic strategies that organizations can use to improve their online communication with their stakeholders. We illustrate the application of these principles through three stages of relationship building: initiating/experimenting, intensifying, and integrating/bonding. The article integrates the applications within an overall dialogic communication strategy, and provides organizations and practitioners with a model with which they can engage stakeholders with dialogic methods via social media.     

Gender Inequality and Economic Growth in Korea

Calibrating an endogenous‐growth model to Korean data, we analyse the impact of gender inequality in Korea on long‐term economic growth. We find that gender equality policies that lower discrimination in the labour market or that increase the time spent by a father on childrearing can contribute positively to female labour market participation and per capita income growth. The simulation results show that when the disparities between men and women at home and in the labour market are completely removed, the female labour force participation rate increases from 54.4 to 67.5%, and the growth rate in per capita income rises from 3.6 to 4.1% on average over a generation.     

When does electronic word-of-mouth matter? A study of consumer product reviews

Online consumer product reviews, a form of electronic word-of-mouth (eWOM), have attracted increased attention from researchers. This paper examines the persuasiveness of eWOM. Drawing on regulatory focus theory, the authors propose that the consumption goals that consumers associate with the reviewed product moderate the effect of review valence on persuasiveness. Data from lab experiments and actual online retailers suggest that consumers who evaluate products associated with promotion consumption goals perceive positive reviews to be more persuasive than negative ones (i.e., a positivity bias). Conversely, consumers who evaluate products associated with prevention consumption goals perceive negative reviews to be more persuasive than positive ones (i.e., a negativity bias).
