Is asymmetric mean-reverting pattern in stock returns systematic? Evidence from Pacific-basin markets in the short-horizon

This paper applies asymmetric nonlinear smooth transition generalized autoregressive conditional heteroskedasticity (ANST-GARCH) models to the analysis of mean-reversion and time-varying volatility in weekly index returns of the stock markets of nine countries in the Pacific-basin. It finds that the returns exhibit an asymmetric pattern of return reversals, viz., on average, a negative return reverts more quickly, with a greater magnitude, to a positive return than a positive return reverting to a negative one. The asymmetric pattern of return reversals is directly associated with the unequal pricing behavior on the part of investors. Following a negative return shock, investors do not appear to require any additional premium to the leverage effect; instead they actually neutralize the risk in the form of a reduced premium! The reduction in risk premium causes not only the current stock price to rise but also the realized negative return to revert faster with a greater magnitude.     

Exploring the Attitudes of Bottled Wine Distributors Toward Wine Producers in the Portuguese Wine Sector

The wine sector has unique features that have not been deeply studied. This study aims to explore the attitudes of bottled wine distributors toward wine producers in the Portuguese wine sector. Eleven interviews (about 60 min each) were carried out with all major wine distributor managers. The transcribed interviews were analyzed using qualitative software. Content analysis shows that distributors develop six main attitudes toward producers: (a) Long-term Relationship, (b) Cooperation, (c) Interdependence, (d) Product Quality, (e) Trust, and (f) Brand Image. Findings may help managers of the wine sector and promote favorable relationships with the distributing customers.     

Layoff victim's employment relationship with a new employer in Korea: effects of unmet tenure expectations on trust and psychological contract

Existing studies of psychological contract have largely focused on the effects of contract breach on employees' attitudes and the contract itself involving the same employer. Given that both workforce mobility and downsizing activities are increasing, it is important to understand how individuals' past employment experiences shape their relationships with their employers. The present study focuses on the effect of prior layoffs on relationships with new employers. We posit that furloughed workers experience layoff as a breach of the psychological contract of job security they have entered into with their employer. Longitudinal data collected from individuals who were re-employed following a layoff revealed that unmet tenure expectations in an employment relationship result in reduced trust in a new employer, which in turn negatively impacts the quality of psychological contracts with the new employer. The results also show that the relationship between unmet tenure expectations and trust was moderated by individual attributions regarding the cause of the layoff. The present findings suggest that the negative impact of contract breach experienced with one organization may carry over to subsequent organizational contexts.     

Moderating effects of consumer empowerment on the relationship between involvement in eco‐friendly food and eco‐friendly food behaviour

This study investigates the moderating effect of consumer empowerment on the relationship between involvement in and purchase behaviour towards eco‐friendly food. It uses the generalized linear model, with data from the 2017 Research on Food Consumption. The results showed that gender is related only to involvement in eco‐friendly food and this involvement is higher for women than for men. Moreover, involvement in eco‐friendly food, purchase empowerment, engagement empowerment and frequency of buying eco‐friendly food increase as age increases, with the highest increases observed at ages 40–49 and 50–59; the score for those older than these age groups was much lower, resembling an inverted U shape. Groups with high education and income levels presented high scores for involvement in eco‐friendly food, purchase empowerment, engagement empowerment and frequency of buying eco‐friendly food. Regarding the effects of involvement in eco‐friendly food, purchase empowerment and engagement empowerment on the frequency of buying eco‐friendly food, the main effects of involvement in eco‐friendly food and purchase empowerment as well as the interactive effects between involvement in eco‐friendly food and engagement empowerment were statistically significant.     

Evaluating the purchase behaviour of organic food by young consumers in an emerging market economy

Promoting consumer purchase behaviour of eco-friendly products is key to environmental sustainability. This research aims to investigate how different factors may enhance or impede young consumers’ intentions to purchase a specific type of eco-friendly product, i.e. organic food. Data were obtained from 289 respondents in an emerging market economy, i.e. Vietnam. Multivariate data analysis using structural equation modelling revealed that food safety concern, health consciousness and media exposure to food messages played integral roles in the formation of attitude towards organic food. Interestingly, consumers’ environmental concern and food taste were of little value in predicting their attitude. Notably, perceived barriers (i.e. high price, inadequate availability, poor labelling and extra time required) significantly impeded both attitude and purchase intention towards organic food. The insights gained from this research extend current knowledge about pro-environmental behaviour in developing countries and they have important practical implications for marketers and other key stakeholders.     

Corporate Governance and Financial Peer Effects

Growing evidence suggests that managers select financial policies partially by mimicking policies of peer firms. We find that these peer effects in capital structure choice are unique to firms operating under weak external corporate governance. Cross-sectional tests suggest that this finding is best explained by a quiet life hypothesis in which managers may be able to avoid the effort required to optimize financial policies and the scrutiny of market participants. Leverage ratios of mimicking firms display less sensitivity to a profitability shock. Finally, mimicking correlates to higher financing costs and lower future profitability, especially if it results in high leverage.     

Ethical Context and Ethical Decision Making: Examination of an Alternative Statistical Approach for Identifying Variable Relationships

The purpose of this study was to investigate the relationship between organizational ethical context and the individual ethical decision-making process. In addition, a new statistical approach combining cluster and discriminant analyses was developed to overcome violations of regression assumptions, which are commonly not identified and/or ignored in behavioral and psychological research. Using regressions and this new alternative method, the findings indicated that ethical context does indeed influence the various components of ethical reasoning. However, social desirability was the strongest predictor of ethical decision making, which raises new concerns about how this bias can confound business ethics research. Finally, the findings showed that the alternative method provided more useful and interpretive results, indicating that it has the capacity to influence future empirical work in the field of business ethics, particularly when dealing with data that do not satisfy regression assumptions. The implications and limitations of the study are discussed, and several noteworthy suggestions for future research are provided.     

Corporate Relations with Environmental Organizations Represented by Hyperlinks on the <Emphasis Type="Italic">Fortune</Emphasis> Global 500 Companies’ Websites

This study investigates corporate relationships with environmental organizations by examining hyperlinks in the corporate environmental responsibility (CER) sections of the Fortune 2008 Global 500 corporate websites. It is assumed that hyperlinked organizations either represent their current inter-organizational relationship or create symbolic relationships among organizations. Results show that Asian companies have fewer hyperlink relations with other organizations compared with those in North America and Western Europe. Network analysis also confirms that U.S. companies are explicitly connected with stakeholders for CER practices, and governmental organizations have a relatively central role in the global CER system. Nonprofit organizations are the most frequently hyperlinked with Fortune Global 500 corporations.     

Mean Reversion of Short-Horizon Stock Returns: Asymmetry Property

In this paper, we explore nonlinearity inherent in short-horizon return dynamics, which is characterized by an asymmetric mean-reverting property. Over the period of 1962:07–2003:12, both daily and weekly returns of three market indexes and individual stock returns exhibit a strong asymmetric reverting pattern in which a negative return reverts more quickly, with a greater reverting magnitude, than positive returns revert to negative returns. The observed asymmetric reverting pattern is not justified under the positive relationship between future volatility and risk premium, which is a key presumption in the time-varying rational expectation hypothesis. The asymmetric reverting behavior of stock returns explored by this paper corroborates the argument for the relative performance of “winner' and “loser' stocks that has been documented by contrarian literature.

The Roles Incubator Organizations in Hi-Tech Venture Creation in Korea

In order to examine the roles of incubator organizations (places where entrepreneurs work before they start their ventures), ten high-tech venture founders were interviewed. Based on these interviews, their experience at incubator organizations and subsequent performance were analyzed, and 11 hypotheses regarding the characteristics of incubator organizations were formulated. The hypotheses are: high-tech venture are more likely to succeed if their founders have had the opportunity to prepare a business plan, to develop the prototype of a new product, to be acquainted with other disciplines, to work together as a team, and to acquire various kind of capabilities such as market-specific know-how, entrepreneurial skills and financing know-how at incubator organizations. However, it is hypothesized that the opportunity to acquire technological know-how and traditional managerial skills at incubator organizations are not positively correlated with venture success. The technological know-how and managerial skills could be regarded as a necessary but not sufficient condition for successful ventures. As the first study about Korean incubator organizations, the cases and the discussion of the hypotheses provide insights and implications for future studies.
