Trust as a mediator of the relationship between leader/member behavior and leader-member-exchange quality

We examined how and why trust between a subordinate and supervisor develops over time from the separate perspectives and experiences of both dyad partners. Integrating the literatures on trust, leader-member-exchange (LMX) and promotion regulatory focus (PRF), we test our model using longitudinal data from a Malaysian subsidiary of a U.S. headquartered corporation. Subordinate's trust in supervisor mediated between supervisor's PRF and subordinate's experience of LMX quality; supervisor's trust in subordinate mediated between subordinate's job performance and leader's experience of LMX quality. Findings are interpreted within the high power-distance, high collectivist, and high performance orientation of Malaysian culture.     

Effect of Order of Contribution in a Sequential Public Goods Dilemma

This study examined how order of contribution in a sequential public goods dilemma affected cooperation. Under a sequential protocol of play, players of different levels of efficacy made decisions one after another. We contrasted a High-to-low versus Low-to-high Efficacy order in a nine-person game. Under a High-to-low order, high-efficacy players made decisions in positions 1–3, medium-efficacy players in positions 4–6, and low-efficacy players in positions 7–9. Under a Low-to-high order, the positions of high- and low-efficacy players were reversed. We hypothesized that cooperation rates would be higher in the High-to-low order that high-efficacy players (assigned in early positions), who would likely cooperate, would induce subsequent players to cooperate also. We found the anticipated effect that cooperation rate was higher in the High-to-low than the Low-to-high efficacy order. The efficacy order effect was the most prominent when people perceived that their group was becoming uncooperative. This study illustrates a new type of structural solution to social dilemmas that by systematically assigning people to different sequential positions, a group can be made more or less cooperative.     

Are New Zealand Business Students More Unethical Than Non-Business Students?

Using undergraduate students from the Waikato University in New Zealand as a sample, this study compared the ethical positions of students of different field of study and demographic characteristics. It was found that the ethical standard of business students are not significantly different from that of non-business students. The findings also suggest that female students are more ethical than male students, and senior students are more ethical than junior students.Besides sex and year of study, other variables studied were parents' occupation, religiosity and household income of the students. All these variables were found to have no significant impact on the ethical position of the students. Furthermore, all the interaction effects between the variables studied and the students' major field of study were nonsignificant.     

Spieltheoretische Analyse von Konflikt und Kooperation

Mit dem diesj?hrigen Nobelpreis für Wirtschaftswissenschaften wurden die Forscher Robert Aumann und Thomas Schelling für ihre spieltheoretischen Beitr?ge zu Konflikt und Kooperation in (wiederholten) Spielen ausgezeichnet. Inwieweit haben die beiden Forscher die Spieltheorie weiterentwickelt? Auf welche zentralen sozialwissenschaftlichen Fragestellungen lassen sich ihre Erkenntnisse anwenden?     

Daily short interest,idiosyncratic risk,and stock returns

This paper examines the relation between short selling and returns and the impact of arbitrage costs on short sellers’ behavior. Using daily UK short selling data, we find that stocks with low short interest levels experience significant positive returns on both an equal- and value-weighted basis. Economic theory predicts that short sellers avoid establishing positions in stocks with high idiosyncratic risk. Our results indicate a negative relation between short interest and returns among high idiosyncratic risk stocks and that short selling activity is mostly concentrated in low idiosyncratic risk stocks where it is less costly to arbitrage fundamental risk.     

Fashion retail forecasting by evolutionary neural networks

Recent literature on nonlinear models has shown that neural networks are versatile tools for forecasting. However, the search for an ideal network structure is a complex task. Evolutionary computation is a promising global search approach for feature and model selection. In this paper, an evolutionary computation approach is proposed in searching for the ideal network structure for a forecasting system. Two years’ apparel sales data are used in the analysis. The optimized neural networks structure for the forecasting of apparel sales is developed. The performances of the models are compared with the basic fully connected neural networks and the traditional forecasting models. We find that the proposed algorithms are useful for fashion retail forecasting, and the performance of it is better than the traditional SARIMA model for products with features of low demand uncertainty and weak seasonal trends. It is applicable for fashion retailers to produce short-term retail forecasting for apparels, which share these features.     

Social Media Influencers as a Crisis Risk in Strategic Communication: Impact of Indiscretions on Professional Endorsements

ABSTRACT

Social media influencers (SMIs) are increasingly employed by organizations to amplify their strategic communication efforts. Yet, little is known about the impact an SMI’s personal indiscretion has on their endorsing organizations. This article examines the factors that trigger these crises and their effects on the organizational image. Five cases – PewDiePie (U.S.), Munroe Bergdorf (UK), James Charles (U.S.), Grace Mongey (Ireland) and Sarah Bowmar (U.S.) – were analyzed using Rapid Issue Tracking, a method to capture stakeholders’ sentiments. Findings showed that SMIs’ personal indiscretions trigger paracrises. Organizations typically used distancing strategies but adopted image repair situationally. Anchored on image repair theory, we propose a framework for crisis identification and response strategies. With the increasing use of SMIs in marketing, their potential as a new type of crisis trigger warrants attention.     

Off‐Market Buybacks in Australia: Evidence of Abnormal Trading around Key Dates

Off‐market share buybacks in Australia are often structured with the buyback price comprising a large dividend component (which may carry imputation tax credits) and a small capital component. This unique structure has the consequence that institutions on low tax rates stand to benefit most from selling shares into the buyback. In this article, we explore evidence of abnormal trading activities around key dates in the conduct of off‐market buybacks and investigate the drivers of these activities. We find evidence of abnormal trading activities around the initial announcement and the final announcement dates of the buyback. The significant differences in abnormal volumes between the buybacks with and without imputation tax credits highlight the importance of tax motivations in explaining abnormal trading activities in the shares of companies conducting off‐market buybacks, and are consistent with observed buying pressure around the announcement of the buyback.     

Angel investors’ selection criteria: A comparative institutional perspective

Despite the important role of angel investors as critical financial providers for new ventures, little is known regarding how the institutions present in very different institutional environments impact their investment decisions. While angel investors might be expected to make decisions based on similar selection criteria, they are also embedded within and affected by different institutional settings in which they invest, and as a result they give these criteria weight that are different from those of other investors. We compare angel investors’ selection criteria in China and Denmark utilizing a comparative institutional perspective. Utilizing a policy-capturing approach to understanding their decision criteria, we find that angel investors in China, embedded within relationship-based institutions, tend to rely more on strong ties such as family and friends in the management team. They also give risks less weight as compared with angel investors in Denmark, which operate within more rule-based institutional contexts. As with venture capitalists, angel investors modify their decision criteria to fit the local institutional conditions.
