Candidate gene studies and the quest for the entrepreneurial gene

Candidate gene studies of human behavior are gaining interest in economics and entrepreneurship research. Performing and interpreting these studies is not straightforward because the selection of candidates influences the interpretation of the results. As an example, Nicolaou et al. (Small Bus Econ 36:151?C155, 2011) report a significant association between a common genetic variant in the DRD3 gene and the tendency to be an entrepreneur. We fail to replicate this finding using a much larger, independent dataset. In addition, we discuss the candidate gene approach and give suggestions to avoid the publication of false positives.     

Decline and variability in brand loyalty

In this paper, we examine the over-time behavior of brand loyalty for a large set of brands drawn from 21 consumer packaged goods categories. Using the brand-loyalty operationalization of Colombo and Morrison (1989), the following conclusions are obtained. First, little support is found for the often-heard contention that brand loyalty is gradually declining over time. Second, while the short-run variability around a brand's mean loyalty level is not negligible, no evidence is found that this variability has systematically increased over time, and it can be reduced considerably through a simple smoothing procedure. Finally, the brand-loyalty pattern for market-share leaders is found to be more stable than for other brands. The study findings were robust to variation in the time interval used to construct the switching matrices, and to different treatments of multiple purchases.     

Institutional Impediments to Voluntary Ethics Measurement Systems

In this paper, we argue that calls for widespread implementation of ethics measurement systems would be better informed by institutional economic analysis. Specifically, we assert that proponents of such systems must first recognize and understand the institutions that potentially impede such efforts. We identify two potential institutional impediments to measuring ethics and social responsibility. First, we suggest that neoclassical economics, supported by traditional business education and legal precedent, serves to reinforce the notion that shareholders are the primary corporate constituency group. Such an emphasis on the needs of shareholders severely hinders implementation of measurement systems that address the needs of multiple stakeholder groups. Second, we argue that the threat of litigation may constrain corporate managers from measuring and considering ethics and corporate social responsibility matters. In particular, managers may be reluctant to quantify various ethical concerns if the resulting measurements could be used as evidence against the corporation in a lawsuit.

Doing business in Poland: What U.S. managers need to know

Poland has been and continues to be the leader of the transition economies of Eastern Europe. This study provides an in‐depth look at the ongoing economic, legal, and administrative policies of the Polish government in laying the ground‐work for a free‐market society. With the smaller business in mind, we first examine how the government of Poland moved decisively to lay the cornerstone for a private‐sector economy. Next, we demonstrate how Poland redirected its political and legal processes for long‐term global business. Finally, we describe what the U.S. government is doing to help Poland become a better trading partner and what this means to interested American firms. While there are many deep‐seated positive changes throughout Poland as it becomes a more significant global business player, there also are many challenges that must be understood by interested U.S. businesses if their investments in Poland are to be successful. © 2004 Wiley Periodicals, Inc.     

Does Religion Matter? A Comparison Study of the Ethical Beliefs of Marketing Students of Religious and Secular Universities in Japan

This study was designed to examine the determinants of and differences between the ethical beliefs of two groups of Japanese students in religious and secular universities. Multiple regression analysis revealed that students of the Japanese religious university perceived that young, male, relativistic, and opportunistic students tended to behave less ethically than did older, female, and idealistic students. Students of the Japanese secular university perceived that male, achievement-oriented, and opportunistic students tended to behave less ethically than did female and experience-oriented students. Opportunism was found to be one of the most important determinants in explaining misconduct. Multivariate analysis of variance (MANOVA) and multiple discriminant analysis (MDA) revealed that students of the Japanese secular university tended to score higher on achievement and humanism, and lower on theism and positivism than did students of the Japanese religious university. In addition, students of the Japanese secular university were somewhat more sensitive to academic dishonesty practices than were students of the Japanese religious university.
