Dress for success: the effect of exhibitors’ dress conformity and self-construal on attendees’ approach behavior

ABSTRACT

The purpose of the current study is to investigate how attendees’ approach behavior is influenced by exhibitors’ dress conformity. A 2 × 2 between-subjects quasi-experimental design was utilized for this study. Our results showed that conforming dress for exhibitors can lead to a higher level of approach behavior of trade show attendees as compared with nonconforming dress, and the effect of exhibitors’ dress styles on approach behavior is moderated by attendees’ self-construal. Findings of this study provide significant insights for trade show exhibitors and attendees.     

Corroborating social media echelon in cancer research

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively.     

Hyperbolic normal stochastic volatility model

For option pricing models and heavy-tailed distributions, this study proposes a continuous-time stochastic volatility model based on an arithmetic Brownian motion: a one-parameter extension of the normal stochastic alpha-beta-rho (SABR) model. Using two generalized Bougerol's identities in the literature, the study shows that our model has a closed-form Monte Carlo simulation scheme and that the transition probability for one special case follows Johnson's distribution—a popular heavy-tailed distribution originally proposed without stochastic process. It is argued that the distribution serves as an analytically superior alternative to the normal SABR model because the two distributions are empirically similar.     

Demand for fair value accounting: The case of the asset revaluation boom in Korea during the global financial crisis

When the fair value accounting (FVA) option for property, plant, and equipment was introduced in the midst of the global financial crisis, a significant proportion of Korean firms elected FVA. We attribute this unusual boom in asset revaluations to the nation's culture of government intervention and civilian compliance, which was particularly espoused during this period of financial turmoil, and a foreseeable option to switch back to historical cost accounting. We find that among those firms whose debt‐to‐equity ratios are low, public firms opt for the FVA option more often than private firms, suggesting that the need to communicate fair value information with diversified equity holders is more important than the need to do so with creditors. In contrast, among those firms whose debt‐to‐equity ratios are high enough to warrant such unfavorable dispositions as new debt freezes and monitoring by regulators, we find no difference in the FVA choice between private and public firms. These findings imply that during the global financial crisis, private firms that rely heavily on debt financing have a strong incentive to utilize FVA to comply with government guidelines for the debt‐to‐equity ratio and to ease a potential hold‐up problem by influential creditors.     

Are social entrepreneurs more risk-averse?

We have a conventional wisdom that risk-seeking behaviours are related to commercially oriented entrepreneurs. For this reason, most studies have focused on the context of commercial entrepreneurship, and thus we do not know the risk propensity of social entrepreneurs. Using the PSM method, contrary to our wisdom, we find that social entrepreneurs tend to more have about 15% risk-seeking propensity than commercial entrepreneurs.     

Weak‐instrument robust inference for two‐sample instrumental variables regression

Instrumental variable (IV) methods for regression are well established. More recently, methods have been developed for statistical inference when the instruments are weakly correlated with the endogenous regressor, so that estimators are biased and no longer asymptotically normally distributed. This paper extends such inference to the case where two separate samples are used to implement instrumental variables estimation. We also relax the restrictive assumptions of homoskedastic error structure and equal moments of exogenous covariates across two samples commonly employed in the two‐sample IV literature for strong IV inference. Monte Carlo experiments show good size properties of the proposed tests regardless of the strength of the instruments. We apply the proposed methods to two seminal empirical studies that adopt the two‐sample IV framework.     

Bertrand versus Cournot competition in a downstream mixed oligopoly with foreign ownership

Focusing on foreign ownership in the private firm, we examine the Cournot-Bertrand comparison in a mixed oligopolistic market with vertical market structure. We have found that if public and private firms were charged with uniform price for their inputs, then Cournot-Bertrand ranking in market outcomes confirms those obtained by Ghosh and Mitra (2010). This implies that under uniform pricing in the upstream sector, the vertical market structure does not have substantial influences on Cournot-Bertrand ranking. However, if discriminatory pricing is adopted, firm's profits, output, and social welfare are often reversed to those obtained from uniform pricing in the upstream sector. Given the closeness of products, if the share of foreign ownership is sufficiently low, social welfare in Cournot competition can exceed that of Bertrand competition, contrasting with the standard welfare ranking that Bertrand welfare is strictly higher than Cournot. This implies that Cournot competition can be more socially desirable than Bertrand in mixed oligopoly with vertical market structure if discriminatory pricing scheme is adopted by foreign upstream monopolists.     

The Effects of Four Dimensions of Strategic Orientation on Firm Innovativeness and Performance in Emerging Market Small- and Medium-Size Enterprises

We investigate the effects of technology, entrepreneurial, market, and learning orientations on firm innovativeness, and the mediating effect of firm innovativeness on these relationships, using a survey of 374 small- and medium-size enterprises in Korea. The results reveal that, while technology, entrepreneurial, and learning orientations significantly influence firm innovativeness, firm innovativeness has a significant effect on firm performance. We also find that firm innovativeness has a statistically significant mediating role in the relationships of technology, entrepreneurial, and learning orientations to firm performance. Our study contributes to strategic management and emerging market literature by identifying the pivotal role of innovativeness for firms that seek to benefit from various types of strategic orientations.     

Shareholder Conflict as a Determinant of Corporate Social Responsibility Commitment for Shared Growth

In this study, we seek to explore shareholder conflicts as a determinant of large firms' corporate social responsibility (CSR) commitment for shared growth with subcontractors. Using a sample of 232 firms in the Korean chaebols during 2006'12, we find that CSR commitment is negatively related to controlling shareholders' cash flow rights but positively related to control-ownership disparity. We also find that foreign blockholders mitigate the positive relationship between CSR commitment and control-ownership disparity. This study offers a view of how controlling shareholders and blockholders protect their interests while enhancing their reputations as good citizens through CSR commitment.     

Mitigating the Challenges of Partner Knowledge Diversity While Enhancing Research & Development (R&D) Alliance Performance: The Role of Alliance Governance Mechanisms

This article explores the answers to the following unresolved research question: How do firms mitigate the collaboration challenges associated with partner knowledge diversity and enhance alliance performance? The study provides an alliance performance enhancing framework by identifying two types of partner knowledge diversity: (1) technology base diversity and (2) R&D process experience diversity, and links them with R&D alliance performance. Additionally, the moderating effects of the two types of alliance governance mechanisms (i.e., interactive and contractual mechanisms) were examined to investigate which alliance governance mechanism is conducive to mitigate the collaboration challenges and enhance alliance performance. Using a data set of 316 alliances in the biopharmaceuticals industry, the study found that a moderate degree (not too low or high) of technology base diversity between alliance partners contributes more to R&D alliance performance. Similarly, there was also an inverted U-shaped relationship between R&D process experience diversity and alliance performance; too much diversity in R&D process experience may increase the likelihood of partner opportunism, and therefore negatively affect alliance performance. Additionally, the results showed that alliance governance mechanisms played different roles in alliance collaboration; while the contractual alliance mechanisms help reduce relational uncertainty (e.g., opportunism), the interactive mechanisms promoting a more intensive interaction between partners mitigates task difficulty and facilitates complex technology activities. These findings extend the knowledge-based view (KBV) of strategic alliance and advance research on alliance governance design.
