This study explores when wholly owned subsidiaries outperform joint ventures with local partners. In order to avoid the endogeneity problem inherent in foreign subsidiaries' operating mode decisions that might confound performance measurement, we employ the propensity score matching method, along with the difference‐in‐differences approach, and compare the performances of joint ventures turned wholly owned subsidiaries vis‐à‐vis continuing joint ventures. Based on foreign subsidiaries' financial data in China for 1998–2006, we find strong evidence that converted wholly owned subsidiaries outperform continuing joint ventures in industries characterized by high levels of intangible assets such as technology or brand, after controlling for factors that may affect the conversion decision. This finding is consistent with the prediction of transaction cost theory. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Drawing on institutional theory and innovation literature, we argue that greater regulatory and normative pressures concerning environmental issues positively influence companies' propensity to engage in environmental innovation. Analysis of environment‐related patents of 326 publicly traded firms from polluting industries in the United States suggests that institutional pressures can trigger such innovation, especially in those firms displaying a greater deficiency gap (i.e., firms polluting relatively more than their industry peers). Moreover, we find that this effect is stronger when asset specificity is high, and that the availability of resources plays different roles depending on the type of pressures (regulatory vs. normative).Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

This study examines the impact of bribery within the home country on firm exports by developing two contrasting hypotheses. On the one hand, preferential treatment resulting from government officials in exchange for bribes may promote exports by enhancing efficiency and enabling bribing firms to better compete in foreign markets. On the other hand, preferential treatment resulting from bribes may decrease exports by providing firms with more established positions within the domestic market diminishing the incentive to explore foreign markets. Adopting the three‐stage least squares method, we test these competing arguments using a sample of firms operating within transition economies. We find that bribery within the home country decreases rather than increases firm exports. The implications of our findings are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

We predict that the media reports on female CEOs as a coherent group, whereas male CEOs are treated as individuals by the media. We also suggest that the resulting investors' perceptions of group entitativity of female‐led firms may not only influence the succession event–performance relationship at the focal firm, but may also have a significant effect on the value of other female‐led companies. Results of a text analysis and an event study of appointments of female CEOs to Fortune 1000 firms provide support for these predictions. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

We propose a new way of constructing more robust technology portfolios to overcome the weaknesses of previous technology portfolios based either on the judgments of experts or on quantitative data such as patents. Instead of using historical data, the method of nonlinear forecasting enables us to forecast the future number of patent citations and accordingly, to use the forecast as a quantitative proxy for future returns and risks of technologies. Using the Black–Litterman portfolio model, we improve the accuracy of inputs by combining the future views of experts with the future returns and risks of technologies. As a consequence of this, the portfolio becomes strongly future‐oriented. With our approach, corporate managers use both experts and data more effectively to build robust technology portfolios. In particular, our method is of great help for companies launching new businesses because the method avoids heavy dependency on internal experts with little knowledge about emerging technologies. A company entering the molecular amplification instrument market is exemplified herein.  相似文献

Abstract

Confucian philosophy has traditionally had a considerable influence on many aspects of the lives of the Taiwanese people. It is therefore necessary to take this belief structure into account in order to explain Taiwanese women’s leisure perceptions and behaviours. The purpose of this study is to examine this issue. The factors that constrain women’s leisure in Taiwan are identified. These categories can be broadly termed economic, domestic, social, and cultural constraints  相似文献

Prior studies in the existing tourism literature have frequently emphasized the relatively expensive costs for drawing first‐time visitors. These studies, however, have largely failed to explain how to draw first‐time visitors to a destination. In other words, little was known regarding what destinations should do to attract first‐time visitors in an effective way. To provide more insights, this research investigated the impact of three diffusion models on attracting first‐time visitors. These models included an external influence model for impact of mass media, an internal influence model for impact of interpersonal communications, and a mixed model for impacts of both mass media and interpersonal communications. Assessing the model impact in a macroapproach for first‐time visitors to Hong Kong, empirical findings indicated that the mixed influence model provided the highest explanatory quality, with word‐of‐mouth being a dominant factor.  相似文献

The Internet and its component, the World Wide Web (WWW or Web), as well as the casino industry grew tremendously in the United States in the past decade. While there are various estimates about the future size of the Internet and the casino market, all agree that the two will continue to grow substantially. However, very few studies have discussed Internet use within the casino industry. This study reviewed 58 Class III Native American casino web sites. Content areas analyzed included introduction to the casino organization, local destination attractions, food and beverage services, accommodations, entertainment and recreation facilities, maps and directions to casinos, links to related commercial and regulatory agency web sites, and user friendliness. Web site features were evaluated based on marketing mix and principles.  相似文献

The purpose of this paper is to examine the ties between the success of a TV drama Winter Sonata, produced by the Korean Broadcasting System (KBS), and the flow of tourism into Korea. By deconstructing the Hallyu phenomenon, started in part by Winter Sonata, the study tries to determine possibilities for Korean tourism expansion. Literature reviews, tourism data, interviews with specialists, and actual pieces of feedback from Winter Sonata's Egyptian audience are referred to draw conclusions on the subject matter. Results show promising markets far beyond just Asia, touched by Hallyu, but not the opportunity to tour Korea yet. Suggestions are then made on how to help sustain Hallyu tourism and increase access to potential new travel markets, especially those in diverse Islamic regions around the world.  相似文献
