We study the impact of ambiguity on the pricing and timing of the option to invest. There is a funding gap to undertake the investment, which is covered by entering into an equity-for-guarantee swap. Our model predicts that the more ambiguity-averse the agents, the less the option value, the later the investment and the higher the guarantee cost and the leverage. If the entrepreneur is more ambiguity-averse than the insurer, the investment threshold slightly rises as the perceived ambiguity increases, and on the contrary, if the entrepreneur is less ambiguity-averse than the insurer, the investment threshold increases sharply as the perceived ambiguity rises.  相似文献

There is ample evidence that distance has a strong negative effect on migration. Despite its significance in migration decisions, scholars rarely explore the migration distance effect deeper than the first level of interpretation derived from the simple neoclassical theory of migration. This study revisits the migration distance effect in the spirit of Knightian distinction between risk and uncertainty. To this end, this study attempts to construct estimates of the risk premium migrants are willing to pay to avoid the risk associated with migration distance. The results show that the magnitude of the distance effect is not rationalized by risk aversion in the Arrow–Pratt sense (Arrow, 1965, The theory of risk aversion, Yrjo Jahnssonin Saatio, Helsinki, Finland, 90; Pratt, 1964, Econometrica, 32, 122). In particular, the risk premium demanded by distant rural residents is unjustifiably higher compared with that of those living closer to urban areas in their migration decisions. The results suggest that the migration distance effect is analogous to the equity home bias puzzle and the Ellsberg paradox in that the assumption of subjective expected utility can lead to seemingly irrational human behaviors. Some of the findings in this study shed light on the role of subjective aspects such as perception, confidence, and pessimism in migration decisions, which have been neglected in the literature.  相似文献

Combining role theory with theories on hindrance stressors and intragroup conflict, we develop a model of the attitudinal and behavioral consequences of new employee orientation in hospitality organizations. We test hypotheses about main and mediated effects in this model, using data from a sample of 156 recently hired hospitality interns and applying a longitudinal approach, with data collection shortly after organizational entry and several months later. Results suggest that employee orientation is negatively related to two hindrance stressors: role ambiguity and role conflict. Role ambiguity predicts a range of attitudinal outcomes and the relationship is partially mediated by relationship conflict. In addition, role ambiguity is negatively related to task performance. Role conflict predicts hospitality employees’ job attitudes and this relationship is fully mediated by relationship conflict. We discuss important theoretical and practical implications of these findings for human resource management in hospitality firms.  相似文献

Some governments seem ambivalent towards economic crime because, on the one hand, there are adverse effects on competition and legal businesses; on the other hand, there are benefits through (shadow) employment and income in less-developed areas, as well as benefits through relations of political clientage. We focus on counterfeiting and its economic effects on trade in Italy during the economic crisis. Using a newly built regional dataset and a dynamic panel model, we find evidence of the dual impact of counterfeiting. The production (and exchange) of fake goods depresses the legal market that relies on intellectual property rights but supports shadow-economic activities for the benefit of illegal workers, criminal organisations, and political clientele. We show that the negative effects outweigh the positive effects.  相似文献

Managing work-family interface has been a key issue for hospitality employees. By integrating the literature on thriving at work into the work-family enrichment model, this study proposes taking charge as a resource-generating behavior that employees could undertake to enrich their family life. Using data collected on two occasions from frontline employees and their supervisors in a hotel in China, we find that those who take charge are more likely to experience thriving at work, which helps them improve the quality of their family life. Furthermore, working under a leader facing high role ambiguity augments this relationship. The study findings advance current work-family enrichment literature, and also carry important practical implications for promoting employees’ work-to-family enrichment in the hospitality sector.  相似文献

Abstract

Organizational psychologists and HRM scholars have long argued that prosocial organizational behaviors enhance organizational performance. However, prosocial behaviors are motivated by both self-interested and altruistic intent. Moreover, some have recognized that the factors that encourage shifts between egoistically and altruistically motivated prosocial behaviors may result from inherent tensions between individual disposition and situational contexts. As such, this study draws from literature examining prosocial behavior to evaluate whether work situations with clear task expectations dampen the extent to which prosocial personal dispositions diminish egoistically motivated prosocial behavior. Findings from a series of structural equation models reveal that altruistic dispositional traits diminish egoistic motives for engaging in one specific prosocial behavior, whistle-blowing. However, findings also reveal that work situations characterized by clear task expectations dampen the negative effect of altruistic dispositions on egoistically motivated whistle-blowing. Our findings imply that managers can adjust organizational contexts to capitalize on the enhanced benefits resulting from altruistically motivated prosocial behaviors.  相似文献

Evolutionary Systems Design (ESD) is a universal general problem solving, formal modeling, design framework for purposeful complex adaptive systems (PCAS) and processes, i.e., task-oriented group processes. These processes constitute policy making, group decision, negotiation, and multiagent problem solving with human and/or artificial agents. ESD is also a framework for computer group support systems (GSS) that support these processes. The ESD general framework can be applied to define and solve specific problems. In this article the ESD framework is presented and illustrated by example. The article provides background for ESD computer implementations discussed in two other related articles (Lewis and Shakun 1996; Bui and Shakun 1996).  相似文献

Innovation contests allow firms to harness specialized skills and services from globally dispersed participants for solutions to business problems. Such contests provide a rich setting for operations management (OM) scholars to explore problem solving in global labor markets as firms continue to unbundle their innovation value chains. In this study, we examine the implications of specific types of diversity in innovation contests on problem-solving effort and success. First, we conceptualize diversity among contestants in terms of national wealth (measured as gross domestic product per capita (GDPP) adjusted for purchasing power parity) and national culture (measured using the culture dimensions of performance orientation and uncertainty avoidance) and examine how such factors influence problem-solving effort. Next, we examine how differences between contestants and contest holders in terms of the above factors influence contest outcomes. Using data from a popular online innovation contest platform and country-level archival data, we find that contestants from countries with lower levels of GDPP are more likely to exert greater problem-solving effort compared to other contestants. With regard to national culture, we find that performance orientation and uncertainty avoidance have positive and negative effects, respectively, each of which weakens with increasing levels of GDPP. Finally, our analysis provides evidence of homophily effects indicating that contestants who share greater similarities with the contest holder in terms of national wealth and national culture are more likely to be successful in a contest. We discuss the implications of the study's findings for contest holders and platform owners who organize innovation contests, and for emerging research on innovation contests.  相似文献

Researchers have spent substantial effort to identify factors influencing pesticide use intensity. However, few studies have compared the relative importance of these factors. This study examines four categories of factors that potentially influence farmers’ pesticide use decisions by evaluating incentivized experiment data, farm survey data, and remote sensing data in China. Our results suggest that land diversification has the largest effect on farmers’ pesticide use. Compared with the most rice-intensive landscape type, less rice-intensive systems cause farmers to spray less on middle rice. Heavy pesticide use intensity is associated with land fragmentation as small-scale farms still dominate crop production. Farmers’ integrated pest management knowledge has significant effects on pesticide use. We also find that loss and ambiguity preferences, rather than risk preferences, are more likely to affect pesticide use intensity.  相似文献
