Entrepreneurship contributes to business dynamics in all economies, and the individual benefits of starting a business are clear. Nonetheless, access to business start-ups may not be available to all people because of resource constraints. Using a unique new data set for the United States, we examine the relative importance of three forms of resources in pursuing start-up ventures: financial, human, and cultural capital. Our analysis of the Panel Study of Entrepreneurial Dynamics shows that neither financial nor cultural capital resources are necessary conditions for entrepreneurial entry. By contrast, potential entrepreneurs gain significant advantages if they possess high levels of human capital. Specifically, advanced education and managerial experience are significantly positively associated with entrepreneurial entry. Our findings suggest that attempts at entering entrepreneurship, at least in the short-term, may be increasing, as opportunities to acquire human capital are becoming more widespread. 相似文献

This paper focuses on an unexplored dimension of fund managers’ timing ability: Market-wide tail risk implied by information in options markets. Constructing the option-implied tail risk, we investigate whether hedge fund managers can strategically time the tail risk through adjusting their exposure to changes of it. Using an extensive sample of equity-oriented hedge funds, we find strong evidence of tail risk timing ability of hedge fund managers. Furthermore, tail risk timing ability brings significant economic value to investors. Top-ranked funds outperform bottom-ranked funds by 5–7% annually after adjusting for risk factors. Our results are robust to various robustness checks. 相似文献

Based on construal level theory, this research addresses the moderating role of an individual's psychological distance towards a disease in the effectiveness of advertising messages framed by two distinctive construal level terms (high-level and low-level). In Experiment 1, two different disease types (bronchitis/distant disease vs. influenza/proximal disease) were featured, with the result that an advertisement with high-level construal terms was more persuasive for a psychologically distant disease (bronchitis) than for a psychologically proximal disease (flu). The reverse was true for an ad framed with low-level construal terms. To replicate Experiment 1 and further test the hypothesis, in Experiment 2, the perceived distance individuals have towards one disease (cancer) was measured and used as independent variable. Consistent with the results from Experiment 1, the low-level construal messages were more effective under the psychologically close condition than the psychologically distant condition. Reverse was true for the high-level construal messages. 相似文献

The importance of aid for trade as a tool for facilitating trade, economic growth and social development has received attention since the concept was introduced in 2005. While one of the main targets of aid for trade is export diversification, reflecting the fact that the exports of many developing countries are concentrated in a small range of items, there have not been many efforts to measure the effect of aid for trade on export structure. This study, therefore, attempts to trace the relationship between aid for trade and 133 aid recipients' export structure between 1996 and 2013. Using the Herfindahl–Hirschman Index to measure the degree of export concentration, the findings suggest that total aid for trade has reduced the concentration level in the short run. In the long run, on the other hand, aid for trade has had no significant effect on export structure of recipient countries. Only aid for building productive capacity, which is one of the three categories of aid for trade, contributes to lower concentration. Yet, this change is not caused by an increase in export diversity but by the redistribution of shares of existing products of a similar sophistication level. 相似文献

This paper contributes to the home (market) bias literature where administrative or political borders limit trade across borders. Home bias is well documented at the national and subnational level. To sort out macro (e.g., location characteristics) and micro (e.g., enterprise characteristics) factors behind home bias, we use small and medium‐sized enterprise (SME) data from Vietnam. Using the fractional multinomial logit model, we find that the proportion of SME sales outside of their home markets is positively associated with enterprise size, age, number of business association memberships and the distance of SMEs' most important supplier. In contrast, the proportion of SME sales to neighbouring provinces is negatively associated with the share of SME production for final consumption. Besides enterprise‐level frictions, market characteristics matter too. The proportion of SME sales to customers in their home markets is negatively associated with home or neighbouring provinces' governance quality, while the proportion of sales to customers in neighbouring provinces is positively associated with these areas' governance quality. These suggest that good governance frees SME resources for use in selling to less familiar markets. 相似文献

Companies increasingly share the stories behind their brand's founding to engage consumers. The current studies explore how the motives that underlie business formation in founder's stories influence consumer brand perceptions. Specifically, stories that highlight self‐transcendence (vs. self‐enhancement) founder values enhance the perceived authenticity of the focal brand. We examine narrative co fidelity as a mechanism of narrative persuasion through which the audience judges whether the motives underlying character actions represent “good reasons” for action. Across three studies, we show that the values underlying a founder's motivation to start a business influence the perceived authenticity of the associated brand, and this relationship is mediated by narrative fidelity. Further, reader's personal values moderate the influence of founder's values on narrative fidelity judgments, and the relationship between narrative fidelity and brand authenticity is attenuated by a merger between the original company and another company, demonstrating a boundary condition of the observed relationships. 相似文献

Corporate social responsibility (CSR) has grown on the corporate agenda and is at the heart of today’s corporate culture. While much research has examined CSR strategies and effects, the effects of post-crisis CSR communication have received relatively little academic attention. Therefore, this paper uses two experimental studies to examine several key contingency factors that influence consumers’ responses to post-crisis CSR initiatives. Results suggest that consumers demonstrate more favorable responses when a company launches a CSR initiative congruent with the crisis issue, or when the crisis is the result of an accident rather than a transgression. Further, the congruence between the crisis issue and the pre-crisis CSR initiative moderates the consistency effects between pre- and post-crisis initiatives. Such findings should be understood by considering the mediating role of corporate CSR motives’ consumer attributions, which was evidenced in this study. This study theoretically contributes to an improved understanding of the underlying mechanism of the post-crisis CSR information process and managerially contributes to the strategic development of effective post-crisis CSR initiatives given a particular situation. 相似文献

Sequels have become a profitable strategy in the U.S. motion picture industry because of their strong name recognition. However, while the established positioning of a sequel may help insulate it from competing firms' advertising messages, its familiarity may cause moviegoers to be more easily satiated with advertising from the sequel. Therefore, this study examines how sequels differ from original concept movies in terms of their ad effectiveness. We focus our analysis on pre-launch periods, given these periods' importance in shaping the financial outcomes of motion pictures. We consider the weekly online search volume of a movie as a measure of consumer interest in it, and thus as an intermediate response to pre-launch advertising. We then develop a model that assumes ad effectiveness can decline, due to copy and repetition wearout, and increase, due to forgetting, over time. We find that copy wearout is greater for original movies, while repetition wearout and forgetting are greater for sequels. These findings suggest that sequels should allocate more in early pre-launch periods and less immediately before release, relative to originals, to maximize pre-launch consumer interest. 相似文献
