This paper studies the combined effect of affiliation with prestigious universities, underwriters, and venture capitalists on the valuation of biotech ventures at IPO and their post-IPO performance. We argue that affiliation to a prestigious university provides the affiliated firm with a quality signal in the scientific domain. The pure quality signaling effect of the affiliation is isolated from the substantive benefits it provides by performing a difference-in-difference approach based on the scientific reputation of scientists in firms' upper echelons. The signal is stronger the weaker is the scientific reputation of scientists of the focal IPO-firm and is additive to those provided by prestigious venture capitalists and underwriters. Results for a sample of 254 European biotech ventures that went through an IPO between 1990 and 2009 confirm our predictions. 相似文献

The economics and management literatures pay increasing attention to the technological, competitive, and institutional environment for entrepreneurship. However, less is known about how context influences the judgment of entrepreneurs. Focusing on the emerging judgment‐based approach to entrepreneurship, we argue that economics can say much about how the organizational, market, and institutional context shapes entrepreneurial judgment. We describe entrepreneurs as individuals who deploy scarce, heterogeneous resources to service customer preferences at a profit. Because of uncertainty, this process is essentially experimental, and context influences the experimental process. Thus, entrepreneurs will seek to design the internal organization of the firm so that it facilitates internal experimentation. Moreover, the market or task environment determines the need for experimentation (e.g., how fast do consumer preferences change, how does technology evolve, which assets are available at which terms, etc.). Finally, the institutional environment influences, for example, the transaction costs of acquiring and divesting assets as firms adjust their boundaries through ongoing commercial experimentation. 相似文献

基于253家浙江省众创空间的微观数据,文章在运用连续距离的测度方法测算众创空间集聚水平的基础上,采用零膨胀负二项回归等方法实证分析众创空间集聚的影响机制。研究发现,众创空间的地理分布存在显著的区域差异,主要分布在杭州和宁波市辖区,选址具有明显的集聚特征。回归结果显示,区域创新能力和生态环境均对众创空间的地理集聚具有促进作用,但两者之间存在明显的替代效应;尽管不能直接促进众创空间的集聚,政策引导与创新能力之间具有较显著的互补效应。据此,文章从培育创新能力和优化创新激励等方面提出了政策建议。 相似文献

This study examines the use of Management Control Systems (MCS) in travel and tourism start-ups. The study empirically examines 176 European tourism start-ups; data are collected via an online survey of start-up CEOs, and supplemented by financial statements of early-stage tourism firms. The results show that travel and tourism start-ups use formal systems for management control. We observe a relationship between the usage of these systems with specific internal and external environment characteristics. Finally, the results show that the historical financial performance of travel and tourism start-up firms affects MCS usage. 相似文献

Recent researches have shed light on the effect of cognitive ability on economic decision-making. By measuring cognitive ability applying Raven's progressive matrix test, we obtain two significant results that this effect affects decision-making in two types of experimental ultimatum games. First, the higher the cognitive ability, the larger the amount a sender offers when the offer is smaller than or equal to the half split. Second, the higher the responders’ cognitive ability, the smaller the offer they accept, when they accept it or not with the strategy method. This study not only finds new factors that affect decision-making in experimental ultimatum games, but also provides more evidences that cognitive ability influences economic decision-making. 相似文献

Using panel data from 282 Chinese cities from 2003 to 2015, we estimate the impact of venture capital (VC) on innovation, employment, and payroll in metropolitan areas. Controlling for endogeneity, VC investments are significantly positively related to metropolitan innovation, employment, and payroll in a fixed effects panel regression and dynamic GMM estimation. Using the number of IPOs (Initial public offerings) in the city as an instrumental variable to again control for endogeneity, VC remains significant. Our results show that VC is significantly contributing to the metropolitan economy as a whole by supporting innovation, creating jobs, and generating wealth in the local cities. 相似文献
