女性社会网络关系与创业融资劣势

随着“大众创业、万众创新”相关政策深入实施,利用互联网众筹等新融资平台为创业团队募集资金,已成为创业融资的重要手段。然而,在网络众筹平台上,女性领导者主持的创业项目在数量、融资额度或成功机会上均远低于男性领导的创业项目。女性是否存在互联网创业融资瓶颈,何种原因导致上述劣势存在,成为理论界亟需解决的重要问题。为此,从社会嵌入理论出发,基于互联网众筹平台1 517个创业项目,利用PSM及OLS方法研究发现,女性在社会网络相关条件强度和社会网络对创业融资影响两方面都存在创业劣势,进而确定了女性创业者融资劣势的来源,并提出了相关建议。     

Trade, demand spillovers, and industrialization: The emerging global middle class in perspective

In this paper, we investigate international demand spillovers brought about by a global middle class and their impact on trade patterns and industrialization. We propose a multi-industry and two-country trade model featuring demand complementarities propagating increasing returns across industries and national boundaries. We show how the international extent of demand spillovers depends upon asymmetries in domestic income distribution, labor efficiency, and labor force size; that is, on the global distribution of real income.

Entrepreneurial Narratives in Sustainable Venturing: Beyond People,Profit, and Planet

Sustainable venturing, the process of starting a new sustainable enterprise, has been studied extensively through the triple‐bottom‐line lens. The narratives employed by sustainable entrepreneurs, however, have proven to be more complex and diverse. In this paper, we set out to inductively explore the narratives underlying sustainable venturing. We conducted an interpretative analysis to elucidate how these entrepreneurs perceive, think about and give meaning to sustainability as they develop their ventures. Findings allow for an expansion of the role of narratives in business venturing toward a more sophisticated conceptualization grounded in how actual entrepreneurs experience and enact sustainability in the context of their ventures.     

Bank-Affiliated Mutual Fund Managers' Trading Patterns of Parent Banks' Stocks: International Evidence

The authors explore factors influencing bank-affiliated funds' decisions to increase their holdings of parent banks' stocks by analyzing survey evidence from 113 fund managers from the United States, Canada, Great Britain, Spain, and Poland. The results suggest that the propensity to buy the controlling banks' equity among financial professionals at the time of the stock market meltdown was shaped rather by the individual taste for their assets as consumption goods than by external pressures by direct superiors or the parent banks' management. Additionally, this predisposition was influenced positively by the fund managers' tendency to herd and fund participants' expectations as well as managers' sensitivity to eventual losses and previous work experience in the owning banks. The major investment segment represented by the fund also seems to be important, with an increasing level of risk acting as the denominator. Overall, this study extends the understanding of behavioral factors in bank-affiliated funds' allocation decision making.     

Fragmented networks and transnational entrepreneurship: Building strategies to prosper in challenging surroundings

Transnational entrepreneurship studies highlight the importance of personal profiles, institutions, and networks in creating and succeeding in this type of entrepreneurship. Even so, less is known about migrants whose networks are fragmented and closed, facing challenging environments at home and abroad. This paper aims to study the attributes of transnational entrepreneurs with small and fragmented networks, from post-conflict environments, who can perform an important role in the socioeconomic development and internationalization level of their countries of origin due to the cross border mobilization of resources they encourage. For that reason, the specific case of Colombian transnational entrepreneurs who have been able to overcome those obstacles with their transnational business is analyzed with the intention of understanding how they manage those shortcomings when engaging in transnational entrepreneurship. In aiming to obtain a deeper understanding of their characteristics, similitudes, differences, and motivations, the research uses multiple case studies. The main findings suggest that transnational entrepreneurs form purposeful–strategic networks to compensate their lack of amalgamated social systems, and that they have special qualities that distinguish them from other Colombian migrants and transnational entrepreneurs. Moreover, Colombian transnational entrepreneurs focus their business in the international market, using strategically their knowledge of both the local and foreign environment, while their main interest to do so is not altruistic but business oriented. Governments from post-conflict countries should promote transnational entrepreneurship while facilitating network formation and institutional trust through diverse strategies. Finally, implications for further research are drawn.
