Investors’ aspirations toward social impact: A portfolio-based analysis
Full text linkIn the last ten years, we have witnessed a proliferation of investors claiming blended value strategies, i.e., pursuing both economic and social returns in their investments. Aside from this rush for self-selecting in a blended value finance context, we still do not know to what extent the investors’ claims actually reflect investment decisions. Evidence suggests that, in some cases, such investors tend to maximize the social performance over the financial performance; in some others, the effect is reverted, but literature currently lacks studies aligning the analysis of the investment decisions with the investment portfolios. Yet, it is still unclear whether blended value investment decisions are enacted as a result of investors’ deliberate strategies and what influences this relationship. In this paper we tackle this issue, analyzing the extent to which investors’ finance firms pursuing goals aligned with their strategic aspirations. Specifically, adopting a Fractional Logistic Regression model, we test the effect of investors’ aspirations toward social impact on the extent to which their investees (i.e., the portfolio of firms in which they invest) pursue social returns. Results suggest the existence of a positive and significant investor–portfolio alignment effect (i.e., the higher the investors’ aspirations toward social impact, the higher the number of investees with higher social aspirations). Yet, this effect is influenced by contingencies at both investor and portfolio levels. Investors with strong aspirations toward social impact that: (i) invest in countries with high levels of social inequality, and (ii) are located in countries that support social progress and maximize, in their portfolios, the presence of businesses pursuing social impact. We discuss implications for future researchers, policymakers and practitioners
Attention to Exploration: The Effect of Academic Entrepreneurship on the Production of Scientific Knowledge
Full text linkWe study how becoming an entrepreneur affects academic scientists' research. We propose that entrepreneurship will shift scientists' attention away from intradisciplinary research questions and toward new bodies of knowledge relevant for downstream technology development. This will propel scientists to engage in exploration, meaning they work on topics new to them. In turn, this shift toward exploration will enhance the impact of the entrepreneurial scientist's subsequent research, as concepts and models from other bodies of knowledge are combined in novel ways. Entrepreneurship leads to more impactful research, mediated by exploration. Using panel data on the full population of scientists at a large research university, we find support for this argument. Our study is novel in that it identifies a shift of attention as the mechanism underpinning the beneficial spillover effects from founding a venture on the production of public science. A key implication of our study is that commercial work by academics can drive fundamental advances in science
The influence of entrepreneurs’ immigrant status and time on the perceived likelihood of exporting
Full text linkWe contribute in this paper to the scant literature on the factors and conditions influencing the development of different perceptions of potential international opportunities for immigrant and native entrepreneurs in the pre-internationalization phase. Specifically, we investigate what factors influence the perceived likelihood entrepreneurs have of exporting. Building on entrepreneurial intentions and opportunity-based entrepreneurial processes, we propose a cognitive account of perceived likelihood of exporting based on entrepreneurs’ perceptions of the desirability and feasibility of export opportunities. We investigate how the immigrant status (i.e., individual characteristics) and time (i.e., contextual factors) influence the relationship between the desirability and feasibility of exporting, and entrepreneurs’ perceived likelihood of exporting. We employ an experimental design on a matched-pair sample of 108 native and immigrant entrepreneurs in domestic technology-based firms. The results are a unique account of the cognitive antecedents of the perceived likelihood of exporting under different temporal conditions, comparing immigrant and native entrepreneurs. We discuss theoretical and practical implications
The effectiveness of university regulations to foster science-based entrepreneurship
Full text linkIn this study, we analyze the effect of the introduction of university regulations supporting academic entrepreneurship. Using a sample of 611 companies spun-off from the 64 Italian Science, Technology, Engineering, Mathematics and Medicine (STEMM) universities between 2002 and 2012, we show that university regulations in support of academic entrepreneurship have a positive effect on the creation of academic spin-offs. Nevertheless, their effectiveness is conditioned by specific contingencies. First, the characteristics of university departments influence the positive effect of the regulation: in some cases, there is a substitution effect rather than a complementary one. Second, the design of the regulation impacts the decisions of academic staff regarding whether to start a new venture. Finally, the effect of the regulation is maximized four years after its introduction and then becomes less effective. This paper contributes to the debate on the evaluation of policies supporting science-based entrepreneurship
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
