Looking inside the spiky bits: a critical review and conceptualisation of entrepreneurial ecosystems
The concept of entrepreneurial ecosystems has quickly established itself as one of the latest ‘fads’ in entrepreneurship research. At face value, this kind of systemic approach to entrepreneurship offers a new and distinctive path for scholars and policy makers to help understand and foster growth-oriented entrepreneurship. However, its lack of specification and conceptual limitations has undoubtedly hindered our understanding of these complex organisms. Indeed, the rapid adoption of the concept has tended to overlook the heterogeneous nature of ecosystems. This paper provides a critical review and conceptualisation of the ecosystems concept: it unpacks the dynamics of the concept; outlines its theoretical limitations; measurement approaches and use in policy-making. It sets out a preliminary taxonomy of different archetypal ecosystems. The paper concludes that entrepreneurial ecosystems are a highly variegated, multi-actor and multi-scalar phenomenon, requiring bespoke policy interventions. 相似文献

The article investigates whether the history of individuals’ spatial relocation has an impact on their propensity to perform an entrepreneurial entry and post-entry performance of firms they start. By looking at entrepreneurs in the IT services sector in Swedish non-core regions between 1991 and 2010, the article investigates the interaction between individuals’ embeddedness in local networks and their exposure to external knowledge accumulation opportunities across different geographical settings, as well as its impact on their entrepreneurial activities. The results of the analysis suggest that individuals with broad spatial relocation histories are more likely to start IT firms in non-core regions, which, in turn, may be expected to survive longer. It is, therefore, claimed that non-local knowledge accumulated through spatial relocation is an important complement to embeddedness in local networks in non-core regions. This complementarity is further related to the evolution of the IT services sector over time. 相似文献

The purpose of this paper is to show the varying effects of alliance portfolio size and heterogeneity on innovation in biotechnology firms. Previous literature has indicated that the number and heterogeneity of partners in an alliance portfolio might have positive effects on innovativeness. Yet, engaging in multiple and heterogeneous collaborations also raises managerial costs and complexity levels disproportionally, potentially causing detrimental performance effects. Analysis of a unique panel dataset suggests that engaging in many alliances generally has a positive influence on a firm’s innovation output. Furthermore, maintaining diverse alliance portfolios and a high extent of alliancing jointly affects a firm’s innovation output ?negatively. By additionally showing that younger firms benefit disproportionally from both alliance portfolio diversity and size, this study provides a more nuanced view of alliancing effects. 相似文献

A common dilemma a consumer faces during product return pertains to the decision of exchanging the product or obtaining a refund. This issue becomes even more salient for durable goods, when the initial purchase involves complementary products from different categories. This research examines consumer’s trade-off decision between returning and keeping complementary products by exploring various retail actions (using umbrella branded products (UBP)) and customer characteristics. We also investigate the trade-off between product exchange and refund when consumer returns a product. We find interesting extensions to past research wherein UBP are returned less and result in greater exchange than refund. Furthermore, an interesting caveat is that higher degree of complementarity between UBP intensifies the impact of various factors on exchange as opposed to refund of products. Implications for retail managers and sales teams are explored. 相似文献

We investigate different procedures to set prices in designs for choice-based conjoint analysis using the mixed logit model which captures latent consumer heterogeneity. Besides discrete attributes, we include a linear price term in the deterministic utility function thereby treating price as continuous variable. We consider two different price intervals and several price sets which contain either two or three prices. We compare these alternatives to set prices by simulating choices for different constellations on the basis of the mixed logit model. Furthermore, we generate ten designs simultaneously instead of just one. Using these simulated choices, we estimate the parameters of the mixed logit model in the next step. To reduce the needed sample size and computation time caused by accounting for latent consumer heterogeneity, we apply Halton draws and set a minimum potential design for prior draws. ANOVA with root mean squared error between estimated and true price coefficient values of individual consumers as dependent variable shows that using more extreme prices as interval bounds and one intermediate price positioned to the right of the interval performs best. 相似文献

There are conflicting predictions in the literature about the relationship between FDI and entrepreneurship. This paper explores how foreign direct investment (FDI) inflows, measured by lagged cross-border mergers and acquisitions (M&A), affect entrepreneurial entry in the host economy. We have constructed a micro-panel of more than two thousand individuals in each of seventy countries, 2000–2009, linked to FDI by matching sectors. We find the relationship between FDI inflows and domestic entrepreneurship to be negative across all economies. This negative effect is much more pronounced in developed than developing economies and is also identified within industries, notably in manufacturing. Policies to encourage FDI via M&A need to consider how to counteract the prevailing adverse effect on domestic entrepreneurship. 相似文献

This paper analyzes the importance of individual and place characteristics on the selection into self-employment in Chile. Following a structural and multilevel empirical approach, we test whether both sets of variables explain the variation of individual wages, self-employed earnings, and the propensity of being in independent work. The results indicate that while most of the variation in these three outcomes is explained by individuals’ traits, place-related variables account for a non-negligible share of spatial variation. Second, as suggested by occupational choice theories, the propensity of being in self-employment positively correlates with larger expected earning differentials, but only in the case of employers. This, along with other results, suggests that while employers seem to choose their occupational status, own accounts in Chile seem to respond to factors pushing them into self-employment. 相似文献

In this paper, we study the determinants of the spread charged by banks under a UK policy intervention scheme, aimed at supporting access to the credit market for small firms through guarantee backed loans. We exploit a unique dataset containing data on 29,266 guarantee backed loans under the UK SFLG scheme over the period 2000 to 2005. Results suggest that lower spreads are offered for loans of larger amounts and higher durations, for service firms, for larger firms, and for those located in the most advanced regions. Higher spreads are applied to high-tech manufacturing firms and to loans issued for working capital purposes. We also find that the presence of other extant debt is associated with a relatively higher spread and that this effect is especially significant for the subset of firms that have reached a maximum debt capacity based on collateralized assets. Further, we also find that the higher the incidence of the publicly guaranteed debt over the total amount of outstanding loans, the lower, on average, the spread. However, an increase in the guaranteed coverage leads to a contraction in the spread only for loans aimed at covering working capital needs rather than investments. 相似文献

With 40% of the world able to access the internet, online marketplaces provide the small entrepreneur with a hitherto incomprehensible opportunity to reach a global audience with very low barriers to entry and low risk. Yet, academic research has not studied the factors unique to online businesses that affect their long-term survival. This study is the first of its kind that does so using data gathered from eBay’s feedback system in 2004, 2009, and 2013. The results present data on the rate of discontinuance of eBay ventures. Further, a logistic regression analysis suggests that unique factors such as venture size, age, and feedback reputation positively influence the likelihood of long-term survival of an eBay venture. Based on these results and the ensuing discussion, implications for researchers and practitioners are provided. 相似文献

This study introduces the concept of attractiveness similarity, empirically examines its main effect and whether it moderates the effect of endorser attractiveness on consumer responses to advertising. The results show a positive main effect of attractiveness similarity over and above the mere effect of endorser attractiveness. In addition, a consistent moderating effect of attractiveness similarity on the effect of endorser attractiveness emerges: attractiveness similarity buffers against the less positive effects of lower levels of endorser attractiveness (i.e., it compensates for lower levels of endorser attractiveness). Overall, these findings reveal attractiveness similarity as a new variable in endorser advertising, which has important managerial implications. Advertising campaigns employing averagely attractive endorsers should pay special attention to attractiveness similarity. 相似文献
