This special issue focuses on entrepreneurship, innovation and enterprise dynamics, as these key components of any prospering economy are at the heart of the current policy discussion. It gathers the latest national and comparative cross-country evidence about: new business venture formation and the role of framework conditions in fostering entrepreneurial activities; the determinants and outcomes of firms’ innovative activities and, more generally, of business and innovation dynamics; and the determinants and patterns of post-entry firm growth performance. The contributions synthesised in this introductory piece all rely on sound micro-level data and robust econometrics and propose novel findings that are relevant for policy making. Among them, that risk aversion encourages individuals to invest in balanced skill profiles, making them more likely to become entrepreneurs; and that while micro firms may grow when they are young, they are less likely to do so when old.  相似文献

Founders of hybrid ventures encounter organizational tensions that can compel compromise in both their organizations' and their own personal values. Such compromises may, in turn, undermine founders' identification with their ventures. In a multi-case study analysis we examine why social entrepreneurs differ in their responses to organizational tensions, both at the firm- and individual-level, and how such differences relate to their venture identification. Specifically, our findings reveal that strategic decisions made in the context of values-based complexity are often accompanied by concerns regarding founder authenticity—that is, judgments about the alignment between founders' actions and the commitments or responsibilities associated with their identities as entrepreneurs. Yet, because founders differ in the basis from which they seek to maintain such alignment, these differences shape both hybridity management and subsequent venture identification. By unpacking such differences, our findings contribute new theory, bridging recent scholarship on founder authenticity with longstanding research on organizational identification and hybrid organizing.  相似文献

Emerging markets offer tremendous growth opportunities for firms. While established multinational firms typically focus on premium segments in emerging markets, they often fail to leverage additional growth opportunities in so‐called good enough or low‐income segments in emerging markets. Customers in these low‐income markets have substantially different requirements and are very price sensitive. Theoretical and case‐based research suggests that innovating for these low‐income segments in emerging markets differs significantly from innovating for premium or traditional Western markets. We argue that tapping successfully into low‐income segments in emerging markets requires the development of new products that meet the low price expectations while at the same time offering also value to customers in these segments. We refer to these new products as affordable value innovations. We analyze the antecedents of affordable value innovation for emerging markets. We draw on institutional theory to derive three potentially relevant antecedents of affordable value innovation for emerging markets. These are bricolage, local embeddedness, and standardization. We test our hypotheses using multiple informant data from 47 multinational corporations involving 103 innovation projects that target low‐income customers in emerging markets. Our empirical analysis shows that all three antecedents have significant effects on the level of affordable value innovation: while bricolage and local embeddedness are positively related to the level of affordable value innovation, standardization has a negative impact. We also examine the relationship between the level of affordable value innovation and performance. We find evidence for our basic assumption that a firm's capability to develop and launch affordable value innovations is key to success in emerging markets. It indicates that a firm's investments in affordable value innovations for emerging markets pay off financially. Finally, a cross‐regional comparison of our data shows that the key findings on antecedents of affordable value innovation and its impact on performance do not vary across various emerging markets. Overall, our findings offer important implications for research on and the practice of innovation for low‐income segments in emerging markets.  相似文献

Emergent research has examined the antecedents to using information technology (IT) in the new product development (NPD) process and the impact of IT on NPD performance. Based on the resource‐based view (RBV) of the firm, this study hypothesizes that particular resources create IT capabilities that significantly enhance NPD outcomes. More specifically, this research extends previous work by investigating whether three complementary resources, namely an executive champion for IT, global engagement, and organizational innovativeness, influence IT capabilities (IT use frequency and IT replacement frequency), which in turn affect NPD outcomes (NPD task proficiency and NPD performance). To test the conceptual model, survey data were collected from 220 NPD and IT managers in a variety of large Japanese firms. The results show that an executive champion for IT and global engagement are predictors of both IT tool use and replacement frequency while organizational innovativeness contributes only to IT tool replacement frequency. The results also indicate that both IT tool use and replacement frequency have a positive effect on NPD task proficiency, which improves NPD performance. This research contributes to the literature by adding understanding of the role of IT in NPD at the firm level in four ways. First, it examines particular organizational complementary resources and their relationship to IT capabilities. Second, it examines the RBV and IT in the context of NPD, an important business process. Third, it measures IT usage in a more granular fashion (i.e., IT tool use frequency and IT replacement frequency) rather than simply IT usage as a dichotomy. Finally, through testing the proposed model with data collected from Japanese firms, this study provides empirical evidence from an Asian country to answer the call for more NPD research to be conducted in countries other than North American and Western European contexts. The findings of the study also provide implications for managers. Importantly, they indicate that an executive level champion for IT is a key influencer in facilitating IT usage and replacement, and likely can help generate awareness of and support for greater IT investments so the firm can create IT capabilities for effective NPD.  相似文献

We describe the quantitative modeling techniques that are used in horizontal merger review for the evaluation of unilateral effects, and discuss how the 2010 Horizontal Merger Guidelines helped legitimize these methods and motivate scholarly research. We cover markets that feature differentiated products pricing, auctions and negotiations, and homogeneous products, in turn. We also develop connections between quantitative modeling and market concentration screens that are based on the Herfindahl-Hirschman Index (HHI).

We approximate probabilistic forecasts for interval-valued time series by offering alternative approaches. After fitting a possibly non-Gaussian bivariate vector autoregression (VAR) model to the center/log-range system, we transform prediction regions (analytical and bootstrap) for this system into regions for center/range and upper/lower bounds systems. Monte Carlo simulations show that bootstrap methods are preferred according to several new metrics. For daily S&P 500 low/high returns, we build joint conditional prediction regions of the return level and volatility. We illustrate the usefulness of obtaining bootstrap forecasts regions for low/high returns by developing a trading strategy and showing its profitability when compared to using point forecasts.  相似文献

Abstract:

This article is a response to two crucial ideas about progressive institutional change: the first is J. Fagg Foster’s principle of “minimal social dislocation,” which asserts that socio-economic changes should be implemented gradually, to avoid unraveling the social fabric of the community; the second is Karl Polanyi’s principles of redistribution of rights and powers by relevant authorities and reciprocity, a symmetrical and highly personalized exchange system, which is likewise a protective mechanism that society employs against anonymity and disintegration brought about by unregulated market. Using lessons learned in the thirty-year transition to market in post-Soviet countries, this article argues that to commence progressive institutional change in the honesty- and transparency-resistant cultures of former Soviet states, impersonal exchange and impartial rule of law must be given far greater weight than personalization of contacts and continuation of cultural traditions.  相似文献
