We investigate the relationship between entrepreneurial capacities and firm performance. More specifically, we investigate the effects of radical innovation and learning orientation on business performance. We test the effects of entrepreneurial orientation on learning orientation and radical innovation. The results suggest that radical product innovation and companies' orientation to learn have a positive effect on organizational performance. Additionally, we find that entrepreneurial orientation positively influences a firm's capability to learn and innovate. Our findings also show a direct effect of learning orientation on radical innovation, which means that companies with a higher proclivity to learn are more likely to create products and processes, representing a major departure from the state of current knowledge.

We study the determinants of the survival of new export products of multi‐product firms. We use micro‐level data from Chile to estimate linear fixed‐effects and non‐linear survival models to show that a measure of “distance” between a firm's new export and its previous export basket is a negative and significant determinant of the survival of the new export, especially during its first year. Our interpretation of this finding is that exports further away from firms’ core competences have lower chances of survival in exports since it is more difficult for firms to achieve competitiveness in them. Our results suggest that country‐level diversification, at least through existing firms, should be gradual.  相似文献

The stability of international trade networks has been investigated using the pairwise stability concept. This concept is suitable to study the formation of bilateral agreements. However, it cannot be used to determine the stability of global trade agreements. This article proposes an alternative stability concept that can be adopted to determine the stability of global agreements such as the Doha agreement. This concept is named in this paper Global Treaty Stability.  相似文献

Merger efficiencies provide the primary justification for why mergers of competitors may benefit consumers. Surprisingly, there is little evidence that efficiencies can offset incentives to raise prices following mergers. We estimate the effects of increased concentration and efficiencies on pricing by using panel scanner data and geographic variation in how the merger of the brewers Miller and Coors was expected to increase concentration and reduce costs. All else equal, the average predicted increase in concentration led to price increases of 2%, but at the mean this was offset by a nearly equal and opposite efficiency effect.  相似文献

Nightlife economic activity has emerged as a key strategy in the regeneration of historical quarters. The case of the Bairro Alto district (Lisbon) exhibits a more gradual and distinct development caused by the marginal and transgressive practices of nightlife visitors, who have resisted its gentrification for decades. Some areas in the Bairro Alto (specially the upper side) have maintained their dangerous character and marginalisation for several years, even after the 2008 urban reform programme. It is only recently, with the growing presence of Erasmus students in Bairro Alto, that the upper side has finally become safe and sanitised through leisure activities. In this article, the interplay of several social actors (foreign students, municipal authorities, night-time entrepreneurs and Erasmus organisers) explains the process of place-making regarding the new Erasmus Corner. The spatial colonisation of this spot has accelerated social cleansing of the upper side of the neighbourhood, concluding the district’s night-time pacification.  相似文献

This study examines the influence of network capability (the ability to use external relationships), information and communications technology (ICT) capability (the ability to strategically use ICT for business purposes), and financial slack (unused and uncommitted financial resources) on the innovation performance of small firms. This extends the current resource‐based view and small firm innovation management literatures by proposing the direct and interactive effects of organizational capabilities and financial slack. The results of regression analysis based on survey data from technology‐based Swedish small firms show that the three‐way interaction involving network capability, ICT capability, and financial slack influences innovation performance.  相似文献
