Based on the knowledge-based view of the firm, this paper analyses how alternative configurations of technological relatedness in interfirm research and development (R&D) alliances influence specific types of product innovation. A longitudinal study of pharmaceutical firms provides support for the argument that complementary alliances contribute to the development of both radical and incremental innovation. Collaborating with partners that have similar technologies only enhances incremental innovation, although its impact is curvilinear. These evidences highlight the importance of designing a suitable portfolio of R&D alliances in order to develop different innovative competences. 相似文献

Knowledge intensive services and, in particular, R&D services contribute significantly to innovation in firms. The objective of this paper is to find out which characteristics of firms explain the acquisition of R&D services and to analyse whether there are differences depending on the typology of the supplier (universities, technology centres and consulting firms). Three main conclusions emerge from the econometric estimations carried out with information from a survey of innovative firms in the region of Valencia in Spain. First, the results show that firm size and age matter in the decision to buy R&D services. Second, our results are consistent with the relevance that the literature gives to human capital in absorbing external knowledge. Third, innovation policy has a significant influence on the decision to acquire R&D services, particularly from universities and technology centres. 相似文献

Companies regard innovation as a central element of their business. However, as not all innovation types are the same, the central question is: should their announcements bring about the same effect on performance? This article analyses potential differences in firm value derived from the innovation-type announcements ‘R&;D’, ‘product’, and ‘process’, made by intensive news-generating firms such as biotech companies. The empirical application shows a significantly positive reaction to innovation announcements, with the prospect of future innovation (‘R&;D’ investment announcements) having greater impact on firm value than ‘product’ and ‘process’ innovations. Firm experience also acts as a moderator in this innovation–performance relationship, which is particularly relevant for entrepreneurs who need to develop and send credible signals indicating the value of the firm's intangible assets to the market. 相似文献

This article provides a theoretical reflection on the documentary Selling Tragedy, which relates to the commodification of Ground Zero. It discusses the theoretical framework that has inspired our understanding of this place, and the methodological choices that have informed our ways of filming and editing it. This account explores the extent to which the documentary results from iteration between research, filming, screening, filming again, and editing. It leads to a discussion of the particularities of film‐making, and culminates in a call for the recognition of the film as means of entering academic debates. 相似文献

ABSTRACT In Chile the milk consumption has maintained between 124 and 134 Ls per capita since 1996. To determine the attitude and willingness to pay for national and store brands of fluid milk in the south of Chile, a survey of 400 people was conducted. A conjoint analysis determined that the consumers experienced a positive reaction toward two national brands (traditional and those emergent in the market) and expressed negative reaction to a store brand. The consumers were determined to pay lower prices in relation to the market value for the store brand and higher prices for national brands. 相似文献

This article analyzes how the public regulation of food safety influences a firm's strategic behaviour in a food chain. In this context, we provide an original theoretical framework to show how, regardless of the level of standard, food safety regulation may have unexpected harmful effects. Namely, the level of compliance costs alone cannot explain the producer exclusion due to a high level of standard. We highlight how upstream producers' involvement in the market also depends on the strategic interest of the downstream firm to remunerate their compliance process. Finally, we show how the actual level of risk does not necessarily decrease when the standard is reinforced. 相似文献

In companies where excellence in logistics is decisive for the outperformance of competitors and logistics has an outspoken role for the strategy of the firm, there is present what we refer to here as a “logistics-based business model.” Based on a multiple case study of three Nordic retail companies, the purpose of this article is to explore the characteristics of such a logistics-based business model. As such, this research helps to provide structure to logistics-based business models and identifies a way forward for companies for whom logistics and distribution are a major concern for the overall strategy of the firm. 相似文献

AbstractRetailers wish to expand their standard private label (PL) adopting a multi-tiered portfolio. We study the effects produced by the introduction of two new PLs quality-tiers (economy and premium) on the market share of various national brands (NB; premium-quality and second-tier) and the standard PL. This study proposes a model that accommodates three effects (similarity, attraction, and compromise) for understanding how the introduction of economy and premium PL may affect market incumbents. This study also analyzes the effects of introducing new PL quality-tiers for customer segments. Our results indicate that when economy and premium PL are introduced in the market, the choice probability of standard PL decreases, especially for high purchase quantity customers and PL loyal customers. In addition, introduction of a premium PL decreases the choice probability of second-tier NB and premium-quality NB, especially for PL loyal customers and high purchase quantity customers. 相似文献

ABSTRACTFor media planners to combine multiple media across platforms to maximize synergy is a critical challenge within integrated marketing communication. For this study, in-depth interviews were conducted with experienced media specialists in leading agencies to explore how they integrate different out-of-home advertising media platforms in IMC strategies. The feedback of these experts was then used to propose a model of strategies to enhance synergy within out-of-home advertising campaigns. This model is a first of its kind for planning out-of-home advertising media across platforms and bridges a gap in the existing literature on media synergy and out-of-home advertising media strategy. 相似文献
