This paper contributes the analysis of the persistence of innovation activities, as measured by different innovation indicators and explores its past and path dependent characteristics. The study provides new insights on the role of R&D investments in innovation persistence and analyses differentiated patterns of persistence across product and process innovation, by accounting for complementarity effects between the two types of innovative behaviour. The empirical analysis is based on a sample of 451 Italian manufacturing companies observed during the years 1998–2006. Results highlight the relevance of innovation persistence. The highest level of persistence is found for R&D-based innovation activities, witnessing the actual presence of significant entry and exit barriers. Moreover, we obtain more robust evidence of persistence for product innovation than for process innovation when complementarity effects between the two types of innovation are accounted for. 相似文献

This article considers whether generic advertising lowers the differentiation among competing brands of the same good. Analytical results show that if the benefits from generic advertising from increased demand are outweighed by the costs from lower product differentiation then high–quality producers will not benefit from generic promotion. Hypotheses are tested empirically under a conditional–logit approach using retail–market sales and advertising data for the U.S. prune industry. Results from this study provide evidence that generic advertising has a slight differential effect on the perceived qualities of different brands. 相似文献

This article provides an overview of mandated commodity programs in California, and summarizes and interprets existing evidence on their economic impacts. The analysis draws upon the recent book edited by the authors: The Economics of Commodity Promotion Programs: Lessons from California . New York: Peter Lang Publishing, April 2005. The book documents the institutional arrangements, summarizes the history of recent litigation, and presents the results of a number of benefit–cost studies of mandated commodity programs in California. The overwhelming conclusion from the studies reported in the article is that the programs have been very profitable for California's agricultural producers. 相似文献

This article explores demand-enhancing check-off programs and how such programs may influence both private programs as well as industry market structure. Under duopoly, a firm may increase its sales through privately funding product quality improvements. However, such endogenous sunk costs may also be used to exclude a rival. Industry-funded check-off programs affect firms' strategies and can be procompetitive. The rationale lies not only in how the check-off enhancement is perceived by consumers but also in the way the check-off's crowding-out effect reduces the ability of a firm to use its private expenditures to bar a rival's market access. 相似文献

This paper examines how comparative advantages of major beef exporters changed following the 2003 bovine spongiform encephalopathy (BSE) outbreak, which significantly disrupted the U.S. beef trade until approximately 2007. Using longitudinal data on beef export values and constructed revealed comparative advantage measures, we show that while some measures of the long-run impacts of BSE on U.S. beef export competitiveness have returned to pre-2003 levels, the U.S.’s comparative advantage has not. We also examine a hypothetical scenario of no BSE event in 2003 and predict that in the absence of the BSE outbreak, the U.S. beef sector would have been increasingly more competitive by 2017 than it actually was. Long-term trade competitiveness may not simply return to normal even after a short-term disruption. 相似文献
