This paper investigates the implications of a technology sourcing strategy maintaining a focus on the rediscovery of old technologies. Specifically, we study the different impact exerted by old technological solutions, distinguished on the basis of their organisational and industrial origins, on the innovation value. We develop a set of hypotheses about the impact exerted by four distinct types of old technological solutions (firm core technological heritage, firm lateral technological heritage, competitors’ technological heritage and others’ technological heritage) and test them on a sample of 1189 biotechnology patents registered at the US Patent and Trademark Office from 1979 to 2002. Results strongly support our hypotheses, revealing that: (1) using both firm core technological heritage and others’ technological heritage has an inverted U-shaped effect on innovation value; (2) employing firm lateral technological heritage is positively related to innovation value; (3) a negative relationship occurs between competitors’ core technological heritage and the value of subsequent innovations.  相似文献

This study is aimed at exploring perceptions of European gatekeepers toward renowned Thai fruit and coffee products protected by geographical indication (GI) and factors influencing purchasing decision of gatekeepers toward imported food products. Sixteen qualitative interviews with distribution channel gatekeepers were administered in Austria, Italy, and Switzerland in 2010. Content analysis and concept mapping were used to analyze data. Results show that Thai GI products might be interesting for European gatekeepers, but the GI attribute alone might not be sufficient to ensure that the product is successful. Support of consistent information and promotion campaigns and fulfillment of other gatekeepers' requirements of both products and suppliers are necessary.  相似文献

We explore sensory experiences and expectations of Italian and German organic consumers when purchasing and eating organic food. Ten focus group interviews were performed and the results were analyzed using qualitative content analysis. Outcomes indicated that although sensory attributes are not the main purchase drivers, flavor and odor are the most important in driving consumers' choice. Findings also suggested that training consumers' sensory abilities offers new market opportunities to organic marketers. From a marketing perspective, Italian consumers seem to equally appreciate nonsubjective as well as subjective marketing information about organic products, whereas in Germany non subjective aspects appear to be predominant.  相似文献

In 1936–39, a group of Oxford tutors inquired, by meansof interviews with entrepreneurs, on price policy and investmentdecisions. A chronology of the inquiry is outlined, based onthe surviving documents found in various archives, focusingon the choice of the subject, on the attempts to provide a theoreticalinterpretation of the phenomena that were discovered, and onthe publication of the results. The role of Harrod is highlighted:it is assessed how far his theoretical approach to the cycleinfluenced the inquiry, and to what extent he modified his viewas a consequence of the group's findings. ‘Our group...best represents the collective mind of economistsin Oxford’ (Harrod to the other members of the OERG, 21April 1939, in ABP 45 and 170).  相似文献

We estimate the effect of household appliance ownership on the labor force participation rate of married women using micro-level data from the 1960 and 1970 U.S. Censuses. In order to identify the causal effect of home appliance ownership on married women's labor force participation rates, our empirical strategy exploits both time-series and cross-sectional variation in these two variables. To control for endogeneity, we instrument a married woman's ownership of an appliance by the average ownership rate for that appliance among single women living in the same U.S. state. Single women's labor force participation rates did not increase between 1960 and 1970. We find evidence in support of the hypothesis that the diffusion of household appliances contributed to the increase in married women's labor force participation rates during the 1960's.  相似文献

This paper critically re-examines the restructuring of public services. Four main decision-making phases are identified: the public oversight to be guaranteed to socially sensitive economic activities; the ways of financing them; the economic organisation of the industry; and the production decisions. By focusing on organisation, the paper reinterprets the market structure in public service industries on the basis of the interactions among three main players: users/citizens, the government and the service supplier. It argues that the issue of public versus private ownership has been overemphasised, and that an effective increase in efficiency can be obtained by introducing appropriate incentives for both public and business players. Instead of using a single policy instrument, namely privatisation, public action ought to be informed by an array of organisational solutions.  相似文献

This paper is a normative analysis of the legal restrictions on international financial movements based on a formal model which analyzes the empirical observation that the degree of financial protectionism is associated with changes in the distribution of welfare among agents. The strategic interactions among four types of agents (a trade union, a firm manager, a financial investor and a government) are analyzed, and the optimal amount of capital control is derived as a Nash perfect equilibrium of a non-cooperative game with imperfect information. I conclude that a financial liberalization proposal can be supported by different coalitions of agents, according to the covariance of domestic and foreign returns and the degree of profitability of domestic industrial projects.  相似文献

The size of the insurance and wealth effects of a change in the Common Agricultural Policy (CAP) for arable crops is estimated. The impact of price uncertainty is accounted for in the specific decision-making structure of the European Union (EU) arable crop producers under nonlinear mean-variance risk preferences. A system of output supply, input demand, and land allocation equations is estimated on a sample of Italian specialized arable crop farms. The simulation of the impact of the recent reforms confirms that farmers' output responses are consistently affected by the size of the insurance and wealth effects.  相似文献
