In applications of expected utility analysis, researchers are confronted with a choice among several utility functional forms. Subjective utility values and probability distributions for price and yield were elicited from Sri Lankan producers of minor export crops. Exponential quadratic and cubic utility functions were estimated. The choice of functional form was found to affect both the classification of risk attitudes and the prediction of harvesting strategy. The exponential function was the best predictor of harvesting strategy because it was the best predictor of mature harvesting. All three functions were equally poor predictors of premature harvesting.  相似文献

The political strength in the EC and UK of the belief that high levels of self-sufficiency make food supplies more secure is demonstrated and explained. The relationship is examined analytically and critically, taking particular account of the priority of food, adjustment costs, and linkages between agriculture and other sectors. The need for a policy of food security in Western Europe is discussed in relation to military, crop and trade uncertainties. Finally, the elements of a more rational policy, including measures of storage, procurement and production independence, are outlined.  相似文献

The historic focus of new products research has been on the ability of new products to enhance the profitability and competitive position of the innovating firm. In this article, Timothy Devinney shows that there exists an overlooked and potentially significant side effect associated with new product innovations: financial risk changes. He reports that significant financial risk changes occurred in approximately 50% of the new product announcements he examined. The magnitude of these financial risk changes translates into overestimates or underestimates of the firm's cost of capital by 17% to 18% and is strongly and positively related to the size of the firm and the firm's new product innovation activity.  相似文献

The purpose of this study was to find out if significant differences exist in patterns of expenditures between elderly and non-elderly consumers, taking poverty status into account. Cluster analysis was used to identify expenditure patterns. Four different expenditure patterns were found. Elderly middle-income and affluent households were more likely to belong to service-using cluster than non-elderly poor households. Nonelderly households were more likely to belong to shelter-dominated cluster than elderly households. Poor households were more likely to belong to homebound cluster, while non-poor households were more likely to belong to car-centred cluster.  相似文献

The Behavioral Perspective Model of purchase and consumption (BPM) portrays the rate at which consumer behaviors take place as a function of the relative openness of the setting in which they occur and the informational and hedonic reinforcement available in or promised by the setting. Each of eight combinations of contingencies based on these explanatory variables is uniquely related to a specific mode of observed consumer behavior. By providing an environmental perspective on consumer behavior, the model makes a critical contribution to the development of contemporary consumer research that frequently decontextualizes its subject matter. It also presents an innovative conceptualization of the nature of marketing strategies.  相似文献

Present economic linkages between the European Union and East Asia are relatively underdeveloped despite the fact that a number of EU member states have deep historical associations within the region. It is imperative that EU business engages itself more intensively in East Asia if Europe is not to become marginalised in an emergent “Pacific century”. *** DIRECT SUPPORT *** A02GP109 00002  相似文献

We argue that the stakeholder perspective on corporate social responsibility is in the process of being enlarged. Due to the process of institutional isomorphism, corporations are increasingly adopting organizational features designed to promote proactivity over mere reactivity in their stakeholder relationships. We identify two sources of pressure promoting the emergence of the proactive corporation -- stakeholder activism and the recognition of the social embeddedness of the economy. The final section describes four organizational design dimensions being installed by the more proactive corporations today -- cooperation, participation, negotiation, and direct anticipation.  相似文献
