The development and implementation of effective systems to identify vulnerabilities in food chains to chemical and microbiological contaminants must take account of consumer priorities and preferences. The present investigation attempted to understand consumer perceptions associated with chemical and microbiological contaminants in four specific food chains (drinking water, farmed salmon, chicken and milk powder). To this end, ten focus group discussions were held in five different countries (Poland, Ireland, the Netherlands, France and Brazil). Consumers expressed higher concerns about chemical, as compared with microbial, contaminants. Chemical contaminants were more strongly associated with the potential for severe consequences, long-term effects and lack of personal control. Traceability was considered by consumers as a useful tool that offers the potential to improve consumer confidence in food safety.  相似文献

DIFFUSION MODELS FOR EXCHANGE RATES IN A TARGET ZONE   总被引:2,自引:0,他引:2  
We present two analytically tractable diffusion models for an exchange rate in a target zone. One model generalizes a model proposed by De Jong, Drost, and Werker (2001) to allow asymmetry between the currencies which is often an important feature of data. Estimation of the model parameters by the method of Kessler and Sørensen (1999) using eigenfunctions of the generator is investigated and shown to give well-behaved estimators that are easy to calculate. The method is well suited to the models because the eigenfunctions are known so that explicit estimating functions are obtained, and because the state space is a finite interval, for which it is known that the method can be made arbitrarily efficient by including sufficiently many eigenfunctions. The model fits data on exchange rates in the European Monetary System well. In particular, the asymmetry parameter is significantly different from zero for three out of four currencies. An alternative diffusion model is presented with similarly nice properties, but with different dynamics that allow constant volatility near the boundaries of the target zone. No-arbitrage pricing of derivative assets is considered, and the effect of realignments is briefly discussed.  相似文献

This study seeks to answer the following question: Can sales representatives enhance their performance through their acceptance of information technology (IT) tools? Using data collected from two companies, we show that despite uncertain results and the frequent resistance among salespeople to IT interventions, IT acceptance indeed has a positive effect on sales performance. This occurs because salespeople using IT expand their knowledge and, in turn, gain improved targeting abilities, enhanced presentation skills, and increased call productivity. Thus, sales representatives have a strong incentive to accept IT because doing so is likely to sharpen their own job performance.  相似文献

Although there is a high level of practitioner, policymaker, and scholar interest in social entrepreneurship, most research is based on case studies and success stories of successful social entrepreneurs in a single country. We develop a methodology to measure population-based social entrepreneurship activity (SEA) prevalence rates and test it in 49 countries. Our results provide insights into institutional and individual drivers of SEA. Using the Global Entrepreneurship Monitor (GEM) methodology of Total Entrepreneurial Activity (TEA), we find that countries with higher rates of traditional entrepreneurial activity also tend to have higher rates of social entrepreneurial activity. We develop a broad definition of social entrepreneurship and then explore types based on social mission, revenue model, and innovativeness.  相似文献

Indirect taxes on transportation activities that pollute can correct externalities and close the gaps between private and social costs. However, policy makers often find such Pigou taxes difficult to implement because of political resistance due to possibly adverse affects on equity. For this reason it is important to assess the distributional aspects of environmental levies. This article estimates properties of the demand for transportation in parametric and non-parametric analyses of Consumer Expenditure Surveys for the United States and finds patterns in the resulting set of Engel curves. Private transportation using air flights and new cars has Engel elasticity above unity while public transportation via mass transit has Engel elasticity below unity. The findings can be interpreted in an important way since they show that a differentiated scheme of environmental taxes on transportation may function progressively. A Pigou scheme with larger taxes on modes of transportation that pollute more appears to coincide with larger levies on luxury modes preferred by richer households.  相似文献

The Global Entrepreneurship Monitor research program was designed as a comprehensive assessment of the role of entrepreneurship in national economic growth. The conceptual model reflected in a wide range of factors associated with national variations in entrepreneurial activity and the major contextual features. Empirical tests of the many relationships in the model required four major data collection activities: adult population surveys, unstructured interviews with national experts, self-administered questionnaires completed by national experts, and assembly of relevant standardized measures from existing cross-national data sets. Adult population surveys were implemented to identify those entrepreneurially active, which required a set of precise criteria and careful processing to ensure harmonized counts and prevalence rates across 41 countries. Existing evidence on measures of reliability indicates that the measures met contemporary standards and the project was cost-effective.  相似文献

Recent changes in many areas of Government policy as well as changes in the private sector have had major impacts on the provision of services in rural areas of New Zealand. This report describes the results of a New Zealand survey of 795 rural consumers. The results emphasise how the problems perceived as most important to people in rural areas are essentially linked to fundamental services such as housing, water, communications, and transport. Though this element of basic needs is covered in the consumer policy literature it is not a feature that tends to be emphasised. The survey also gauges some aspects of rural consumers' knowledge of their entitlements under New Zealand consumer law and their familiarity with, and use of, consumer advisory and support services.  相似文献
