In Denmark the poultry industry and the National Committee for Pig Production, together with the feedstuff industry, decided to voluntarily abolish the use of all Anti-microbial Growth Promoters (AGP). The poultry industry abolished the use of AGP from 15 February 1998 and the pig industry followed on 1 March 1998 (for pigs over 35 kg) and 1 January 2000 (for pigs under 35 kg). To evaluate the effects of the removal of AGP, data from both the poultry and pig industries were collected prior to and after the removal of AGP from animal feed. Utilizing these production data, this paper calculates economy-wide effects of the removal of AGP using the Agricultural Applied General Equilibrium (AAGE) model of the Danish economy. The results show that the long-term effects are a moderate decline in the production and export of pig meat, and a positive indirect effect on other industries including poultry due to lower rental rates for primary factor inputs. The overall implication is a small decline in real GDP of 0.03%, reducing public and private consumption by 68 DKK per capita per year in Denmark.  相似文献

Living next to godliness: Residential property values and churches   总被引:1,自引:0,他引:1  
This article extends the analysis concerning the impact of neighborhood churches on residential property values by investigating nearly 5,000 residential property transactions in Henderson, Nevada, between January 1986 and December 1990. We find that real property values decrease, at a decreasing rate, as distance from a neighborhood church increases. This result is the opposite of that reported by Do, Wilbur, and Short in a previous edition of this journal. We bolster our findings by showing that distance from the site of a future church has little or no impact on residential property values, whereas distance from an existing church is associated with lower property values. Our evidence indicates that neighborhood churches are amenities that enhance the value of neighborhood residential property. Finally, we demonstrate that larger churches (as measured by square foot of lot size) tend to have a greaterpositive impact on residential property values.  相似文献

Ziel des Beitrags ist die Beantwortung der Frage, welche Faktoren die Nutzung von Fernsehserien erkl?ren k?nnen. Kann sie im Wesentlichen auf Habitualisierung und strukturelle Rahmenbedingungen zurückgeführt werden, oder l?sst sie sich dadurch erkl?ren, dass die Erwartungen an die Qualit?t von Fernsehserien und die Wahrnehmung von Qualit?tseigenschaften der verschiedenen Serien zwischen den Rezipienten variieren? Zun?chst werden die theoretisch relevanten Faktoren für ein Modell der subjektiven Qualit?tsauswahl identifiziert und operationalisiert. Anschlie?end wird in einer empirischen Studie geprüft, ob diese Faktoren einen Einfluss auf die Nutzung der Fernsehserien haben. Die Untersuchungsergebnisse zeigen, dass die drei Elemente des theoretischen Ansatzes — Qualit?tserwartungen, Qualit?tswahrnehmungen und Qualit?tsurteile — die Seriennutzung zu einem betr?chtlichen Teil erkl?ren k?nnen. Der Vorteil dieses Ansatzes gegenüber dem Uses and Gratifications Approach besteht darin, dass die Eigenschaften des Angebots im Mittelpunkt stehen. Damit wird es m?glich, Aussagen darüber zu machen, welche wahrgenommenen Merkmale des Angebots für die Nutzungsentscheidungen der Rezipienten relevant sind.  相似文献

Cost information sharing with uncertainty averse firms   总被引:1,自引:0,他引:1  
Summary. A homogeneous Cournot duopoly with asymmetric information is analyzed. Every firm learns its own marginal cost parameter, but not the marginal cost parameter of the opponent. Every firm can commit to revealing its private information to the other firm, i.e. to share information. The influence of uncertainty aversion on the readiness of the duopolists to share cost information is analyzed. Uncertainty aversion is modeled according to the Choquet utility theory. It is shown that low uncertainty aversion leads the firms to share information, while high uncertainty aversion leads the firms not to share. A simple economic explanation for this result is given.Received: 5 January 2001, Revised: 7 May 2003, JEL Classification Numbers: D43, D81, D82.I wish to thank Jürgen Eichberger, Volker Krätschmer, Willy Spanjers, seminar participants at Universität des Saarlandes, seminar participants at University College London, participants in the conference of the Verein für Socialpolitik in Mainz 1999 and an anonymous referee for helpful comments.

This paper analyses the quantitative effects of using economic instruments in health policy on the basis of price elasticities calculated from estimated demand systems. The nutritional effects of various taxation schemes are compared for households in different age groups and social classes. Focusing on the consumption of saturated fats, fibre and sugar; it is generally found that the impact of price instruments is stronger for lower social classes than in other groups of the population. With regard to age groups, it is mostly the youngest that decrease their demand for saturated fat in response to price changes, while it is mostly the middle-aged who exhibit price responsiveness in their demand for sugar. These groups are however not considered as key target groups for dietary regulation; thus tax instruments may be effective in improving diets on average, but the design of the instruments and the targeting of vulnerable groups with special needs should be done with care. It should be noted that a tax on a single nutrient or food may have undesired effects on the demand for other food components, though this may be avoided by introducing taxes/subsidies on several food products simultaneously.  相似文献
