We compare consumer valuations of beef ribeye steaks from cattle produced without growth hormones or genetically modified corn in France, Germany, the United Kingdom, and the United States. Results suggest that French consumers place a higher value on beef from cattle that have not been administered added growth hormones than U.S. consumers; however, valuations of non-hormone-treated beef are statistically indistinguishable across Germany, the United Kingdom, and the United States. Results also suggest that European consumers place a much higher value on beef from cattle that have not been fed genetically modified corn than U.S. consumers. 相似文献

Traffic light (TL) labels that inform consumers regarding product safety have received increasing attention in different fields. Behind the background of behavioural economics, this paper presents the results of a split‐sample choice experiment conducted in Germany to evaluate the impact of TL labelling on purchases of food and financial products. We hypothesize that consumers experience different levels of involvement with these two types of products, leading to different recommendations regarding the use of TLs. The results show that TLs affect consumer purchases of both product groups by focusing their attention on specific product attributes. For food, whereas the low‐fat attribute has no significant impact on food choices that do not include TLs, this attribute has a positive impact on choices once it is signalled with a TL label. The positive evaluation of the organic production attribute of a food product without a TL decreases when the same product is labelled with a TL. In the case of financial products, TLs significantly reinforce the impact of all characteristics on choice probability. TLs also generate a halo effect with regard to return variance. Although consumers demonstrate different levels of involvement for the two types of products, involvement does not always impact the evaluation of attributes. Compared with less involved consumers, more involved consumers exhibit more heterogeneous evaluations of the return variability attribute in the case of the financial product and the organic attribute in the case of the food product. 相似文献

This paper presents an analysis of the changing food risk perceptions of German consumers over the period 1992 to 2002. We analyse the respondents' general risk attitudes and their specific perceptions of food risks. Using cluster analysis we generate a typology of four consumer types. One group is worried about natural food risks, the second does not worry about any types of food risks, the third is concerned about technical food risks and the fourth is concerned about all food risks. A multinomial logit analysis identifies factors that describe the classification of households in this grouping. General risk attitudes and knowledge about food risk are significant variables in the explanation. 相似文献

Foreign direct investment is generally expected to play a significant role as a multiplier of modern production and management
know-how in Central Eastern European transition economies. The following paper examines the various mechanisms by which such
technological spillover effects could in theory take place and compares them with the results of an empirical study of their
practical significance for Hungarian industry. 相似文献

Zusammenfassung Pflege bei Osteoporose — Die Osteoporose ist eine ernsthafte Volkskrankheit. Sie geht einher mit einem erh?hten Knochenbruchrisiko,
bedingt durch die Verminderung von Knochenmasse und die Ver?nderung der Mikroarchitektur. Der Knochen wird instabil gegenüber
den Belastungen des Alltags – Knochenbrüche bei Bagatellunf?llen, Fehlstatik und Schmerzen sind die Folge. 相似文献

Leadership and the Provision of Safe Food 总被引:5,自引:0,他引:5

Modern food production typically involves many interacting stages and two or more decision makers. There is reason to believe that inputs in determining quality likely complement. And it is not possible to regulate many of these inputs. In a food production system possessing these characteristics, we show that leadership by one or more firms through communicating actions may be used as a mechanism to increase overall food quality. As there may be no private incentive to lead, there may be strategic merit in assigning liability through legislation. We also suggest the possibility that genetics are leadership instruments in hog production systems. 相似文献
