Consumers worldwide are increasingly concerned with sustainable production and consumption. Recently, a comprehensive study ranked 17 countries in regard to their environmentally friendly behaviour among consumers. Brazil was one of the top countries in the list. Yet, several studies highlight significant differences between consumers' intentions to consume ethically, and their actual purchase behaviour: the so‐called ‘Attitude‐Behaviour Gap’. In developing countries, few studies have been conducted on this issue. The objective of this study is therefore to investigate the gap between citizens' sustainability‐related attitudes and food purchasing behaviour using empirical data from Brazil. To this end, Brazilian citizens' attitudes towards pig production systems were mapped through conjoint analysis and their coexistence with relevant pork product‐related purchasing behaviour of consumers was investigated through cluster analysis. The conjoint experiment was carried out with empirical data collected from 475 respondents surveyed in the South and Center‐West regions of Brazil. The results of the conjoint analysis were used for a subsequent cluster analysis in order to identify clusters of Brazilian citizens with diversified attitudes towards pig production systems, using socio‐demographics, attitudes towards sustainability‐related themes that are expected to influence the way they evaluate pig production systems, and consumption frequency of various pork products as clusters' background information. Three clusters were identified as ‘indifferent’, ‘environmental conscious’ and ‘sustainability‐oriented’ citizens. Although attitudes towards environment and nature had indeed an influence on citizens' specific attitudes towards pig farming at the cluster level, the relationship between ‘citizenship’ and consumption behaviour was found to be weak. This finding is similar to previous research conducted with European consumers: what people (in their role of citizens) think about pig production systems does not appear to significantly influence their pork consumption choices. Improvements in the integrated management of this chain would better meet consumers' sustainability‐related expectations towards pig production systems. 相似文献

This article explores project management offices (PMOs) through community of practice theory. Preliminary results from a national health care case study are used to confirm the legitimacy of this approach. Today's knowledge‐based economy calls for mechanisms to share knowledge. The issue of making more with less is at stake in order to reuse good practices, support innovative practice, and prevent the reinvention of the wheel. Members of these communities are at the heart of the learning process. The originality of this research is that it sheds light on PMOs in a new theoretical perspective within the field of knowledge management. 相似文献

We examine determinants of different types of International New Ventures (INVs), namely Export Start‐up, Geographically Focused Start‐up, Multinational Trader, and Global Start‐up. Whereas this typology of INVs has been widely accepted in the literature, empirical testing of the determinants of INV types is largely missing. Our arguments build on the International New Venture Theory (INVT). Hypotheses generated from our framework are tested on 195 German high‐tech enterprises. Results show that growth orientation, prior international experience, knowledge intensity, product differentiation, and learning orientation distinguish significantly between the different INV types. 相似文献

Nach der Atomkatastrophe in Fukushima hat die Bundesregierung beschlossen, bis Mitte Juni die Zukunft der Atomenergie in Deutschland
zu überdenken. Dabei k?nnen unterschiedlich weitgehende Szenarien betrachtet werden. Sie reichen von einer Rücknahme der im
letzten Herbst beschlossenen Laufzeitverl?ngerung bis hin zum vollkommenen Ausstieg aus der Kernkraft. Die Autoren vertreten
grunds?tzlich die Auffassung, dass die wirtschaftlichen Folgen eines Atomausstiegs zu bew?ltigen sind. Mit einer Steigerung
der Energiepreise muss allerdings gerechnet werden — wie deutlich diese ausf?llt, und welche Referenzwerte herangezogen werden
müssen, h?ngt von vielen Faktoren ab. 相似文献

In light of the shortcomings of the Stability and Growth Pact, there has been a recognition that a surveillance framework
is needed which goes beyond fiscal issues to cover wider macroeconomic factors. The question arises whether the surveillance
and connected reform criteria should be applied symmetrically, to all members of the eurozone, or whether they should specifically
target countries with current account deficits. 相似文献

This paper examines the effects of the Economic and Monetary Union on demand for foreign reserves. The traditional theory
on demand for international reserves assigns a pivotal role to imports. However, in a currency union part of imports are settled
in the common currency, leaving no incentive for keeping foreign reserves. Moreover, the pooling of the demand for reserves
in the currency union and an increasing role of a currency as an international reserve currency may also influence, among
other things, the union demand for reserves. Based on estimated demand functions for reserves it is shown that the Economic
and Monetary Union has reduced the demand for reserves substantially. It is argued that an enlargement with new member countries
of the European Union will result in further savings of reserves. A simple calculation at the end of the paper illustrates
the welfare gain associated with the reduced need of reserves in the Economic and Monetary Union. 相似文献

Organic agriculture, which produces commodities that can be qualitatively differentiated from conventional food products, has grown into an important market in many countries. The dynamics of commodity prices in both sectors are partly interdependent, but are also shaped by independent determinants and have rarely been studied. We analyze organic food markets and their interdependencies with conventional markets in the context of wheat markets in Germany, which have been subject to a number of fundamental changes during the last two decades. Based on institutional market characteristics, we suggest a flexible Markov‐switching asymmetric time series model. We find a pronounced temporal sequence of market phases that differ in their asymmetric dynamics and the extent to which the organic price is influenced by the conventional price. Organic wheat prices tend to be increasingly connected to prices of conventional wheat. 相似文献
