The motivation for the present study is to understand food choice in relation to animal food production and to study how preferences are influenced by information. To do this, we carried out a choice experiment. In the analysis, we focus on chickens reared indoors and outdoors and chicken labelled campylobacter-free versus non-labelled chicken. The results suggest that there is a positive willingness to pay (WTP) both for chicken reared outdoors and for campylobacter-free labelled chicken. Information about rearing methods resulted in a higher WTP for chicken reared outdoors, while information about campylobacter had both positive and negative effects on respondents’ WTP. The highest increase in WTP for campylobacter-free labelled chicken was found for one of the high risk groups, individuals with poor kitchen hygiene.  相似文献

With the proliferation of regional trade agreements since the late 1980s and early 1990s, preferential rules of origin have also proliferated. The discussion on these rules has gradually shifted from a purely technical discussion (“how to establish the origin of goods not wholly obtained in one country”, and hence, “how to apply trade preferences in these cases”) to a wider discussion also touching upon the transaction costs caused by having a “spaghetti bowl” of rules, and the actual or presumed neo-protectionist use that is being made of them. In the context of the discussion on possible policy options for developing countries simultaneously involved in (or negotiating) regional and multilateral trade agreements, this article will first give a brief overview of the findings of the recent empirical literature. Some indications are then presented as to what such policy options could look like. This paper was first presented at the Ad-hoc Expert Group Meeting on The Development Interface between the Multilateral Trading System and Regional Trade Agreements, Session III Regulatory Provisions in RTAs, Palais des Nations, Geneva, 15-16 March 2007. It is partly based on P. De Lombaerde, L. J. Garay : Preferential Rules of Origin: EU and NAFTA Regulatory Models and the WTO, in: The Journal of World Investment & Trade, Vol. 6, No. 6, 2005, pp. 953-994; and L. J. Garay, P. De Lombaerde: Preferential Rules of Origin: Models and Levels of Rulemaking, in: S. Woolcock (ed.): Trade and Investment Rulemaking: The Role of Regional and Bilateral Agreements, Tokyo 2006, UNU Press, pp. 78-106.  相似文献

This article reviews the academic contributions of Olav Sorenson, recipient of the 2018 Global Award for Entrepreneurship Research. His work has advanced scholarly understanding of how entrepreneurship and innovation are strongly embedded in socially and spatially bounded relationships. Based on meticulous empirical studies using a broad range of methods, he has challenged conventional models of new firms’ location choices, explained patterns of and determinants of knowledge diffusion, and considered how social networks can lead to economic advantages. This article discusses Sorenson’s work specifically focusing on three themes—(i) the geography of entrepreneurial activity, (ii) social capital, and (iii) the evolution of learning and innovation—highlighting scholarly contributions and insights for management practice and public policy.  相似文献

The main aim of the present study was to examine whether an ethical organizational culture is associated with sickness absence in a Finnish public sector organization at both the individual (within-level) and work unit (between-level) levels. The underlying assumption was that employees working for organizations that are characterized by a strong ethical organizational culture report less sickness absence. The sample consisted of 2192 employees from one public sector city organization that included 246 different work units. Ethical organizational culture was measured with the Corporate Ethical Virtues scale covering eight sub-dimensions. Sickness absence was inquired by asking the participants to report how many days they had been absent from work because of their own sickness over the past year. Multilevel structural equation modelling showed that, at the individual level, perceptions of a strong ethical organizational culture were associated with less sickness absences after controlling for the background factors. This link was not found at the work-unit level. The findings indicate that an ethical organizational culture plays a significant role in enhancing employee well-being measured as sickness absence. It seems that especially supervisor’s ethical role modeling and possibilities to discuss about ethical issues are important factors in preventing sickness absence in the organizations.  相似文献

Research about codes of corporate ethics has hitherto taken a hypothetical, correct meaning of codes for granted. The article problematises the dichotomous categories intrinsic and subjective meanings of codes. I address the question if professionals in finance accept codes of business. The particular mentality of stockbrokers and traders constructs the way they judge restrictions such as company codes of ethics. While neglecting dimensions of ethics beyond known rules, brokers and traders distrust good ethics as a possible end in itself. Many professionals in the financial market perceive efforts to integrate ethical reasoning in work as only means for maximising business opportunities.  相似文献

In the context of the ongoing financial and economic crisis reference is frequently made to the Great Depression of the 1930s and fears are voiced that we may have embarked on a similar path. This article looks at the conditions prevailing back then and compares them with the present economic environment. From this some conclusions are drawn as to the likelihood of a recurrence of the disaster.  相似文献

Since the outbreak of the financial and economic crisis, confidence in politicians as well as the economists in their advisory expert panels seems to be at an all-time low. Why do politicians reject science-based advice unless it fits into their political agenda? Are economists misunderstood by politicians and vice versa? The tension between the ideal of evidence-based policy-making and the reality of policy-based evidence-making is hardly a new phenomenon. Therefore, the expectation that Donald Trump, the Brexiteers and European populists will necessarily disappoint their voters because they simply cannot deliver what they have promised is misleading. Experts would be well advised to use the debate on the post-factual era as an impetus to reflect critically on their profession. One opinion expressed in this Zeitgespräch is that the contested societal and political impact of modern economics is due to its restricted scientific self-concept. A more open, pluralistic and transdisciplinary self-definition of economics would strengthen its societal influence. Another contributor ponders the proper incentives to persuade academic economists to provide economic policy advice. Key is the independence of advisory institutions like the German Council of Economic Experts. The selection of people with the best scientific qualifications will ensure the reputation of such institutions.  相似文献
