The United States (US) exports more than US$6 billion in agricultural commodities to the European Union(EU) each year, but one issue carries the potential to diminish this trade: use of biotechnology in food production. The EU has adopted more stringent policies towards biotechnology than the US. Understanding differences in European and American policies towards genetically modified (GM) foods requires a greater understanding of consumers’ attitudes and preferences. This paper reports results from the first large‐scale, cross‐Atlantic study to analyse consumer demand for genetically modified food in a non‐hypothetical market environment. We strongly reject the frequent if convenient assumption in trade theory that consumer preferences are identical across countries: the median level of compensation demanded by English and French consumers to consume a GM food is found to be more than twice that in any of the US locations. Results have important implications for trade theory, which typically focuses on differences in specialization, comparative advantage and factor endowments across countries, and for on‐going trade disputes at the World Trade Organization. 相似文献

Hofstede's [Hofstede, Geert H. 1980. Culture's consequences: international differences in work-related values. Thousand Oaks, CA: Sage.] cross-country psychological survey of IBM employees finds that some countries (societies) are systematically less tolerant of uncertainty, while uncertainty-tolerance is shown by some theoretic models to be essential to the growth of emerging sectors about which less is known. This paper first uses Durnev, Morck, and Yeung's [Durnev, Art, Morck, Randall, and Yeung, Bernard. 2004. Value-enhancing capital budgeting and firm-specific stock return variation. The Journal of Finance. 59(1): 65–105.] methodology to identify these informationally opaque industries. The hypothesis is then made that countries characterized by high uncertainty aversion (measured by Hofstede's indicator, and two other alternative indicators) will grow disproportionately slower in industrial sectors where information is less available. Using the Rajan and Zingales [Rajan, Raghuram G. and Zingales, Luigi. 1998. Financial Dependence and Growth. American Economic Review. Vol. 88(3): 559–586.] “difference-in-differences” methodology, which is relatively free from the endogeneity problem, the study provides robust evidence of such an industrial growth pattern in 34 countries and 36 manufacturing industries. It also shows that national uncertainty aversion is not driven by underdevelopment of financial sector, inadaptability of civil law systems, lower level of economic or human capital development, labor market inflexibility, or any of many other institutional factors. The results remain robust when religious (Catholic vs. Protestant) composition is used as an instrumental variable for national uncertainty aversion. The international evidence presented helps explain why some countries are slower in embracing “new” (vs. traditional) industries. 相似文献

Who's in charge of the central city? The conflict between efficiency and equity in the design of a metropolitan area 总被引:1,自引:0,他引:1
A circular metropolitan area consists of a central city surrounded by a suburb. Households sort over the two jurisdictions based on public service levels and their costs of commuting to the metropolitan center. Using numerical simulations, we show that (1) there typically exist two equilibria: one in which the poor form the voting majority in the central city and the other in which the rich form the majority in the central city; (2) there is an efficiency vs. equity trade-off as to which equilibrium is preferred; and (3) if the central city contains only poor households, equity favors expanding the central city to include rich households. The third result arises not because of a fiscal subsidy from rich to poor households induced by a property tax but rather because of a change in house price capitalization. 相似文献

Endogenous Group Formation 总被引:1,自引:0,他引:1
While the rules governing the formation of groups engaging in collective action may have significant impact on group size and behavior of members, most experiments on public goods have been conducted with the subjects in exogenously fixed groups or of fixed sizes. We study endogenous formation of groups in a public‐goods provision game by allowing subjects to change groups under three sets of rules: free entry/exit, restricted entry with free exit, and free entry with restricted exit. We find that the rules governing entry and exit do have a significant impact on individual behavior and group‐level outcomes. 相似文献

We analyze a sample of 72 IPO firms that went public between 1992 and 1996 for which we have detailed proprietary information about the amount and cost of D&O liability insurance. If managers of IPO firms are exploiting superior inside information, we hypothesize that the amount of insurance coverage chosen will be related to the post-offering performance of the issuing firm's shares. Consistent with the hypothesis, we find a significant negative relation between the three-year post-IPO stock price performance and the insurance coverage purchased in conjunction with the IPO. One plausible interpretation is that, like insider securities transactions, D&O insurance decisions reveal opportunistic behavior by managers. This provides some motivation to argue that disclosure of the details of D&O insurance decisions, as is required in some other countries, is valuable. 相似文献
