Reform of agricultural policies, notably the continuing elimination of production‐enhancing subsidies, makes it possible for policies to respond to social issues such as the rural environment and health in future. In this paper, we draw on a Rural Economy and Land Use (RELU) research project which is examining the potential for the development of healthy food chains and the implications for human health and the environment. One of the key issues to be addressed is consumers’ willingness to pay for the nutritionally enhanced food products from these new chains, but it is evident that only a partial understanding can be gained from a traditional economics approach. In the paper, we discuss how economists are beginning to incorporate views from other disciplines into their models of consumer choice.  相似文献

A rancorous debate continues to rage over the use of affirmative action policies in college admissions. This article uses a simple signaling model to evaluate the labor market impacts of four types of affirmative action admissions policies. RacE-based preferential policies and policies guaranteeing admission based on high school academic rank may induce discrimination in labor markets when there exists strong heterogeneity in socioeconomic disadvantage within the underrepresented minority group. Under such conditions, it may also be difficult to realize ethnic diversity with disadvantagE-based preferential policies. The article argues instead for affirmative action policies emphasizing intensive college preparation for targeted groups.  相似文献

I re-examine Mankiw-Weil's (MW) claim that house prices will fall 47% by 2007. MW argue that the arrival of the Baby Boom generation at adulthood drove up prices during the 1970s. When the beginnings of the Baby Bust generation matured in the 1980s, prices softened. When this generation arrives in earnest, prices will collapse. I make three points: (1) The regression upon which MW hang their prediction has an implausible -8.1% trend, which drives their prediction. (2) Demand directly influences the rental price; the asset price (MW's variable) is influenced by demand only indirectly. I re-run MW's regression, replacing the asset price with the rental price, and their prediction disappears. (3) Relying on data presented by MW, I show that housing consumption rose during the 1970s, after adjusting for income growth. Just when MW say the asset price of housing was rising, consumers behaved as if the price were falling. Consumers were right: The rental price fell by approximately 20% during the 1970s.  相似文献

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

In this paper we examine the allocation of labor under free agency by developing and testing a model to predict the migration of free agents. Data for individual players are used in a logit model that estimates the probability that a free agent will change teams as a function of several independent variables. Along with other authors, we find that free agents tend to migrate to big cities. In addition, we find evidence that the allocation of labor may be different under free agency than under the reserve clause and suggest a reason why Coase's theorem may not be applicable to this labor market.  相似文献

The purpose of this paper is to examine changes in stock return variances following option introduction. The sample consists of National Market System stocks and employs both transaction returns and returns based on bid and ask quotes. Variances are decomposed into portions attributable to bid-ask spreads, return autocorrelations, and intrinsic variances. Spreads play a negligible role in explaining variance changes. A generally positive component to short-term autocorrelations falls following option introduction, increasing variances over short holding periods. Intrinsic variances fall prior to the October 1987 crash, but do not change after the crash with option introduction.  相似文献

Firms in developing countries cite credit constraints as one of their primary obstacles to investment. Direct foreign investment may ease credit constraints by bringing in scarce capital. Alternatively, if foreign firms borrow heavily from domestic banks, they may crowd local firms out of domestic capital markets. Using firm data from the Ivory Coast, we test whether: (1) domestic firms are more credit constrained than foreign firms, and (2) whether borrowing by foreign firms exacerbates domestic firm credit constraints. Results provide support for both hypotheses. We also find that state-owned enterprises (SOEs) are less financially constrained than other domestic enterprises.  相似文献

We examine the effect of 269 cross‐border listings on rivals in the listing and domestic markets and find that U.S. rivals experience significant gains whereas domestic rivals do not. Both competitive and information effects are important in explaining the reaction of U.S. rivals. Regarding the competitive effects, the reaction of rivals is less favorable when listings originate in developed countries and more favorable when listing firms do not have prior operating presence in the United States. Regarding the information effects, the reaction is less favorable when listings are combined with equity offerings and more favorable when the listing is the first to occur within an industry.  相似文献
