Models that assume only consumer tastes determine the characteristics of supply are restrictive; producers can gain utility from aspects of production and pay for deviating from demand by accepting lower financial returns. We model and measure motivations of California winery owners, and analyze their effects on quality and price. We find utility–maximizers are more likely to produce high quality and set higher quality–adjusted prices. Profit–oriented owners are less likely to produce high quality wines. These results suggest that the presence of hobbyists who enjoy producing high quality may lower financial returns in the segment and discourage profit–maximizers from locating there. 相似文献

This article deals with the prediction problem in linear regression where the measurements are obtained using k different devices or collected from k different independent sources. For the case of k=2, a Graybill-Deal type combined estimtor for the regression parameters is shown to dominate the individual least squares
estimators under the covariance criterion. Two predictors ŷ
c and ŷ
p are proposed. ŷ
c is based on a combined estimator of the regression coefficient vector, and ŷ
p is obtained by combining the individual predictors from different models. Prediction mean square errors of both predictors
are derived. It is shown that the predictor ŷ
p is better than the individual predictors for k≥2 and the predictor ŷ
c is better than the individual predictors for k=2. Numerical comparison between ŷ
c and ŷ
p shows that the former is superior to the latter for the case k=2. 相似文献

This article examines the impact of regulation and market-driven private actions on food safety performance in the meat and poultry industries. We find that private actions account for about 80% and regulation about 20% of the overall reduction in the share of samples of cattle and hog carcasses, ground beef, and broilers testing positive for Salmonella if all regulation and private actions were increased by identical amounts. 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

The Lowry Model Revisited: Incorporating a Multizonal Input-Output Model into an Urban Land Use Allocation Model 总被引:2,自引:0,他引:2
Myung-jin Jun & James E. Moore 《Review of urban and regional development studies : RURDS : journal of the Applied Regional Conference》2002,14(1):2-17
This paper formulates a new generation of Lowry-style models that combine a multizonal input-output model and an urban land use allocation model. Three different types of models are proposed: 1) an unconstrained model, 2) a primal of a linear programming approach that includes land supply constraints, and 3) a modified dual of the linear programming approach that allocates land based on additional conditions of economic efficiency. The modified dual formulation improves upon the limitations of Lowry models and their derivatives. First, the proposed model has sound theoretical underpinnings that incorporate the production theory of input-output models and the behavioral theory of optimization models. Second, the proposed model allocates land on the basis of economic efficiency by imposing a procedure that equalizes shadow prices. And third, the proposed model is an optimization model that fully accounts for the spatial and sectoral relationships of multiplier effects determining land use demand. 相似文献

All prestigious or highly-paid occupations in Britain are dominated by men: this is as true of the public sector as it is of industry. This article examines the evidence for discrimination in the public sector. It deals with both the situation at work and the one at home. It looks at various explanations as to why this is the case, as well as the evidence on how men and women deal with the inequality. The author concludes that there are good reasons why men and women do not see or confront the issues discussed in her article. Unless men and women wake up to the fact that we live in an unequal society and wish to see the glass ceiling well and truly broken, little is likely to change. 相似文献

Many employers are extending workplace rights by allowing for more employee voice in decision making. Numerous unionized organizations have established formal worker participation processes to help achieve this end and to improve organizational performance. Based largely on theory, such processes are normally designed to operate independently from the bargaining process. The purpose of this study was to examine the relationship between participation and bargaining processes, and the effect of this relationship on workplace satisfaction. A total of 712 Midwest union officials were surveyed, and the results indicate that the processes tend to become integrated in the workplace. Further, union officials' workplace satisfaction was greater where formal worker participation is institutionalized within the bargaining process. 相似文献

We hypothesize that the firm’s regulatory environment influences the sensitivity of its equity value to information. Using
intraday stock price data of utilities operating in differing regulatory environments we test for systematic differences between
the responsiveness of stock prices of utility firms operating in deregulated and regulated environments to a common information
set. Our findings reveal sharp differences in responses, with those of utilities operating in deregulated environments the
strongest, and the responses of utilities in highly regulated environments the weakest. While the evidence supports our hypothesis,
in a broader sense, the evidence suggests that deregulation aids in the process of price discovery. We also find evidence
that suggests that deregulation, per se, does not lead to higher stock price volatility.
