New plant biotechnologies called new breeding techniques (NBT), which will follow the present genetically modified (GM) technology, have appeared and are attracting attention worldwide. The first purpose of this study was to show consumer attitudes toward traditional plant breeding, GM, and NBT crops. The second purpose was to verify the validity of a psychological model determining the acceptance of NBT crops. A survey was conducted in Japan with 657 randomly selected adult participants. The results showed that perceived risk, perceived benefit, trust, sense of bioethics, anxiety, and anger play an important role in the personal and public acceptance of NBT and indicated that trust and anxiety are especially important factors in both situations. 相似文献

The aim of evidence-based guidelines is primarily to improve patient outcomes without adding to the existing cost of care because both payers and policymakers want to identify health care costs that do not result in benefit to the patient. The purpose of the reported project was to generate a practice guideline for the treatment of uncomplicated acute cystitis in a female population, to determine the extent to which the guideline would be used by providers and to measure the cost and quality of outcomes from its use. A retrospective chart review was used to gather pre-guideline practice and cost data. Measurements included the type, frequency, and duration of antibiotic therapy and the use of urine cultures and both complications and routine followup visits. The implementation of an outpatient practice guideline resulted in a significant change in antibiotic prescribing and a trend toward a change in ordering cultures and clinic followup. There was also a significant decrease in treatment costs. 相似文献

We document the determinants of the expectation heterogeneity of stock price forecasters on TOPIX. Monthly panel data collected by QUICK Corporation in the Nikkei Group via surveys is utilized in the process. We examine the determinants of expectation heterogeneity by categorizing our sample into buy-side and sell-side professionals and demonstrate that the co-existence of different types of professionals contributes to the expectation heterogeneity. We show that buy-side and the sell-side professionals, who possess different business goals, differentiate the information contents as well as their interpretations of the same information in their forecasts, contributing to the expectation heterogeneity. In addition, we investigate the interactive expectation formulation of buy-side and sell-side professionals and find that buy-side professionals incorporate the sell side's ideas regarding future stock prices into their own forecasts, but refer exclusively to their own ideas when relating foreign exchange rates to future stock prices. Meanwhile, sell-side professionals tend to utilize buy-side professionals' ideas about future prices in order to improve their research and ingratiate themselves to their clients, that is, to the buy-side professionals. We demonstrate that this interactive expectation formulation also contributes to the generation of the expectation heterogeneity. 相似文献

It has been argued in the economic literature that job search through informal job networks improves the employer–employee match quality. This paper argues that inventors' research collaboration networks reduce the uncertainty of firms about the match qualities of inventors prior to hiring. We estimate the effect of inventors' collaboration networks on their productivity and mobility using the U.S. patent application database. It is found that networked inventors are more productive and have longer tenure than non-networked inventors. The evidence from fixed-effect regressions shows that the higher productivity and longer tenure of networked inventors are not solely attributable to unobserved ability of inventors or unobserved characteristics of firms. These results are consistent with the job match hypothesis between inventors and firms through their collaboration networks. 相似文献

By taking into account factor market interactions, the theory of strategic trade policies can consistently explain the fact that less efficient countries offer greater export subsidies to the most technologically advanced industries because in these countries there may be greater differences in efficiency of production technology between industries than in more efficient countries. 相似文献

Agriculture is the focus of much contention in free trade negotiations. The Japanese government is against liberalizing the rice trade on the grounds that it would threaten “national food security” in the events of such shocks as crop failure and embargoes. Trade liberalization is expected to make the Japanese economy more dependent upon food imports and, thus, more susceptible to these risks. Using a computable general equilibrium model with a Monte Carlo simulation, we quantify the welfare impacts of productivity shocks and export quotas by major rice exporters to Japan and found little evidence of Japan suffering from such shocks. 相似文献

This paper investigates the movement of gross outputs and resource allocation under the condition allowing for substitutability among various inputs within the framework of a simple general equilibrium model with both non-traded intermediate inputs and interindustry flows. Particular attention is paid to the sufficient conditions under which the gross output of the protected industry goes up and the industry attracts domestic factors under the Bhagwati-Srinivasan restriction on tariff change. 相似文献
