In the continuing debate over the impact of genetically modified (GM) crops on farmers of developing countries, it is important to accurately measure magnitudes such as farm‐level yield gains from GM crop adoption. Yet most farm‐level studies in the literature do not control for farmer self‐selection, a potentially important source of bias in such estimates. We use farm‐level panel data from Indian cotton farmers to investigate the yield effect of GM insect‐resistant cotton. We explicitly take into account the fact that the choice of crop variety is an endogenous variable which might lead to bias from self‐selection. A production function is estimated using a fixed‐effects model to control for selection bias. Our results show that efficient farmers adopt Bacillus thuringiensis (Bt) cotton at a higher rate than their less efficient peers. This suggests that cross‐sectional estimates of the yield effect of Bt cotton, which do not control for self‐selection effects, are likely to be biased upwards. However, after controlling for selection bias, we still find that there is a significant positive yield effect from adoption of Bt cotton that more than offsets the additional cost of Bt seed. 相似文献

In this paper we discuss the role of commercial non-profit firmsin the provision of public services, referring to three casestudies to illustrate the main issues. We consider problemsof corporate governance, including the role of the board ofmembers and the scope for performance-related pay. We discussthe performance of such non-profit firms in terms of qualityand costs, the particular finance problems of these firms andthe implications for risk taking. We also suggest various aspectsof non-profit behaviour in public service provision that presentinteresting avenues for future research. 相似文献

Declining populations in rural and regional areas have become a high political priority in Australia. Calls for measures to support rural communities have been prompted by substantial population declines in some country areas. In Europe and the USA, similar political pressures to halt population losses in rural and regional areas are also apparent; often as a component of the multifunctionality of agriculture. The question addressed in the present paper is whether or not the Australian tax‐paying public would be willing to pay to avoid losses of people from rural and regional areas that may result from environmental protection measures. As an integral component of two recent non‐market, environmental valuation exercises using Choice Modelling, the value of the benefits associated with the maintenance of rural populations has been estimated. The results demonstrate that a positive existence value is held primarily by urban dwellers for rural population levels. 相似文献

The vast number of high quality corporate image and advocacy films, combined with the many other instruments of persuasion and control by corporations, powerfully direct the attitudes of the populace. In the absence of equal access, the best protection against deception from any powerful institution is skepticism — minds trained in critical thinking. But technically proficient, expensive films (costing from $50,00 to $600,000) encourage credulity instead of thought. The schools should train young people, therefore, how to resist corporate film propaganda by teaching them the kinds of questions to ask. An analysis of Chesebrough-Pond Corporation's Family offers an effective method through combining traditional rhetorical awareness of the speaker in a communication, knowledge of informal fallacies, the National Council of Teachers of English Committee on Public Doublespeak's ‘intensify/downplay’ approach, and Richard Ohmann's method in ‘Doublespeak and Ideology in Ads’. 相似文献

The purpose of this article is to discuss the implications of interstate banking for consumers. The article describes the current structure of the banking industry, the history of legislation affecting interstate banking, and the expected effects of interstate banking on bank operating costs, availability of local funds, and concentration and competition within local banking markets as well as the anticipated effects on consumers of banking services. © 1995 John Wiley & Sons, Inc. 相似文献

Many of America's most successful companies have gone through a life cycle similar to the product life cycle. They began as innovators, and then grew to be giants in their markets. But, as their products mature, they need new products to continue company growth. However, the organizational structure of an established company is no longer suited for innovation. The authors provide some insight into this cycle, and offer some solutions for big companies which need new products. 相似文献
