The paper jointly evaluates the determinants of switching to Jasmine rice and its productivity while allowing for production inefficiency at the level of individual producers. Model diagnostics reveal that serious selection bias exists, justifying use of a sample selection framework in stochastic frontier models. Results from the probit variety selection equation reveal that gross return (mainly powered by significantly higher Jasmine rice price), access to irrigation and education are the important determinants of choosing Jasmine rice. Results from the stochastic production frontier reveal that land, irrigation and fertilisers are the significant determinants of Jasmine rice productivity. Significantly lower productivity in Phitsanulok and Tung Gula Rong Hai provinces demonstrate the influence of biophysical and environmental factors on productivity performance. The mean level of technical efficiency is estimated at 0.63 suggesting that 59% [(100 ? 63)/63] of the productivity is lost due to technical inefficiency. Policy implications include measures to keep Jasmine rice price high, increase access to irrigation and fertiliser availability, as well as investment in education targeted to farm households which will synergistically increase adoption of Jasmine rice as well as farm productivity.  相似文献

This paper analyses managers' moral decision-making, and studies the role of ethical theories in it by following the research tradition using the multidimensional ethics scale. The research question is: what kinds of ethical dimensions do Finnish business managers reveal when they are making moral decisions, and how have these dimensions changed in the 1990s? This question is answered by examining what kinds of factors emerge when the multidimensional ethics scale is used to analyse Finnish managers' attitudes toward moral dilemmas. The results show that Finnish managers' decision-making reflects a variety of ethical theories. Teleological thinking is strongly emphasised by Finnish managers, and relativist thinking is used as well, but often combined with either deontology or justice thinking. In addition, a strong moralistic dimension emerged in Finnish managers' decision-making. The analysis was carried out in two different surveys in years 1994 and 1999, and the results show that the ways of decision-making were more complex at the end of the 1990s than almost six years earlier.  相似文献

The relationship between Karl Pearson and the Scandinavian statisticians was more of a competitive than a collaborative nature. We describe the leading statisticians and stochasticists of the Scandinavian school, and relate some of their work to the work of Pearson.  相似文献

This study examines the effect of sample size on the mean productive efficiency of firms when the efficiency is evaluated using the non-parametric approach of Data Envelopment Analysis. By employing Monte Carlo simulation, we show how the mean efficiency is related to the sample size. The paper discusses the implications for international comparisons. As an application, we investigate the efficiency of the electricity distribution industries in Australia, Sweden and New Zealand.  相似文献

基于终极产权论的股权结构与公司绩效研究   总被引:1,自引:0,他引:1  
文章依据终极产权理论,对我国制造业上市公司股权进行重新划分,分为国有终极控制权和非国有终极控制权.采用面板数据方法,在控制样本选择偏差和股权内生变量的前提下研究股权结构对公司绩效的影响.实证结果表明,终极控制权比例与国有控股公司绩效CFOA、M/B呈显著的倒U性关系,而与传统绩效指标ROE、ROA无显著关系,在非国有终极控股公司中则不存在上述关系.流通A股比例与公司绩效关系不确定.样本选择偏差、机构投资者和外资股对公司绩效也有不同的影响.  相似文献

Nearly all studies of consumers’ willingness to engage in ethical or socially responsible purchasing behavior is based on unconstrained survey response methods. In the present article we ask the question of how well does asking consumers the extent to which they care about a specific social or ethical issue relate to how they would behave in a more constrained environment where there is no socially acceptable response. The results of a comparison between traditional survey questions of “intention to purchase” and estimates of individuals willingness-to-pay for social attributes in products reveal that simple survey questions are too “noisy” to provide operationally meaningful information and overstate intentions to a considerable extent.

There is substantial research and policy interest in the relationship between firms and the natural environment, including how this relationship is influenced by regulators, international pressures, rival firms and stakeholder demands. With some exceptions, the ‘softer’ dimensions of environmental aspect management – how attitudes, beliefs and perceptions and the human factors drive corporate behaviour – have been understudied. The work that exists tends to be informal, and allows little scope for the statistical validation that is required for robust inference. This paper examines whether corporate values towards the environment affect a firm's environmental performance. It uses survey methods as well as content and discourse analyses of interview text and corporate reports and web sites to explore the links between managerial ‘mindsets’ and the environmental performance of the firms of which they are a part. Though the application is Argentina, the lessons learned can be generalized to other developing and industrialized countries. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.  相似文献
