论企业伦理与市场效率

新古典经济理论及新制度经济理论将伦理道德之维从微观主体应有的特性中抽去,使企业组织成了不涉道德的“纯粹理性人”。然而,理性人的理性经济行为却不能保证市场效率的提高,相反,却加大了社会成本。伦理道德是企业组织必备的品质,理性应建立在道德的基础之上,使道德对企业行为具有验前的约束力,市场才能更有效率。

Multiple Dimensions of Cigarette Smoking and Responsiveness to Cigarette Price Changes in Taiwan

This study investigates how smokers respond to both short- and long-run changes in the price of cigarettes in multiple dimensions of smoking behavior. Using a sample of males from a national longitudinal survey in Taiwan, we estimated the demand for cigarettes under both short- and long-run specifications using a quality-purged price index. We found a modest short-run price elasticity of demand for cigarettes and a long-run elasticity of demand that did not significantly exceed the short-run elasticity. We also found that smokers responded to higher cigarette prices by smoking each cigarette more fully without changing their choices of tar and nicotine content to compensate for reduced cigarette consumption.

When are two step estimators efficient?

Kruskal's theorem is used to provide simple and elegant alternative derivations of the efficiency of some two step estimators (2SE) for models containing anticipated and unanticipated variables. Several new results are established: 2SE is not efficient for a structural equation with current and lagged values of both anticipated and unanticipated variables; 2SE is always efficient for the parameter associated with the current unanticipated variable, and for the parameter associated with the lagged unanticipated variable if there is no lagged dependent variable in the expectations equation; the inclusion of additional regressors in the structural equation and contemporaneous correlation of the structural and expectations errors can both be analysed in a straightforward manner; the single-equation generalized least squares estimator can be as efficient as the systems maximum likelihood estimator.     

Intransitive cycles: Rational choice or random error? An answer based on estimation of error rates with experimental data

The paper presents results from two new experiments designed to test between the rational choice hypothesis and the random error hypothesis for intransitive choice. Error probabilities and population shares for transitive and intransitive preference types are estimated from data collected in the first experiment. An unrestricted model (which treats intransitive patterns as true patterns) performs no better than a model that is restricted to transitive patterns. Analysis of the conditional distributions of choice patterns, using data from the second experiment, confirms more directly the main results of the first experiment: that observed intransitive choice patterns are due to random error.     

大学英语四级考试完形填空试题的考点效度分析

合理删词完形填空作为完形填空的一种形式,是根据教学或测试目的有意识地选择某些考点,不定距地删去一些词,要求学生根据上下文把空缺词一填补上。国内外许多研究表明,合理删词完形填空较其它完形填空信度与效度更高,是检测学生总体能力和综合能力的一个好办法。合理删词完形填空试题是大学英语四级考试中普遍使用的考试题型。从考点效度方面回顾与分析了历年大学英语四级考试完形填空试题。     

承袭与诘难：“经济人”假设之演化--兼论其对社会主义市场经济的适应性

"经济人"作为西方经济理论的一个基本假定,经历了一个在承袭中提炼、诘难中扩充发展的长期演化过程,其结果是不断地使之适应于西方经济理论研究的需要以及构成了其他经济分析的基础。西方经济学的"经济人"假设能否适应于社会主义市场经济,我们必须有一个客观的态度。     

论刑事和解中检察权的合理配置

检察机关的性质决定了在刑事和解中检察权的行使。检察机关应引入量刑建议权,建立暂缓起诉制度,完善非刑罚处罚措施,检察机关的监督职权决定了其不宜行使建议撤案权。
