执政经济成本的效益测评

执政是要支付成本的。执政经济成本的高低与执政的业绩有很大联系。“提高执政效率”是党的十六届四中全会《决定》中的一个重要思想。要提高执政效率,就必须考察执政的成本与效益之间的关系,开展对执政的经济成本效益及其测评方法的研究。     

Preliminary test estimators of the parameters of simple linear model with measurement error

In this paper, we discuss the properties of preliminary test estimators (PTE) of the parameters of simple linear model with measurement error (ME model) when the slope of the linear model is suspected to be zero. Expressions of the bias, MSE and efficiencies are obtained under conditional as well as unconditional situations with known reliability coefficient. Conditional model results are compared to the standard model without measurement error. We also provide the unconditional model analysis in finite samples. Asymptotic theory under local alternatives is developed when the variance of measurement error or the ratio of the variance of the model error relative to the variance of the measurement error is known. Asymptotic expressions of bias and MSE of the estimators along with their efficiencies are obtained. In every case, it is shown that the measurement error tend to increase the variability of the estimators compared to the estimators without measurement error. Graphs and tables are provided to see these results and to determine optimum level of significance for minimum guaranteed efficiency. Received October 2001 RID="*" ID="*"  A. K. Md. E.

A two-stage stratified Warner’s randomized response model using optimal allocation

This paper applies Kim and Wardes (2004) stratified Warners randomized response model to Mangat and Singhs (1990) two-stage randomized response model. The proposed stratified randomized response model has an optimal allocation and a large gain in precision. Hence, the estimator based on the proposed method is more efficient than Kim and Wardes (2004) and Mangat and Singhs (1990) estimators under the conditions presented in both the case of completely truthful reporting and that of not completely truthful reporting by the respondents.     

黑龙江省中小企业融资的一种新思路

中小企业对国民经济的重要性已为各界所共识,促进中小企业发展的各种措施也在讨论和实施中,而在中小企业发展中遇到的最主要的问题--融资难问题却始终没有得到有效解决.黑龙江省中小企业由于历史、地理以及其自身原因,融资难问题尤其突出.相比银行信贷、上市融资,融资租赁是一种非常适合中小企业的融资方式.

对会计信息失真的辨证思考

对会计信息失真要客观辨证地认识，失真是绝对的而真实性是相对的。治理会计信息失真是一项系统工程，一是要消除会计信息失真产生的内部原因，二是要改变会计信息失真产生的外部环境条件。     

The subjective expected utility hypothesis and revealed preference

Summary A choice behavior of a decision maker is said to satisfy the subjective expected utility hypothesis if there exist a utility and a subjective probability such that a decision maker chooses acts with the highest expected utility. We present a revealed preference characterization of choice behavior that is consistent with the subjective expected utility hypothesis. Our result applies to any state space and compact sets of prizes and observations (either finite or infinite).
