A General Model of the Behavioral Response to Taxation

This paper generalizes the standard model of how taxes affect the labor-leisure choice by allowing individuals to change both their labor supply and avoidance effort in response to tax changes. Doing so reveals that the income and substitution effect of taxes depend on both preferences and the avoidance technology. Econometric analysis will not in general allow one to separately identify the two influences, unless one can specify observable determinants of the cost of avoidance. The effective marginal tax rate on working must be modified by the addition of an avoidance-facilitating effect, which measures how the cost of avoidance changes with higher income. This model provides a conceptual structure for evaluating to what extent, and in what situations, the opportunities for tax avoidance mitigate the real substitution response to taxation.

The U.S. Motion Pictures Industry: An Empirical Approach

We hypothesize that the U.S. motion pictures industry is structured so that star presence increases box office receipts and (less so) admissions, but places Ricardian limits on the output of blockbusters. The few dominant studios (majors) rely on a modified star system to generate supra-normal box office by stimulating admissions at exhibitors. Rising costs (from stars and their promotion) are required for rising revenues; that is, the majors gain revenue only at higher costs. Although the industry has unique features, the empirical results are surprisingly relevant to other industries.     

Parametric,semiparametric, and nonparametric estimation of characteristic values within mass assessment and hedonic pricing models

Parametric estimators, such as OLS, attain high efficiency for well-specified models. Nonparametric estimators greatly reduce specification error but at the cost of efficiency. Semiparametric estimators compromise between these dual goals of efficiency and specification error. Semiparametric estimators can assume general forms within classes of functional forms. This paper applies OLS, the kernel nonparametric regression estimator, and the semi-parametric estimator of Powell, Stock, and Stoker (1989) to a data set, which should, based on theory and previous empirical work, yield positive coefficients. The semiparametric estimator, on average, displayed the performance most consistent with prior expectations followed by the nonparametric and parametric estimators. In addition, the paper shows how the semiparametric estimator can provide insights into the form of misspecification and suggest data transformations.

基于生命周期的虚拟企业知识活动分析及其伙伴选择过程研究

随着新经济的到来,知识越来越成为企业快速响应市场机遇和获取竞争优势的最短缺资源。而企业自身知识资源的有限性使企业越来越多地采用虚拟企业的高级形态——知识联盟型虚拟企业来弥补企业知识资源的不足以快速响应变化的市场需求。首先对知识联盟型虚拟企业的知识缺口类型进行研究和划分,然后分析并描述虚拟企业生命周期各阶段的知识活动;在此基础之上,探讨虚拟企业组建阶段考虑知识要素的伙伴选择过程;最后,针对不同的知识缺口,提出伙伴选择过程的评价指标体系设计中应考虑的知识性因素。

纳税遵从的国际借鉴及其在我国的适用探讨

纳税人的遵从程度直接影响税法实施的有效性,影响税款流失程度。在我国现阶段,分析导致纳税人不遵从的因素,制定相应的激励机制,提高纳税遵从度,对税务机关正确行使税务管理权,有效遏制税款流失有着现实的意义。     

论“公正”重于“关护”———对中国就业弱势群体税收支持政策的哲学反思

随着我国就业弱势群体的出现,财政部和国家税务总局陆续出台了一系列促进就业的税收政策,但由于这些税收政策在“公正”与“关护”两个基本原则运用上存在侧重点的偏差,导致这些政策的作用效果并不明显。“公正”与“关护”同属人类伦理学理论资源中的两个基本道德诉求。在就业弱势群体税收支持政策制定中,两者缺一不可、互相关联,但从国家宏观就业指导方针、道德原则的稳定性、持久性以及普遍性的角度看,应该坚持“公正”重于“关护”。
