和谐社会中的政府形象与政府公关

政府公关是政府公共管理的重要内容。新时期里，加入WTO、政府职能转变、公共危机的频频出现以及构建和谐社会都迫切要求政府重塑自身形象。政府公关是重塑政府形象的重要途径，其主要任务包括树立全员公关的意识、树立“公众利益至上”的行政理念、有效处理各种信息、公开政府工作人员的有关情况等。     

浅析我国企业所得税改革——写在2007年“税合一”出台之际

2007年3月14日，提交全国人大审议的企业所得税法草案规定，将内外资企业所得税税率统一为25％，法定税率由33％降低了8个百分点。外资实际税率要从15％变成25％，内资要从33％下降到25％。大多数的声音是，这项政策对外资企业是一种公平合理的国民待遇，对内资企业则是一种重要的激励。这将会使市场竞争朝着更加公平的方向发展。本文通过对这项具有里程碑意义的税改政策出台的背景、影响等方面加以综合分析，并归纳整理了该政策出台后理论界、业界的不同观点，为新税制的发展提供了展望。     

Dissertation abstract: Reputational benefits of altruism and altruistic punishment

Recent studies in experimental economics have shown that many people have other-regarding preferences, potentially including preferences for altruism, reciprocity, and fairness. It is useful to investigate why people possess such preferences and what functional purpose they might serve outside the laboratory, because evolutionary and social learning perspectives both predict that cooperative sentiments should only exist if they bring benefits that outweigh the costs of other-regarding behavior. Theories of costly signaling suggest that altruistic acts may function (with or without intention) as signals of unobservable qualities such as resources or cooperative intent, and altruists may benefit (possibly unintentionally) from the advertisement of such qualities. After reviewing the theories that could potentially account for the evolution of altruism (Chapter 1), I test some predictions about cooperation derived from costly signaling theory. In Chapter 2, I show that participants in experimental public goods games were more cooperative when they had cues that they could benefit from having a good reputation, and that there was apparently some competition to be the most generous group member. Furthermore, in subsequent trust games, people tended to trust high public goods contributors more than low contributors. Chapter 3 failed to find evidence that granting high status to people makes them more likely to contribute to public goods or punish free-riders, but there was suggestive evidence that physical proximity to the experimenter affected contributions and punishment. In Chapter 4, I found that people tended to trust others who were willing to incur costs to punish those who free-ride on group cooperation provided that such punishment was justified, and men were more punitive than women. In Chapter 5, I show that women find altruistic men more desirable than neutral men for long-term relationships. Together, these results suggest that humans do treat altruism as a signal of willingness to be cooperative. These findings are discussed with respect to the adaptive design of cooperative sentiments as well as the current debate over group selection.

审计独立性的博弈分析

注册会计师的独立性是一种抽象的精神状态,它是通过注册会计师在特定制度安排下的利益选择表现出来的,本文着眼于此,通过建立特定制度下注册会计师行为的博弈模型,从审计收费、注册会计师承担的责任、注册会计师不独立获得的额外好处、管理当局对注册会计师的处罚等方面分析注册会计师的独立性。     

The religious factor in private education

We quantify the religious factor in private education in the United States by calibrating a political economy model of school choice—among public, private-nonsectarian and subsidized religious schools—in which parents differ in their incomes and in their preferences for religious education. This shows strong latent demand for religious schooling, conditioned on current subsidized tuition levels in parochial schools, which is suppressed by the need to “pay twice” for private education. Applying the results of the calibration to gauge the effect of means-tested school voucher programs on religious and nonsectarian private enrollment, we find that when the amount of the voucher is relatively small, including subsidized religious schools in such programs is necessary for providing low-income families effective access to private education.     

改革地方公共管理的权利路径:巴西的经验

巴西的“公共管理与公民权”项目于1996年建立,其目的是发现和宣传由巴西次国家级政府在服务供给上的创新行为。这些创新时巴西的公民权建设产生了直接的影响。本文根据巴西的经验初步分析了从“权利”的路向改革公共管理,扩大其他机构和公民社会参与的可能性。
