浅析房地产广告的社会责任问题

随着住房改革的深入以及国家政策层面的支持,房地产开发投资逐年递增,发展了房地产广告,也出现了很多社会责任方面的问题。本文通过总结其中一些问题,提出了解决这些问题的具体策略。     

水域巡视中现场执法方式及取证多样化初探

本文通过对海事水域巡视中现行执法模式及取证方法进行分析,得出其存在的不足。并在此基础上,结合实际提出了改进方案。     

The Decline of Antitrust Enforcement

American Antitrust policy has abandoned tight restrictions on mergers and on a variety of business practices, such as vertical restraints indistribution. I argue that the change is permanent for three reasons: 1)rising skepticism about government intervention generally, 2) lack ofdeleterious effects from the new policy, and 3) increasing irrelevance ofantitrust in global markets. Due process considerations will reinforce thechange in policy. New technologies may, however, revive traditionalantitrust concern with price fixing.     

Innovation performance across Europe

The innovation performance of firms is primarily determined by their own innovative activities and the interaction with their innovation-related environment. This environment typically differs among countries. We assess empirically these differences on firms' innovation performance. To that end we first estimate the relationship between an aggregate innovation input measure and an aggregate innovation output measure, thereby explicitly controlling for structural differences between countries. We then consider the extent to which firms located in a particular country perform better or worse than this estimated benchmark performance. The analysis is based on a panel dataset that we have constructed from Eurostat's first and second Community Innovation Survey. In order to control for possible data contamination we employ an outlier-robust estimator. It appears that among the fourteen countries considered Italy, Germany and Ireland offer an environment that facilitates most the transformation of innovation-related inputs into commercial outputs while the environment in Denmark is the least facilitating.     

知识产权保护能促进经济增长吗？--基于中国省级面板数据的实证分析

在Ginarte-Park方法的基础上,考虑到处于司法转型期的发展中国家的执法力度和立法强度,建立知识产权保护强度指标体系,将中国30个省、自治区、直辖市知识产权保护水平量化。接着运用面板数据分析方法,以人均实际GDP对数为被解释变量,以知识产权保护强度为解释变量,通过实证分析验证了我国加强知识产权保护与经济增长的关系,证明了中国的知识产权保护水平与经济增长之间的显著正相关关系。然后对东中西部地区分别进行实证分析,绘制了异常经济增长与知识产权保护强度的散点图,来作为稳健性检验的一部分。并通过对变量的相关系数矩阵图的分析,初步探讨了知识产权保护促进经济增长的具体路径。结果表明,在控制了时间效应后,知识产权保护强度能够解释省份个体效应的37.4%。     

Optimal Self-Reporting Schemes with Multiple Stages and Option Values

We consider a model of optimal law enforcement where sanctions can be reduced for self-reporting individuals. We distinguish between a first self-reporting stage before the case is investigated and a second one where the criminal is detected, but not yet convicted. Since we assume that violators have private information in both stages, fine reductions for self-reporting individuals lead ceteris paribus to a higher violation frequency. Nevertheless, we show that fine reductions should be granted in both stages. We characterize the connection between the two fine reductions in the optimal policy and relate our results to self-reporting schemes observed in reality.     

Escalating penalties for repeat offenders: a note on the role of information

The severity of the sanction for a given offense is often determined by the offense history of the offender. We establish that this policy can be welfare-maximizing if individuals are imperfectly informed about the magnitude of the sanction. Imperfect information distorts individuals’ perception of the expected sanction of the first offense. Once detected, individuals learn about the sanction applicable to their act, making this argument less relevant for consecutive offenses.      

美国科技政策学研究计划进展分析与启示

美国国家科学基金会于2006年设立了科技政策学研究计划（SciSIP）,经过十多年发展,在数据与方法研究以及共同体建设方面取得了重要进展。聚焦于SciSIP计划及其历年项目成果,对SciSIP计划发展历程进行总结,对SciSIP计划的研究成果和面临的挑战进行分析,以期为中国推进科技政策学研究及“科技政策学”这一新兴学科建设提供建议。
