债务上限与信评机构的政治悖论性选择

金融危机后,以危机推手著称的美国信评机构因群体性道德风险和贩卖劣质公信力而备受国际谴责.为此,三大机构不同程度地修订了主权信用评级规则,并自2010年下半年以来,联袂发布了美国主权信用评级的负面意见,尤其是2011年轮番下调美国主权信用评级前景展望至负面,希望借此塑造其公正、客观的商业形象.但是,三大机构的政治附属物属性决定了三大机构发布的美国主权信用评级负面意见,本质上是一场政治逻辑与资本逻辑的较量,更多展现为一种政治博弈的需要,并使自己陷入了债务上限与主权信用评级的政治悖论困境.

Cumulative prospect theory and the St. Petersburg paradox

Summary. We find that in cumulative prospect theory (CPT) with a concave value function in gains, a lottery with finite expected value may have infinite subjective value. This problem does not occur in expected utility theory. The paradox occurs in particular in the setting and the parameter regime studied by Tversky and Kahneman [15] and in subsequent works. We characterize situations in CPT where the problem can be resolved. In particular, we define a class of admissible probability distributions and admissible parameter regimes for the weighting- and value functions for which finiteness of the subjective value can be proved. Alternatively, we suggest a new weighting function for CPT which guarantees finite subjective value for all lotteries with finite expected value, independent of the choice of the value function. Some of these results have already been found independently by Blavatskyy [4] in the context of discrete lotteries.Received: 14 October 2004, Revised: 6 May 2005, JEL Classification Numbers: C91, D81.We thank Pavlo Blavatskyy and Thorsten Hens for their helpful remarks regarding our paper.

Firms’ Compliance to Environmental Regulation: Is There Really a Paradox?

It has often been claimed that firms’ compliance to environmental regulations is higher than predicted by standard theory, a result labeled the “Harrington paradox” in the literature. Enforcement data from Norway presented here appears, at first glance, to confirm this “stylized fact”: firms are inspected less than once a year, detected violators are seldom fined, but still, serious violations seem relatively rare. However, at a closer look, the pattern seems less paradoxical: enforcement of minor violations is lax, but such violations do flourish; serious violations, on the other hand, are subject to credible threats of harsh punishment, and such violations are more uncommon. This seems quite consistent with predictions from standard theory. We argue that the empirical existence of the Harrington paradox is not well documented in the international literature. The claim that firms’ compliance with environmental regulations is generally higher than predicted by standard theory should thus be regarded as a hypothesis rather than an established fact.     

基于中国经验重构新新贸易理论的分析框架

异质性企业贸易模型是新新贸易理论的基本分析框架,该模型从企业生产率异质性角度分析企业出口的决定因素,得到企业拥有高生产率是保证其出口的重要条件,从而出口企业的生产率要高于内销企业的结论。不过,对中国企业的经验研究却发现,出口企业的生产率未必高于内销企业,甚至低于内销企业,即中国出口企业存在"生产率悖论"。目前,对于"生产率悖论"的研究主要集中于经验分析,并没有提出一个合理解释该现象的理论模型。文章从扩展异质性企业贸易模型的角度,建立了一个旨在解释"生产率悖论"的数理模型。尽管该模型对"生产率悖论"具有解释作用,但是并没有否定生产率对企业出口的作用。文章进一步使用较新的LP方法计算了中国制造业企业的生产率并运用统计法检验了出口企业"生产率悖论"的存在性,检验结果表明中国制造业大部分行业不存在"生产率悖论"。总之,文章研究认为生产率只是企业出口的一个必要条件而不是充分条件,这也重新构建了新新贸易理论的分析框架。     

中国服务业发展悖论——基于“两波”发展模式的研究

本文借鉴最新文献对服务业发展规律的测度方法,用中国1952—2010年的地区面板数据对我国服务业比重变化的长期规律和阶段性特征进行了测度,结果认为:宏观国家层面上,我国服务业比重的变化确实有悖于世界经济整体服务化的趋势;但在地区层面上,我国服务业比重与人均GDP的关系基本符合"服务业比重随经济发展不断上升"的普遍规律,所谓经济服务化的"中国悖论"在地区层面上并不存在;对服务业发展的阶段性特征和地区差异进行分析发现,我国大部分地区仍然处于以传统服务业为主的第一波发展阶段,只有少数地区进入了以现代服务业发展为主导的第二波。文章最后对我国服务业发展规律的成因进行了一般分析和实证检验。

Supply‐ versus Demand‐Side Policies in the Presence of Carbon Leakage and the Green Paradox

We consider a climate coalition that seeks to reduce global emissions in the presence of carbon leakage and resource exhaustibility. We show that a credible announcement of future unilateral supply‐side policies delays foreign emissions, and we derive the optimal combination of consumer taxes and producer taxes when we consider leakages from free riders, both within periods and across periods. The tax shares generally differ over time. A decline in the present value of the social cost of carbon over time supports a time path where the consumers’ tax share of the total carbon tax also declines over time. We illustrate our findings with a numerical model.
