二元财政的制度变迁：基于路径依赖的视角

植根于二元经济结构的二元财政制度总是执行有利于城镇部门发展，而且有损于农业部门发展的财政税收政策。这不仅造成了农村居民的长期贫困，而且还持续拉大城乡差距。基于新制度经济学的制度变迁分析结果显示，二元财政的制度安排内含自我增强机制，其变迁具有明显的路径依赖特征，所以，农村居民的贫困必然具有长期性，城乡差距也会持续拉大。因此，必须根据中国经济现实，对二元财政制度采取边际调整的改革措施和借助市场化的手段改善其赖以存在的经济环境，方可在长期内从整体上推动二元财政制度变迁，实现城乡平等的财政制度。     

Corporate Diversification and Firm Value: Evidence from Post‐1997 Data*

In 1997, SFAS 131 established a new segment‐reporting standard for US public companies. Using measures of diversification based on the diversity in segment‐industry characteristics and controlling for endogeneity of the diversification decision, we document a diversification premium in our post‐1997 period. We find significant positive effects of cash flow diversity, leverage diversity and profitability diversity on excess value, consistent with the efficient internal capital market hypothesis. We also find that the size of the diversification premium in the post‐1997 data is negatively correlated with the degree of diversification and positively correlated with firm size. In contrast, we find that the pre‐1998 data typically generates a diversification discount, but the effect is statistically less significant when endogeneity is controlled for. Thus, the diversification discount documented in earlier studies can be an artifact of the pre‐1998 data or a failure to control for endogeneity.     

论国际收支失衡对我国货币政策有效性的影响

自1993年以来,我国国际收支一直保持着连年顺差,特别是在近期内国际收支差额的增长速度更是令人惊叹。而我国国际收支的连年顺差必将使央行货币政策的有效性受到冲击。为缓解国际收支失衡、提高我国货币政策的有效性,本文在借鉴发达国家经验的基础上提出了几点相关的政策建议。

Who Believes the Hype? An Experimental Examination of How Language Affects Investor Judgments

This paper investigates the effect of vivid language on investor judgments. Recent research finds that investor judgments are significantly influenced by disclosure tone (positive versus negative). Holding tone constant, we investigate investors’ reactions to vivid versus pallid information. Drawing on theories from psychology, we predict that investors will be sensitive to the differences between vivid and pallid language when the underlying information is preference inconsistent, but not when the information is preference consistent. Results of two experiments support our prediction. Vivid language significantly influences the judgment of investors who hold contrarian positions (i.e., short investors in a bull market and long investors in a bear market). Interestingly, vivid language has limited influence on the judgment of investors who hold positions consistent with the general tenor of the market. Our results provide evidence regarding when vividness matters and when it does not in financial contexts, thereby contributing to both psychology and a growing literature on disclosure tone in financial reporting. In addition, our results also speak to concerns raised by regulators and academics asserting that vivid language can inflate bubbles and incite panics.
