Foreign Entry and Firm Advertising Intensity: Evidence from China

This paper investigates the determinants of advertising intensity at the firm level by focusing on the role of foreign entry. In a monopolistically competitive market with heterogeneous firms, we show that foreign entry affects the expected advertising intensity of domestic firms through its impact on the cost of resources, brand image, and productivity spillovers and its impact on firms’ exit behaviour. Then, using comprehensive firm-level data from China’s manufacturing sector between 2005 and 2007, we test this hypothesis and find that foreign entry significantly affects advertising intensity.

Valuing the Longevity Insurance Acquired by Delayed Claiming of Social Security

Individuals can claim Social Security at any age from 62 to 70, although most claim at 62. We show that expected present value calculations substantially understate both the optimal claim age and the losses resulting from early claiming because they ignore the value of the additional longevity insurance acquired because of delay. Using numerical optimization techniques, we illustrate that the optimal claim age is between 67 and 70. We calculate that the amount by which benefits payable at suboptimal ages must be increased so that a household is indifferent between claiming at those ages and the optimal combination of ages can be as high as 19.0 percent.     

核心企业合作能力影响供应链融资绩效的机理

核心企业在供应链融资中居于主导地位,融资风险更容易通过供应链进行传播扩散,因此核心企业的合作能力是供应链融资的关键。以"融资能力—融资中介—融资绩效"为理论研究框架构建核心企业合作能力,通过供应链网络整合影响供应链融资绩效的理论模型,并基于判别分析(Discriminant Analysis,DA)和模糊集定性比较分析(Fuzzy set Qualitative Comparison Analysis,Fs—QCA)对研究假设进行检验。研究结论如下:核心企业合作意愿与合作行为对提升供应链融资绩效具有正效应;供应链网络集成在核心企业合作能力与供应链融资绩效之间具有中介和调节作用;供应链网络外部集成能促进供应链融资绩效提升,且作为中介发挥核心企业合作能力在供应链融资中的积极作用;核心企业的合作意愿是决定供应链融资绩效的核心条件。     

卖方分析师佣金解绑改革与中国实践--基于MiFIDⅡ的思考

卖方分析师利益冲突问题损害了投资者利益以及市场稳定性。为提高分析师独立性,欧洲2018年出台的《欧盟金融工具市场指令Ⅱ》首次拆分了分析师的分仓佣金与研究费用。研究发现,该举措实施后,伴随着卖方研究质量提升、低质量分析师退出市场,分析师利益冲突问题得到缓解,促进了卖方服务内部化转型、买方研究加速形成以及投资者交易透明度的提升,但同时也带来了研报价格恶性竞争、市场信息环境受损、人才非优流动等负面影响。我国分析师佣金制度存在披露透明度不足、研究服务界定不明、佣金分配缺乏有效监管等问题,现阶段完全解绑佣金可能引发潜在风险,应采取相对柔性的改革思路。监管机构宜推动改革基金管理费用,塑造市场激励机制;券商应提升综合研究能力,推进业务模式转型,探索差异化发展之路。     

Institutional stock trading on loan market information

One of the most important developments in the corporate loan market over the past decade has been the growing participation of institutional investors. As lenders, institutional investors routinely receive private information about borrowers. However, most of these investors also trade in public securities. This leads to a controversial question: Do institutional investors use private information acquired in the loan market to trade in public securities? This paper examines the stock trading of institutional investors whose portfolios also hold loans. Using the Securities and Exchange Commission filings of loan amendments, we identify institutional investors with access to private information disclosed during loan amendments. We then look at abnormal returns on subsequent stock trades. We find that institutional participants in loan renegotiations subsequently trade in the stock of the same company and outperform trades by other managers and trades in other stocks by approximately 5.4% in annualized terms.

汇率调整是否能有效的改变贸易逆差呢?——从金融市场完善程度差异性的角度分析

随着全球失衡的加剧,作为世界主要贸易逆差国的美国希望通过敦促其逆差来源国货币升值的途径,来改善自己的贸易逆差。但是这一调整策略是否能够达到预期的结果呢?本文通过对美国的逆差来源国货币升值的绩效分析发现,货币升值能否改变失衡的局面取决于一国的金融完善程度。金融市场较为完善的国家对于汇率调整的敏感度更高,而金融市场较为不发达的国家则对于这种调整不甚敏感。中国受限于金融市场完善程度,导致人民币升值不能改善其国际收支失衡的现状,而美国也不会获得预期的收益。
