我国现行融资制度功能的理论及实证分析

内生于经济增长的融资制度应具备筹资功能、降低交易成本功能、价格发现功能、流动性功能和风险转移功能等五方面的功能.我国现行融资制度基本能够有效地进行储蓄动员,但在向资本转化方面存在着一定的障碍;作为公共资源的政府融资仍然发挥着相当重要的作用,但金融市场对经济的促进作用有进一步弱化的趋势;在地区间和企业间存在着资源的逆配置现象,总体上资本的运用效率较低,而非正规金融发挥了不可或缺的作用;严格的利率管制使中介的价格发现功能几乎没有,而市场的价格发现功能一直较弱;此外,存在较高的交易成本,流动性水平整体较低,风险转移功能也相对缺乏.

The stock market effects of a securities transaction tax: Quasi-experimental evidence from Italy

In the aftermath of the financial crisis, in several countries new levies on the financial sector have been proposed and in some cases implemented. We focus in particular on the recent introduction of a securities transaction tax (STT) in Italy. A peculiarity of the Italian STT is that it only concerns stocks of corporations with a market capitalization above € 500 million. We exploit this feature via a differences-in-differences approach – comparing taxed and non-taxed stocks before and after the introduction of the tax – and via a regression discontinuity design – comparing the performance of stocks just above the threshold with those just below. Focusing on the regulated market, we find that the new tax reduced liquidity, but it left transaction volumes and returns substantially unaffected. There is also evidence – although not conclusive – that the tax increased volatility.

Private Information in Life Insurance,Annuity, and Health Insurance Markets

Economic theory predicts that private information on risks in insurance markets leads to adverse selection. To counterbalance private information, insurers collect and use information on applicants to assess their risk and to calculate premiums in an underwriting process. Using data from the English Longitudinal Study of Ageing (ELSA), this paper documents that differences in the information used in underwriting across life insurance, annuity, and health insurance markets attenuate private information to different extents. The results are in line with – and might help to reconcile – the mixed empirical evidence on adverse selection across these markets.
