资源环境核算方法与问题研究

国际上现行的以国民收入核算为基础的国民核算体系是一种有缺陷并缺乏可持续发展调控能力的经济核算体系,应建立并推行包括自然资源与环境核算在内的新型国民核算体系,资源环境方法是在现有国民经济核算体系的基本框架上进行扩展和调整,具有非常积极的意义和优点,但实施起来还存在一定问题.     

An Unconditional Asset-Pricing Test and the Role of Firm Size as an Instrumental Variable for Risk

In an intertemporal economy where both risk (stock beta) and expected return are time varying, the authors derive a linear relation between the unconditional beta and the unconditional return under certain stationarity assumptions about the stochastic process of size-portfolio betas. The model suggests the use of long time periods to estimate the unconditional portfolio betas. The authors find that, after controlling for the betas thus estimated, a firm-size proxy, such as the logarithm of the firm size, does not have explanatory power for the averaged returns across the size-ranked portfolios.

Does Monetary Policy Have Asymmetric Effects on Stock Returns?

This paper investigates whether monetary policy has asymmetric effects on stock returns using Markov-switching models. Different measures of a monetary policy stance are adopted. Empirical evidence from monthly returns on the Standard & Poor's 500 price index suggests that monetary policy has larger effects on stock returns in bear markets. Furthermore, it is shown that a contractionary monetary policy leads to a higher probability of switching to the bear-market regime.     

中国金融环境与碳市场发展的关联度及作用分析——基于G20背景

利用灰色系统理论及信息熵对金融环境特别是融资环境和碳市场的关联性进行分析,构建碳市场与金融环境指标体系,并对其关联度进行排序及指标甄别,结果表明:中国在建设碳市场的进程中,政策导向应依靠国内融资,国际资金只能作为辅助渠道;积极促进绿色债券、基金等股权债权的发展,比银行提供间接融资对碳市场的影响更加显著;金融机构信贷中真正用于低碳生产或投资的款项十分有限,政府只需对信贷结构稍加优化,向低碳领域转移,便可对碳市场起到明显的杠杆作用.     

Excess Asset Reversions and Shareholder Wealth

The ownership of pension assets in a defined benefit pension plan is an unresolved issue in corporate finance. The issue is important because it defines the appropriate investment policy for a pension fund. In this paper, we summarize the ownership debate in the form of two mutually exclusive theories. We then focus on a recently popular event in pension finance, excess asset reversions. Our paper demonstrates the valuation effects associated with this event in a stochastic dominance framework. Under certain conditions, a reversion constitutes an expropriation of wealth from the participants and beneficiaries of the plan to the firm. Using data provided by the Pension Benefit Guaranty Corporation and the Center for Research in Security Prices tape, we examine the returns to the shareholders of 58 companies which conducted excess asset reversions between 1980 and 1984. Our results show that large abnormal returns accrued to these shareholders around the time of the reversion. These findings have implications both for the appropriate investment policy of pension funds and for public policy with respect to plan terminations.     

从时间维度界定经济法调整对象的科学性--"增量利益关系论"评介

现有主要经济法理论,是从主体维度的"公私二元结构假设方法论"来考察经济法的调整对象.经济法产生的现代性,要求从时间维度的"传统现代部门法二元结构假设方法论"来界定其调整对象."增量利益关系论"是从时间维度来界定调整对象的.从时间维度来界定调整对象,经济法就可以真正从调整对象上与传统部门法区别开来,进而彰显经济法蕴含的社会整体经济效益价值.

Federal Deposit Insurance,Regulatory Policy,and Optimal Bank Capital*

This paper seeks to explain the combination of explicit and implicit pricing for deposit insurance employed by the FDIC. Essentially, the FDIC sells two products—insurance and regulation. To span the product space, it must and does set two prices. We argue that the need to establish regulatory disincentives to bank risk-taking is the heart of the controversy over the adequacy of bank capital and that the ability to close risky banks before exhausting their charter value (i.e., the value of their right to continue in business) stands at the center of these disincentives and in front of the FDIC's insurance reserves.
