Arrow's equivalency theorem in a model with neoclassical firms

Summary. In this paper we consider a two-period general equilibrium model with uncertainty and real assets as financial instruments. The novelty of the analysis is that real assets are the stocks of neoclassical firms, so that both returns and yields depend on anticipated spot goods prices (and, of course, the yield matrix may change rank with prices). Assuming that financial markets are potentially complete, we establish generic existence of financial equilibrium and prove that there exists a dense set of economies such that financial equilibria are efficient.Received: 19 April 2001, Revised: 23 April 2003, JEL Classification Numbers: C60, D51, G10, D60.I am extremely grateful to Dave Cass for drawing my attention to this problem and inspiring me to work on it as well as for many stimulating discussions.

金融自由化与金融监管体制改革--以日本为实例的分析

日本金融体系的异常行为是造成日本泡沫经济的直接原因,而1985年旨在实现金融自由化的金融改革却从以下两个方面促成了金融体系的异常行为：自由化的不平衡导致了利率体系的扭曲,为经济实体对房地产、股票等虚拟资产的投机资金需求方面起到了促进作用;自由化引发的金融机构的经营目标的改变,使对贷款的审批、稽核力度下降,又从资金供给方面支持了经济实体的投机行为．对于自由化带来的问题,日本进行了监管体制改革,并给我们提供了经验和教训。

Financial Sector Risk and the Stock Returns: Evidence from Tokyo Stock Exchange Firms

We investigate whether the activity of financial firms creates value and/or risk to the economy within the asset pricing framework. We use stock return data from nonfinancial firms listed in the first section of the Tokyo Stock Exchange. The value-weighted index that is solely composed of nonfinancial firms is augmented with the index of the firms from the financial sector, and we estimate multivariate asset pricing model with these two indices. We note that our procedure can simultaneously take into account the cross-holding phenomena among Japanese firms, especially between the financial sector and the nonfinancial sector. Our augmented index model performs well both with cross-sectional Fama and MacBeth regression test and GMM test. Our two index model with additional Fama and French's HML factor can capture cross-sectional variations of the returns of sample portfolios better than the original Fama and French model can, when measured by Hansen and Jagannathan distance measure. We find that this additional new sector variable can be a substitute for Fama and French's size factor, but not related to the bond index return. This variable has similar factor characteristic as money supply growth or the term structure, but the latter variables contain more information than the former. Morever, our financial sector model helps explain the return and risk structure of Japanese firms during the so-called bubble period.     

特殊会计事项对编制现金流量表的影响

销售商品提供劳务收到的现金和购买商品接受劳务支付的现金这两个会计项目的填制应从权责发生制调整到现金收付制,并且要考虑到一些特殊项目的影响,对其作适当的调整;"内部往来"等表外科目在编制现金流量时应分成三部分经营活动、投资活动、筹资活动,然后用总额法兼净额法进行调整.     

Sound Money and Sound Financial Policy

Anna Schwartz has long promoted a policy of stable money. She also has advocated sound financial policy. The financial environment, according to her work, is strongly influenced by the degree of aggregate price stability. In this article historical evidence for the U.S. is presented that shows a strong association between aggregate price movements and measures of financial distress. Even in an environment of aggregate price stability in the face of shocks, however, a monetary authority should follow the financial policies of a lender of last resort as advocated over a century ago by Walter Bagehot—to promote adequate funds to allay the public's demand for means of payment in the face of a real financial crisis. Other circumstances involving asset market reversals that Schwartz calls pseudo crises should not be the subject of the monetary authorities' actions.

区域金融生态环境差异与经济增长效率

本文利用实证分析的方法，选取金融生态环境不同的地区样本，运用定量指标对影响金融生态环境的诸多要素进行深入对比分析，指出金融不是孤立的，它内生于经济社会的大环境之中。良好的金融生态环境能够营造“资金洼地”，从而促进当地的经济增长；不良的金融生态环境，往往造成巨额的不良资产，导致金融资源的低效配置，不利于经济的发展壮大。因此，改善金融生态环境、促进经济增长，实现经济可持续发展，必须从影响金融生态环境的不同因素及不同层面上加以完善与改进，必须要发挥政府的主导作用，依靠法律的、经济的、文化的乃至全社会的共同努力培育良好的金融生态环境。     

金融中心评价指标体系研究

本文在综述国内外关于金融中心评价指标体系的基础上，分析了影响金融中心形成和运行的因素，依据国际金融中心的形成和运行具有较高相关度的原则，构建了包括经济环境、金融市场、金融机构和金融制度四方面内容的评价指标体系，利用2004年东京、新加坡、香港、北京、上海、广州和深圳七个城市的数据，依据层次聚类分析方法对这些城市所处的层次进行定位：北京、广州和深圳成为一类，为金融中心的初级阶段；上海成为第二类，为国内金融中心阶段；香港和新加坡成为一类，是区域国际金融中心；东京处于最高阶段．是真正的国际金融中心。最后对这些城市的发展前景进行了预测。
