政府投资项目代建制的财政和财务管理工作探讨

代建制作为一种新的建设模式,克服了“投、建、管、用”四位一体的政府投资工程管理模式所带来的非专业化、低效率、低质量等弊端,通过专业化、集中化和市场化的管理,实现投资控制,保证质量和工期。但代建制是有相应的配套制度作保障的,如果制度不配套,依然会存在风险。在新的政府协调干预机制下———建筑工务局的成立,探讨如何搞好代建制的财政财务管理工作。     

补贴概念与效果

补贴是一个相当复杂的议题,其复杂性不仅表现在概念上,也表现在它可能产生的效果上。补贴可能增加也可能降低其受体的利润水平;可能对国际贸易产生扭曲效果,其影响也可能仅限于国内;可能有助于政府实现其意欲达成的目标,也可能背离其初衷;可能增加或降低政府收益,也可能无影响。把补贴宽泛地界定为有可能在短期、中期或长期对其受体的利润水平产生影响的政府作为(或不作为),有助于使决策者把关注重点转向补贴效果,从而有利于其做出应否维持、增加、减少或消除特定补贴的判断。     

PASSPORT OPTIONS

We relate the theory of passport options with general principles from martingale theory as well as with the theory of Bessel processcs. The calculation of the price of a passport option leads to an equality between two norms on continuous martingales. We also solve the discrete time case for passport options.     

Liquidity Pools, Risk Sharing, and Financial Contagion

This paper reevaluates the Allen–Gale (2000) analysis of interbank deposits to explain financial contagion. This paper modifies the pecking order of asset liquidation developed in Allen–Gale, which is essential in fragility analysis. Furthermore, we also provide a claim structure called liquidity pool that can both achieve risk sharing and prevent financial contagion across regions when asymmetric information about bank assets is absent. This model can partly explain why bank panics reduced substantially after the founding of the Fed and the role of IMF in regional financial crises.     

A Benchmark Approach to Filtering in Finance

The paper proposes the use of the growth optimal portfolio for pricing and hedging in incomplete markets when there are unobserved factors that have to be filtered. The proposed filtering framework is applicable also in cases when there does not exist an equivalent risk neutral martingale measure. The reduction of the variance of derivative prices for increasing degrees of available information is measured. 1991 Mathematics Subject Classification: primary 90A09; secondary 60G99; 62P20 JEL Classification: G10, G13     

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。     

武汉金融安全区模式设计与研究

金融安全与稳定直接关系到一个国家或地区的经济安全与社会稳定。一个地区 ,在突出的支付风险得以逐一化解之后 ,适时启动创建金融安全区工程 ,并以此全面提高金融监管水平 ,实现区域金融业持续稳健发展已经成为当前我们面临的重要课题。本文在论证武汉市开展创建金融安全区的必要性和可行性的基础上 ,提出了构建以武汉金安指数为核心的指标监测体系、具体创建规划以及相应运行规程。     

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.
