Liquidity shocks and equilibrium liquidity premia

We study an equilibrium in which agents face surprise liquidity shocks and invest in liquid and illiquid riskless assets. The random holding horizon from liquidity shocks makes the return of the illiquid security risky. The equilibrium premium for such risk depends on the constraint that agents face when borrowing against future income; it is insignificant without borrowing constraint, but can be very high with borrowing constraint. Illiquidity, therefore, can have large effects on asset returns when agents face liquidity shocks and borrowing constraints. This result can help us understand why some securities have high liquidity premia, despite low turnover frequency.     

假转让技术真转让国有资产

国有资产流失长期以来一直是困扰国企改革和发展、政府进行国有资产管理的重大问题。近年来,国有资产的流失更是呈加剧之势头,一些人打着“改制”、“转制”的幌子,大肆鲸吞国有资产! 本期刊登的两个案例,都是关于此类现象的。这些国有资产流失的形式,大都被披上了合法的外衣。第一个案例,当事者通过“合同”的形式,猫鼠同窝,合同双方恶意串通,将国有资产无偿“转让”;第二个案例中,当事者串通中介,虚假评估,以实现廉价“收购”国有资产及避税的企图。涉及金额之巨大,手法之巧妙,触目惊心。 毫无疑问,这样的交易背后往往隐藏着惊人的腐败,隐藏着贪污、受贿、行贿、玩忽职守等严重的违法犯罪。审计人是国有资产的卫士,顺着此类“交易”的蛛丝马迹,层层剥茧,从而抓住了作奸犯科者的狐狸尾巴,把侵吞国有资产案件大白于天下。

Noise Trading and the Management of Operational Risk; Firms,Traders and Irrationality in Financial Markets*

abstract Efficient market models cannot explain the high level of trading in financial markets in terms of asset portfolio adjustment. It is presumed that much of this excessive trading is irrational ‘noise’ trading. A corollary is that there must either be irrational traders in the market or rational traders with irrational aberrations. The paper reviews the various attempts to explain noise trading in the finance literature, concluding that the persistence of irrationality is not well explained. Data from a study of 118 traders in four large investment banks are presented to advance reasons why traders might seek to trade more frequently than financial models predict. The argument is advanced that trades do not simply occur in order to generate profit, but it does not follow that such trading is irrational. Trading may generate information, accelerate learning, create commitments and enhance social capital, all of which sustain traders' long term survival in the market. The paper treats noise trading as a form of operational risk facing firms operating in financial markets and discusses approaches to the management of such risk.     

The dynamics of moonlighting in Russia1

This paper uses the Russian Longitudinal Monitoring Survey (RLMS) to analyse the dynamics of moonlighting by the working‐age population. We find that moonlighting is transitory and that a desire to switch jobs expressed in the past is positively related to moonlighting in the present and to actual job changes in the future. We also find that workers who moonlighted as self‐employed in the past represent 26.5 percent of the new self‐employed. These results suggest that moonlighting in Russia can be seen as an effective incubator for setting up new self‐employed businesses, thereby providing long‐term benefits for the economy.

Improved estimation of portfolio value‐at‐risk under copula models with mixed marginals

Portfolio value‐at‐risk (PVAR) is widely used in practice, but recent criticisms have focused on risks arising from biased PVAR estimates due to model specification errors and other problems. The PVAR estimation method proposed in this article combines generalized Pareto distribution tails with the empirical density function to model the marginal distributions for each asset in the portfolio, and a copula model is used to form a joint distribution from the fitted marginals. The copula–mixed distribution (CMX) approach converges in probability to the true marginal return distribution but is based on weaker assumptions that may be appropriate for the returns data found in practice. CMX is used to estimate the joint distribution of log returns for the Taiwan Stock Exchange (TSE) index and the associated futures contracts on SGX and TAIFEX. The PVAR estimates for various hedge portfolios are computed from the fitted CMX model, and backtesting diagnostics indicate that CMX outperforms the alternative PVAR estimators. © 2006 Wiley Periodicals, Inc.

第三部门的发展与政府改革的互动

第三部门的兴起被认为是二战以来的世界社会范围内一场重要的变革,对此,有学者评价认为,“我们是置身于一场全球性的‘社团革命’之中,历史将证明这场革命对20世纪后期世界的重要性丝毫不亚于民族国家的兴起对19世纪后期世界的重要性。”[1]考察建国以来我国第三部门的发展历程
