经济周期、融资约束与流动性管理--基于交通运输业的实证分析

经济周期波动对交通运输企业的流动性管理有显著影响。经济周期通过产品市场渠道、资本市场渠道影响企业的外部融资成本,从而导致企业在经济衰退期面临更加严峻的融资约束,并传导到流动性管理行为。与其他行业相比,我国交通运输企业的流动性管理整体上受经济周期的冲击更为显著。因此,交通运输企业必须实施有效的周期性流动管理,政府部门也应该实施周期性的差异化产业政策。     

Limit order books and trade informativeness

In the microstructure literature, information asymmetry is an important determinant of market liquidity. The classic setting is that uninformed dedicated liquidity suppliers charge price concessions when incoming market orders are likely to be informationally motivated. In limit order book (LOB) markets, however, this relationship is less clear, as market participants can switch roles, and freely choose to immediately demand or patiently supply liquidity by submitting either market or limit orders. We study the importance of information asymmetry in LOBs based on a recent sample of 30 German Deutscher Aktienindex (DAX) stocks. We find that Hasbrouck's (1991) measure of trade informativeness Granger causes book liquidity, in particular that required to fill large market orders. Picking-off risk due to public news-induced volatility is more important for top-of-the book liquidity supply. In our multivariate analysis, we control for volatility, trading volume, trading intensity and order imbalance to isolate the effect of trade informativeness on book liquidity.     

后金融危机时期解读我国宏观经济政策

在国际金融危机持续蔓延时期,各国出台相应政策扭转不利局势。我国政府在2008年和2009年也出台了多项宏观政策来应对危机,并取得了一定的成效。危机已过,余波未平,在后金融危机时期,这些政策发挥着怎样的作用,今后宏观调控的方针和措施是什么?本文将针对这些问题一一解读。     

流动性在组合投资管理中的认识

在传统的均值-方差模型中,“市场流动性是充分的”假设使投资者忽略了流动性在组合投资管理中的重要性。流动性作为金融资产的三大属性之一,体现并作用于组合投资管理整个过程中。本文从流动性的内涵、流动性的股票交易特征、流动性与均值-方差模型的结合及行业流动性对组合投资的影响等角度探讨了流动性在组合投资管理中的作用,将组合投资的思维从二维空间拓展至三维空间,丰富了现代资产组合选择理论。

Does the liquidity effect guarantee a positive term premium?

This paper examines the liquidity effect and the term structure in two versions of the limited participation model—an imperfect information model and an adjustment cost model. With a discrete-state solution approach, I find a striking contrast: while the imperfect information model successfully generates the liquidity effect and the positive term premium seen in the data; the adjustment cost model replicates only the liquidity effect. This is because the adjustment cost that drives the liquidity effect in the adjustment cost model also creates an adjustment cost effect, which leads to a negative term premium.     

Heterogeneous Risk Preferences,Discount Rates and Land Contract Choice in Ethiopia

This paper analyses the role of risk and rate of time preference in the choice of land contracts. The analysis builds on the risk‐sharing and imperfect market explanations of contract choice. Unique data from Ethiopia, which contain land contract information and experimental risk and rate of time preference measures on matched landlord–tenant partners, are employed in the empirical analysis. The results show that landlord and tenant time preferences are significant determinants of contract choice. For landlords (but not tenants), risk preference is also significant, indicating the importance of financial constraints and production risk in the determination of contract choice. The results are of particular relevance to land market policy in Ethiopia, where production is risk‐prone, financial markets are imperfect, and where there is a major need for the development of vibrant land rental markets.     

Similarly traded securities: Greek common vs. preferred stock

This paper examines the price spread between voting (common) and non‐voting (preferred) stocks during the period 1990–95 for a sample of 55 Greek companies. Because in Greece preferred stocks are not essentially different from common stocks, a number of hypotheses were tested to explain the observed differences. The data reveal an average spread of 27.5% for the entire period which, however, varies across years considerably. In cross‐sectional regressions it was found that the volatility of common stock returns, the liquidity of common shares relative to preferred shares, the ownership concentration, and the minimum dividend yield guaranteed to preferred stockholders explain a significant portion of the spread.     

International tourism demand and the business cycle

The focus of this study is on presenting causes and hypotheses for the existence of asymmetric income and price effects on tourism demand across business cycles. The theoretical assumptions were tested by analyzing tourism import demand in different source markets, drawing on econometric models that provide for the magnitudes of price and income effects either to vary depending on the phase of the business cycle or to remain stable across the business cycles. The major outcome of this study is that the general assumption in most of the tourism demand studies—i.e. that the income effects are symmetric—should not be expected to be automatically true for every source market.
