Corporate Stock and Bond Return Correlations and Dynamic Adjustments of Capital Structure

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case.

Foreign Direct Investment in the Enlarged EU: Do Taxes Matter and to What Extent?

Foreign direct investment is of increasing importance in the European Union. This paper estimates the effect of taxes on foreign direct investment (FDI) flows and on three sub-components of these flows for the countries of the enlarged European Union. The model in the spirit of gravity equations robustly explains FDI flows between the 25 member states. Sample selection needs to be addressed in the estimation. We show that the different subcomponents of FDI should and indeed do react differently to taxes. After controlling for unobserved country characteristics and common time effects, the top statutory corporate tax rate of both, source and host country, turn insignificant for total FDI and investment into equity. However, high source country taxes clearly increase the probability of firms to re-invest profits abroad and lower the percentage of debt financed FDI. This might reflect profit re-allocation to avoid taxes. Market size factors have the expected signs.

数字偏好与股票收益异常——来自上海证券交易所的经验证据

本文研究股票代码对股票收益的影响。研究发现,由于数字偏好效应的存在,投资者刻意回避代码以“4”结尾的股票。在较长时间内,尾数是“4”的股票收益低于给定风险水平下的市场必要收益。但这一现象受到股市行情的影响,牛市行情时,投资者回避“4”的行为表现明显,而熊市行情时则会趋向消失。具体表现为：牛市行情下,“4”组合的资产收益小于给定风险水平下的市场必要收益,熊市行情则无此现象。本文从行为金融莹晶当磨时杖一仑蜃由市扬耳夔讲符T觎崧     

外国直接投资对山东半岛环境影响

文章采用熵值赋权法计算山东半岛2000-2008年度环境污染的评价指标值,采用联立方程计量经济学模型,就外国直接投资和环境污染之间的关系进行实证检验。研究结果表明,外国直接投资通过规模效应加剧山东半岛的环境污染,但其结构效应对环境产生正面影响,技术效应没有产生具有显著统计意义的影响。应该通过法律手段、行政手段与市场手段改善FDI对环境的消极影响。
