房地产上市公司融资模式对投资行为的影响

借鉴 Aivazianetal 简化投资模型建立了融资模式对投资行为影响的理论模型,基于1998~2012年的面板数据,实证研究不同产权属性和不同规模房地产上市公司融资模式对投资行为的影响。研究发现：房地产上市公司的债务融资会促使投资增长,而股权融资会减少投资,内源性融资与投资行为的相关性并不显著;国有房地产上市公司的投资行为更加积极;大规模房地产上市公司受外部融资约束更强。为此,应完善房地产上市公司治理结构、拓宽融资渠道。     

中小投资者法律保护与公司权益资本成本

本文以1993年至2001年之间我国证券市场进行股权再融资的上市公司为样本,采用时间序列分析方法深入考察我国证券市场不同历史阶段里中小投资者法律保护与公司权益资本成本关系的变化。研究结果表明,在我国证券市场发展的历史实践中,随着中小投资者法律保护措施的加强,上市公司的权益资本成本出现一个逐步递减的过程现象;在控制公司特征和宏观经济变量的情况下,中小投资者法律保护程度与上市公司的权益资本成本呈显著的负相关关系。     

International spillovers of U.S. monetary uncertainty and equity market volatility to China’s stock markets

Due to the global economy that is currently being increasingly integrated and liberalized, the cross-country transmission of U.S. monetary policy surprises has become a critical issue attracting scholarly attention. This research thus extends the existing literature by assessing the causal linkages among U.S. monetary policy uncertainty (USMPU), equity market volatility, and China’s stock price index over the period from January 1994 to August 2021. We apply Granger causality in quantile analysis to explore the relationships in each quantile of the distribution in a comprehensible manner. The results indicate that equity market volatility and China’s stock price dynamics play little role in affecting USMPU. We also find that only greater changes in both positive monetary policy uncertainty and stock prices lead to changes in equity market volatility. Furthermore, fluctuations in monetary policy uncertainty and equity market volatility in the United States Granger-cause China’s stock prices. Knowing such causality results could prevent market participants from adopting a one-size-fits-all strategy.

Is a flat tax reform feasible in a grown-up democracy of Western Europe? A simulation study for Germany

The success of the flat rate income tax in eastern Europe suggests that this concept could also be a model for countries of western Europe. The present paper uses a simulation model to analyze the effects of revenue neutral flat rate tax reforms on equity and efficiency for the case of Germany. We find that a flat rate tax with a low tax rate and a low basic allowance yields positive static welfare effects amounting to approximately 1.8% of income tax revenue but increases income inequality. The increase in income inequality can be avoided by combining a higher tax rate with a higher basic allowance. But in this case, the efficiency gains vanish. We conclude that due to their limited efficiency effects and their problematic distributional impact, flat tax reforms are unlikely to spill over to the grown-up democracies of western Europe.      

A Bayesian framework for combining valuation estimates

Discounted cash flow, method of comparables, and fundamental analysis typically yield discrepant valuation estimates. Moreover, the valuation estimates typically disagree with market price. Can one form a superior valuation estimate by averaging over the individual estimates, including market price? This article suggests a Bayesian framework for combining two or more estimates into a superior valuation estimate. The framework justifies the common practice of averaging over several estimates to arrive at a final point estimate.     

不完全合同、退出的激励平衡和控制权转移

基于公平心理偏好的投资博弈——敲竹杠问题的一个行为解决

敲竹杠问题是不完全合约理论的中心话题,经典文献认为,如果合约是不完全的,当事人的专用性投资会引发敲竹杠风险从而导致无效率的专用性投资。但是,关于敲竹杠问题的文献通常假定事后谈判结果对事前投资成本不敏感。通过在雇佣双方的投资博弈中引入投资成本相关性这种合作的谈判方式,将传统敲竹杠模型中影响谈判力的因素与当事人对公平偏好的行为因素二者融合,本文证明:与传统的投资博弈相比,在投资成本影响企业(雇员)谈判力的情况下,双方有更强的专用性人力资本投资激励。雇佣双方所面临的敲竹杠风险取决于双方的初始谈判力,且双方有可能在事前做出社会最优甚至过度的投资。这也从一个方面解释了现实中大量存在的有效投资现象。
