东道国金融发展对中国企业对外直接投资的影响:二元边际与生产率门槛

文章基于中国上市企业2008-2015年对外直接投资数据，分析东道国金融发展在扩展边际和集约边际上对企业对外直接投资决策以及投资所需生产率水平的影响。研究发现，在不同生产率的企业中东道国金融发展的影响是异质性的。较高的金融发展水平会系统性地降低投资所需的生产率水平，进而促进中国企业对外直接投资的概率、次数和规模。进一步的研究还发现，在经济发展水平比中国高的东道国金融发展的生产率效应更显著，投资所需生产率下降得更多。尽管如此，高经济发展水平东道国的最低生产率门槛仍然高于低经济发展水平的东道国。控制了金融发展指标和企业全要素生产率的内生性后，结果依然稳健。     

Discovering bank risk factors from financial statements based on a new semi‐supervised text mining algorithm

This paper aims to comprehensively uncover bank risk factors from qualitative textual risk disclosures reported in financial statements, which contain a huge amount of information on bank risks. We propose a new semi‐supervised text mining approach named naive collision algorithm to analyse the textual risk disclosures, which can more accurately identify bank risk factors compared with the typical unsupervised text mining approach. We identified 21 bank risk factors in total, which is far more than identified in previous studies. We further analyse the importance of each bank risk factor and how the importance of each risk factor changes over time.     

Did the value premium survive the subprime credit crisis?

We provide evidence that value stocks significantly underperformed growth stocks during the subprime credit crisis, despite a positive value premium before the crisis. The reversal in the value premium concentrates in financially constrained firms, suggesting it was due to the adverse influence of the crisis rather than confounding effects. These findings are robust to alternative financial constraint proxies and asset pricing models. The observation that value stocks are vulnerable to losses during extreme downturns like the crisis is consistent with them being riskier than growth stocks. Our findings have implications for the academic debate on the underlying cause of the value premium and for investors on the profitability of value investing strategies.     

Floating a “lifeboat”: The Banque de France and the crisis of 1889

When faced with a run on a “systemically important” but insolvent bank in 1889, the Banque de France pre-emptively organized a lifeboat to ensure that depositors were protected and an orderly liquidation could proceed. To protect the Banque from losses on its lifeboat loan, a guarantee syndicate was formed penalizing those who had participated in the copper speculation that had caused the crisis bringing the bank down. Creation of the syndicate and other actions were consistent with mitigating the moral hazard from such an intervention. This episode contrasts the advice given by Bagehot to the Bank of England to counter a panic by lending freely at a high rate on good collateral, allowing insolvent institutions to fail.     

Financial development,financial liberalization and social capital

The relationship between financial liberalization policies and financial development is controversial. The impact of these policies differs greatly across countries. In the literature, the quality of formal institutions has been identified as an important source of this heterogeneity, as countries with a weak institutional environment generally fail to benefit from financial liberalization. Using panel data covering 82 countries for the period 1973–2008, we find evidence that social capital may substitute for formal institutions as a prerequisite for effective financial liberalization policies. In particular, we find that during the post Washington-consensus period countries with a high prevailing level of social capital can ensure that financial liberalization positively influences financial development, despite the poor quality of their formal institutions.     

Hedging house price risk with futures contracts after the bubble burst

This paper extends the existing literature on managing house price risk. While previous work finds that a hedger would have reduced a large amount of variance in housing returns in Las Vegas, Nevada using Chicago Mercantile Exchange (CME) futures contracts, we show that neither static nor dynamic strategies would have maintained an effective hedge during the significant decline in housing prices. The inability to hedge house price risk using CME futures contracts ultimately calls into question the long-term viability of housing futures.     

How does corporate social responsibility affect financial performance,financial stability,and financial inclusion in the banking sector? Evidence from Pakistan

This paper examines the impact of corporate social responsibility (CSR) on the financial performance, financial inclusion, and financial stability of the banking sector, focusing on annual data for 20 Pakistani commercial banks for the period 2008–2017. The results suggest that CSR, as well as age and size, has a positive impact on all three factors. However, high levels of leverage reduce financial inclusion and financial stability, while financial inclusion is also negatively associated with the tangibility of assets.     

数字经济对中国全要素生产率的影响机理:提升效应还是抑制效果？

数字经济是新时代引领中国经济高质量发展的关键抓手。然而现阶段数字经济普惠性发展尚未实现，掣肘着其对国内全要素生产率的提升力度。文章在理论分析的基础上，基于熵权TOPSIS法测算了2012-2018年中国数字经济发展水平指数，探讨了中国数字经济对全要素生产率的影响机理。研究发现：数字经济的发展显著提升了中国全要素生产率水平，但区域层面上，东部地区的数字经济发展明显领先于中西部地区，引领着中国全要素生产率快速增长。从全要素生产率的分解指标来看，数字经济推动了技术效率提升，但现阶段国内关键核心技术环节薄弱以及数字产业化带来的人才和资金的虹吸效应导致数字经济对技术进步产生了阻碍作用。此外，当前数字经济对不同产业的渗透度存在明显的不均衡性，筑高了创新资源的流动壁垒，影响产业间协调创新及合理化布局，进而抑制了对全要素生产率的提升力度。进一步的机制检验表明在创新环境的支持下，人才集聚及金融规模强化了数字经济对全要素生产率的提升力度。     

Do leveraged warrants prompt individuals to speculate on stock price reversals?

Using proprietary data on bank-issued knock-out warrants written on a stock index, we find that individual investors’ aggregate warrant portfolio speculates against the short-term trend of the index. We argue that contrarian trading is driven by the interaction of product design and investors’ preference for large leveraged positions. Investors tend to open larger positions whenever warrants offer higher leverage. As a result, investors open an aggregate long position when calls offer higher leverage than puts. Since knock-out leverages move systematically with the underlying, aggregate warrant positions become contrarian even if investors do not intend to speculate on reversals.     

金融资源配置、技术进步与经济高质量发展

随着我国发展阶段及内外部条件的变化,科技创新已成为新时代引领我国经济高质量发展的核心驱动力。本文以金融驱动技术进步的视角,构建内生增长DSGE模型,分析金融资源配置、技术进步和经济增长之间的关系。研究佐证了我国技术创新的逆周期性,并发现金融资源在企业生产性投资与创新投资之间的分配,可以通过改变生产要素投入规模和技术进步率两种途径影响经济增长,且这两种影响之间存在“跷跷板”关系,但后者更具主导性。在此基础上,诠释了金融、技术与经济的动态传导机制:经济扩张期,企业生产规模扩张,金融资源对生产性投资的支持增加,对创新的投入相对减少,技术进步率放缓;经济收缩期,企业缩减生产规模,金融资源对生产性投资的支持减少,对创新的投入相对增加,技术进步率提升。本研究的政策启示为,面对当前发展新矛盾、新挑战,应把握发展新格局、新机遇,进一步深化金融改革,优化金融资源配置机制,鼓励创新投资,充分发挥股权市场对企业研发创新的支持作用,并辅以稳健适度的宏观调控政策,为企业创新提供良性的宏观环境,激活企业创新需求,促进技术进步,推动经济高质量发展。
