金融科技对传统银行行为的影响——基于互联网理财的视角

本文使用2011-2015年263家银行的年报数据和北京大学数字金融研究中心基于蚂蚁金服用户数据构建的地市级数字金融普惠指数,探究金融科技的发展对银行行为的影响。研究发现金融科技的发展实质上推动了一种变相的利率市场化,改变了银行的负债端结构,使得银行负债端越来越依赖于同业拆借等批发性资金。负债端结构的改变导致银行资产端风险承担偏好上升,但是借贷利率和净息差都有所下降。即银行选择了更高风险的资产来弥补负债端成本上升所造成的损失,但并没有将成本向下游企业转移。此外,本文还发现规模越大的银行受到金融科技的冲击越小。     

A comparative study of eight COVID-19 protective measures and their impact on Swiss tourists’ travel intentions

A comparative vignette-based experimental survey design incorporating various socio-psychological factors, linked to the Theory of Planned Behavior (TPB), the Health Belief Model (HBM) and the Domain-Specific Risk-Taking scale (DOSPERT) was carried out to test variations in eight travel-related COVID-19 protective measures on Swiss tourists’ travel intentions. Among the tested measures, vaccination passports, surgical masks and quarantining are those that stand out the most, with surgical masks having the greatest acceptance and willingness to adopt while traveling. Quarantining, on the other hand, appears to have a deterrent influence on travel intentions, and vaccination passports have the lowest perceived barriers during travel, but the highest perceived benefits in mitigating the spread of the infection. The discussion of individual differences has specific implications for tourism management against the background of our empirical findings.     

Financial statement comparability and bank risk-taking

This study examines the relationship between financial statement comparability and bank risk-taking. Our analysis of a sample of publicly listed U.S. banks over the 1994–2019 period shows that banks with more comparable financial statements are related to significantly less risk-taking. We also find that the negative relationship between comparability and risk-taking is more pronounced for firms with more severe moral hazard and agency problems. Our documented findings are robust across alternative measures of comparability and risk-taking and considering change analysis, after controlling for strength of corporate governance and using propensity score matching and two-stage least squares estimation to address endogeneity concerns. Our analysis also shows that the relationship between financial statement comparability and bank risk-taking is stronger for smaller banks than for larger banks. Overall, this study provides unique insights into the role of financial statement comparability in curbing risk-taking in the banking sector.     

The effect of risk-taking behavior on profitability: Evidence from futures market

We explore how futures traders make a tradeoff between risk and return by examining their risk-taking in the action. By applying a novel measure to their trade-by-trade transactions to capture their tendency in risk-taking, we find a general tendency to reduce risk-taking by cutting positions when facing losses or gains, and the tendency is stronger in the case of losses. However, great variations exist among traders in the risk-taking tendency and the results for trading are opposite for profitable and unprofitable traders. For the unprofitable, more risk-taking by trading more actively leads to greater losses. This is concrete evidence for the prevailing belief in the literature that trading too much, arguably due to overconfidence, is hazardous to investor's wealth. Contrary to that belief, however, we find fresh evidence that more active trading by the profitable traders leads to greater profits, suggesting their trades are likely based on ability and skills.     

The role of institutional investors in propagating the 2007 financial crisis in Southern Europe

The 2007 financial crisis has affected Southern European companies (Spanish, Portuguese, Italian and Greek) more than others. From a Minskyan bubble-burst cycle perspective (Minsky, 1986), we study the relation between institutional ownership structure and corporate risk-taking for a sample of non-financial listed companies from Spain, Portugal, Italy and Greece for the period 2001–2014. Our results suggest that the financial deregulation process, that lead to the financialization of the world economy before the 2007 financial crisis and the favourable macroeconomic scenario encouraged corporate risk-taking in those countries. We also find that the lack of effective control mechanisms provided an incentive for investment funds to assume a proactive role, encouraging companies to overinvest in risky projects.     

Debt enforcement,investment, and risk taking across countries

We argue that the prospect of an imperfect enforcement of debt contracts in default reduces shareholder–debtholder conflicts and induces leveraged firms to invest more and take on less risk as they approach financial distress. To test these predictions, we use a large panel of firms in 41 countries with heterogeneous debt enforcement characteristics. Consistent with our model, we find that the relation between debt enforcement and firms’ investment and risk depends on the firm-specific probability of default. A differences-in-differences analysis of firms’ investment and risk taking in response to bankruptcy reforms that make debt more renegotiable confirms the cross-country evidence.     

Risk-taking behavior of technology firms: The role of performance feedback in the video game industry

This study focuses on what drives technology-driven companies to engage in risk-taking behavior by serving new markets. Building on the behavioral theory of the firm and prospect theory, this study suggests that technology-driven organizations tend to respond to past performance rather than future possibilities. Using a sample of 5312 video games from 362 game developers, the results reveal that market performance trend and market performance variability have opposing effects on risk-taking behavior: while a positive market performance trend negatively influences a company's tendency to venture into new markets, a high-degree of market performance variability tends to positively influence new market entry. The study also finds opposite results for expert performance trend and expert performance variability: companies with consistently positive expert evaluations are more likely to enter into new markets, while variability in expert evaluations has a negative effect on new market entry. Furthermore, the effects of expert performance trend and variability are conditional on market performance trends. Finally, the results suggest that companies that venture into new markets tend to choose relatively similar markets if these companies are suffering from a negative market performance trend or a negative expert review trend.     

货币政策和银行风险承担：一种非线性关系

宽松的货币政策会通过估值、收入和现金流机制,追逐收益机制以及中央银行沟通和反应机制等渠道增加银行风险承担,通过风险转移机制降低银行风险承担,从而导致货币政策与银行风险承担之间可能存在复杂的非线性关系。本文使用面板阈值模型,基于我国银行业数据研究了货币政策对银行风险承担的影响,发现我国货币政策对银行风险承担的影响存在门限效应,即货币政策对银行风险承担的影响取决于货币政策基准利率偏离泰勒规则利率的程度。当这种偏离小于门限值时,宽松货币政策会增加银行风险承担;当这种偏离大于门限值时,宽松货币政策会降低银行风险承担。本文研究对更好地理解我国货币政策对银行风险承担及金融稳定的影响有一定参考意义。     

基金业绩排名与基金经理的冒险行为

本文利用2005-2010年间开放式股票型和混合型基金的数据,研究年度基金业绩排名对基金经理冒险行为的影响。与相对业绩排名激励机制会导致基金经理过度冒险的假设相一致,本文发现,年中业绩排名靠后的基金经理(输家)在下半年提高所持有资产组合的风险的程度要大于年中业绩排名靠前的基金经理(赢家)。进一步研究发现,基金经理提高下半年所持有资产组合的风险并不能显著提高下半年基金的业绩。特别是在熊市中,提高下半年所持有资产组合的风险反而显著降低了基金下半年的业绩。     

货币政策、银行资本与风险承担

考虑存款准备金率作为我国货币政策的重要工具,本文在D-L-M模型中引入了法定存款准备金,分析了货币政策对银行风险承担的影响,发现货币政策对银行风险承担的影响取决于银行资本状况。接着利用我国14家上市银行的季度数据,采用门限面板回归模型实证分析了货币政策对银行风险承担的影响。实证结果表明紧缩的货币政策对银行风险承担
