Information risk and credit contagion

This paper demonstrates a positive relationship between information risk and the credit contagion effect. We use abnormal changes in the Credit Default Swaps (CDS) spreads to measure the contagion effect, and the dispersion of analyst forecasts as a proxy for information risk. We find that firms with higher information risk suffer a greater contagion effect that occurs in advance to the credit default events. This finding is robust under controls of key firm-specific characteristics and general condition of stock and credit markets.     

Risk assessment based on the analysis of the impact of contagion flow

This paper presents a new framework to model and calibrate the process of firm value evolution when an unanticipated exogenous event impacting one firm can contagiously affect other firms. The nature of propagation of such contagion is determined by the underlying connections between firms, which can adversely affect the tail risks of firm value, hence the securities issued by the firm. This paper combines the insights gained from the existing firm-value models and historical events into a structural model for flow of contagion among firms using a network-based approach. Rather than using stylized networks, we develop a data-driven approach for network construction where we define and calibrate several contagion variables to model the spread of contagion. This framework is applied for assessing firm-level risk under downside risk measures. Using actual data, our model illustrates how connections between firms can lead to heavy-tailed default distributions and default clustering observed in practice.     

Economic policy uncertainty and stock price crash risk

This paper studies the impact of economic policy uncertainty on stock price crash risk using data from China. We develop a new index to measure Chinese economic policy uncertainty and find that economic policy uncertainty has a remarkable positive effect on stock price crash risk. However, the effect reverses later. The results also indicate that the positive effect of economic policy uncertainty on stock price crash risk is more prominent for state‐owned enterprises. Moreover, this effect is more prominent for firms with higher information asymmetry and firms with greater disagreement among investors, indicating that economic policy uncertainty affects crash risk through two mechanisms: managers’ concealment of bad news and investors’ heterogeneous beliefs.     

The mechanism of credit risk contagion among internet P2P lending platforms based on a SEIR model with time-lag

The credit risk contagion of Internet peer-to-peer (P2P) lending platforms is an important part of Internet financial risk management and supervision. This study analyzes the contagion path of credit risk in Internet P2P lending. Based on complex network theory and the theory of infectious disease dynamics, the characteristics of Internet P2P lending development are combined to construct a SEIR model of credit risk transmission among Internet P2P lending platforms with time lag, and the robustness of the model is analyzed and proven. The influence of platform correlations, the susceptible immune rate, the platform elimination rate, contagion latency, the saturation coefficient, and the susceptibility input rate on credit risk contagion behavior among Internet P2P lending platforms is analyzed, using the equilibrium point and threshold value. The impact of each variable is analyzed by simulation. Corresponding countermeasures and suggestions are proposed to prevent and control credit risk contagion among these platforms.     

Entrepreneurial risk,investment, and innovation

I estimate the effect of uncertainty on risky innovation using a panel of 11,417 manufacturing firms. I find that an increase in uncertainty has a large negative effect on the risky innovation of entrepreneurial firms, while it does not have any significant impact on other firms. This negative effect is stronger for the less diversified entrepreneurial firms in the sample. The estimation results are consistent with the innovation dynamics generated in a model in which entrepreneurs are risk averse and cannot diversify the risk of their business.     

Labor unemployment risk and firm risk

This paper examines the effect of labor unemployment risk on firm risk. Using unemployment insurance benefits as a proxy for unemployment risk, we find an economically significant positive relation between unemployment risk and firm risk. This positive relation is more pronounced for firms that are more labor-intensive, have a higher layoff propensity and are more financially constrained. While existing literature that employs corporate policy measures such as debt and cash holdings suggests an opposite relationship, our paper presents evidence that the effects stemming from earnings management, earnings quality and reporting quality appear to dominate.

Expectations and systemic risk in EMU government bond spreads

This paper explores the determinants of 10-year sovereign bond spreads over the German Bund benchmark in the Euro Zone from 2000 to 2013, relying on cross-country quarterly data panel analysis. The paper focal point is the role of contagion and euro break-up risks in widening the sovereign bond yield differentials among EU member countries. Using a novel synthetic index capable of monitoring the sustainability of currency unions, the paper finds that market expectations of a euro’s break up and contagion from Greece were fundamental drivers of sovereign risk premia in peripheral countries.     

The impact of climate risk on earnings management: International evidence

This study explores the influence of climate risk on properties of firms’ financial reporting practices with observations collected from 64 countries between 2005 and 2016. We use a country-level climate risk indicator developed by Germanwatch to measure the degree of damage from extreme weather events, and find that climate risk positively influences firms’ engagements in both accruals-based and real earnings management. Furthermore, we document that the above-mentioned effects of climate risk are moderated by the quality of country-level public governance. Subsample analysis suggests that the main effect of climate risk on earnings management is more pronounced for firms from developed countries, for firms in environment-sensitive industries, and for firms reporting losses. Our findings, which are supported by a battery of robustness tests, have important implication for regulators and policymakers.     

Looking for risk premium and contagion in Asia-Pacific foreign exchange markets

This article tests pure contagion effects among four Asian foreign exchange markets, namely, Japan, Hong Kong, Singapore, and Taiwan during the 1997 Asian crisis. A conditional version of international capital asset pricing model (ICAPM) in the absence of purchasing power parity (PPP) is used to control for economic fundamentals or systematic risks. The empirical results show strong contagion effects in both conditional means and volatilities of those markets after systematic risks have been accounted for. Specifically, the contagion-in-mean effects are mainly driven by the past return shocks in Hong Kong, Singapore, and Taiwan. As for contagion in volatility, the lead/lag relationships appear to be multidirectional among Japan, Singapore, and Taiwan, but between Hong Kong and Singapore, and between Hong Kong and Taiwan, they are unidirectional, with Hong Kong playing the dominant role in generating negative volatility shocks. In addition, the conditional ICAPM with asymmetric multivariate general autoregressive conditional heteroscedastic in mean (MGARCH(1,1)-M) structure is able to explain/predict on average 17.28% of the return variations in those markets. Therefore, this study provide a further evidence that the time-varying risk premium is a very strong candidate in explaining the predictable excess return puzzle [Lewis, K. K. (1994). Puzzles in international financial markets. NBER Working Paper No. 4951] since the risk premia founded in this article are not only statistically significant but also economically significant.     

Growth options,macroeconomic conditions,and the cross section of credit risk

This paper develops a structural equilibrium model with intertemporal macroeconomic risk, incorporating the fact that firms are heterogeneous in their asset composition. Compared with firms that are mainly composed of invested assets, firms with growth options have higher costs of debt because they are more volatile and have a greater tendency to default during recession when marginal utility is high and recovery rates are low. Our model matches empirical facts regarding credit spreads, default probabilities, leverage ratios, equity premiums, and investment clustering. Importantly, it also makes predictions about the cross section of all these features.     

Intra‐industry bankruptcy contagion: Evidence from the pricing of industry recovery rates

How does bankruptcy contagion propagate among industry peers? We study the debt recovery channel of industry contagion by examining whether the cost of a company's debt is affected by the observed recovery rates of its bankrupt industry peers. Our results show that lower industry recovery rates are associated with higher loan spreads, but only when the contracts were originated during industry bankruptcy waves. Consistent with the debt recovery channel of industry contagion, we find that the negative effects of industry recovery rates are significantly stronger under situations where the effect is expected to be more salient.     

Corporate Governance,Political Connections,and Intra‐Industry Effects: Evidence from Corporate Scandals in China

This paper investigates intra‐industry spillover effects of corporate scandals in China. We demonstrate how a contagion effect spreads to peer firms depending upon the quality of corporate governance and their political connections. Good corporate governance in peer firms reduces the contagion effect of scandals. External governance has a stronger influence on reducing the contagion effect of both financial and non‐financial scandals, while ownership concentration and the quality of auditors play a more pronounced role in mitigating the contagion effect of financial scandals. State ownership helps to mitigate the negative influence of non‐financial scandals in individual‐owned firms, but not in state‐owned enterprises.     

Research on China's financial systemic risk contagion under jump and heavy-tailed risk

To accurately measure the dynamic characteristics of systemic risk contagion under the impact of extreme financial events, we construct a research framework that analyzes the contagion dynamics of systemic risk under extreme risk impact from the perspectives of both time and space. Based on the macro-jump CCA method, this paper extracts the heterogeneous volatility sequence of financial industries considering the thick tail of the distribution of financial assets returns. Then, the dynamic variation of systemic risk in the financial sectors is characterized from the time dimension. The volatility spillover network method is used to examine the spillover contagion of systemic risk among financial system sectors from the spatial dimension. Empirical studies have found that when considering the risk contagion level, the capital market service sector plays a risk‑leading role, followed by the currency service sector and the insurance sector. The measurement indicators that consider the jump risk and the tail risk have good early warning effects on extreme financial events. Seen from the spatial direction of risk spillover, the real estate sector exhibits the most obvious risk spillover effect on other sectors and can be regarded as the source of systemic risk, which suggests differentiated regulation.     

失信风险传染会影响债券定价吗？——基于担保网络大数据的实证研究

在债券定价研究中不仅应该考虑企业自身的信用风险,还应该考虑相关网络组织的传染风险。本文基于43万笔非金融企业间的担保数据,构建了企业信用担保网络,发现失信风险作为一种广义的信用风险,在担保网络中具有传染效应,该传染效应能够影响债券的信用利差。企业的失信行为产生了三类传染效应,一是直接传染效应,无论是发债主体的担保人出现失信行为,还是被担保人出现失信行为,都会引起发债主体的信用利差上升;二是局部感染效应,如果局部担保网络中失信主体的占比提升,可能引起投资者对发债主体的“团体处罚”,导致信用利差上升;三是全局扩散效应,失信信息沿担保网络向整个市场扩散,导致债券信用利差上升。从企业所有制来看,民营企业主要受微观的直接传染效应和中观的局部感染效应影响;而国有企业主要受全局扩散效应影响;被担保人的失信风险对两类企业都有显著影响。失信风险传染效应会降低企业的再融资能力,其中局部感染效应导致企业次年的借款融资额下降,全局扩散效应导致企业次年的债券融资额下降。     

Is recovery risk priced?

Recovery risk to explain corporate debt premia has not received much attention so far, most likely due to the difficulties around decomposing the expected loss. We exploit the fact that differently-ranking debt instruments of the same issuer face identical default risk but different default-conditional recovery rates. This allows us to isolate implied recovery under the T-forward measure without any of the rigid assumptions employed by prior studies. We find a pronounced systematic component in recovery rates for which investors should receive a premium. Comparisons to physical realizations show that the premium is quite time-stable and similar for different debt seniorities.     

Firm-level political risk and distance-to-default

This study provides the first empirical evidence of the relationship between firm-level political risk and distance-to-default. Based on our examination of a quarterly dataset of 2727 U.S. firms covering a period from January 2002 to April 2019, we conclude that firm-level political risk is negatively associated with distance-to-default. We document three economic mechanisms through which political risk increases default risk: information asymmetry, organizational capital, and investment growth. The evidence indicates that the association is more pronounced for firms with low analysts’ forecast accuracy, organizational capital, and investment growth. Employing hand-collected data, we also reveal that firms are able to exploit their corporate lobbying to immunize themselves against default risk. Our findings are robust to different endogeneity identifications, including a natural experiment, alternative distance-to-default proxies, and different sub-samples. Overall, we present novel evidence of an adverse impact of firm-level political risk on distance-to-default and how such a negative effect can be mitigated.     

New Zealand finance companies and risk premiums

This article uses the recent implosion of the finance company sector in New Zealand to examine a number of questions. In the period between the upsurge in the default rate in 2006 and the implementation of a Government Guarantee Scheme in October 2008, we find that the debt risk premiums within the deposit rates of these institutions were grossly inadequate to compensate for default risk, that depositors continued to make significant new deposits even into firms that failed shortly afterwards and that the failure of the companies to increase the risk premiums was likely out of concern that this would aggravate perceptions of default risk.     

Institutional cross-ownership and stock price crash risk

Using manually collected data of Chinese listed firms during the period 2007–2018, we provide strong and robust evidence that institutional cross-ownership is negatively associated with firm-specific stock price crash risk. Building on China’s institutional settings, we document that the negative relation is more pronounced for firms located in provinces with higher political uncertainty, or state-owned enterprises. This paper also conducts several mechanisms analyses and has confirmed three potential influencing mechanisms, such as information advantage, governance improvement and anticompetitive incentives, in explaining the effect of institutional cross-ownership on stock price crash risk. Overall, this paper develops a new perspective to investigate the ways to alleviate stock price crash risk in emerging markets.     

Non-banks contagion and the uneven mitigation of climate risk

This paper develops a framework for the short-term modelling of market risk and shock propagation in the investment funds sector, including bi-layer contagion effects through funds’ cross-holdings and overlapping exposures. Our work tackles chiefly climate risk, with a first-of-its-kind dual view of transition and physical climate risk exposures at the fund level. So far, while fund managers communicate more aggressively about their awareness of climate risk, it is still poorly assessed. Our analysis shows that the topology of the fund network matters and that both contagion channels are critical in its study. A stress test based on granular short-term transition shocks suggests that the differentiated integration of sustainability information by funds has made network amplification less likely, although first-round losses can be material. On the other hand, there is room for fund managers and regulators to consider physical risk better, and mitigate the second-round effects it induces, as these are less efficiently absorbed by investment funds. Improving transparency and setting relevant industry standards in this context would help mitigate short-term financial stability risks.
