Political uncertainty and a firm's credit risk: Evidence from the international CDS market

Journal of Financial Stability 2017 30, 53-66
Using a large sample of firms with single-name credit default swap (CDS) contracts in 30 countries, we document the evidence that political uncertainty, proxied by national election dummy, is positively related to firm-level credit risk. Specifically, this positive relation is more pronounced for the firms that have no political connection or poor international diversification, and in the countries with higher political uncertainty and lower investor protections. Further, by using a difference-in-differences approach, we find evidence to support idiosyncratic volatility and debt rollover channels through which political uncertainty affects the credit risk of individual firm.

Does privatization reform alleviate ownership discrimination? Evidence from the Split-share structure reform in China

Journal of Corporate Finance 2021 66, 101848
This paper investigates the institutional origins of ownership discrimination in bank lending through a staggered quasi-natural experiment: China's Split-share Structure Reform. State-Owned Enterprises (SOEs) have an advantage over non-SOEs in securing external financing to protect investment opportunities from cash flow fluctuations. This financing privilege declined significantly after the reform, which mandatorily converted SOEs' non-tradable state-owned shares into tradable shares, sharply increasing the likelihood of further privatization. Consistent evidence also exists in terms of bank lending behaviors. Further, we show both direct and indirect evidence that the effects were more pronounced among SOEs under higher threats of privatization (e.g., firms with larger increases in tradable shares, smaller workforce, and in industries peripheral to national strategy). The evidence suggests that banks proactively prefer SOEs for the perceived safety of loans under implicit government guarantee; when this privilege disappeared after the reform, banks reacted by allocating credits more fairly. This paper provides new evidence on the bright side of share structure reforms in mitigating credit misallocation and enlightens policy makers to practical resolutions to the financing inefficiency in emerging capital markets.

Political determinants of privatizations in China: A natural experiment based on politician career concerns

Journal of Corporate Finance 2024 87, 102620 open access
We study the political determinants of the world's largest privatization program by exploiting an age-related discontinuity of politician promotion in China. As a local politician's age exceeds 58, his promotion likelihood quickly diminishes. Consistent with changes in the politician's incentives, we find that Chinese cities whose top officials were older than age 58 were less likely to privatize local state-owned enterprises. Using the promotion discontinuity as an instrument, we report that privatization has significant effects on the firm's efficiency.

Investor Attention and Asset Pricing Anomalies

Review of Finance 2022 26(3), 563-593 open access
We investigate the relationship between investor attention and financial market anomalies. We find that anomaly returns tend to be higher following high-attention days. The result is robust after controlling for the effect of news and in a natural experiment setting in which a stock market regulation and rounding errors generate exogenous variations in attention. An analysis of order imbalances suggests that large traders trade on anomaly signals more aggressively upon observing higher attention. We discuss the extent to which the findings are driven by inattention-driven underreaction, bias amplification, or coordinated arbitrage mechanisms, thereby providing insight into the understanding of anomalies.

Withholding Bad News in the Face of Credit Default Swap Trading: Evidence from Stock Price Crash Risk

Journal of Financial and Quantitative Analysis 2024 59(2), 557-595 open access
Credit default swaps (CDSs) are a major financial innovation related to debt contracting. Because CDS markets facilitate bad news being incorporated into equity prices via cross-market information spillover, CDS availability may curb firms’ information hoarding. We find that CDS trading on a firm’s debt reduces the future stock price crash risk. This effect is stronger in active CDS markets, when the main lenders are CDS market dealers with securities trading subsidiaries, or when managers have more motivation to hoard information. Our findings suggest that debt market financial innovations curtail the negative equity market effects of firms withholding bad news.

Pledgeability and Asset Prices: Evidence from the Chinese Corporate Bond Markets

Journal of Finance 2023 78(5), 2563-2620 open access
We provide causal evidence on the value of asset pledgeability by exploiting a unique feature of Chinese corporate bond markets: bonds with identical fundamentals are traded on two segmented markets with different rules for repo transactions. Using a policy shock that rendered AA+ and AA bonds ineligible for repo on one market only, we compare how bond prices changed across markets and rating classes around this event. When the haircut increases from 0% to 100%, bond yields increase by 39 bps to 85 bps. These estimates help us infer the magnitude of the shadow cost of capital in China.
