Previous studies rarely discuss the effect of margin trading on future stock price crash risk, though margin trading is often blamed for destabilizing stock market. We propose three possible mechanisms through which margin trading may affect crash risk. Our empirical results show that neither...

This paper proposes Spillover Persistence as a measure for financial fragility. The volatility paradox predicts that fragility builds up when volatility is low, which challenges existing measures. Spillover Persistence tackles this challenge by exploring a novel dimension of systemic risk: loss...

We employ extreme value theory to identify stock price crashes, featuring low-probability events that produce large, firm-specific negative outliers in the conditional distribution. Traditional methods employ approximations under Gaussian assumptions and central moments. This is inherently...

This paper innovatively establishes the interrelationship between type I agency costs (conflicts between managers and shareholders) and type II agency costs (conflicts between controlling and minority shareholders). We further analyze the impact of agency cost interactions on the volatility of...
