In this study, we examine the impact of high-frequency trading (HFT) on stock price crash risk in 24 countries over the period 1990 to 2019. Using a difference-in-differences approach, we find that HFT participation significantly increases stock price crash risk. We attribute this finding to the...

We show that limited dealer participation in the market, coupled with an informational friction resulting from high frequency trading, can induce demand for liquidity to be upward sloping and strategic complementarities in traders' liquidity consumption decisions: traders demand more liquidity...

Thus, the parsimonious formula is not based on fundamental valuation. For...

In this paper, we investigate short sale constraints' impact on the incidence of extreme stock market movements. The latter can be used to proxy for the likelihood of tail events like crashes and bubbles in a market and, thus, is a crucial measure of stock market stability. Since crashes and...

This paper attempts to investigate the impact of credit information sharing on bank-specific stock price crash risk. Using a sample of 1,402 listed-banks in 55 countries for the period 2005-2013, we show that credit information sharing through public credit registries is negatively associated...

Stock markets play a key role in corporate financing in Asia. However, despite their increasing importance in terms of size and cross-border investment activity, the region's markets are reputed to be more “idiosyncratic” and less reliant on economic and corporate fundamentals in their...

In 2009, the promise of a comprehensive federal cap and trade bill to address climate change fell apart. At least in part, this was due to the fears that exotic 'carbon' financial instruments might cause more financial crises. As California launches it economy wide carbon trading system, and...

In an attempt to understand the impact of derivative market reforms, this paper focuses on the spreads of centrally cleared CDSs using a unique data set of voluntarily cleared non-financial single-name contracts over the period from January 2009 to June 2013. Controlling for a number of factors...
