Climate Risk Exposure and Firm Default Risk: OECD Insights into the Moderating Role of Innovation

open access: yesAsia-Pacific Journal of Financial Studies, EarlyView.
Abstract By analyzing 19 715 firm–year observations from 2640 companies across 38 OECD member economies between 2002 and 2023, this study examines the effect of climate risk exposure on firm default risk. Our findings suggest that firms with higher climate risk exposure, as measured by physical risk and transition risk indicators, are more likely to ...

Skew Premiums Around Earnings Announcements

open access: yesFinancial Review, EarlyView.
ABSTRACT We examine skew premiums in equity options around earnings announcements. We use the realized returns to delta‐neutral risk reversal option spreads as a proxy for the skew premiums. We find skew premiums are economically significant around earnings announcements and are not explained by changes in variance risk premiums.

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.
