Pyrolysis is a potential recovery method for waste printed circuit boards (WPCBs), but the organic brominated products are toxic and hazardous. Iron has been used as a catalyst for debromination from pyrolysis oil, but the effects of in-situ iron on WPCBs pyrolysis is still not well understood....

The supported noble metal catalysts have been demonstrated outstanding catalytic performance for the catalytic degradation of volatile organic compounds (VOCs), but their high cost, easy poisoning and sintering deactivation limit their further applications. Herein, we proposed a flexible and...

We investigate bank relationships in a rarely-considered context – consumer and small business credit cards. Using over one million accounts, we find during normal times, consumer relationship customers enjoy relatively favorable credit terms, consistent with the bright side of relationships,...

We investigate how relationship borrowers fare relative to others in loan contract terms (spread, collateral, maturity, amount) during times of need using the COVID-19 quasi-natural experiment. COVID-19 is superior for such analysis because it primarily affects borrowers rather than banks. Our...

We investigate bank relationships in a rarely considered context – consumer and small business credit cards. Using over one million accounts, we find during normal times, consumer relationship customers enjoy relatively favorable credit terms, consistent with the bright side of relationships,...

Using options-implied variance, a forward-looking measure of conditional variance, we revisit the debate on the idiosyncratic risk-return relation. In both cross-sectional (for individual stocks) and time-series (for the market index) regressions, we find a negative relation between...

This paper proposes an early-warning bank risk measure based on the syndicate concentration of recent syndicated loans that a bank participates in. At the bank level, higher values of the measure predict greater risks (i.e., loan loss provisions, idiosyncratic return volatility, default...

Using lenders becoming members of the Task Force on Climate-Related Financial Disclosures (TCFD) as a plausible exogeneous shock, we examine whether and how lenders' commitment to transparent climate-related disclosures affects borrower firms' environmental performance. We find that client firms...
