We show that divestitures accompanying horizontal mergers affect both the market power potential and the competitive efficiency of merging firms. Stock price reactions of customer firms are more positive (hence divestitures are more effective in mitigating the market power impact of the merger)...

Cobalt-based catalysts have been widely explored in the degradation of organic pollutants based on peroxymonosulfate (PMS) activation. Herein, we report an MXene nano-Co3O4 co-catalyst enriched with oxygen vacancies (Ov) and steadily fixed in nickel foam (NF) plates, which is used as an...
