We study the impact of the adoption of zero commissions by major retail brokers and find that retail brokers that started charging zero commissions dramatically increase their market share of client assets. In addition, these retail brokers increasingly routed orders off exchange (i.e., OTC) to...

We evaluate the role of foreign short-sale restrictions in muting the full return-response following negative earnings surprises for stocks cross-listed in unbanned markets. We update the global timeline of short-sale restrictions until the COVID-19 crisis period. Instead of regulatory price...
