Effects on the stock returns of insurance brokers and insurers are tested. The findings are: (1) GARCH effects are significant in modeling broker/insurer returns; (2) the suit generated negative effects on the brokerage industry and individual brokers, suggesting that contagion dominates competitive effects; (3) spillover effects from the brokerage sector to insurance business are significant and mostly negative, demonstrating industry integration; and (4) information-based contagion is supported, as opposed to the pure-panic contagion. © The Journal of Risk and Insurance, 2009.Market reaction to regulatory action in the insurance industry: The case of contingent commissionjournal articlehttps://api.elsevier.com/content/abstract/scopus_id/7795369730710.1111/j.1539-6975.2009.01327.x2-s2.0-77953697307WOS:000277328400004https://api.elsevier.com/content/abstract/scopus_id/77953697307
