Securities Arbitrator Bias

[A]rbitrators who also represent brokerage firms or brokers in other arbitrations award significantly less compensation to investor-claimants than other arbitrators. This relation between representing brokerage firms and arbitration awards remains significant even when we control for political outlook. We find no significant effect for attorney-arbitrators who represent investors or both investors and brokerage firms. We report that ideology also correlates significantly with arbitration awards - arbitrators who donate money to Democratic political candidates award greater compensation than arbitrators who donate to Republican candidates.

From here.
