A study of dispute resolution at Fortune 1,000 corporations shows many are using binding arbitration — adjudication with private judges — less and relying more on mediated negotiation and other more informal, quick and inexpensive methods.

The study, based on a 2011 survey of corporate counsel developed by researchers at Cornell and Pepperdine universities, with input from the International Institute for Conflict Prevention & Resolution, indicates that although the approaches of large corporations vary, decisions about how to manage conflict usually boil down to issues of control.
