Yes, there is a good basis for concern that executive pay arrangements have contributed to excessive risk-taking during the run-up to the financial crisis. To be sure, other factors were clearly at work: the environment within which firms operated grew riskier due to asset bubbles generated by macro policies and global factors, and regulatory constraints on risk-taking and capital requirements were too lax. As financial economists generally recognize, however, for any given environment and outside constraints, the performance and risk choices of firms depend substantially on the incentives of firms’ executives. Unfortunately, rather than provide incentives to avoid excessive risk-taking, the design of pay arrangements in financial firms encouraged such risk-taking.

Of course, despite incentives to take excessive risks, some executives might have avoided doing so due to professional integrity, reputational concerns, or fiduciary duty norms. And some executives taking excessive risks might have done so due to their under-estimation of the risks taken. But economics and finance teach us that incentives often matter. Thus, to the extent that pay arrangements provided significant incentives to take excessive risks, the possibility that such incentives in fact contributed materially to the excessive risks taken in the run-up to the crisis should be seriously considered.

In fact, pay arrangements did provide substantial incentives for excessive risk-taking. Under the standard design of pay arrangements, executives were fully exposed to the upside of risks taken but enjoyed substantial insulation from part of the downside of such risks. As a result, executives had incentives to increase risk-taking beyond optimal levels.
