Bank stress testing, human capital investment and risk management

Journal of Financial Economics 2025 171, 104104
This paper studies banks’ investment in risk management human capital following the Global Financial Crisis and the advent of stress testing. Our results suggest that ‘Too Big to Fail’ distortions may have weakened large banks’ incentive to invest in risk management talent. Stress testing, which focuses on the largest banks, spurred demand for skilled quantitative risk managers, but only narrowly in anticipation of a test and following poor performance on a test. Stress testing does not affect demand for the over 90 % of risk management jobs not linked to passing tests, limiting its effectiveness in improving risk management practices.

Optimal delegation contract with portfolio risk

Journal of Banking & Finance 2025 171, 107357 open access
Conventional linear benchmarked contracts tend to cause excessive pegging to the benchmark and thus price distortion of stocks in the benchmark. This paper studies the optimal delegation contract when there is principal-agent friction. Specifically, it explores the impacts of incorporating the risk of invested portfolio in the contract on optimal strategies of the principal and the agent as well as on equilibrium asset prices. When agency friction is severe, the optimal contract provides rewards for portfolio risk to improve risk sharing and grants compensation for index return to propel the agent to deviate from pegging to index. In equilibrium, the principal conducts index investment while the agent invests only in individual risky assets, and price distortion caused by agency friction is mitigated.
