# Douglas Diamond

> Douglas Diamond is an American economist and Merton H. Miller Distinguished Service Professor of Finance at the University of Chicago Booth School of Business. He was awarded the 2022 Nobel Prize in Economic Sciences, shared with Ben Bernanke and Philip Dybvig, for research on banks and financial crises. The Diamond-Dybvig model (1983) is one of the most influential papers in financial economics, providing the first rigorous theoretical explanation of why banks exist, why bank runs occur, and what policy responses can prevent them. The model shows that banks perform a valuable economic function by transforming illiquid long-term loans into liquid short-term deposits, but this very function makes them inherently vulnerable to self-fulfilling bank runs: if depositors believe others will withdraw, it becomes rational to withdraw first, leading to the collapse of an otherwise solvent institution. The model demonstrates that deposit insurance can eliminate this coordination failure by removing the incentive for preemptive runs. Diamond's subsequent work with Raghuram Rajan developed a theory of bank capital structure and fragility, showing why banks optimally use short-term debt despite the run risk it creates. His research on debt maturity structure, monitoring by financial intermediaries, and sovereign debt has been widely influential in banking regulation. Diamond has served as an editor of leading economics journals and as a consultant to the International Monetary Fund and the Federal Reserve.
