Douglas W. Diamond, Merton H. Miller Distinguished Service Professor of Finance, is considered a founder of modern banking theory. In 2022 he received the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel (together with Ben Bernanke and Philip H. Dybvig) for his scholarship on the role of banks in the economy, particularly in times of crisis.
The Diamond-Dybvig Model, coauthored with Dybvig in 1983, explains the important role of financial intermediaries like banks in creating liquidity for investors and the attendant risk of bank runs if investors lose faith in these institutions’ ability to provide liquid assets. The model has been powerfully influential, informing government and central banking policy and gaining particular importance during the 2008 financial crisis.
Diamond’s papers on lending are similarly foundational. “Financial Intermediation and Delegated Monitoring,” for example, analyzes the role of banks in assessing the risk of lending to borrowers and monitoring their repayment—and why this work is more effectively performed by institutions than individuals.
Diamond is a member of the American Academy of Arts and Sciences and the National Academy of Sciences. He has been at the University of Chicago since 1979.
