3 US economists win Nobel for research on banks, financial crises
Stockholm: The 2022 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel was awarded to Ben S Bernanke, Douglas W Diamond and Philip H Dybvig "for research on banks and financial crises" at the Royal Swedish Academy of Sciences in Stockholm on Monday. This year's Nobel prize laureates in economic sciences significantly improved our understanding of the role of banks in the economy, particularly during financial crises, as well as how to regulate financial markets, read a statement issued by the academy.
Diamond and Dybvig developed theoretical models that explain why banks exist, how their role in society makes them vulnerable to rumours about their impending collapse and how society can lessen this vulnerability.
The duo presented a solution to bank vulnerability, in the form of deposit insurance from the government. When depositors know that the state has guaranteed their money, they no longer need to rush to the bank as soon as rumours start about a bank run.
Diamond also showed how banks perform a societally important function. As intermediaries between savers and borrowers, banks are better suited to assessing borrowers' creditworthiness and ensuring that loans are used for good investments. Former Federal Reserve chairman Ben Bernanke, meanwhile, analysed the Great Depression of the 1930s, the worst economic crisis in modern history. Among other things, he showed how bank runs were a decisive factor in the crisis becoming so deep and prolonged.
Using historical sources and statistical methods, Bernanke's analysis showed which factors were important in the drop in gross domestic product. He found factors that were directly linked to failing banks accounted for the lion's share of the downturn.
The work done by the trio has been crucial to subsequent research that has enhanced our understanding of banks, bank regulation, banking crises and how financial crises should be managed, read the statement. The academy added that the trio's research reduces the risk of financial crises developing into long-term depressions with severe consequences for society.
