Banking, Liquidity, and Bank Runs in an Infinite Horizon Economy

We develop a variation of the macroeconomic model with banking in Gertler and Kiyotaki (2011) that allows for liquidity mismatch and bank runs as in Diamond and Dybvig (1983) . As in Gertler and Kiyotaki, because bank net worth fluctuates with aggregate production, the spread between the expected rates of return on bank assets and deposits fluctuates counter-cyclically. However, because bank assets are less liquid than deposits, bank runs are possible as in Diamond and Dybvig. Whether a bank
