We develop a canonical framework to think about credit market frictions and aggregate economic activity in the context of the current crisis. We use the framework to address two issues in particular: first, how disruptions in financial intermediation can induce a crisis that affects real...

We develop a variation of the macroeconomic model of 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...

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...

We develop a variation of the macroeconomic model of banking in Gertler and Kiyotaki (2011) that allows for household liquidity risks and bank runs as in Diamond and Dybvig (1983). As in Gertler and Kiyotaki, because bank net worth fluctuates with aggregate production, the spread in the expected...

This paper is a theoretical study into how credit constraints intereact with aggregate economic activity over the business cycle. We construct a model of a dynamic economy in which lenders cannot force borrowers to repay their debts unless the debts are secured. In such an economy, durable...
