What is the role of the bank in the diamond dybvig model?

Table of Contents

The banks in the model act as intermediaries between savers who prefer to deposit in liquid accounts and borrowers who prefer to take out long-maturity loans. Under ordinary circumstances, banks can provide a valuable service by channeling funds from many individual deposits into loans for borrowers.

Are bank Runs rational?

If enough depositors become concerned that a bank may experience more withdrawals than it’s prepared for, it becomes rational for depositors to try to get their money back rather than wait and risk getting nothing after the bank’s other depositors have withdrawn their money.

What is a bank run equilibrium?

runs.1 They show that the demand deposit contract can improve on a. competitive market, but it also has a “bad” equilibrium, a bank run, in. which depositors panic and withdraw their deposits immediately.

What is the Diamond-Dybvig model?

In theoretical terms, the Diamond–Dybvig model provides an example of an economic game with more than one Nash equilibrium. If depositors expect most other depositors to withdraw only when they have real expenditure needs, then it is rational for all depositors to withdraw only when they have real expenditure needs.

What is the Diamond–Dybvig model of bank runs?

How does the Diamond-Dybvig model explain the Nash equilibrium?

If enough depositors expect other depositors to withdraw their funds, then they all have an incentive to rush to be the first in line to withdraw their funds. In theoretical terms, the Diamond–Dybvig model provides an example of an economic game with more than one Nash equilibrium.
