Question 2. Bank Run. Consider the Diamond-Dybvig model we discussed in class. Suppose marginal utility of consuming c is given by c-². Gross interest rate is R = 1.5. Time preference is ẞ = 0.9. Probability of becoming first type is λ = 0.2. a) What is the efficient consumption level of type 1 (c)) and type 2 ( c). You need to solve for optimality condition and resource constraint. Answer must be numeric. b) Explain why 1 < c^, and c½ < R is better than c₁ = 1 and C2 = R. c) Now consider the contract we discussed in class that the bank offers. Suppose r₁ = 1. Explain why there wouldn't be a bank run in this situation. Why this is not a desirable contract?
