How frequently are the payoff and the purchase-and-assumption methods used by the FDIC? Using FRED, plot the total number of institutions receiving such assistance (FRED codes: BKTTPIA641N for purchase and assumption; and BKTTPOA641N for the payoff method). On the same graph, plot as a second line the purchase and assumption data separately (so that you graph will show one line with the total and a second line with the purchase and assumption data only). Describe the evolution over the long run. From what you know about the total number of depository institutions, does the total number of resolutions seem high or low?
