Central bank balance sheet expansion is financed by commercial banks. It involves not just a substitution of liquid central bank reserves for other assets held by commercial banks, but also a counterpart alteration in commercial bank liabilities, such as in short-term deposits issued to finance...

The textbook optimal policy response to an increase in government debt is simple--monetary policy should actively target inflation, and fiscal policy should smooth taxes while ensuring debt sustainability. Such policy prescriptions presuppose an ability to commit. Without that ability, the...

We estimate a model in which fiscal and monetary policy behavior arise from the optimizing behavior of distinct policy authorities, with potentially different welfare functions. Optimal time-consistent policy behavior fits U.S. time series at least as well as rules-based behavior. American...
