In contrast to previous literature, we show that it is possible to use interest rate rules in standard monetary models to implement equilibria that are globally unique. This is a contribution to a literature that either concentrates on conditions for local determinacy, or criticizes that...

We determine the second best rule for the inflation tax in monetary general equilibrium models where money is dominated in rate of return. The results in the literature are ambiguous and inconsistent across different monetary environments. We derive and compare the optimal inflation tax...
