We study optimal fiscal and monetary policy in an environment where explicit frictions give rise to valued money, making money essential in the sense that it expands the set of feasible trades. Our main results are in stark contrast to the prescriptions of earlier flexible-price Ramsey models....

I study how the general and specific details of a micro founded monetary framework affect the determination of policy when the government has limited commitment. The conduct of policy depends on the interaction between the incentive to smooth distortions intertemporally and a time-consistency...

The Global Integrated Monetary and Fiscal model (GIMF) is a multi-region, forward-looking, DSGE model developed by the Economic Modeling Division of the IMF for policy analysis and international economic research. Using a 5-region version of the GIMF, this paper illustrates the model's...
