Despite the increasing number of studies on monetary policy uncertainty, its role on the strategic interaction between fiscal and monetary policies has not been fully explored. Our paper aims to fill this gap by evaluating the consequences produced by multiplicative uncertainty in such a context.

Recent developments in macroeconomics resurrect the view that welfare costs of inflation arise because the latter acts as a tax on money balances. Empirical contributions show that wage re-negotiations take place while expiring contracts are still in place. Bringing these seemingly unrelated...

We explicitly model unions' concern for public expenditure, paving the way for an analysis of the potential gains from cooperation between the fiscal policymaker and the unions,...

Rational expectations are often used as a strong argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances...

This paper develops a simple New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model with rule-of-thumb consumers and external habits. Our theoretical model has a closed-form solution which allows the analytical derivation of its dynamical and stability properties. These properties are...
