- I present a frequency-domain method for solving linear rational expectations models.
- I derive an analytical solution to new Keynesian models under the fiscal theory.
- The solution makes clear the cross-equation restrictions and policy transmission mechanisms.
- The method yields useful by-products which are not easily obtainable using time-domain methods.
This article illustrates a widely applicable frequency-domain methodology to solving multivariate linear rational expectations models. As an example, we solve a prototypical new Keynesian model under the assumption that primary surpluses evolve independently of government liabilities, a regime in which the fiscal theory of the price level is valid. The resulting analytical solution is useful in characterizing the cross-equation restrictions and illustrating the complex interaction between the fiscal theory and price rigidity. We also highlight some useful by-products of such method which are not easily obtainable for more sophisticated models using time-domain methods.
