Standard solution methods for linearised models with rational expectations take the structural parameters to be constant. These solutions are fundamental for likelihood based estimation of such models. Regime changes, such as those associated with either changed rules for economic policy,...

Standard solution methods for linearised models with rational expectations take the structural parameters to be constant. These solutions are fundamental for likelihood-based estimation of such models. Regime changes, such as those as- sociated with either changed rules for economic policy,...

Standard solution methods for linear stochastic models with rational expectations presuppose a time-invariant structure. Consequently, credible announcements that entail future changes of the structure cannot be handled by standard solution methods. This paper develops the solution for linear...

This paper studies determinants of some aspects of the structure of cities, including density and the price of land and housing. We use a version of the Alonso-Muth-Mills model, calibrated to broadly match some of the features of a representative large city. While the calibrated model omits many...

In a model where the risk premium on long-term debt is, in part, endogenously determined, we study two kinds of unconventional monetary policy: long-term nominal interest rates as operating instruments of monetary policy and announcements about the future path of the short-term rate. We find...

Structural change has been conjectured to lead to an upward bias in the estimated forward expectations coefficient in New-Keynesian Phillips curves. We present a simple New-Keynesian model that enables us to assess this proposition. In particular, we investigate the issue of upward bias in the...
