We combine an estimated monetary policy rule featuring time-varying trend inflation and stochastic coefficients with a medium scale New Keynesian framework calibrated on the U.S. economy. We find the impact of variations in trend inflation on the likelihood of equilibrium determinacy to be both...

In a simple New Keynesian model, we derive a closed form solution for the inflation persistence parameter as a function of the policy weights in the central bank’s Taylor rule. By estimating the time-varying weights that the FED attaches to inflation and the output gap, we show that the...

This work is a PhD dissertation, written at the Department of Economics, McGill University. The thesis offers a new framework for inflation as a process of restructuring. Contrary to existing theories of inflation, which tend to take structure and institutions as given for the purpose of...

This paper aims to improve the understanding of U.S. inflation dynamics by separating out structural from cyclical effects using frequency domain techniques. Most empirical studies of inflation dynamics do not distinguish between secular and cyclical movements, and we show that such a...

We investigate how the dynamic effects of oil supply shocks on the US economy have changed over time. We first document a remarkable structural change in the oil market itself, i.e. a considerably steeper, hence, less elastic oil demand curve since the mid-eighties. Accordingly, a typical oil...

In this paper we formulate a baseline disequilibrium AS-AD model and empirically estimate it with time series data for the U.S.-economy. The version of the model used here exhibits a Phillips-curve, a dynamic IS curve and a Taylor interest rate rule. It is based on sticky wages and prices,...

I estimate a medium-scale New-Keynesian model and relax the conventional assumption that the central bank adopted an active monetary policy by pursuing inflation and output stability over the entire post-war period. Even after accounting for a rich structure, I find that monetary policy was...

Estimates of potential output and the neutral short-term interest rate play important roles in policy making. However, such estimates are associated with significant uncertainty and subject to significant revisions. This paper extends the structural multivariate filter methodology by adding a...

I carry out a business cycle accounting exercise (Chari, Kehoe and McGrattan, 2007) on theU.S. data measured in wage units (Farmer (2010)) for the entire postwar period. In contrast toa conventional approach, this approach preserves common medium-term business cyclefluctuations in GDP, its...
