Deflationary vs. inflationary expectations : a new-Keynesian perspective with heterogeneous agents and monetary believes
(2009) Sauter, Oliver; Geiger, Felix
We expand a standard New-Keynesian model by allowing for a special role of money in the inflation and expectations building process. Motivated by the two-pillar Phillips curve, we introduce heterogeneous expectations. Thereby a fraction of agents forms inflation expectations by observing trend money growth. We show that in the presence of these monetary believers, contractive shocks to the economy produce smoother dynamics for inflation and output. We also find that monetary policy should follow a conventional Taylor rule with contemporaneous inflation and output data, if it is uncertain about the fraction of monetary believers.
International interest-rate risk premia in affine term structure models
(2009) Geiger, Felix
I estimate a Gaussian two-factor affine term structure model of bond yields for three countries, the United States, the United Kingdom and Germany. I find a considerable time-varying component of excess returns in the data. They are positively correlated with the slope of the term structure and negatively with the short-term policy rate. In addition, the panel clearly indicates to co-movements in the same directions on an international level. When testing the estimated model for the expectations puzzle of the the term structure, at least at one end of the yield curve, this puzzle can be resolved when applying risk-adjusted yield changes.
The camp view of inflation forecasts
(2009) Schmid, Kai Daniel; Sauter, Oliver; Geiger, Felix
Analyzing sample moments of survey forecasts, we derive disagreement and un- certainty measures for the short- and medium term inflation outlook. The latter provide insights into the development of inflation forecast uncertainty in the context of a changing macroeconomic environment since the beginning of 2008. Motivated by the debate on the role of monetary aggregates and cyclical variables describing a Phillips-curve logic, we develop a macroeconomic indicator spread which is assumed to drive forecasters? judgments. Empirical evidence suggests procyclical dynamics between disagreement among forecasters, individual forecast uncertainty and the macro-spread. We call this approach the camp view of inflation forecasts and show that camps form up whenever the spread widens.
