In the present paper we analyse whether fundamental macroeconomic factors, temporary influences or more structural factors have contributed to the recent decline in bond yields in the US. For that purpose, we start with a very general model of interest rate determination in which risk premia are...

We develop an algorithm to construct approximate decision rules that are piecewise-linear and continuous for DSGE models with an occasionally binding constraint. The functional form of the decision rules allows us to derive a conditionally optimal particle filter (COPF) for the evaluation of...

We introduce a high-dimensional structural time series model, where co-movement between the components is due to common factors. A two-step estimation strategy is presented, which is based on principal components in differences in a first step and state space methods in a second step. The...
