Polynomial chaos expansion (PCE) provides a method that enables the user to represent a quantity of interest (QoI) of a model's solution as a series expansion of uncertain model inputs, usually its parameters. Among the QoIs are the policy function, the second moments of observables, or the...

Polynomial chaos expansion (PCE) provides a method that enables the representation of a random variable, the quantity of interest (QoI), as a series expansion of other random variables, the inputs. Traditionally, uncertain parameters of the model are treated as random inputs, and the QoI is an...

The risk premium puzzle is even worse than previously reported if housing is also taken into consideration next to equity. While housing premia are only moderately smaller than equity premia, they are significantly less volatile and the Sharpe ratio of housing is significantly larger. Hence,...

We take the neoclassical perspective and apply the business cycle accounting method as proposed by Chari, Kehoe, and McGrattan (2007, Econometrica) for the Great Recession and the associated stimulus program in Germany 2008-2009. We include wedges to the variables government consumption,...

In this paper, I present a multi-sectoral DSGE-model with housing, real rigidities and variable capital utilization that generates aggregate and sectoral co-movements due to sector specific shocks. Furthermore, the model accounts for two puzzles: First, residential investment correlates...
