This paper develops an algorithm that enables to solve macroeconomic models with Rotemberg pricing and imperfect common knowledge. Under the concept of imperfect common knowledge, Rotemberg pricing requires the solution algorithm to take prices explicitly into account. The state space includes...

This documentation concisely describes the dynamic stochastic general-equilibrium model that the ifo Institute currently uses for simulations and business-cycle analysis. The model consists of three countries and contains a wide range of rigidities. The model is regularly estimated by quarterly...

This paper analyzes the macroeconomic impact of corporate taxation. The analysis is conducted in a quantitative two-country model. In the first step, the paper describes the long-run effects of corporate taxation. A reduction in the corporate-income tax rate increases GDP, wages, consumption,...

I derive the imperfect-common-knowledge Phillips curve under the assumption of Rotemberg pricing. The curve differs from the Calvo version in one important aspect. Expectations of future relative prices impact in ation.
