This paper examines optimal monetary policy under heterogeneous expectations. To this end, we develop a stochastic New Keynesian model with a cost-push shock and coexistence of one-step-ahead rational and adaptive expectations in decentralized markets. On the one side, heterogeneous expectations...

We analyze the long-run growth effects of automation in the canonical overlapping generations framework. While automation implies constant returns to capital within this model class (even in the absence of technological progress), we show that it does not have the potential to lead to positive...

This paper develops a theory of endogenously (non-)Ricardian beliefs. That is, whether Ricardian Equivalence holds in an equilibrium depends on endogenous private sector beliefs. The novelty here is a restricted perceptions viewpoint: in complex forecasting environments, agents forecast...

This paper examines whether Euro Area countries would have faced a more favorable inflation output variability tradeoff without the Euro. We provide evidence that this claim is true for the periods of the Great Recession and the European Sovereign Debt Crisis. For the Euro Area as a whole, the...

Die vorliegende kumulative Dissertation umfasst drei Essays, welche sich mit Fragestellungen der Geld- und Fiskalpolitik beschäftigen. Jeder Essay stellt ein Kapitel der Dissertation dar. Das erste Kapitel trägt den Titel "Heterogeneous Expectations and the Merit of Monetary Policy Inertia."...

We estimate state-dependent government spending multipliers for the United States. We use a Factor-Augmented Interacted Vector Autoregression (FAIVAR) model. This allows us to capture the time-varying monetary policy characteristics including the recent zero interest rate lower bound (ZLB)...

We assess the long-run growth effects of automation in the overlapping generations framework. Although automation implies constant returns to capital and, thus, an AK production side of the economy, positive long-run growth does not emerge. The reason is that automation suppresses wage income,...

We analyze the long-run growth effects of automation in the standard overlap- ping generations framework. We show that, in contrast to other neoclassical models of capital accumulation, automation does not promote growth but induces economic stagnation. The reason is that automation suppresses...
