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 develop a New Keynesian (NK) model with endogenous price setting frequency. Whether a firm updates its price in a given period depends on an analysis of expected cost and benefits modelled by a discrete choice process. A firm decides to update the price when expected benefits outweigh...

We estimate government spending multipliers in demand- and supply-driven recessions for the Euro Area. Multipliers in a moderately demand-driven recession are 2-3 times larger than in a moderately supply-driven recession, with the difference between multipliers being non-zero with very high...

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...

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...
