Ph.D. Defence by Matthias Rottner
This thesis investigates topics in macroeconomics with nonlinear dynamics as their inherent feature. It aims to further the understanding of the connection between the financial sector and economic fluctuations, challenges of monetary policy in a low interest rate environment and how to mitigate the macroeconomic consequences of a pandemic.
The first chapter investigates the connection between the shadow banking sector and the vulnerability of the economy to a financial crisis.
The second chapter, joint with Francesco Bianchi and Leonardo Melosi, develops an asymmetric monetary policy strategy for a low real rate environment.
The third chapter, joint with Matthieu Darracq Paries and Christoffer Kok, analyses the connection between the reversal interest rate and macroprudential policies. The fourth chapter, joint with Leonardo Melosi, studies contact tracing in a new macro-epidemiological model with asymptomatic spreaders.
