Welcome! I am a Ph.D. student in economics at DIW Berlin and the Macro research group at the Freie Universität Berlin. My research interests lie in macroeconomics and monetary economics. My current research focuses on understanding the transmission channel of monetary policy and the role of financial intermediaries in business cycle analysis.

My current work focuses on understanding the effects and transmission channels of monetary policy, and the role of financial frictions in business cycle analysis.

Monetary Policy and Household Net Worth (with Mathias Klein) R&R, Review of Economic Dynamics

Abstract: This study investigates the interrelation between household balance sheets, collateral constraints and monetary policy. Using data on the U.S. economy, we estimate a monetary DSGE model with financial frictions and occasionally binding borrowing constraints. We find that the level of household net worth best predicts the tightness of the borrowing constraint, which implies that monetary policy is more effective when net worth is low. We then test this model prediction on aggregate data and provide robust empirical evidence on asymmetric effects of monetary policy across the household net worth cycle that validates the model predictions. A contractionary monetary policy shock leads to a large and significant fall in economic activity during periods of low household net worth. In contrast, monetary policy shocks have only small and mostly insignificant effects when net worth is high.

Risk and State-dependent Financial Frictions (with Raf Wouters)

We augment a standard New Keynesian model with a financial accelerator mechanism and show that financial frictions generate large state-dependent amplification effects. We fit the model to U.S. data and show that the nonlinear model produces much stronger propagation of shocks than the linear model, particularly when shocks drive the model far away from the steady state. Importantly, we document that these amplification effects arise as a response to endogenous variation in financial conditions. Motivated by these findings, we propose a regime-switching DSGE framework where financial frictions endogenously fluctuate between moderate (low risk) and severe (high risk) depending on the state of the economy. This framework allows for efficient estimation with many state variables and improves fit with respect to the linear model.

Work in progress

Household Credit Constraints and the Transmission of Monetary Policy to Consumption

In this paper I combine two rich surveys for the US (the SCF and CEX) and exploit these detailed household portfolio and consumption data to assess the role of household credit constraints for the transmission channel of monetary policy to consumption. In contrast to most approaches in the literature, I exploit an explicit measure of credit constraints from the SCF, where households report whether they have gotten loans partially or fully rejected. I show that this type of household credit constraints significantly dampen the effectiveness monetary policy.
