Welcome to my website!

I am a Ph.D. Student at the Institute for Economic Theory II (Macro) at Humboldt-Universität zu Berlin and participate in the Berlin Doctoral Program in Economics and Management Science. My main research interests are: macroeconomics, macro-finance, uncertainty, international economics and numerical methods.

I am on the market in 2018/19 and will be available for interviews at the EEA Job Market Meeting in Naples, SAEe Meeting in Madrid and ASSA Meeting in Atlanta.

Macroeconomic Effects of Financial Uncertainty (Job Market Paper)

Abstract: This paper investigates the macroeconomic effects of uncertainty originating in the financial sector. To this end, I first document empirical relevance of financial uncertainty using SVAR methods. Then, I employ the DSGE framework developed by Gertler and Karadi (2011) to uncover the underlying transmission mechanism. The model generates macroeconomic dynamics that are consistent with the SVAR evidence. In particular, an increase in financial uncertainty raises the risk premium and leads to a decline in output, consumption, investment and hours worked. This outcome arises mainly because of an endogenous tightening of the financial constraint, which in turn triggers the financial accelerator mechanism. Finally, internal habit formation and nominal rigidities act as additional amplification mechanisms for financial uncertainty shocks.
