House-purchasing decisions and the possibility of existing homeowners to tap into their housing equity depend decisively on prevailing loan-to-value (LTV) ratios in mortgage markets with borrowing constrained households. Utilizing a smooth transition local projection (STLP) approach, I show that...

We investigate the e ect of monetary policy on European macroeconomic variables using a small-scale vector autoregression (VAR) and the "Effective Monetary Stimulus" (EMS). The EMS is a monetary policy metric obtained from yield curve data that is designed to consistently reflect the overall...

We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-differences within the structural gravity model. To test the ETWFE, we estimate the effects of regional trade agreements (RTAs). The results suggest that RTA estimates in the current gravity literature may be...

We study the cyclicality of public R&D in 28 OECD countries (1995-2017). While procyclical on average, public R&D reacts asymmetrically over different phases of the business cycle and becomes acyclical during recessions. It is also heterogeneous across countries: Innovation leaders and followers...

We simulate the fiscal stimulus packages set up by the German government to allevi-ate the costs of the COVID-19 pandemic in a dynamic New Keynesian multi-sectorgeneral equilibrium model. We find that, cumulated over 2020-2022, output lossesrelative to steady state can be reduced by more than 4...

We analyze the effect of the geographic expansion of banks across U.S. states on the co-movement of economic activity between states. Exploiting the removal of interstate banking restrictions to construct time-varying instrumental variables at the state-pair level, we find that bilateral banking...
