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...

I study whether monetary gold hoarding was the main cause of the Great Depression in a structural VAR analysis. The notion that monetary forces played an important role in bringing about the depression is well established in the narrative literature, but has more recently met some skepticism by...

This paper studies the ability of manufacturing-specific shocks to explain global oil prices. In an estimated three-region DSGE model (UnitedStates, OPEC, rest-of-world) in corporating two sectors (manufacturing and services) in the oil-importing economies and featuring cross-border...

We study the link between the global financial cycle and macroeconomic tail risks using quantile vector autoregressions. Contractionary shocks to financial conditions and monetary policy in the United States cause elevated downside risks to growth around the world. By tightening financial...

This research develops an expanded unified growth theory that incorporates the endogenous accumulation of physical capital, population, human capital, and technology. The model incorporates a complementarity between physical capital and human capital and can be extended to a multi-country...

This paper reconsiders the labor market consequences of structural change over the past 43 years. Taking two different ways of defining manufacturing and service employment as point of departure - according to the industry classification of firms or establishments and according to the occupation...

We examine the effects of increased international integration of both goods and financial markets on business cycle dynamics. To do so, we develop a new econometric framework for modelling cross-country spillovers in which the magnitude of these spillovers is an empirically determined function...

Motivated by the build-up of shadow bank leverage prior to the financial crisis of 2007-2008, I develop a nonlinear macroeconomic model featuring excessive leverage accumulation and endogenous financial crises to capture the observed dynamics and to quantify the build-up of financial fragility....

The "Great Lockdown" implemented in response to the COVID-19 pandemic has led to a severe world-wide economic crisis. In euro area countries, sovereign debt-to-GDP ratios are on the rise and reductions in expected fiscal surpluses raise sustainability concerns amongst investors. This paper...

We propose a structural vector-autoregressive model for the German natural gas market to investigate the impact of the 2022 Russian supply stop on the German economy. We combine conventional and narrative sign restrictions to leverage information about supply cuts for identification and find...
