Die deutsche Wirtschaft ist im dritten Quartal 2018 geschrumpft. Grund hierfür waren die Produktionsrückgänge im Automobilsektor infolge von Zulassungsstockungen. Dies wird zwar zu Nachholeffekten führen, das Wirtschaftswachstum wird sich in Deutschland in diesem Jahr allerdings nur noch auf...

The consumption boom-bust cycle in the 2000s coincided with large fluctuations in the volume of home equity borrowing. Contrary to conventional wisdom, I show that homeowners largely borrowed for residential investment and not consumption. I rationalize this empirical finding using a calibrated...

This paper examines the effects of time-varying volatility on welfare. I construct a tractable endogenous growth model with recursive preferences, stochastic volatility, and capital adjustment costs. The model shows that a rise in volatility can decelerate growth in the absence of any level...

This paper revisits the personal expenditure tax (PET), the most prominent version of a progressive consumption tax. The PET has a long intellectual tradition in economics, and the merits and demerits of this alternative to the personal income tax have been discussed at length. What has been...

This paper shows that increased volatility of Örm-level productivity can push the nominal interest rate to its lower bound with large amplification effects on macroeconomic aggregates. The framework combines a simple canonical Önancial accelerator model, time varying risk shocks, and a zero...

A common prediction of macroeconomic models of credit market frictions is that the tightness of financial constraints is countercyclical. As a result, theory implies a negative collateralizability premium; that is, capital that can be used as collateral to relax financial constraints provides...

Die weltwirtschaftlichen Rahmenbedingungen haben sich verschlechtert. Die protektionistische Tonart der US-Administration provoziert einen globalen Handelskonflikt. Dieser kann weitere Problemlagen wie eine Finanzmarktkrise in China oder in Europa auslösen. Nicht zuletzt gefährden auch die...

In a series of summits, leading countries of the world will meet to draw up an international arrangement for financial stability. Such a rule system should prevent a financial crisis as we have seen it in 2007 and 2008. It should include appropriate principles of monetary policy, rules for...

This paper has two aims. First, it provides simple theoretical models that highlight two channels whereby monetary shocks have permanent real effects and the interactions between these channels. Second, it presents an empirical dynamic model, covering a panel of EU countries, and derives the...

This paper shows that the interaction between money growth and staggered nominal contracts gives rise to a long-run inflation-unemployment tradeoff.
