In this paper, I introduce lumpy micro-level capital adjustment into a sticky information general equilibrium model. Lumpy adjustment arises because of inattentiveness in capital investment decisions instead of the more common assumption of non-convex adjustment costs. The model features...

Microeconomic lumpiness matters for macroeconomics. According to our DSGE model, it explains roughly 60% of the smoothing in the investment response to aggregate shocks. The remaining 40% is explained by general equilibrium forces. The central role played by micro frictions for aggregate...

This paper challenges the view that the observed negative correlation between the Federal Funds rate and the interest rate implied by consumption Euler equations is systematically linked to monetary policy. By using a Monte Carlo experiment, we show that stochastic risk premium disturbances have...

At the forefront of macroeconomic research on the causes of the Great Financial Cri- sis (GFC) was and still is the usage of dynamic stochastic general equilibrium (DSGE) models. To capture the nonlinearities of the GFC, these models were enriched with a variety of financial frictions. This...

Are uncertainty shocks a major source of business cycle fluctuations? This paper studies theeffect of a mean preserving shock to the variance of aggregate total factor productivity(macro uncertainty) and to the dispersion of entrepreneurs' idiosyncratic productivity (microuncertainty) in a...

The process of globalization encompasses economic and financial integration. Abolition of capital controls and dismantling of barriers of different kinds are important ingredients of the process that will entirely change the exposure of previously sheltered companies to shocks on the global...

We explore the implications of shocks to expected future productivity in a setting with limited enforcement of financial contracts. As in Lorenzoni andWalentin (2007) optimal financial contracts under limited enforcement imply that to obtain external finance firms have to post collateral in...

Is real investment fully determined by fundamentals or is it sometimes affected by stock market misvaluation? We introduce three new tests that: measure the reaction of investment to sales shocks for firms that may be overvalued; use Fama-MacBeth regressions to determine whether overinvestment...

Durch Bereitstellung von Krediten tragen Banken zur Transformation von Finanzkapital in Sachkapital bei. Die Kreditvergabepolitik der Schweizer Banken hat sich im vergangenen Vierteljahrhundert stark gewandelt. Basierend auf einem Datensatz (1987-2012) mit bankengruppenspezifischen Bilanzdaten...

The paper provides a systematic empirical analysis of the role of the housing market in the macroeconomy in the US and in the euro area. First, it establishes some stylised facts concerning key variables in the housing market, such as the real house price, residential investment and mortgage...
