Using new narrative measures of exogenous variation in marginal tax rates associated with postwar tax reforms in the US, this study estimates short run tax elasticities of reported income of around 1.2 based on time series from 1946 to 2012. Elasticities are larger in the top 1% of the income...

We provide a condition which is both necessary and sufficient for uniform validity of asymptotic approximations using the delta-method, that is for uniform negligibility of the remainder of such approximations. This condition is easily verified and permits to identify settings and parameter...

In der Wissensmanagementforschung wird dem Wissenstransferprozess besondere Aufmerksamkeit geschenkt: Wissenstransfer sichert die Lernfähigkeit und das Innovationspotential und trägt damit zur Wettbewerbs- und Überlebensfähigkeit von Organisationen bei. Obwohl der Wissenstransfer von den...

Wie könnte die Alterssicherung im Jahr 2030 aussehen? Diese Arbeit verbindet die privaten Haushalte, den Produktionssektor, die Rentenversicherung und die Bevölkerungsentwicklung in einem allgemeinen Gleichgewichtsmodell und analysiert die makroökonomischen Auswirkungen des demographischen...

We propose a novel identification design to estimate the causal effects of systematic monetary policy on the propagation of macroeconomic shocks. The design combines (i) a time-varying measure of systematic monetary policy based on the historical composition of hawks and doves in the Federal...

We document three new empirical facts: (i) monetary policy shocks increase the markup dispersion across firms, (ii) they increase the relative markup of firms with stickier prices, and (iii) firms with stickier prices have higher markups. This is consis- tent with a New Keynesian model in which...

Using quarterly worker flow data of U.S. establishments, we find that an unexpected increase in uncertainty reduces hirings and quits, while it raises layoffs. This finding suggests that the real option effect of uncertainty is less important for employment decisions. Hence plants do not freeze...

Following the real option literature, whether or not uncertainty shocks drive business cycles depends on the degree of adjustment frictions. The more plants freeze and remain inactive in response to increased uncertainty, the stronger the adverse effects on the economic activity. Using quarterly...

Investment is central for business cycles and a key characteristic of investment is time to build (TTB). I document that TTB is volatile and largest during recessions. To study these fluctuations, I develop a model. In the model, the longer TTB, the less frequently firms invest, and the less...
