We investigate whether the macroeconomic effects of government spending shocks vary with the level of uncertainty. Using postwar US data and a Self-Exciting Interacted VAR (SEIVAR) model, we find that fiscal spending has positive output effects in tranquil times but is contractionary during...

Central bank announcements have strong effects on interest rates, but small or even counterintuitive effects on economic expectations. Based on tick-by-tick futures prices on bonds and stock prices, I confirm these seemingly puzzling results for the euro area and provide evidence that they are...

This paper investigates how the ordering of variables affects properties of the time-varying covariance matrix in the Cholesky multivariate stochastic volatility model. It establishes that systematically different dynamic restrictions are imposed when the ratio of volatilities is time-varying....

This paper puts forward a Bayesian version of the global vector autoregressive model (B-GVAR) that accommodates international linkages across countries in a system of vec-tor autoregressions. We compare the predictive performance of B-GVAR models for the one- and four-quarter ahead forecast...

We analyze differences in consumption and wealth that arise because of different degrees of rationality of households. In particular, we use a standard New Keynesian model and let a certain fraction of households be fully rational while the other fraction possesses less cognitive ability. We...

We estimate the effects of monetary policy on price-setting behavior in administrative micro data underlying the German producer price index. After expansionary monetary policy, the increase in the frequency of price change is economically small, the average absolute size across all price...

The present paper studies the effect of monetary policy on inflation and output within a New Keynesian model with Experience-Based Learning (EBL) that renders expectations heterogeneous across age groups. Under EBL, the age-distribution directly affects the composition of aggregate expectations...

We study the driving forces of the so-called "German labor market miracle" the trend-shift and steady decline of German unemployment over the last two decades that persisted beyond the Great Recession. Our structural VAR approach encompasses various factors within a single comprehensive...

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...

This paper theoretically analyzes the macroeconomic effects of gender discrimination against women in the labor market in a New Keynesian model. We extend standard frameworks by including unpaid household production in addition to paid labor market work, by assuming that the representative...
