This paper re-examines the role of real supply shocks in international business cycles. In contrast to previous studies, we extend the concept of supply shocks beyond the productivity shock towards labor supply shocks. Our analysis simultaneously identifies five real and nominal disturbances in...

In 2009, Germany invested 15.4 Billion Euro in infrastructure to avert the looming recession. In this study, we evaluate whether the German stimulus program was successful in limiting the impact of the crisis on the job market. We exploit exogenous cross-sectional variation to identify the...

We re-examin the notion of identifying macroeconomic effects using the narrative approach taking as an application the estimation of tax multipliers. We point out to a test for the checking the adequacy of regressing the narrative measure directly on the outcome variable. This test...

We provide a systematic analysis of fiscal consolidation in a dynamic general equilibrium model with a detailed government sector and a share of credit-constrained households. We simulate permanent cuts in government consumption, government investment, and transfer payments as well as permanent...

Using VAR analysis on US data, we show that unanticipated fiscal expansions boost private consumption and business formation. Models with an extensive investment margin, i.e. endogenous firm and product entry, have difficulties explaining these two phenomena simultaneously. Considering different...

Growth is associated with (i) shifts in the sectoral structure of the economy, (ii) changes in relative prices and (iii) the Kaldor facts. Moreover, (iv) cross-sectional data shows systematic differences in the expenditure structure across income groups. This paper presents a growth model which...
