We analyze the sources of current account fluctuations for the G6 economies. Based on Bergin and Sheffrin’s (2000) two-goods inter-temporal framework, we build a SVAR model including the world real interest rate, net output, real exchange rate, and the current account. The theory model allows...

We investigate the time variation in the correlation between hours and technology shocks using a structural business cycle model. We propose an RBC model with a Constant Elasticity of Substitution (CES) production function that allows for capital- and labor-augmenting technology shocks. We...

DSGE models are typically estimated assuming the existence of certain structural shocks that drive macroeconomic fluctuations. We analyze the consequences of introducing nonfundamental shocks for the estimation of DSGE model parameters and propose a method to select the structural shocks driving...

German labor market reforms in the 1990s and 2000s are generally believed to have driven the large increase in the dispersion of current account balances in the Euro Area. We investigate this hypothesis quantitatively. We develop an open economy New Keynesian model with search and matching...

The reaction of hours worked to technology shocks represents a key controversy between RBC and New Keynesian explanations of the business cycle. It sparked a large empirical literature with contrasting results. We demonstrate that, with a more general and data coherent supply and production...

We analyze how trade affects aggregate volatility using a multi-country, multiindustry, and multi-destination framework. We decompose aggregate output growth risk into destination risk, origin risk, and idiosyncratic risk (and their covariances). We then use this framework to run counterfactuals...
