The Macroeconomic Effects of Quantitative Easing in the Euro Area: Evidence from an Estimated DSGE Model

This paper analyses the macroeconomic effects of the ECB's quantitative easing programme using an open-economy DSGE model estimated with Bayesian techniques. Using data on government debt stocks and yields across maturities we identify the parameter governing portfolio adjustment in the private sector. Shock decompositions suggest a positive contribution of ECB QE to EA year-on-year output growth and inflation of up to 0.4 and 0.5 pp in the standard linearised version of the model. Allowing for an occasionally binding zero-bound constraint by using piecewise linear solution techniques raises the positive impact up to 1.0 and 0.7 pp, respectively.
