Unconventional Monetary Policy in the United States : An empirical study of the quantitative easing (QE) effects on households and firms

Abstract: Quantitative Easing is an unconventional instrument when conducting monetary policy with the aim of stimulating the economy. The instrument is a complementary tool when changing the nominal interest rate is no longer effective. In the United States this unconventional instrument has been used through three different waves between December 2008 to October 2014. This research paper investigates two different regressions, one for the dependent variable consumption and one for the dependent variable investments to capture the effects on households and firms respectively. The results are used to study whether the unconventional monetary policy has had any effects on these variables and if the dependent variables are affected to different degrees. Data for this paper is collected between the first quarter of 2005 until the fourth quarter of 2019. The modelling used is the Auto Regressive Distributed Lag Model (ARDL) for the two different regressions. All variables in the regressions are critically tested for unit roots, autocorrelation, heteroscedasticity and misspecification to validate the analysis. The findings of our ARDL models indicate that investments are affected by quantitative easing to a larger degree than consumption by 3.8 times the change of the coefficients at its optimal lags.
