Whatever it takes to save the planet? Central banks and unconventional green policy
Abstract We study the transmission mechanism of a Green QE, defined as a policy that tilts the central bank’s balance sheet toward green bonds, that is bonds issued by non-polluting firms. We merge a DSGE framework with an environmental model, in which CO2 emissions increase the stock of atmospheric carbon, which in turn decreases total factor productivity. Imperfect substitutability between green and brown bonds is a necessary condition for the effectiveness of Green QE. However, even under this assumption, the effect of Green QE in reducing emissions is negligible and in some cases close to nil.
期刊介绍:
Macroeconomic Dynamics publishes theoretical, empirical or quantitative research of the highest standard. Papers are welcomed from all areas of macroeconomics and from all parts of the world. Major advances in macroeconomics without immediate policy applications will also be accepted, if they show potential for application in the future. Occasional book reviews, announcements, conference proceedings, special issues, interviews, dialogues, and surveys are also published.
