This paper develops an environmental dynamic stochastic general equilibrium (E-DSGE) model with heterogeneous production sectors. In particular, the model comprises some low-carbon emission firms that finance their investments and production only through banking loans, and high-carbon emission...

We study the preferential treatment of green bonds in the Central Bank collateral framework as an environmental policy instrument. We propose a macroeconomic model with environmental and financial frictions, in which green and conventional entrepreneurs issue defaultable bonds to banks that use...

In 2019, Sweden's central bank, the Riksbank, sold carbon-heavy bonds from its foreign exchange reserves. This act led to the Riksbank being labelled a frontrunner in what has been referred to as green central banking (GCB). The growing interest in proactive central banking has led to a wealth...

We study the implications of climate change and the associated mitigation measures for optimal monetary policy in a canonical New Keynesian model with climate externalities. Provided they are set at their socially optimal level, carbon taxes pose no trade-offs for monetary policy: it is both...

We study the interaction between monetary and fiscal policies in a Ramsey-Sidrauski model augmented with environmental capital. Equilibrium solutions are studied through the "Green Golden Rule". Despite the non-separability of money in utility and intertemporally nonseparable preferences, money...

We study the effects of a temporary Green QE, defined as a policy that temporarily tilts the central bank's balance sheet toward green bonds, i.e. bonds issued by firms in non-polluting sectors. To this purpose, we merge a standard DSGE framework with an environmental model. In our model,...
