This note documents a DSGE model of Climate Change. I extend the NK with geophysical variables, such as greenhouse gas emissions, carbon cycle, radiative forcing, and climate change. In this model, specify five different policy regimes: no policy, cap, intensive, tax, mandate.

Modern policy analysis makes extensive use of dynamic stochastic general equilibrium (DSGE) models. These models differ significantly from earlier generations of large-scale econometric models. I review what I see as major progress in the ability of economists to conduct model-based policy analysis. This progress has come through the evolution in the types of models being used and in a refineme...

Rational expectations are at the heart of the DSGE models maintained by central banks. A key equation which governs the evolution of prices in those models is the New Keynesian Phillips (NKPC) curve, in which today‟s rate of inflation is linked to expected future inflation. Expected future inflation is in turn modeled using rational expectations, which operationally means that forecast errors a...

This note corrects a mistake in the estimation algorithm of the time-varying structural vector autoregression model of Primiceri (2005) and proposes a new algorithm that correctly applies the procedure proposed by Kim, Shephard, and Chib (1998) to the estimation of VAR or DSGE models with stochastic volatility. Relative to Primiceri (2005), the correct algorithm involves a different ordering of...

In this paper, it is argued that the observed high positive correlation between national savings and investment which is found in the data can in part be explained by shocks to monetary policy. This hypothesis, which is established by reviewing some empirical findings, is tested in a two-country DSGE-model framework in the tradition of the New Open Economy Macroeconomics. The simulation results...

Abstract The current financial crisis highlights the need to develop DSGE models with real-financial linkages and an active banking sector. This paper proposes a fully micro-founded framework that incorporates optimizing banks, the interbank market, and the credit market into a DSGE model, and evaluates the role of banks and financial shocks in the U.S. business cycles. We assume two types of h...

This paper applies a new Bayesian framework laid out in Faust and Gupta (2009) for evaluating the suitability of dynamic stochastic general equilibrium (DSGE) models for the task of monetary policy analysis. The paper characterizes practical monetary policy analysis as determining how intended policy should be revised in light of the structural interpretation of incoming news. The news is defin...
