On DSGE Models

Lawrence J. Christiano Martin S. Eichenbaum Mathias Trabandt

in: Journal of Economic Perspectives , im Erscheinen


Macroeconomic policy questions involve trade-off s between competing forces in the economy. The problem is how to assess the strength of those forces for the particular policy question at hand. DSGE models are the leading framework that macroeconomists have for dealing with this problem in an open and transparent manner. This paper reviews the state of DSGE models before the nancial crisis and how DSGE modelers have responded to the crisis and its aftermath. In addition, we discuss the role of DSGE models in the policy process.

Should We Use Linearized Models To Calculate Fiscal Multipliers?

Jesper Lindé Mathias Trabandt

in: Journal of Applied Econometrics , im Erscheinen


We calculate the magnitude of the government consumption multiplier in linearized and nonlinear solutions of a New Keynesian model at the zero lower bound. Importantly, the model is amended with real rigidities to simultaneously account for the macroeconomic evidence of a low Phillips curve slope and the microeconomic evidence of frequent price changes. We show that the nonlinear solution is associated with a much smaller multiplier than the linearized solution in long-lived liquidity traps, and pin down the key features in the model which account for the di¤erence. Our results caution against the common practice of using linearized models to calculate …scal multipliers in long-lived liquidity traps.

The Macroeconomic Risks of Undesirably Low Inflation

Mathias Trabandt Jonas Arias Christopher J. Erceg

in: European Economic Review , 2016


This paper investigates the macroeconomic risks associated with undesirably low inflation using a medium-sized New Keynesian model. We consider different causes of persistently low inflation, including a downward shift in long-run inflation expectations, a fall in nominal wage growth, and a favorable supply-side shock. We show that the macroeconomic effects of persistently low inflation depend crucially on its underlying cause, as well as on the extent to which monetary policy is constrained by the zero lower bound. Finally, we discuss policy options to mitigate these effects.
