Inflation dynamics in a small open economy model under inflation targeting: some evidence from Chile
Following the influential work of Christiano, Eichenbaum, and Evans (2005) and Smets and Wouters (2003), many central banks are building and estimating dynamic stochastic general equilibrium (DSGE) models with nominal rigidities and are using them for policy analysis. This new generation of sticky ...
Optimal monetary policy rules when the current account matters
