In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a twosector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained...

We use a standard new Keynesian model to evaluate the cost of disinflation - measured by the sacrifice ratio, the central bank's loss function, and the welfare cost - in a small open economy vis-à-vis a closed economy. Disinflation is either more costly or less beneficial in the small open...

Conventional empirical models of monetary policy transmission in emerging market economies produce puzzling results: monetary tightening often leads to an increase in prices (the price puzzle) and depreciation of the currency (the FX puzzle). We show that incorporating forward-looking...
