We study how monetary policy may affect determinacy and expectational stability (E-stability) of rational expectations equilibrium when the cost channel of monetary policy matters. Focusing on instrumental Taylor-type rules and optimal target rules, we show that standard policies can induce...

This paper evaluates under which conditions different Taylor-type rules lead to determinacy and expectational stability (E-stability) of rational expectations equilibrium in a simple "New Keynesian" small open economy model, developed by Gali and Monacelli (2005). In particular, we extend...

This paper analyzes how terms of trade affect aggregate productivity using a two-country monopolistic competitive business cycle model driven by aggregate technology shocks. The inefficiency of the equilibrium implies that each country’s productivity is affected by the terms of trade. This...

We evaluate the second order solution of a general equilibrium model for a small open economy in the line of the "new open economy macroeconomics". We use this framework to explain some recent regularities observed in economies in which central banks move from using a money aggregate as the...

It is accepted that standard macroeconomic variables are not capable of predicting ex ante the majority of short term changes in exchange rates. Lettau and Ludvigson (2001) find that fluctuations in the common long-term trend in consumption, asset wealth, and labour income (hereby,...

We develop a small open economy general equilibrium model with sticky prices and partial dollarization -- a situation where both domestic and foreign currencies coexist. We derive a tractable representation of the model in terms of domestic inflation and the output gap in which a trade-off,...
