Motivated by the Chinese experience, we analyze a semi-open economy where the centralbank has access to international capital markets, but the private sector has not. Thisenables the central bank to choose an interest rate different from the international rate.We examine the optimal policy of...

In the recent decade, capital outows from emerging economies, in the form of a demandfor liquid assets, have played a key role in the context of global imbalances. In this paper,we model the demand for liquid assets by rms in a dynamic open-economy macroeconomicmodel. We nd that the implications...

This paper studies how liability dollarization conditions the effectof exchange rate exibility on growth. It develops a model with creditconstrainedrms facing liquidity shocks denominated in tradables while theirrevenues are both in tradable and nontradables. With frictions in the...

Recent research has shown that relaxing the assumptions of complete informationand common knowledge in exchange rate models can shed light on a wide range ofimportant exchange rate puzzles. In this chapter, we review a number of models wehave developed in previous work that relax the strong...
