Accounting for the pervasive evidence of limited international risk sharing is an important hurdle for open-economy models, especially when these are adopted in the analysis of policy trade-offs likely to be affected by imperfections in financial markets. Key to the literature is the evidence,...

This paper investigates the international transmission of productivity shocks in a sample of five G7 countries. For each country, using long-run restrictions, we identify shocks that increase permanently domestic labour productivity in manufacturing (our measure of tradables) relative to an...

This Paper provides a baseline general-equilibrium model of optimal monetary policy among interdependent economies with monopolistic firms and nominal rigidities. An inward-looking policy of complete domestic output stabilization is not optimal when firms' markups are exposed to currency...

This Paper proposes a new framework for interpreting a currency crisis associated with a fiscal imbalance, which we find appropriate for the analysis of contemporary economies with outstanding public debt. Unlike the first-generation literature on speculative attacks, we do not assume that money...

This paper develops a quantitative, dynamic, open-economy model which endogenously generates high exchange rate volatility, whereas a low degree of exchange rate pass-through (ERPT) stems from both nominal rigidities (in the form of local currency pricing) and price discrimination. We model real...

In this paper, we study the co-movement of the government budget balance and the trade balance at business cycle frequencies. In a sample of 10 OECD countries we find that the correlation of the two time series is negative, but less so in more open economies. Moreover, for the US the...

'New open economy macroeconomics' (NOEM) refers to a body of literature embracing a new theoretical framework for policy analysis in open economy, aiming to overcome the limitations of the Mundell-Fleming model while preserving the empirical wisdom and policy friendliness of traditional...

The joint dynamics of US net output, consumption, and (valuation-adjusted) foreign assets and liabilities, characterized empirically following Lettau and Ludvigson [2004], is shown to be strikingly consistent with current account theory. While US consumption is virtually insulated from...

What can be learnt from revisiting the Optimal Currency Areas (OCA) theory 50 years from its birth, in light of recent advances in open economy macro and monetary theory? This paper presents a stylized micro-founded model of the costs of adopting a common currency, relative to an ideal benchmark...

Do large investors increase the vulnerability of a country to speculative attacks in the foreign exchange markets? To address this issue, we build a model of currency crises where a single large investor and a continuum of small investors independently decide whether to attack a currency based...
