A small open economy model is presented, which allows explicit treatment of uncertainty and its effects on macroeconomic behaviour. Inflation targeting is compared to the welfare maximizing monetary rule and to a fixed nominal exchange rate. It is found that flexible inflation targeting produces...

I revisit the potential costs and benefits for Sweden of joining the Economic and Monetary Union (EMU) of the European Union. I first show that the Swedish business cycle since the mid-1990s has been closely correlated with the Euro area economies, suggesting that common shocks have been an...

A two-country dynamic general-equilibrium model with imperfect competition and price stickiness is considered. This work shows the conditions under which price stability can implement the flexible-price allocation as a Nash equilibrium. This is possible if and only if both countries maintain a...

We examine optimal policy in a two-country model with uncertainty and learning, where monetary policy actions affect the real economy through the real exchange rate channel. Our results show that whether policy should be cautious or activist depends on the size of one country relative to...

This paper explores the role of trade integration - or openness - for monetary policy transmission in a medium-scale new Keynesian model. Allowing for strategic complementarities in price-setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts...

This paper considers the effects of fiscal and financial policy on economic growth in open and closed economies, when human capital formation by young households is constrained by the illiquidity of human wealth. Both endogenous and exogenous growth versions of the basic OLG model are analysed....

The paper presents new stylized facts on the direction of capital flows. We find (i) international capital flows net of government debt and/or official aid are positively correlated with growth; (ii) sovereign debt flows are negatively correlated with growth only if debt is financed by another...

There are two main forces behind the large US current account deficits. First, an increase in the US demand for foreign goods. Second, an increase in the foreign demand for US assets. Both forces have contributed to steadily increasing current account deficits since the mid-1990s. This increase...

Estimates of the elasticity of substitution between domestic and foreign varieties are small in macroeconomic data, and substantially larger in disaggregated studies. This may be an artifact of heterogeneity. We use disaggregated multilateral trade data to structurally identify elasticities of...

We study the determinants of net capital income flows within the United States. We analyze a simple multi-state neoclassical model in which total factor productivity varies across states and over time and capital flows freely across state borders. The model predicts that capital will flow to...
