Recent data show substantial increases in the size of gross external asset and liability positions. The implications of these developments for optimal conduct of monetary policy are analyzed in a standard open economy model which is augmented to allow for endogenous portfolio choice. The model...

We present a simple behavioral model with chartists and fundamentalists and analyze their trading behavior in a floating regime and in a target zone regime. Regarding the floating regime the model replicates the well-known stylized facts like excessive volatility, fat tails, volatility...

Empirical evidence suggests that a monetary shock induces the exchange rate to overshoot its long-run level. The estimated magnitude and timing of the overshooting, however, varies across studies. This paper generates delayed overshooting in a new Keynesian model of a small open economy by...

Between 1990 and 2001 the Argentine peso appreciated by 80 percent in real terms, and its overvaluation has been singled out as one of the main suspects in the debate on the causes of the Argentina collapse of late 2001. This paper assesses the degree of real misalignment in Argentina over the...

Pre-Accession Transition Countries (PATCs) aim at early admittance to the monetary club. Their fiscal indicators – deficit and debt - do not show any serious symptoms. Closer scrutiny reveals, however, that the interest burden of their public debt might be underestimated, and that...

We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these...

The question as to whether changes in the external environment may have caused the importance of key determinants of German exports to shift since the 1990s is addressed by estimating Germany's exports to EMU partner countries (intra exports) and to countries outside the euro area (extra...

This paper analyzes the international monetary transmission mechanism in economies with portfolio rigidities. In a general equilibrium monetary model with distribution costs in trade, I analyze the reaction of the economy to technology, money supply and government spending shocks, and the...

A simple method to estimate multilateral equilibrium real exchange rates in a cointegration framework is used to compute the equilibrium real exchange rate for the peseta. The stock of foreign assets and the evolution of sectoral prices have been considered to be the fundamentals for the real...

In this paper we construct a dynamic stochastic general equilibrium model for a small open economy allowing for perfect capital mobility. The model incorporates price rigidities in monopolistically competitive goods and labor markets and real rigidities in the form of capital adjustment costs....
