We propose a small open economy model where agents borrow internationally and invest in liquid foreign assets to insure against liquidity shocks, which temporarily shut out the economy of short-term credit markets. Due to the presence of a pecuniary externality individual agents borrow too much...

In the debate on global imbalances, the euro area countries did not receive much attention so far. While the current account is on balance for the entire area, divergences between individual member states have increased since the introduction of the common currency. In this paper, the imbalances...

This paper analyses empirically and theoretically the effects of uncertainty shocks on sovereign default risk. It describes a novel mechanism for non-fundamental debt crises induced by uncertainty shocks that are defined as time-varying levels of ambiguity surrounding the macroeconomic...

After 2008, the Southern European economies suffered a strong and persistent increase in unemployment. Rising government bond spreads necessitated the implementation of austerity policies. Austerity however, may increase unemployment. If workers lose human capital during unemployment spells, the...

Germany entered the euro with a current account deficit but over the entire past decade has run large and persistent current account surpluses. Besides joining the common currency, the increase of Germany's current account since the late 1990s has been accompanied by strong shifts in the...

Financial crises are usually preceded by large current account deficits. However, the channel through which international capital flows affect financial stability is hardly identified, yet. In this paper, we study the impact of current account balances on bank risk-taking making use of the...

Large trade imbalances have emerged as major policy challenges for the euro area within the last decade. As fiscal policy is the major macroeconomic policy instrument left with the individual member countries of EMU, fiscal devaluation is a highly debated policy tool to mimic the effects of an...

The paper scrutinizes the role of wages and capital flows for competitiveness in the new EU member states in the context of real convergence. For this purpose it extends the seminal Balassa-Samuelson model by international capital markets. The augmented Balassa-Samuelson model is linked to the...

This paper studies the role of financial market imperfections in the way countries' exports react to a currency depreciation. Using quarterly data for 27 developed and developing countries over the period 1990-2005, we show that the impact of a depreciation will be less positive - or even...

This paper analyses the importance of German wage moderation in the context of European imbalances. Using information from a New Keynesian small open economy model with labor market frictions, we derive sign restrictions for a wage markup shock. This information enables us to identify a German...
