This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

It is widely debated whether a monetary union has to be accompanied by a fiscal transfer scheme to accommodate asymmetric shocks. We build a model of a monetary union with a central bank and two heterogeneous countries that are linked by a fiscal transfer scheme with repercussions on monetary...

In this paper we propose an alternative explanation for the nature, sources and consequences of inflation rate differentials in a monetary union, such as EMU. To achieve this, we build on the new neoclassical synthesis (NNS) framework, recently advanced by Goodfriend (2002) and Goodfriend and...

Against the backdrop of the Greek three-act tragedy, we present a theoretical framework for studying Greece's recent debt and currency crisis. The model is built on two essential blocks: first, erratic macroeconomic policymaking in Greece is described using a stochastic regime-switching model;...

We assess the role of national fiscal policies, as automatic stabilizers, within a monetary union. We use a two-country New Keynesian DGE model which incorporates non-Ricardian consumers (as in Gali et al. 2004) and a home bias in the composition of national consumption bundles. We find that...

This paper employs a stylized New Keynesian DSGE model for a monetary union to analyze whether cyclical inflation differentials can be explained by cross-country differences concerning the characteristics of financial markets. Our results suggest that empirically plausible degrees of...

By using a model of trade union behaviour Grüner (2010) argues that the introduction of the European Monetary Union (EMU) led to lower wage growth and lower unemployment in participating countries. Following Grüner's model, monetary centralization lets the central bank react less flexibly to...

This study analyses the impact of economic catching-up on annual inflation rates in the European Union with a special focus on the new member countries of Central and Eastern Europe. Using an array of estimation methods, we show that the Balassa-Samuelson effect is not an important driver of...

We study optimal climate policy for a "policy bloc" of countries facing a market where emissions offsets can be purchased from a non-policy “fringe” of countries (such as for the CDM). Policy-bloc firms benefit from free quota allocations whose quantity is updated according to firms' past...

We build a tractable stylized model of external sovereign debt and endogenous international interest rates. In corrupt economies with rent-seeking groups stealing public resources, a politico-economic equilibrium is characterized by permanent fiscal impatience which leads to excessive issuing of...
