Available evidence supports the view that growth is faster in more open economies. In order to analyze the implications of openness and growth on determinacy and learnability of worldwide rational expectations equilibria we develop a two-country New Keynesian model with growth. We analyze these...

The EU's macroeconomic surveillance mechanism, namely the Macroeconomic Imbalance Procedure (MIP), is based on the so-called Scoreboard, which comprises a set of indicators that serve as a signalling device for potentially harmful macroeconomic developments. We first evaluate the early warning...

Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A stickyprice model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

EU Member countries have shown different degrees of ambition to reach a budget position of "close to balance or in surplus". Differences in ambition can only partly be explained by the relative size of cyclical safety mar­gins or differences in the number of votes in the ECOFIN Council. It is...

A small expectations-expanded "Mundell-Fleming" model is built for the European Union Accession Countries and estimated to assess the optimality of different exchange rate regimes (a peg and a float) through a simple welfare function. Floating appears as the best option for most of the countries...

Almost half of the world's states provide bilateral development assistance. While previous research takes the set of donor countries as exogenous, this article is the first to explore the determinants of aid donorship. We hypothesize that democratic institutions reduce poor countries' likelihood...

We investigate the relationship between political attitudes and prosociality in a survey of a representative sample of the U.S. population during the first summer of the COVID-19 pandemic. We find that an experimental measure of prosociality correlates positively with adherence to protective...

In the past, the European Union seems to have been able to tame Euroscepticism through regional 'convergence' funding. After the Eastern enlargement of the Union, however, this relationship needs to be put to the test. Not only have the new member states become the main recipients of EU funding,...

Populist parties and actors now govern various countries around the world. Often elected by the public in times of crises and over the perceived failure of ‘the elites’, the question stands as to how populist governments actually perform once elected, especially in times of crisis. Using the...

The paper analyzes one important aspect of the constitutional debate: the allocation of econornie competences between the EU and the mernber states. It takes the theory of fiscal federalism as a starting point for an optimal allocation of economic competences. The main message of the theory is...
