This paper develops a world economy HANK model for the Euro Area (EA) Core and Periphery, which captures key features of EA cross‐ and within‐country heterogeneity, to study debt target reforms. We show that fiscal consolidation under the current EA institutional arrangements is quite costly...

This paper assesses the causal relationship between central bank interest rate, inflation and GDP growth in Central African countries using a new leading-lagging method over the period 1990-2019. The results show a short-term relationship between the three variables, with strong evidence of...

The financial situation of households differs substantially across countries, but the implications of this heterogeneity are still vastly understudied. We examine the implications of this asymmetry for optimal monetary policy in a currency union. We build a two-country monetary union model with...

The 1955-56 macroeconomic crisis is a central event in modern Irish history. Yet, despite this centrality, its causes are not clearly understood. In 1955-6, Ireland, which had previously followed British interest rates in lockstep as part of its fixed exchange with the latter, briefly...

The distributional and disruptive effects of energy supply shocks are potentially large. We study the effectiveness of alternative fiscal responses in a two-country HANK model calibrated to the euro area. Subsidies can stabilize the domestic economy, but they are fiscally costly and generate...

Using newly collected discount rate data for six Swiss cities, we find no evidence of increasing integration during a 30-year period of lightly regulated free banking. We attribute this to two structural issues: banks had incentives to protect their local monopolies, and the inherent instability...

Southern African Development Community (SADC) and East African Community (EAC) countries are exploring the feasibility of establishing a monetary union. This study assesses the economic integration in the two blocs, using the interest rate pass‑through mechanism to determine the convergence of...

How does a monetary union alter the impact of business cycle shocks at the household level? We develop a Heterogeneous Agent New Keynesian model of two countries (HANK2) and show in closed form that a monetary union shifts the adjustment to a shock horizontally - across countries - within the...

In the 24 years since its introduction, the euro has experienced a financial crisis, a government debt crisis, a global pandemic, and an energy crisis-and survived. Using a model focusing on households, this Weekly Report shows that the monetary union’s stability is rooted in the fact that the...

The distributional and disruptive effects of energy supply shocks are potentially large. We study the effectiveness of alternative fiscal responses in a two-country HANK model that we calibrate to the euro area. Energy subsidies can stabilize the domestic economy, but are fiscally costly and...

How is the price level determined in a monetary union when the common monetary policy pegs the nominal interest rate? How are the price levels in the member countries determined? We extend the fiscal theory of the price level to the case of a heterogenous monetary union. Price level determinacy...

We study how monetary policy affects local market competition in a union of countries experiencing different economic conditions: the euro area. We find that when monetary conditions tighten (loosen), from the point of view of an individual economy, market concentration increases (declines)....

Differences in labour market institutions and regulations between countries of the monetary union can cause divergent responses even to a common shock. We augment a multi-country model of the euro area with search and matching framework that differs across Ricardian and hand-to-mouth households....

The distributional and disruptive effects of energy supply shocks are potentially large. We study the effectiveness of alternative fiscal responses in a two-country HANK model calibrated to the euro area. Subsidies can stabilize the domestic economy, but they are fiscally costly and generate...

This paper studies the impact of real convergence in the EU countries on inflation synchronization between these countries and the Eurozone. Inflation co-movement between the Eurozone and the EU countries serves as an important measure of the adequacy of the single monetary policy for both...

This article is focusing on the economic literature attempting to solve the problem of the impossible trilemmas of the euro area, by reconciling the relations between the three essential pillars - supranational monetary independence, national fiscal independence and the no bail-out clause...

This Selected Issues paper analyzes domestic revenue mobilization (DRM) in the West African Economic and Monetary Union (WAEMU). DRM is critical for financing economic and social development and ensuring debt sustainability in WAEMU, especially in light of rising interest, high security...

This paper presents IMF staff report on common policies for member countries of West African Economic and Monetary Union (WAEMU). Economic growth continues to be strong in the WAEMU. Inflation has fallen back to its target range, and recent improvements in regional external imbalances are...

This Selected Issues paper examines the impact of the energy transition (ET) and strategies to achieve it in the Easter Caribbean Currency Union (ECCU). Reducing energy dependence in the ECCU entails improving energy efficiency and shifting from fossil fuels to renewable energy (RE). This ET is...

This paper presents a detailed review report for the 2025 Discussion on Common Policies of Member Countries of the Easter Caribbean Currency Union (ECCU). The currency union has provided a strong anchor for macroeconomic stability. The ECCU has achieved a strong rebound from successive adverse...

Since mid-2021, the euro-area economy has gone through several shocks, leading to the highest inflation since the creation of the European Monetary Union. A forceful and persistent response from the European Central Bank, grounded in the monetary policy framework it agreed in 2021 ahead of the...

We investigate how the composition of expenditure shapes the transmission of monetary policy in a currency union. European Monetary Union data reveal three facts: (1) higher inequality countries have larger service expenditure shares; (2) monetary policy has a weaker output impact in these...

Based on original archival research, interviews, media sources and wide ranging academic literature, this study focuses on the European Parliament's leading and agenda-setting role in the process of European monetary integration. Important initiatives included the 1962 Van Campen Report on the...
