Step by Step ‒ A Quarterly Evaluation of EU Commission's GDP Forecasts

No. 3,

Abstract
The European Commission’s growth forecasts play a crucial role in shaping policies and provide a benchmark for many (national) forecasters. The annual forecasts are built on quarterly estimates, which do not receive much attention and are hardly known. Therefore, this paper provides a comprehensive analysis of multi-period ahead quarterly GDP growth forecasts for the European Union (EU), euro area, and several EU member states with respect to first-release and current-release data. Forecast revisions and forecast errors are analyzed, and the results show that the forecasts are not systematically biased. However, GDP forecasts for several member states tend to be overestimated at short-time horizons. Furthermore, the final forecast revision in the current quarter is generally downward biased for almost all countries. Overall, the differences in mean forecast errors are minor when using real-time data or pseudo-real-time data and these differences do not significantly impact the overall assessment of the forecasts’ quality. Additionally, the forecast performance varies across countries, with smaller countries and Central and Eastern European countries (CEECs) experiencing larger forecast errors. The paper provides evidence that there is still potential for improvement in forecasting techniques both for nowcasts but also forecasts up to eight quarters ahead. In the latter case, the performance of the mean forecast tends to be superior for many countries.

The Distribution of National Income in Germany, 1992-2019
Stefan Bach, Charlotte Bartels, Theresa Neef
IWH Discussion Papers,
No. 25,
2024
Abstract
This paper analyzes the distribution and composition of pre-tax national income in Germany since 1992, combining personal income tax returns, household survey data, and national accounts. Inequality rose from the 1990s to the late 2000s due to falling labor incomes among the bottom 50% and rising incomes in the top 10%. This trend reversed after 2007 as labor incomes across the bottom 90% increased. The top 1% income share, dominated by business income, remained relatively stable between 1992 and 2019. A large share of Germany’s top 1% earners are non-corporate business owners in labor-intensive professions. At least half of the business owners in P99-99.9 and a quarter in the top 0.1% operate firms in professional services – a pattern mirroring the United States. From 1992 to 2019, Germany’s top 0.1% income concentration exceeded France’s and matched U.S. levels until the late 2000s.

Regional Industrial Effects in Germany from a Potential Gas Deficit
Robert Lehmann, Christoph Schult
German Economic Review,
No. 3,
2024
Abstract
We estimate potential regional industrial effects in case of a threatening gas deficit. For Germany, the reduction leads to a potential decrease in industrial value added by 1.6 %. The heterogeneity across German states is remarkable, ranging from 2.2 % for Rhineland-Palatinate to 0.7 % for Hamburg. We emphasize the need for regional input-output tables to conduct economic analysis on a sub-national level, particularly when regional industrial structures are heterogeneous. The approximation with national figures can lead to results that differ both in magnitude and relative regional exposure. Our findings highlight that more accurate policy guidance can be achieved by improving the regional database.

Drehtüren in den Vorstandsetagen der Finanzaufsicht: Sind Banker oder Bürokraten die besseren Aufseher?
Michael Koetter, Noel Nietzold
Wirtschaft im Wandel,
No. 2,
2024
Abstract
Der „umgekehrte Drehtüreffekt“ beschreibt das Phänomen, wenn ehemalige Bankerinnen und Banker Vorstandspositionen in nationalen Aufsichtsbehörden (National Supervisory Agency, NSA) bekleiden. Ein neu erhobener Datensatz zeigt, dass etwa ein Drittel der Vorstandsmitglieder in europäischen NSA vorher in der Finanzindustrie tätig war. Die Bestellung ehemaliger Banker in NSA-Vorstände geht mit positiven Börsenreaktionen einher, was auf eine „Näheprämie“ in der Bewertung beaufsichtigter Banken hindeutet. Im Gegensatz dazu ruft die Berufung von Bürokraten ohne praktische Vorkenntnisse in der Bankenwelt negative Börsenreaktionen hervor. Bis zur Einführung des Einheitlichen Aufsichtsmechanismus (Single Supervisory Mechanism, SSM) in Europa korreliert die Präsenz ehemaliger Banker in NSA-Vorständen mit einer geringeren regulatorischen Kapitalquote, was auf einen nachsichtigeren Aufsichtsstil schließen lässt.

Chinese mass imports strengthen extreme parties
Globalisation has led to an increase in votes for the political fringes in Europe. A study by the Halle Institute for Economic Research (IWH) is the first to show the long-term consequences of increased Chinese imports in European regions: Far-right and populist parties in particular have benefited from the so-called China shock in national elections.
