Global economy under the spell of the coronavirus epidemic
The epidemic is obstructing the economic recovery in Germany. Foreign demand is falling, private households forgo domestic consumption if it comes with infection risk, and investments are postponed. Assuming that the spread of the disease can be contained in short time, GDP growth in 2020 is expected to be 0.6% according to IWH spring economic forecast. Growth in East Germany is expected to be 0.9% and thus higher than in West Germany. If the number of new infections cannot be decreased in short time, we expect a recession in Germany.

Downturn in Germany continues
Trade disputes are causing international trade in goods to decline this year. The manufacturing industry in Germany is particularly affected by this. However, a robust labour market is supporting the economy. According to IWH autumn economic forecast, German gross domestic product (GDP) will increase by 0.5% in 2019. At 1%, output growth in East Germany is likely to be significantly higher than in West Germany.

Study: How financial crises lower life satisfaction and how to prevent this
Financial crises not only result in severe disruptions to the economic system, they also affect people’s life satisfaction. A new study by Martin Luther University Halle-Wittenberg (MLU) and the Halle Institute for Economic Research (IWH) shows that weaker members of society are more affected by increased uncertainty during crisis times, even if they may not be speculating on the stock market themselves. This could potentially also lower their propensity to consume, thereby intensifying the impact of a financial crisis. The study was recently published in “The B.E. Journal of Economic Analysis & Policy”.

Vertical Grants and Local Public Efficiency
Ivo Bischoff, Peter Bönisch, Peter Haug, Annette Illy
Public Finance Review,
No. 3,
2019
Abstract
The existing empirical literature on the impact of vertical grants on local public-sector efficiency yields mixed results. Given the fact that vertical financial equalization systems often reduce differences in fiscal capacity, we argue that empirical studies based on cross-sectional data may yield a positive relationship between grants and efficiency of public service production even when the underlying causal effect is not. We provide a simple illustrative theoretical model to show the logic of our argument and illustrate its relevance by an empirical case study for the German state of Saxony-Anhalt. We show that our main argument of an inference-disturbing effect applies to those existing studies that are more optimistic about the impact of vertical grants. Finally, we argue that it may disturb the inference drawn from studies in a number of other countries where vertical grants—intended or not—concentrate in fiscally weak municipalities.

Bank profitability increases after eliminating consolidation barriers
When two banks merge because political consolidation barriers are abolished, the combined entity is considerably more profitable and useful to the real economy. This is the headline result of an analysis of compulsory savings banks mergers carried out by the Halle Institute for Economic Research (IWH). The study yields important insights for the German and the European banking market.

Identifying Cooperation for Innovation – A Comparison of Data Sources
Michael Fritsch, Matthias Piontek, Mirko Titze
Abstract
The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidised collaborative Research and Development projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers. The key role of universities that connect many regional actors is identified in all three types of data.

IWH Mid-term Projections: The German Economy and Public Finances 2018 to 2025
In 2018 the general government overall balance is likely to be in surplus by almost 60 billion euros. In the medium term, however, demographic conditions will deteriorate, as will public finances. The financial position of the German state will nevertheless remain stable until 2025, unless major negative shocks occur. “But even if interest rates rose significantly or foreign demand declined markedly, only moderate deficits would arise”, says Oliver Holtemöller, head of the Department of Macroeconomics and vice president at Halle Institute for Economic Research (IWH). However, given the expected reduction of the surplus under existing legislation, there is no room for further increases in spending.

Zu den rentenpolitischen Plänen im Koalitionsvertrag 2018 von CDU, CSU und SPD: Konsequenzen, Finanzierungsoptionen und Reformbedarf
Oliver Holtemöller, Christoph Schult, Götz Zeddies
Zeitschrift für Wirtschaftspolitik,
No. 3,
2018
Abstract
In the coalition agreement from February 7, 2018, the new German federal government drafts its public pension policy, which has to be evaluated against the background of demographic dynamics in Germany. In this paper, the consequences of public pensions related policy measures for the German public pension insurance are illustrated using a simulation model. In the long run, the intended extensions of benefits would lead to an increase in the contribution rate to the German public pension insurance of about two and a half percentage points. Referring to pension systems of other countries, we discuss measures in order to limit this increase in the contribution rate.

Kosten der Maßnahmen aus dem „Entwurf eines Gesetzes über Leistungsverbesserungen und Stabilisierung in der gesetzlichen Rentenversicherung“
Oliver Holtemöller, Götz Zeddies
IWH Online,
No. 3,
2018
Abstract
Der Referentenentwurf des Gesetzes über Leistungsverbesserungen und Stabilisierung in der gesetzlichen Rentenversicherung sieht folgende Leistungsausweitungen in der gesetzlichen Rentenversicherung vor: Fixierung des Rentenniveaus bei 48% und der Haltelinie für den Beitragssatz bei 20%, Aufstockung der Mütterrente, Verbesserungen für Erwerbsgeminderte und Ausweitung der Gleitzone (so genannte „Midijobs“).
Diese Maßnahmen werden vor allem langfristig erhebliche Auswirkungen auf die Ausgaben der Rentenversicherung haben; gleichzeitig wird die Anzahl der Beitragszahler aufgrund der Alterung der Bevölkerung abnehmen. Das heißt, selbst ohne die neuen Leistungsausweitungen stiegen die Abgaben (Beiträge und Steuern) zur Finanzierung der Rentenversicherung langfristig deutlich an.
Berechnungen mit dem Rentensimulationsmodell des IWH zeigen, dass die effektive Abgabenlast (Rentenversicherungsbeitrag plus Steuerzuschüsse) in Relation zum Lohn bis zum Jahr 2050 ohne die neuen Leistungsausweitungen um acht und mit um weitere drei Prozentpunkte zunehmen dürfte. Wenn der Beitragssatz bei 20% konstant gehalten werden soll, müssten etwa die Einkommensteuer oder die Umsatzsteuer entsprechend kräftig erhöht werden.

Joint Economic Forecast Spring 2018: Germany’s Economic Experts Raise Forecast Slightly
Berlin, 19 April – Germany’s leading economic experts raised their forecasts for 2018 and 2019 slightly in their Spring Joint Economic Forecast released on Thursday in Berlin. They now expect economic growth of 2.2 percent for this year and 2.0 percent for 2019, versus 2.0 percent and 1.8 percent respectively in their autumn forecast. “The German economy is still booming, but the air is getting thinner as unused capacities are shrinking“, notes Timo Wollmershaeuser, ifo Head of Economic Forecasting. Commenting on the new German government’s economic policy, he adds: “It is precisely when the government’s coffers are full that fiscal policy should reflect the implications of its actions for overall economic stability and the sustainability of public finances. The extension of statutory pension benefits outlined in the coalition agreement runs counter to the idea of sustainability.”
