Abstract
Das Produktionspotenzial der deutschen Wirtschaft wächst mittelfristig (2023 bis 2029) mit einer jahresdurchschnittlichen Rate von 0,3% und damit deutlich schwächer als in den Jahren zuvor. Dies ist auf eine ungünstigere Entwicklung aller drei Faktoren (Arbeitsvolumen, Kapitalstock, totale Faktorproduktivität) zurückzuführen. Das potenzielle Wachstum wird insbesondere durch den Rückgang der durchschnittlichen Arbeitszeit gedämpft.

Konjunktur aktuell: Frostige Aussichten für die deutsche Wirtschaft
Konjunktur aktuell,
No. 4,
2024
Abstract
Zur Jahreswende dürfte die weltweite Produktion weiterhin in etwa so schnell wie in der Dekade vor der Pandemie expandieren. Die Konjunktur im Euroraum ist nur verhalten, und die Stagnation der deutschen Wirtschaft setzt sich fort. Die Industrie verliert an internationaler Wettbewerbsfähigkeit. Unternehmen und Verbraucher halten sich aufgrund unklarer wirtschaftspolitischer Aussichten mit ihren Ausgaben zurück. Das Bruttoinlandsprodukt dürfte im Jahr 2024 um 0,2% sinken und im Jahr 2025 um 0,4% expandieren.

Moderate economic growth in the world – German economy continues to stagnate
Production in Germany has been stagnating for two years and is roughly the same level as shortly before the outbreak of the pandemic. Investment of firms is particularly weak. An important reason for fewer investments is the sluggish export business. Private households are also holding back on consumption, mainly due to concerns about the longer-term economic outlook. According to the autumn forecast of the Halle Institute for Economic Research (IWH), gross domestic product in Germany is likely to stagnate in 2024 and to increase by 1.0% in 2025 as capacity utilisation normalises. In June, the IWH forecast had still assumed a growth of 0.3% in 2024 and of 1.5% in 2025. In East Germany, gross domestic product will increase by 0.3% this year and by 0.9% in 2025.

Optimal Monetary Policy in a Two-sector Environmental DSGE Model
Oliver Holtemöller, Alessandro Sardone
IWH Discussion Papers,
No. 18,
2024
Abstract
In this paper, we discuss how environmental damage and emission reduction policies affect the conduct of monetary policy in a two-sector (clean and dirty) dynamic stochastic general equilibrium model. In particular, we examine the optimal response of the interest rate to changes in sectoral inflation due to standard supply shocks, conditional on a given environmental policy. We then compare the performance of a nonstandard monetary rule with sectoral inflation targets to that of a standard Taylor rule. Our main results are as follows: first, the optimal monetary policy is affected by the existence of environmental policy (carbon taxation), as this introduces a distortion in the relative price level between the clean and dirty sectors. Second, compared with a standard Taylor rule targeting aggregate inflation, a monetary policy rule with asymmetric responses to sector-specific inflation allows for reduced volatility in the inflation gap, output gap, and emissions. Third, a nonstandard monetary policy rule allows for a higher level of welfare, so the two goals of welfare maximization and emission minimization can be aligned.

German economy still on the defensive – but first signs of an end to the downturn
In the first half of 2024, signs of an economic recovery are increasing. Production, however, is likely to expand only modestly during summer. From the autumn, the recovery is likely to pick up speed with higher real incomes and a modest increase in exports. In its summer forecast, the Halle Institute for Economic Research (IWH) expects gross domestic product to expand by 0.3% in 2024 and by 1.5% in 2025 (East Germany: 0.6% and 1.4%). In March, the IWH forecast had assumed a growth of 0.2% in 2024 and of 1.5% in 2025.

Gesamtwirtschaftliche Effekte von Fußball-Meisterschaften: Die WM 2006 und die EM 2024 in Deutschland
Andrej Drygalla, Katja Heinisch, Oliver Holtemöller
Konjunktur aktuell,
No. 2,
2024
Abstract
Fußball-Welt- und Europameisterschaften sind große gesellschaftliche Ereignisse. Gesamtwirtschaftlich fallen sie in großen Volkswirtschaften mit bestehender Sport- und Verkehrsinfrastruktur und vorhandenen Kapazitäten im Gastgewerbe allerdings kaum ins Gewicht. In diesem Beitrag werden Studien zu den ökonomischen Effekten von Sportgroßveranstaltungen zusammengefasst, die wirtschaftlichen Effekte der Fußball-Weltmeisterschaft 2006 in Deutschland untersucht und daraus die zu erwartenden gesamtwirtschaftlichen Effekte der Fußball-Europameisterschaft 2024 in Deutschland abgeleitet. Die Bauaktivität in den Spielorten nimmt im Vorfeld der Meisterschaften zu; Effekte auf das Gastgewerbe gibt es hingegen kaum – vermutlich vor allem aufgrund von Verdrängungseffekten. Insgesamt war die gesamte nominale Bruttowertschöpfung im WM-Jahr 2006 in den Spielorten gut 1% höher als ohne die WM zu erwarten gewesen wäre; in realer Rechnung ist insgesamt kein signifikanter Effekt zu beobachten.

Germany stuck in stagnation ‒ private consumption remains below pre-pandemic levels
Weak consumption and investment in Germany are partly due to inflation-induced losses in real income and declines in energy-intensive production. However, concerns about the competitive strength of the German economy are also weighing on the willingness of private households and companies to spend. In its spring forecast, the Halle Institute for Economic Research (IWH) expects gross domestic product to expand by just 0.2% in 2024, while the forecast for 2025 includes growth of 1.5% (eastern Germany: 0.5% and 1.4%). Last December, the IWH forecast had assumed an increase of 0.5% for Germany in 2024 and of 1.2% for 2025.

Green transition and the debt brake: Implications of additional investment for public finances and private consumption in Germany
The German Climate Protection Act stipulates, among other things, that greenhouse gas emissions in Germany are to be reduced by 65% by 2030 compared to 1990 levels. The green investments required to achieve this target are likely to amount to around 2.5% of gross domestic product each year. According to the medium-term projection of the Halle Institute for Economic Research (IWH), the associated additional government spending on public investment and support measures cannot be financed from projected tax revenues. It is therefore to be expected that the tax burden on households will increase and private consumption will be curbed accordingly, if both the current form of the debt brake and the greenhouse gas reduction targets are maintained.

Macroeconomic Effects from Sovereign Risk vs. Knightian Uncertainty
Ruben Staffa
IWH Discussion Papers,
No. 27,
2023
Abstract
This paper compares macroeconomic effects of Knightian uncertainty and risk using policy shocks for the case of Italy. Drawing on the ambiguity literature, I use changes in the bid-ask spread and mid-price of government bonds as distinct measures for uncertainty and risk. The identification exploits the quasi-pessimistic behavior under ambiguity-aversion and the dealer market structure of government bond markets, where dealers must quote both sides of the market. If uncertainty increases, ambiguity-averse dealers will quasi-pessimistically quote higher ask and lower bid prices – increasing the bid-ask spread. In contrast, a pure change in risk shifts the risk-compensating discount factor which is well approximated by the change in bond mid-prices. I evaluate economic effects of the two measures within an instrumental variable local projection framework. The main findings are threefold. First, the resulting shock time series for uncertainty and risk are uncorrelated with each other at the intraday level, however, upon aggregation to monthly level the measures become correlated. Second, uncertainty is an important driver of economic aggregates. Third, macroeconomic effects of risk and uncertainty are similar, except for the response of prices. While sovereign risk raises inflation, uncertainty suppresses price growth – a result which is in line with increased price rigidity under ambiguity.

The Importance of Credit Demand for Business Cycle Dynamics
Gregor von Schweinitz
IWH Discussion Papers,
No. 21,
2023
Abstract
This paper contributes to a better understanding of the important role that credit demand plays for credit markets and aggregate macroeconomic developments as both a source and transmitter of economic shocks. I am the first to identify a structural credit demand equation together with credit supply, aggregate supply, demand and monetary policy in a Bayesian structural VAR. The model combines informative priors on structural coefficients and multiple external instruments to achieve identification. In order to improve identification of the credit demand shocks, I construct a new granular instrument from regional mortgage origination.
I find that credit demand is quite elastic with respect to contemporaneous macroeconomic conditions, while credit supply is relatively inelastic. I show that credit supply and demand shocks matter for aggregate fluctuations, albeit at different times: credit demand shocks mostly drove the boom prior to the financial crisis, while credit supply shocks were responsible during and after the crisis itself. In an out-of-sample exercise, I find that the Covid pandemic induced a large expansion of credit demand in 2020Q2, which pushed the US economy towards a sustained recovery and helped to avoid a stagflationary scenario in 2022.
