Abstract
This study examines how antitrust law adoptions affect horizontal merger and acquisition (M&A) outcomes. Using the staggered introduction of competition laws in 20 countries, we find antitrust regulation decreases acquirers’ five-day cumulative abnormal returns surrounding horizontal merger announcements. A decrease in deal value, target book assets, and industry peers' announcement returns are consistent with the market power hypothesis. Exploiting antitrust law adoptions addresses a downward bias to an estimated effect of antitrust enforcement (Baker (2003)). The potential bias from heterogeneous treatment effects does not nullify our results. Overall, antitrust policies seem to deter post-merger monopolistic gains, potentially improving customer welfare.

Productivity, Place, and Plants
Benjamin Schoefer, Oren Ziv
Review of Economics and Statistics,
forthcoming
Abstract
Why do cities differ so much in productivity? A long literature has sought out systematic sources, such as inherent productivity advantages, market access, agglomeration forces, or sorting. We document that up to three quarters of the measured regional productivity dispersion is spurious, reflecting the “luck of the draw” of finite counts of idiosyncratically heterogeneous plants that happen to operate in a given location. The patterns are even more pronounced for new plants, hold for alternative productivity measures, and broadly extend to European countries. This large role for individual plants suggests a smaller role for places in driving regional differences.

Joint Economic Forecast 1/2024: Headwinds from Germany and abroad: institutes revise forecast significantly downwards
According to Germany’s five leading economic research institutes, the country’s economy shows cyclical and structural weaknesses. In their spring report, they revised their GDP forecast for the current year significantly downward to 0.1%. In the recent fall report, the figure was still 1.3%. Expectations for the coming year are almost unchanged at 1.4% (previously 1.5%). However, the level of economic activity will then be over 30 billion euros lower due to the current weak phase.

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.

Deutschland in der Stagnation festgefahren – privater Konsum weiter unter dem Niveau
von vor der Pandemie
Konjunktur aktuell,
No. 1,
2024
Abstract
Zu Beginn des Jahres 2024 zeigen Stimmungsindikatoren etwas aufgehellte Aussichten für die internationale Konjunktur. In Europa dürfte die Dynamik allerdings recht schwach bleiben. Deutschland befindet sich in einer lang anhaltenden Stagnation, die sich bis zum Sommer fortsetzen wird. Für die Zeit danach ist mit einem leichten Anziehen der Konjunktur zu rechnen. Das Bruttoinlandsprodukt dürfte im Jahr 2024 um lediglich 0,2% expandieren, für 2025 prognostiziert das IWH einen Zuwachs um 1,5%.

Trade Shocks, Labour Markets and Migration in the First Globalisation
Richard Bräuer, Felix Kersting
Economic Journal,
No. 657,
2024
Abstract
This paper studies the economic and political effects of a large trade shock in agriculture—the grain invasion from the Americas—in Prussia during the first globalisation (1870–913). We show that this shock led to a decline in the employment rate and overall income. However, we do not observe declining per capita income and political polarisation, which we explain by a strong migration response. Our results suggest that the negative and persistent effects of trade shocks we see today are not a universal feature of globalisation, but depend on labour mobility. For our analysis, we digitise data from Prussian industrial and agricultural censuses on the county level and combine them with national trade data at the product level. We exploit the cross-regional variation in cultivated crops within Prussia and instrument with Italian and United States trade data to isolate exogenous variation.

The Aggregate Effects of the Decline of Disruptive Innovation
Richard Bräuer
IWH Discussion Papers,
No. 22,
2023
Abstract
This paper proposes a model that explains both recently documented facts about the decline of disruptive innovation and the decline in productivity growth as the result of large firms trying to monopolize technologies by poaching inventors from disruptive activities. To come to this conclusion, the paper builds an endogenous growth model with inventor labor markets on which firms can interact strategically. To inform this model, I perform an event study of the effect of disruptive inventions on their technology fields using PATSTAT (1980-2010). I document that technology classes without disruption slowly trend towards incrementalism and that after a disruption, more patents get registered and research becomes less incremental.

Exports and private consumption weak ‒ Germany is waiting for an economic upturn
In the winter of 2023/2024, the German economy is still in a downturn. Parts of industry have lost competitiveness, real incomes have fallen in 2023 due to inflation, and there is uncertainty about the course of fiscal policy. However, rising real incomes and a slight increase in exports should cause a pickup from spring onwards. The Halle Institute for Economic Research (IWH) expects gross domestic product (GDP) to fall by 0.3% in 2023 and to expand by 0.5% in 2024 (East Germany: +0.5% and +0.7%). In September, the IWH forecast had assumed a decline of 0.5% for Germany in 2023 and expected growth of 0.9% for the coming year.

Labor Market Power and Between-Firm Wage (In)Equality
Matthias Mertens
International Journal of Industrial Organization,
December
2023
Abstract
I study how labor market power affects firm wage differences using German manufacturing sector firm-level data (1995-2016). In past decades, labor market power increasingly moderated rising between-firm wage differences. This is because high-paying firms possess high and increasing labor market power and pay wages below competitive levels, whereas low-wage firms pay competitive or even above competitive wages. Over time, large, high-wage, high-productivity firms generate increasingly large labor market rents while charging comparably low product markups. This provides novel insights on why such top firms are profitable and successful. Using micro-aggregated data covering most economic sectors, I validate key results for multiple European countries.

Joint Economic Forecast 2/2023: Purchasing power returns ‒ political uncertainty high
According to the Joint Economic Forecast, Germany's gross domestic product declines by 0.6% in 2023. This is a strong downward revision of 0.9 percentage points from the forecast made in spring 2023. "The most important reason for this revision is that industry and private consumption are recovering more slowly than we expected in spring," says Oliver Holtemöller, Vice President and Head of the Macroeconomics Department at the Halle Institute for Economic Research (IWH).
