Productivity, Place, and Plants

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.

Risk in the banking sector: four out of ten top supervisors come from the financial industry
Europe's banks realise excess returns on the stock market when their alumni join the boards of national supervisory authorities. A study by the Halle Institute for Economic Research (IWH) shows that this happens more frequently than previously recognised. The findings indicate a risk to financial stability and call for a more merit-based, transparent appointment of senior regulators.

Does Information about Inequality and Discrimination in Early Child Care Affect Policy Preferences?
Henning Hermes, Philipp Lergetporer, Fabian Mierisch, Guido Schwerdt, Simon Wiederhold
IWH Discussion Papers,
No. 2,
2024
Abstract
We investigate public preferences for equity-enhancing policies in access to early child care, using a survey experiment with a representative sample of the German population (n ≈ 4, 800). We observe strong misperceptions about migrant-native inequalities in early child care that vary by respondents’ age and right-wing voting preferences. Randomly providing information about the actual extent of inequalities has a nuanced impact on the support for equity-enhancing policy reforms: it increases support for respondents who initially underestimated these inequalities, and tends to decrease support for those who initially overestimated them. This asymmetric effect leads to a more consensual policy view, substantially decreasing the polarization in policy support between under- and overestimators. Our results suggest that correcting misperceptions can align public policy preferences, potentially leading to less polarized debates about how to address inequalities and discrimination.

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 downturn in 2023 is milder in East Germany than in Germany as a whole – Implications of the Joint Economic Forecast Autumn 2023 and of Länder data from recent publications of the Statistical Offices
The German economy has been in a downturn for more than a year. In East Germany, however, the economy has been somewhat stronger in the past four quarters: According to the Halle Institute for Economic Research (IWH), East German gross domestic product (GDP) is expected to increase by 0.5% in 2023, while production in Germany as a whole will fall by 0.6%. Next year, expansion rates of 1.3% are forecast in both the east and the west. For 2025, East German gross domestic product is expected to grow by 1.2%, which is slightly slower than in Germany as a whole (1.5%).

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).

R&D Tax Credits and the Acquisition of Startups
William McShane, Merih Sevilir
IWH Discussion Papers,
No. 15,
2023
Abstract
We propose a novel mechanism through which established firms contribute to the startup ecosystem: the allocation of R&D tax credits to startups via the M&A channel. We show that when established firms become eligible for R&D tax credits, they increase their R&D and M&A activity. In particular, they acquire more venture capital (VC)-backed startups, but not non-VC-backed firms. Moreover, the impact of R&D tax credits on firms’ R&D is increasing with their acquisition of VC-backed startups. The results suggest that established firms respond to R&D tax credits by acquiring startups rather than solely focusing on increasing their R&D intensity in-house. We also highlight evidence that startups do not appear to benefit from R&D tax credits directly, perhaps because they typically lack the taxable income necessary to directly benefit from the tax credits. In this context, established firms can play an intermediary role by acquiring startups and reallocating R&D tax credits, effectively relaxing the financial constraints faced by startups.

Males Should Mail? Gender Discrimination in Access to Childcare
Henning Hermes, Philipp Lergetporer, Fabian Mierisch, Frauke Peter, Simon Wiederhold
American Economic Association Papers and Proceedings,
May
2023
Abstract
This study investigates discrimination against women when searching and applying for childcare in a nationwide field experiment. We send emails from fictitious parents to 9,313 childcare centers in Germany inquiring about access to childcare. We randomize whether the email is sent by the child's mother or father. Our results show that women receive shorter and less positive responses than men. The probability of receiving a response does not differ by gender, highlighting the importance of going beyond response rates to detect discrimination. We provide suggestive evidence that regional differences in gender discrimination are related to gender norms.

East German economy has come through energy crisis well so far – Implications of the Joint Economic Forecast Spring 2023 and new data for the East German economy
In 2022, the East German economy expanded by 3.0%, significantly stronger than the economy in West Germany (1.5%). The background is a more robust development of labour and retirement incomes. For 2023, the Halle Institute for Economic Research (IWH) forecasts a higher GDP growth rate of 1% in East Germany than in Germany as a whole (0.3%). The unemployment rate is expected to stagnate, with 6.8% in 2023 and 6.7% in the following year.
