Revival in service sectors, but industrial activity remains weak for the time being
After the recession during winter, the German economy will expand at a moderate pace in the coming quarters and despite higher interest rates, as private consumption will pick up again with slowly declining inflation and increased wage momentum. In its summer forecast, the Halle Institute for Economic Research (IWH) expects gross domestic product to decline by 0.3% in 2023, while growth of 1.7% is forecast for the coming year.

Konjunktur aktuell: Belebung in Dienstleistungsbranchen, aber zunächst weiter schwache Industriekonjunktur
Konjunktur aktuell,
No. 2,
2023
Abstract
Im Sommer 2023 deuten Stimmungsindikatoren auf einen weltweiten Aufschwung in den Dienstleistungsbranchen, die Konjunktur im Verarbeitenden Gewerbe bleibt aber schwach. Hohe Inflation und gestiegene Leitzinsen dämpfen die Konjunktur in den meisten Weltregionen. In Europa belasten auch im langjährigen Vergleich hohe Energiepreise. Insgesamt bleibt die Dynamik der Weltwirtschaft im Jahr 2023 verhalten. Die deutsche Wirtschaft wird in mäßigem Tempo expandieren, denn mit sinkender Inflation und erhöhter Lohndynamik wird der private Konsum wieder zulegen. Das Bruttoinlandsprodukt dürfte 2023 um 0,3% zurückgehen, für das kommende Jahr ist ein Zuwachs von 1,7% prognostiziert. Für 2023 ist mit einer Inflationsrate von 6,1% und für 2024 mit 2,7% zu rechnen.

Long-run Competitive Spillovers of the Credit Crunch
William McShane
IWH Discussion Papers,
No. 10,
2023
Abstract
Competition in the U.S. appears to have declined. One contributing factor may have been heterogeneity in the availability of credit during the financial crisis. I examine the impact of product market peer credit constraints on long-run competitive outcomes and behavior among non-financial firms. I use measures of lender exposure to the financial crisis to create a plausibly exogenous instrument for product market credit availability. I find that credit constraints of product market peers positively predict growth in sales, market share, profitability, and markups. This is consistent with the notion that firms gained at the expense of their credit constrained peers. The relationship is robust to accounting for other sources of inter-firm spillovers, namely credit access of technology network and supply chain peers. Further, I find evidence of strategic investment, i.e. the idea that firms increase investment in response to peer credit constraints to commit to deter entry mobility. This behavior may explain why temporary heterogeneity in the availability of credit appears to have resulted in a persistent redistribution of output across firms.

Intuit QuickBooks Small Business Index: A New Employment Series for the US, Canada, and the UK

IWH Discussion Papers,
No. 9,
2023
Abstract
Small and young businesses are essential for job creation, innovation, and economic growth. Even most of the superstar firms start their business life small and then grow over time. Small firms have less internal resources, which makes them more fragile and sensitive to macroeconomic conditions. This suggests the need for frequent and real-time monitoring of the small business sector’s health. Previously this was difficult due to a lack of appropriate data. This paper fills this important gap by developing a new Intuit QuickBooks Small Business Index that focuses on the smallest of small businesses with at most 9 workers in the US and the UK and at most 19 workers in Canada. The Index aggregates a sample of anonymous Quick- Books Online Payroll subscriber data (QBO Payroll sample) from 333,000 businesses in the US, 66,000 in Canada, and 25,000 in the UK. After comparing the QBO Payroll sample data to the official statistics, we remove the seasonal components and use a Flexible Least Squares method to calibrate the QBO Payroll sample data against official statistics. Finally, we use the estimated model and the QBO Payroll sample data to generate a near real-time index of economic activity. We show that the estimated model performs well both in-sample and out-of-sample. Additionally, we use this analysis for different regions and industries. Keywords:

Evidence-based Support for Adaptation Policies in Emerging Economies

IWH Studies,
No. 2,
2023
Abstract
In recent years, the impacts of climate change become increasingly evident, both in magnitude and frequency. The design and implementation of adequate climate adaptation policies play an important role in the macroeconomic policy discourse to assess the impact of climate change on regional and sectoral economic growth. We propose different modelling approaches to quantify the socio-economic impacts of climate change and design specific adaptations in three emerging market economies (Kazakhstan, Georgia and Vietnam) which belong to the areas that are heavily exposed to climate change. A Dynamic General Equilibrium (DGE) model has been used for Vietnam and economy-energy-emission (E3) models for the other two countries. Our modelling results show how different climate hazards impact the economy up to the year 2050. Adaptation measures in particular in the agricultural sector have positive implications for the gross domestic product (GDP). However, some adaptation measures can even increase greenhouse gas emissions. In addition, the focus on GDP as the main indicator to evaluate policy measures can produce welfare-reducing policy decisions.

European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Journal of the European Economic Association,
No. 2,
2023
Abstract
This paper derives a European Herfindahl–Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity toward large and concentrated industries. Over the same period, productivity gains from an increasing allocative efficiency of the European market accounted for 50% of European productivity growth while markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

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.

Stubborn Core Inflation – Time for Supply Side Policies
The leading economic research institutes have raised their forecast for growth in German economic output in the current year to 0.3%. In the fall, they were still expecting a decline of 0.4%. “The economic setback in the winter half-year 2022/2023 is likely to have been less severe than feared in the fall. The main reason for this is a smaller loss of purchasing power as a result of a significant drop in energy prices,” says Timo Wollmershäuser, Head of Forecasts at ifo. Nevertheless, the rate of inflation will fall only slowly from 6.9% last year to 6.0% this year.
