Evidence-based Support for Adaptation Policies in Emerging Economies
Maximilian Banning, Anett Großmann, Katja Heinisch, Frank Hohmann, Christian Lutz, Christoph Schult
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.

Minimum Wages, Productivity, and Reallocation
Mirja Hälbig, Matthias Mertens, Steffen Müller
IZA Discussion Paper,
No. 16160,
2023
Abstract
We study the productivity effect of the German national minimum wage by applying administrative firm data. At the firm level, we confirm positive effects on wages and negative employment effects and document higher productivity even net of output price increases. We find higher wages but no employment effects at the level of aggregate industry × region cells. The minimum wage increased aggregate productivity in manufacturing. We do not find that employment reallocation across firms contributed to these aggregate productivity gains, nor do we find improvements in allocative efficiency. Instead, the productivity gains from the minimum wage result from within-firm productivity improvements only.

Business Cycle Characteristics of Mediterranean Economies: a Secular Trend and Cycle Dynamics Perspective
Anna Solms, Bernd Süssmuth
International Economics and Economic Policy,
October
2022
Abstract
This study analyzes business cycle characteristics for all 20 major contemporaneous economies bordering the Mediterranean Sea based on annual real gross domestic product series for the period from 1960 to 2019. The region we investigate corresponds to the Mare Internum region of the Imperial Roman Empire during the Nerva-Antonine and early Severan dynasty, i.e., at the time of the maximum extent of the Roman Empire around 100 to 200 CE. The covered area encircles the Mediterranean, including economies now belonging to the European Union as well as acceding countries, Turkey, and the Middle East and North African economies. Using a components-deviation-cycle approach, we assess level trends and relative volatility of output. We also quantify the contribution of various factors to the business cycle variability within a region. We find cyclic commonalities and idiosyncrasies are related to ancient and colonial history and to contemporaneous trade relationships. Caliphate and Ottoman Empire membership as well as colonial rule in the twentieth century and contemporary Muslim share of population are the most promising predictors of business cycle commonalities in the region.

The Cleansing Effect of Banking Crises
Reint E. Gropp, Steven Ongena, Jörg Rocholl, Vahid Saadi
Economic Inquiry,
No. 3,
2022
Abstract
We assess the cleansing effects of the 2008–2009 financial crisis. U.S. regions with higher levels of supervisory forbearance on distressed banks see less restructuring in the real sector: fewer establishments, firms, and jobs are lost when more distressed banks remain in business. In these regions, the banking sector has been less healthy for several years after the crisis. Regions with less forbearance experience higher productivity growth after the crisis with more firm entries, job creation, and employment, wages, patents, and output growth. Forbearance is greater for state-chartered banks and in regions with weaker banking competition and more independent banks.

Projektion der wirtschaftlichen Entwicklung in den Bundesländern 2022 bis 2060
Oliver Holtemöller
IWH Technical Reports,
No. 1,
2022
Abstract
Die Entwicklung der wirtschaftlichen Leistungsfähigkeit in den Bundesländern wird in den kommenden Jahren vor allem durch das langfristige Produktivitätswachstum und die Verschiebung der Altersstruktur gekennzeichnet sein. Der Altenquotient, der das zahlenmäßige Verhältnis von Personen über 64 Jahren zu den Personen zwischen 15 und 64 Jahren abbildet, wird gemäß Bevölkerungsvorausberechnungen der Statistischen Ämter von gut 30% auf über 50% bis zum Jahr 2060 ansteigen. Allerdings unterscheiden sich Ausgangslage bei der Produktivität und Altersstruktur in den Bundesländern teilweise erheblich, sodass sich auch das Bruttoinlandsprodukt je Einwohner in den kommenden Jahren regional unterschiedlich entwickeln wird.

The Crisis is Gradually Being Overcome

Wirtschaftsdienst,
No. 10,
2021
Abstract
Die führenden Wirtschaftsforschungsinstitute senken ihre BIP-Wachstumsprognose für 2021 von 3,7 % auf 2,4 %. Dafür ist insbesondere die schwächelnde Industrieproduktion verantwortlich, die unter Lieferengpässen leidet. Die internationale Konjunktur erholt sich zwar von den Verwerfungen der Corona-Pandemie, aber nur langsam, da die Impffortschritte regional unterschiedlich sind. Die Verbraucherpreise haben sich 2021 stark erhöht.
