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.

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.

Subventionswettbewerb: Subventionen für Halbleiter?

Abstract
Hochtechnologien gelten als die Branchen der Zukunft. Europa will hier nicht den Anschluss verlieren. Auch gegen Lieferengpässe und Produktionsengpässe durch gestörte Lieferketten will sich Europa besser wappnen. Mit dem „European Chips Act“ will die Europäische Kommission gemeinsam mit den Mitgliedstaaten mehr als 40 Mrd. Euro ausgeben, um die europäische Halbleiter-Produktion von gegenwärtig 10 % auf dann 20 % der globalen Produktion zu steigern. Halbleiter sind nicht nur in Gebrauchsgegenständen wie Handys, Laptops und Autos, sie sind auch unverzichtbar, wenn die grüne und digitale Wende gelingen soll. Photovoltaikanlagen, nachhaltige Produktion und E-Mobilität – all das braucht Computerchips. Der „European Chips Act“ ist daher die Antwort der EU auf den „Chips-Act“ der USA, der mehr als 50 Mrd. US-$ für Halbleiter vorsieht, um die Produktion zu sichern, zu modernisieren und auszubauen.

Gas storages full – economic outlook less gloomy
The severe slump in the German economy expected last fall has not materialised because gas supply stabilises. However, due to high inflation, higher real interest rates and declining real incomes, the economy is likely to remain weak. In its spring forecast, the Halle Institute for Economic Research (IWH) expects production to grow by just 0.4% in 2023, and inflation to remain high at 5.8%.

Konjunktur aktuell: Gasspeicher voll – Konjunkturaussichten weniger trüb
Konjunktur aktuell,
No. 1,
2023
Abstract
Im Frühjahr 2023 wirken gegenläufige Kräfte auf die Weltwirtschaft: Das Ende des Corona-Lockdowns in China gibt vor allem dem asiatischen Raum einen Schub, doch die anhaltend hohe Inflation belastet die fortgeschrittenen Volkswirtschaften weltweit. Alles in allem bleibt die internationale Konjunktur 2023 schwach. Für die deutsche Wirtschaft blieb der vielfach erwartete deutliche Einbruch aus, denn die Gasversorgungslage hat sich zunächst stabilisiert. Dennoch dürfte die Konjunktur wegen der Energiekosten, hoher Inflation, gestiegener Realzinsen und rückläufiger Realeinkommen schwach bleiben. Das Bruttoinlandsprodukt dürfte im Jahr 2023 um lediglich 0,4% zulegen, und die Inflationsrate bleibt mit 5,8% hoch.

Economic growth, public finances and greenhouse gas emissions in the medium term
According to the Halle Institute for Economic Research (IWH) and its medium-term projection of the German economy, growth in the next six years will be about the same as in the past six years, at 1% per year. The national budget will remain in deficit, but the debt level will decline again relative to the gross domestic product (GDP) from 2024 onwards. At this rate of economic expansion, greenhouse gas emissions will continue to decline in the medium term, but at a much slower rate than necessary to meet the national emission reduction targets.

No deep recession despite energy crisis and rise in interest rates
High energy prices and deteriorating financial conditions are weighing on the German economy. However, the period of weakness over the winter is likely to be moderate, partly because the energy price brakes are supporting private incomes. The Halle Institute for Economic Research (IWH) forecasts that due to the recovery from the pandemic in the first three quarters, gross domestic product (GDP) is estimated to have increased by 1.8% in 2022. Due to high energy prices, however, GDP will slightly decline in the winter months and stagnate on average in 2023. Inflation will fall from 7.8% in 2022 to 6.5% in 2023.

Wirtschaftswachstum, Staatsfinanzen und Treibhausgas-Emissionen in der mittleren Frist

Konjunktur aktuell,
No. 4,
2022
Abstract
Die mittelfristige Projektion der gesamtwirtschaftlichen Lage in Deutschland beinhaltet, dass das Wirtschaftswachstum mit 1% pro Jahr in den kommenden sechs Jahren in etwa genauso hoch ausfällt wie in den vergangenen sechs Jahren. Der Staatshaushalt bleibt im Defizit, aber der Schuldenstand geht relativ zum Bruttoinlandsprodukt ab dem Jahr 2024 wieder zurück. Bei diesem Tempo der wirtschaftlichen Expansion werden die Emissionen mittelfristig zwar weiter zurückgehen, aber deutlich langsamer als nötig, um die nationalen Klimaschutzziele zu erreichen.
