Evidence-based Support for Adaptation Policies in Emerging Economies
Maximilian Banning, Anett Großmann, Katja Heinisch, Frank Hohmann, Christian Lutz, Christoph Schult
Low Carbon Economy,
No. 1,
2023
Abstract
Climate change is increasingly evident, and the design of effective climate adaptation policies is important for regional and sectoral economic growth. We propose different modelling approaches to quantify the socio-economic impacts of climate change on three vulnerable countries (Kazakhstan, Georgia, and Vietnam) and design specific adaptations. We use a Dynamic General Equilibrium (DGE) model for Vietnam and an economy-energy-emission (E3) model for the other two countries. Our simulations until 2050 show that selected adaptation measures, in particular in the agricultural sector, have positive implications for GDP. However, some adaptation measures can even increase greenhouse gas emissions. Focusing on GDP alone can lead to welfare-reducing policy decisions.

Monetary Policy in an Oil-dependent Economy in the Presence of Multiple Shocks
Andrej Drygalla
Review of World Economics,
February
2023
Abstract
Russian monetary policy has been challenged by large and continuous private capital outflows and a sharp drop in oil prices during 2014. Both contributed to significant depreciation pressures on the ruble and led the central bank to give up its exchange rate management strategy. Against this background, this work estimates a small open economy model for Russia, featuring an oil price sector and extended by a specification of the foreign exchange market to correctly account for systematic central bank interventions. We find that shocks to the oil price and private capital flows substantially affect domestic variables such as inflation and output. Simulations for the estimated actual strategy and alternative regimes suggest that the vulnerability of the Russian economy to external shocks can substantially be lowered by adopting some form of inflation targeting. Strategies to target the nominal exchange rate or the ruble price of oil prove to be inferior.

Investment, output gap, and public finances in the medium term: Implications of the Second Supplementary Budget 2021
With the Second Supplementary Budget 2021, the German government plans to allocate a reserve of 60 billion euros to the Energy and Climate Fund. This additional spending is also meant to reduce the macroeconomic follow-up costs of the pandemic. According to the IWH’s medium-term projection, the expenditure is expected to increase output by about 0.5% at the peak of its impact in 2024. “While this macroeconomic effect is welcome, the additional investment will by no means compensate for the lack of investment activity since the beginning of the pandemic,” says Oliver Holtemöller, head of the Department Macroeconomics and vice president at Halle Institute for Economic Research (IWH). Moreover, the supplementary budget is likely to reduce confidence in the reliability of the debt brake.

Economic mobility likely to increase significantly after relaxation – but also number of COVID-19 cases
The relaxation of Corona containment measures from the beginning of March 2021 lead to a significant increase in economic mobility and thus also in personal contacts in Germany. Estimates suggest that the recent relaxations increase economic mobility by more than ten percentage points and the number of new infections and deaths in Germany by 25%. Because both continued lockdowns and relaxations carry significant negative consequences, it is even more important to enable further relaxations through better testing and quarantine strategies and by increasing the pace of vaccination without putting people's health at risk.

High public deficits not only due to the pandemic – Medium-term options for fiscal policy
According to the IWH’s medium-term projection, Germany's gross domestic product will grow more slowly between 2020 and 2025 than before, not only because of the pandemic crisis, but also because the work force will decline. The resulting structural public deficits are, if the legal framework remains unchanged, likely to be higher than the debt brake allows. Consolidation measures, especially if they relate to government revenues, entail economic losses in the short term. “There is much to be said, also from a theoretical point of view, for not abolishing the debt brake, but for relaxing it to some extent,” says Oliver Holtemöller, head of the Department of Macroeconomics and vice president at Halle Institute for Economic Research (IWH).
