Konjunktur aktuell: Deutsche Wirtschaft legt kräftig zu

Hans-Ulrich Brautzsch João Carlos Claudio Andrej Drygalla Franziska Exß Katja Heinisch Oliver Holtemöller Martina Kämpfe Konstantin Kiesel Axel Lindner Jan-Christopher Scherer Birgit Schultz Matthias Wieschemeyer Götz Zeddies

in: Konjunktur aktuell , No. 4, 2017

Abstract

Im Sommer 2017 befindet sich die Weltwirtschaft im Aufschwung. Das deutsche Bruttoinlandsprodukt dürfte nach vorliegender Prognose im Jahr 2017 wie schon im Vorjahr mit 1,9% und im Jahr 2018 mit 2,0% expandieren. Die öffentlichen Haushalte erzielen dabei weiter zunehmende Überschüsse. Der Zuwachs der Produktion in Ostdeutschland dürfte im Prognosezeitraum (wie schon in den vergangenen drei Jahren) etwas über dem in Westdeutschland liegen.

Business Cylce Effects of the 2014 Oil Price Slump

Andrej Drygalla Stefan Gießler Oliver Holtemöller

in: Wirtschaftskammer Österreich: Wirtschaftspolitische Blätter , No. 4, 2015

Abstract

The price for crude oil has dropped remarkably since the middle of the year 2014. Business cycle effects of oil price changes depend on whether these are caused by demand or supply side factors. In the present paper, the decrease in oil prices since the middle of the year 2014 is decomposed into demand side and oil-market specific factors. Subsequently, the contribution of the decline in oil prices to the economic development since the third quarter of 2014 and the expected effects until the end of the year 2016 are analyzed using the international business cycle model of the Halle Institute for Economic Research (IWH). The analysis considers both, oil-exporting countries (Russia) as well as oil-importing economies (G7 countries and Austria). Economic activity is stimulated strongest in the United States and Japan, whereas it is remarkably curbed in Russia.

Monetary Policy in an Oil-dependent Economy in the Presence of Multiple Shocks

Andrej Drygalla

in: IWH Discussion Papers , No. 14, 2017

Abstract

Russian monetary policy has been challenged by large and continuous private capital outflows and a sharp drop in oil prices during 2014, with both ongoings having put a significant depreciation pressure on the ruble and having led the central bank to eventually give up its exchange rate management strategy. Against this background, this paper 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, output and the exchange rate. Simulations of the model for the estimated actual strategy and five alternative regimes suggest that the vulnerability of the Russian economy to external shocks can substantially be lowered by adopting some form of an inflation targeting strategy. Foreign exchange intervention-based policy strategies to target the nominal exchange rate or the ruble price of oil, on the other hand, prove inferior to the policy in place.

Switching to Exchange Rate Flexibility? The Case of Central and Eastern European Inflation Targeters

Andrej Drygalla

in: FIW Working Paper, Nr. 139 , No. 139, 2015

Abstract

This paper analyzes changes in the monetary policy in the Czech Republic, Hungary, and Poland following the policy shift from exchange rate targeting to inflation targeting around the turn of the millennium. Applying a Markovswitching dynamic stochastic general equilibrium model, switches in the policy parameters and the volatilities of shocks hitting the economies are estimated and quantified. Results indicate the presence of regimes of weak and strong responses of the central banks to exchange rate movements as well as periods of high and low volatility. Whereas all three economies switched to a less volatile regime over time, findings on changes in the policy parameters reveal a lower reaction to exchange rate movements in the Czech Republic and Poland, but an increased attention to it in Hungary. Simulations for the Czech Republic and Poland also suggest their respective central banks, rather than a sound macroeconomic environment, being accountable for reducing volatility in variables like inflation and output. In Hungary, their favorable developments can be attributed to a larger extent to the reduction in the size of external disturbances.
