Macroeconomic Analyses and Forecasts

This research group belongs to the IWH Research Cluster Macroeconomic Dynamics and Stability. The group comprises all macroeconomic analyses, forecasts and policy papers that are carried out on a regular basis at the IWH. These reports contribute significantly to the IWH being one of the leading economic research institutes in Germany. The group focuses on current macroeconomic perspectives in Germany. However, forecasts for an open economy like the German one have to start from thorough and up-to-date analysis of the world economy. Special attention is given to East Germany, Central European countries, and to the European Union as a whole.

Research in this group is linked closely to other projects within the cluster that focus on publishing research papers in refereed journals. In particular, econometric tools developed by Research Group Econometric Tools for Macroeconomic Forecasting are applied for the macroeconomic projections, and policy conclusions derived by Research Group Monetary Aggregates, Asset Prices and Real Outcomes are important building blocks for policy recommendations.

IWH Data Project: IWH Macrometer: Macroeconomic Database for the German Länder, East and West Germany

All of the group’s macroeconomic analyses, forecasts and policy papers are available via the Current Forecasting section.

The joint economic forecast is an instrument for evaluating the overall economic situation and development in Germany, the euro area and the rest of the world. For this purpose, forecasts of economic activity are generated for the global economy and its major regions. Economic policy recommendations are derived from these forecasts for the euro area and the German economy. The objective of the joint diagnosis, which is commissioned by the Federal Finance Ministry, is to produce a uniform evaluation by all participating institutes. The results are published twice a year as spring and fall forecasts.

Deutsche Wirtschaft stagniert – Jetzt Wachstumskräfte stärken

Ferdinand Fichtner Roland Döhrn Oliver Holtemöller Timo Wollmershäuser

in: Wirtschaftsdienst , No. 10, 2014

Abstract

In ihrem Herbstgutachten 2014 prognostizieren die Institute in der Gemeinschaftsdiagnose einen Anstieg des Bruttoinlandsprodukts (BIP) von 1,3% (68%-Prognoseintervall: 1,1% bis 1,5%) für das Jahr 2014. Für das kommende Jahr erwarten sie einen Anstieg um 1,2%. Vor einem halben Jahr waren noch Veränderungsraten von 1,9% für dieses und 2,0% für kommendes Jahr erwartet worden. Die Änderung der Prognose basiert zum Teil auf einer veränderten Datengrundlage; das Statistische Bundesamt hat im September 2014 die Ergebnisse der Generalrevision der Volkswirtschaftlichen Gesamtrechnungen (VGR) vorgelegt. Wichtiger ist aber, dass seit dem Frühjahr immer mehr Indikatoren auf eine geringere konjunkturelle Dynamik in der zweiten Jahreshälfte hindeuten.

Gemeinschaftsdiagnose im Frühjahr 2014

Oliver Holtemöller Axel Lindner

in: Wirtschaftsdienst , No. 5, 2014

Abstract

Die Gemeinschaftsdiagnose prognostiziert für Deutschland in diesem und im nächsten Jahr einen Aufschwung, den vor allem die Binnennachfrage trägt. Die Wirtschaftsforschungsinstitute befürchten allerdings, dass sich ein Konjunktureinbruch in Russland negativ auf das deutsche Wachstum auswirken könnte. Von einem flächendeckenden Mindestlohn werden vor allem ungünstige Entwicklungen bei der Zahl der Erwerbstätigen erwartet.

The Minimum Wage Effects on Skilled Crafts Sector in Saxony-Anhalt

Hans-Ulrich Brautzsch Birgit Schultz

in: IWH Discussion Papers , No. 31, 2017

Abstract

This paper examines the effects of the minimum wage introduction in Germany in 2015 on the skilled crafts sector in Saxony-Anhalt. Using novel survey data on the skilled crafts sector in Saxony-Anhalt, we examine three questions: (1) How many employees are affected by the minimum wage introduction in the skilled crafts sector in Saxony- Anhalt? (2) What are the effects of the minimum wage introduction? (3) How have firms reacted to wage increase? We find that about 8% of all employees in the skilled crafts sector in Saxony-Anhalt are directly affected by the minimum wage introduction. A difference-in-difference estimation reveals no significant employment effects of the minimum wage introduction. We test for alternative adjustment strategies and observe a significant increase of output prices.

Employment Effects of Introducing a Minimum Wage: The Case of Germany

Oliver Holtemöller Felix Pohle

in: IWH Discussion Papers , No. 28, 2017

Abstract

This paper contributes to the empirical literature on the employment effects of minimum wages. We analysed the introduction of a statutory minimum wage in Germany in 2015 exploiting cross-sectional variation of the minimum wage affectedness. We construct two variables that measure the affectedness for approximately 300 state-industry combinations based on aggregate monthly income data. The estimation strategy consists of two steps. We test for (unidentified) structural breaks in a model with cross-section specific trends to control for state-industry specific developments prior to 2015. In a second step, we test whether the trend deviations are correlated with the minimum wage affectedness. To identify the minimum wage effect on employment, we assume that the minimum wage introduction is exogenous. Our results point towards a negative effect on marginal employment and a positive effect on socially insured employment. Furthermore, we analyse if the increase in socially insured employment is systematically related to the reduction of marginal employment but do not detect evidence.

Multidimensional Well-being and Regional Disparities in Europe

Jörg Döpke A. Knabe Cornelia Lang Philip Maschke

in: IWH Discussion Papers , No. 13, 2016

Abstract

Using data from the OECD Regional Well-Being Index – a set of quality-of-life indicators measured at the sub-national level, we construct a set of composite well-being indices. We analyse the extent to which the choice of five alternative aggregation methods affects the well-being ranking of regions. We find that regional inequality in these composite measures is lower than regional inequality in gross-domestic product (GDP) per capita.

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.

Die Learning Economy aus Netzwerkperspektive: Mechanismen und Probleme

Michael Schwartz

in: Jenaer Beiträge zur Wirtschaftsforschung , No. 4, 2006

Abstract

Im Mittelpunkt der gegenwärtigen ökonomischen Entwicklung steht verstärkt Wissen als fundamentale Ressource und Triebkraft wirtschaftlichen Wachstums sowie Lernen als der bedeutendste Prozess. Diese Sichtweise wird durch das theoretische Konstrukt der Learning Economy beschrieben. Die Organisationsform des Netzwerkes gilt dabei als geeignetes Arrangement, um die Teilnahme an Lernprozessen sowie den Zugangs zu einer breiten und diversifizierten Wissensbasis zu gewährleisten. In der vorliegenden Arbeit werden im Rahmen der konzeptionellen Charakteristika der Learning Economy die möglichen Ausprägungen einer aktiven Netzwerktätigkeit, die erfolgsdeterminierenden Mechanismen eines Netzwerkes als auch die mit einem Netzwerkarrangement verbundenen Probleme dargelegt. Es zeigt sich einerseits, dass Netzwerke grundsätzlich einen geeigneten Mechanismus darstellen, um den Notwendigkeiten einer Learning Economy zu begegnen. Andererseits wird ersichtlich, dass die Funktionsfähigkeit von Netzwerken und das Ausschöpfen der vorhandenen Möglichkeiten keinesfalls ohne konstante Anstrengungen der Partner und ein detailliertes Verständnis der zentralen Wirkungszusammenhänge erreicht werden kann. Daher ist die zum Teil euphorisch praktizierte Netzwerkdiskussion in mancher Hinsicht differenziert zu betrachten. Besonders der Abfluss ökonomisch sensiblen Wissens, der nicht-wechselseitige Wissensaustausch sowie die Abschottung bestimmter regionaler Netzwerkstrukturen können schwerwiegende Folgen nach sich ziehen.
