Joint Economic Forecast Spring 2017: Upturn in Germany strengthens in spite of global economic risks
The German economy is already in the fifth year of a moderate upturn. According to the Gemeinschaftsdiagnose (GD, joint economic forecast) that was prepared by Germany’s five leading economic research institutes on behalf of the Federal Government, capacity utilization is gradually increasing, and aggregate production capacities are now likely to have slightly exceeded their normal utilisation levels. However, cyclical dynamics remain low compared to earlier periods of recoveries, as consumption expenditures, which do not exhibit strong fluctuations, have been the main driving force so far. In addition, net migration increases potential output, counteracting a stronger capacity tightening. “Gross domestic product (GDP) is expected to expand by 1.5% (1.8% adjusted for calendar effects) and 1.8% in the next year. Unemployment is expected to fall to 6.1% in 2016, to 5.7% in 2017 and 5.4% in 2018”, says Oliver Holtemöller, Head of the Department Macroeconomics and vice president of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association. Inflation is expected to increase markedly over the forecast horizon. After an increase in consumer prices of only 0.5% in 2016, the inflation rate is expected to rise to 1.8% in 2017 and 1.7% in 2018. The public budget surplus will reduce only modestly. Public finances are slightly stimulating economic activity in the current year and are cyclically neutral in the year ahead.

The state as a pioneering customer: How public demand can drive private innovation
Especially in technology-intensive industries, demand from the state can expand private markets and create incentives for privately funded research and development, a new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows.

The German Economy: Employment Boom in Germany, but no Overheating of the Economy
Employment in Germany continues to increase healthily, and private consumption expands due to rising real incomes. Investment in equipment, however, remains modest. Overall, economic demand is expanding at roughly the growth rate of potential Gross Domestic Product (GDP), and the output gap is nearly closed. “In 2017, GDP will increase by 1.3% and thus at a lower rate than in the previous year, but this is only due to fewer working days and not to sliding demand,” says Oliver Holtemoeller, Head of the Department Macroeconomics and IWH vice president.

The German Economy: Economic Activity Spurred by Private Consumption and Construction
German economic activity remains robust due to strong domestic demand. IWH forecasts gross domestic product (GDP) to increase by 1.3% in 2017. The growth rate is half a percentage point lower than in 2016 due to calendar effects and a negative contribution of external trade. Consumer price inflation also remains modest (1.3%). “Unemployment is expected to increase slightly due to a protracted integration of refugees into the labor market”, says Oliver Holtemöller, Head of the Department Macroeconomics and IWH vice president

Joint Economic Forecast: German Economy on Track – Economic Policy needs to be Realigned
Thanks to a stable job market and solid consumption, the German economy is experiencing a moderate upswing. The GDP is expected to increase by 1.9 percent this year, 1.4 percent in 2017, and 1.6 percent in 2018, according to the Gemeinschaftsdiagnose (GD, joint economic forecast) that was prepared by five of Europe’s leading economic research institutes on behalf of the Federal Government. The most recent GD, which was released in April, predicted a GDP growth rate of 1.6 percent for 2016 and 1.5 percent for 2017.

Impulse Response Analysis in a Misspecified DSGE Model: A Comparison of Full and Limited Information Techniques
Sebastian Giesen, Rolf Scheufele
Applied Economics Letters,
No. 3,
2016
Abstract
In this article, we examine the effect of estimation biases – introduced by model misspecification – on the impulse responses analysis for dynamic stochastic general equilibrium (DSGE) models. Thereby, we use full and limited information estimators to estimate a misspecified DSGE model and calculate impulse response functions (IRFs) based on the estimated structural parameters. It turns out that IRFs based on full information techniques can be unreliable under misspecification.

The Diablo 3 Economy: An Agent Based Approach
Makram El-Shagi, Gregor von Schweinitz
Computational Economics,
No. 2,
2016
Abstract
Designers of MMOs such as Diablo 3 face economic problems much like policy makers in the real world, e.g. inflation and distributional issues. Solving economic problems through regular updates (patches) became as important to those games as traditional gameplay issues. In this paper we provide an agent framework inspired by the economic features of Diablo 3 and analyze the effect of monetary policy in the game. Our model reproduces a number of features known from the Diablo 3 economy such as a heterogeneous price development, driven almost exclusively by goods of high quality, a highly unequal wealth distribution and strongly decreasing economic mobility. The basic framework presented in this paper is meant as a stepping stone to further research, where our evidence is used to deepen our understanding of the real-world counterparts of such problems. The advantage of our model is that it combines simplicity that is inherent to model economies with a similarly simple observable counterpart (namely the game environment where real agents interact). By matching the dynamics of the game economy we can thus easily verify that our behavioral assumptions are good approximations to reality.

Refugee Migration – A Global Humanitarian Crisis Reaches Germany
Policy Brief Nr. 01/2015,
No. 1,
2015
Abstract
In this Policy Brief, the issue of current refugee migration to Europe will be discussed from various perspectives and literature on this topic from the participating institutes will be put into context. The current situation bears characteristics of a crisis. On the one hand this is due to the high numbers of refugees. On the other hand, there are fundamental problems with the existing asylum system in Europe, meaning that it is unable to handle the situation effectively – even though the problem itself is not new. The integration of incoming people into society and the labour market has linguistic, qualification-related, cultural and political dimensions.
In the Leibniz Research Alliance 'Crises in a Globalised World', 23 Leibniz institutes are working together in an interdisciplinary and transdisciplinary manner to enhance understanding of the mechanisms and dynamics of crises and their mutual interdependencies.
