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

German Economy on Track — Economic Policy Needs to Be Realigned

No. 10,
2016
Abstract
Die deutsche Wirtschaft befindet sich in einem moderaten Aufschwung. Die Gemeinschaftsdiagnose Herbst 2016 prognostiziert, dass das Bruttoinlandsprodukt 2016 um 1,9%, 2017 um 1,4% und 2018 um 1,6% zulegen dürfte. Dabei gehen von der Weltkonjunktur nur geringe stimulierende Effekte aus, zudem dürften sich in den außerordentlich niedrigen Kapitalmarktzinsen nicht nur die derzeitige Geldpolitik, sondern auch niedrige Wachstumserwartungen widerspiegeln. All dies hemmt die Ausrüstungsinvestitionen. So ist es weiterhin in erster Linie der Konsum, der den Aufschwung trägt.

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.

Qual VAR Revisited: Good Forecast, Bad Story
Makram El-Shagi, Gregor von Schweinitz
Journal of Applied Economics,
No. 2,
2016
Abstract
Due to the recent financial crisis, the interest in econometric models that allow to incorporate binary variables (such as the occurrence of a crisis) experienced a huge surge. This paper evaluates the performance of the Qual VAR, originally proposed by Dueker (2005). The Qual VAR is a VAR model including a latent variable that governs the behavior of an observable binary variable. While we find that the Qual VAR performs reasonable well in forecasting (outperforming a probit benchmark), there are substantial identification problems even in a simple VAR specification. Typically, identification in economic applications is far more difficult than in our simple benchmark. Therefore, when the economic interpretation of the dynamic behavior of the latent variable and the chain of causality matter, use of the Qual VAR is inadvisable.

Much Ado About Nothing: Sovereign Ratings and Government Bond Yields in the OECD
Makram El-Shagi
IWH Discussion Papers,
No. 22,
2016
Abstract
In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those impulse response functions using a VAR modeling ratings, yields and other macroeconomic indicators. However, given the highly stochastic nature of the precise timing of ratings, we can treat most rating adjustments as shocks. We thus no longer rely on a VAR for shock identification, making the estimation of the corresponding IRFs well suited for so called local projections – that is estimating impulse response functions through a series of separate direct forecasts over different horizons. Yet, the rare occurrence of ratings makes impulse response functions estimated through that procedure highly sensitive to individual observations, resulting in implausibly volatile impulse responses. We propose an augmentation to restrict jointly estimated local projections in a way that produces economically plausible impulse response functions.

Upturn Remains Moderate — Economic Policy Lacks Growth Orientation
Roland Döhrn, Ferdinand Fichtner, Oliver Holtemöller, Timo Wollmershäuser

No. 5,
2016
Abstract
Die deutsche Wirtschaft befindet sich in einem moderaten Aufschwung. Zu diesem Ergebnis kommt die Mitte April veröffentlichte Gemeinschaftsdiagnose der Wirtschaftsforschungsinstitute. Das Bruttoinlandsprodukt dürfte demnach in diesem Jahr um 1,6% und im kommenden Jahr um 1,5% zulegen. Getragen wird der Aufschwung vom privaten Konsum, der vom anhaltenden Beschäftigungsaufbau, den spürbaren Steigerungen der Lohn- und Transfereinkommen und den Kaufkraftgewinnen infolge der gesunkenen Energiepreise profitiert.
