Resolving the Missing Deflation Puzzle
Jesper Lindé, Mathias Trabandt
Abstract
We propose a resolution of the missing deflation puzzle. Our resolution stresses the importance of nonlinearities in price- and wage-setting when the economy is exposed to large shocks. We show that a nonlinear macroeconomic model with real rigidities resolves the missing deflation puzzle, while a linearized version of the same underlying nonlinear model fails to do so. In addition, our nonlinear model reproduces the skewness of inflation and other macroeconomic variables observed in post-war U.S. data. All told, our results caution against the common practice of using linearized models to study inflation and output dynamics.

Harter Brexit würde deutschen Arbeitsmarkt besonders treffen
Sollte Großbritannien ohne Vertrag aus der Europäischen Union austreten, hätte das Folgen für den internationalen Handel und die Arbeitsmärkte in vielen Ländern, auch außerhalb Europas. Berechnungen des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) zeigen: Weltweit könnten mehr als 600 000 Arbeitskräfte betroffen sein, aber nirgends so viele wie in Deutschland.

Potential International Employment Effects of a Hard Brexit
Hans-Ulrich Brautzsch, Oliver Holtemöller
Abstract
We use the World Input Output Database (WIOD) to estimate the potential employment effects of a hard Brexit in 43 countries. In line with other studies we assume that imports from the European Union (EU) to the UK will decline by 25% after a hard Brexit. The absolute effects are largest in big EU countries which have close trade relationships with the UK like Germany and France. However, there are also large countries outside the EU which are heavily affected via global value chains like China, for example. The relative effects (in percent of total employment) are largest in Malta and Ireland. UK employment will also be affected via intermediate input production. Within Germany, the motor vehicle industry and in particular the “Autostadt” Wolfsburg are most affected.

Mindestlohnbeschäftigte: Dienstleister für den privaten Konsum oder Teilhaber am Exporterfolg? Ergebnisse einer Input-Output-Analyse
Hans-Ulrich Brautzsch, Birgit Schultz
Wirtschaftsdienst,
Nr. 1,
2019
Abstract
Im Jahr 2014 waren mehr als 38 Mio. Personen in Deutschland als Arbeitnehmer beschäftigt. Sie produzierten vor allem Güter für den Konsum, für Investitionen in Ausrüstungen und Bauten sowie den Export, aber auch Vorleistungsgüter, die als Bestandteil der Wertschöpfungsketten indirekt in deren Entstehung eingingen. Hier ist wirtschafts- und lohnpolitisch interessant, in welchen quantitativen Verhältnissen der Einsatz der Beschäftigten in der Vorleistungsgüterproduktion zur Endverwendung im Wirtschaftskreislauf steht. Dieses Interesse richtet sich nicht nur auf die Personenzahl, sondern im Besonderen auch auf deren Entlohnung. Ein Augenmerk liegt dabei bei den Beschäftigten, deren Löhne 2014 dem Mindestlohn 2015 (8,50 Euro) entsprachen.

Schneller Braunkohleausstieg hat deutliche Folgen in betroffenen Regionen
Wenn Deutschland die Braunkohleverstromung vorzeitig beendet, wird die Gesamtwirtschaft kaum beeinträchtigt. Allerdings zeigen Berechnungen des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) spürbare Effekte auf die Arbeitsmärkte des Rheinlands, Mitteldeutschlands und der Lausitz. Eine Region ist besonders betroffen von Arbeitslosigkeit und Abwanderung.

Inference in Structural Vector Autoregressions when the Identifying Assumptions are not Fully Believed: Re-evaluating the Role of Monetary Policy in Economic Fluctuations
Christiane Baumeister, James D. Hamilton
Journal of Monetary Economics,
2018
Abstract
Point estimates and error bands for SVARs that are set identified are only justified if the researcher is persuaded that some parameter values are a priori more plausible than others. When such prior information exists, traditional approaches can be generalized to allow for doubts about the identifying assumptions. We use information about both structural coefficients and impacts of shocks and propose a new asymmetric t-distribution for incorporating information about signs in a nondogmatic way. We apply these methods to a three-variable macroeconomic model and conclude that monetary policy shocks are not the major driver of output, inflation, or interest rates.

Deutschlands "Basar-Ökonomie" nach der Finanz- und Wirtschaftskrise

Abstract
Die Finanz- und Wirtschaftskrise 2008/2009 traf die deutsche Wirtschaft infolge ihrer beträchtlichen Abhängigkeit von den Weltmärkten besonders stark über den Außenhandelskanal. Der Aufsatz behandelt den Netto-Einfluss des Exportschocks auf die Wertschöpfung und Beschäftigung in Deutschland und wendet dazu die Input-Output-Analyse an.

The European Refugee Crisis and the Natural Rate of Output
Katja Heinisch, Klaus Wohlrabe
Applied Economics Letters,
Nr. 16,
2017
Abstract
The European Commission follows a harmonized approach for calculating structural (potential) output for EU member states that takes into account labour as an important ingredient. This article shows how the recent huge migrants’ inflow to Europe affects trend output. Due to the fact that the immigrants immediately increase the working population but effectively do not enter the labour market, we illustrate that the potential output is potentially upward biased without any corrections. Taking Germany as an example, we find that the average medium-term potential growth rate is lower if the migration flow is modelled adequately compared to results based on the unadjusted European Commission procedure.

The Effects of Fiscal Policy in an Estimated DSGE Model – The Case of the German Stimulus Packages During the Great Recession
Andrej Drygalla, Oliver Holtemöller, Konstantin Kiesel
Abstract
In this paper, we analyse the effects of the stimulus packages adopted by the German government during the Great Recession. We employ a standard medium-scale dynamic stochastic general equilibrium (DSGE) model extended by non-optimising households and a detailed fiscal sector. In particular, the dynamics of spending and revenue variables are modeled as feedback rules with respect to the cyclical component of output. Based on the estimated rules, fiscal shocks are identified. According to the results, fiscal policy, in particular public consumption, investment, transfers and changes in labour tax rates including social security contributions prevented a sharper and prolonged decline of German output at the beginning of the Great Recession, suggesting a timely response of fiscal policy. The overall effects, however, are small when compared to other domestic and international shocks that contributed to the economic downturn. Our overall findings are not sensitive to the allowance of fiscal foresight.

Benchmark Value-added Chains and Regional Clusters in R&D-intensive Industries
Reinhold Kosfeld, Mirko Titze
International Regional Science Review,
Nr. 5,
2017
Abstract
Although the phase of euphoria seems to be over, policy makers and regional agencies have maintained their interest in cluster policy. Modern cluster theory provides reasons for positive external effects that may accrue from interaction in a group of proximate enterprises operating in common and related fields. Although there has been some progress in locating clusters, in most cases only limited knowledge on the geographical extent of regional clusters has been established. In the present article, we present a hybrid approach to cluster identification. Dominant buyer–supplier relationships are derived by qualitative input–output analysis from national input–output tables, and potential regional clusters are identified by spatial scanning. This procedure is employed to identify clusters of German research and development-intensive industries. A sensitivity analysis reveals good robustness properties of the hybrid approach with respect to variations in the quantitative cluster composition.
