Effects of Incorrect Specification on the Finite Sample Properties of Full and Limited Information Estimators in DSGE Models
Sebastian Giesen, Rolf Scheufele
Abstract
In this paper we analyze the small sample properties of full information and limited information estimators in a potentially misspecified DSGE model. Therefore, we conduct a simulation study based on a standard New Keynesian model including price and wage rigidities. We then study the effects of omitted variable problems on the structural parameters estimates of the model. We find that FIML performs superior when the model is correctly specified. In cases where some of the model characteristics are omitted, the performance of FIML is highly unreliable, whereas GMM estimates remain approximately unbiased and significance tests are mostly reliable.

Real Effective Exchange Rate Misalignment in the Euro Area: A Counterfactual Analysis
Makram El-Shagi, Axel Lindner, Gregor von Schweinitz
Abstract
Were real effective exchange rates (REER) of Euro area member countries drastically misaligned at the outbreak of the global financial crisis? The answer is difficult to determine because economic theory gives no simple guideline for determining the equilibrium values of real exchange rates, and the determinants of those values might have been distorted as well. To overcome these limitations, we use synthetic matching to construct a counterfactual economy for each member as a linear combination of a large set of non-Euro area countries. We find that Euro area crisis countries are best described by a mixture of advanced and emerging economies. Comparing the actual REER with those of the counterfactuals gives sensible estimates of the misalignments at the start of the crisis: All peripheral countries were strongly overvalued, while high undervaluation is only observed for Finland.

Plant-based Bioeconomy in Central Germany - Mapping of Actors, Industries and Places
Wilfried Ehrenfeld, Frieder Kropfhäußer
Abstract
The challenges facing the 21st century, presented by a growing global population, range from food security to sustainable energy supplies to the diminishing availability of fossil raw materials. An attempt to solve these problems is made by using the concept of bioeconomy. Plants, in particular, possess an important function in this context - they can be used either as a source of food or, in the form of biomass, for industrial or energy purposes. Linking industrial and agricultural research and production, bioeconomy provides growth potential, in particular in rural areas.
The aim of this article is therefore to outline the status of plant-based bioeconomy
in three states of Central Germany - Saxony, Saxony-Anhalt and Thuringia - and to compare this to German plant-based bioeconomy. We take an in-depth look at the different sectors and outline the industries involved, the location and age of the enterprises as well as the distribution of important NACE codes. In conclusion, we highlight the significant number of new or small enterprises and the high research and innovation rate of Central Germany. We also stress the future potential of Central German plant-based bioeconomy as well as the importance of a more plant-focusedview of the technology sector.

The Structure and Evolution of Intersectoral Technological Complementarity in R&D in Germany from 1990 to 2011
Matthias Brachert, T. Broekel
Abstract
Technological complementarity is argued to be a crucial element for effective Research and Development (R&D) collaboration. The real structure is, however, still largely unknown. Based on the argument that organizations’ knowledge resources must fit for enabling collective learning and innovation, we use the co-occurrence of firms in collaborative R&D projects in Germany to assess inter-sectoral technological complementarity between 129 sectors. The results are mapped as complementarity space for the Germany economy. The space and its dynamics from 1990 to 2011 are analyzed by means of social network analysis.
The results illustrate sectors being complements both from a dyadic and portfolio/ network perspective. This latter is important, as complementarities may only become fully effective when integrated in a complete set of different knowledge resources from multiple sectors. The dynamic perspective moreover reveals the shifting demand for knowledge resources among sectors at different time periods.

Aktuelle Trends: Ertragslage der ostdeutschen Betriebe verbessert sich stetig
Steffen Müller
Wirtschaft im Wandel,
Nr. 3,
2017
Abstract
Ostdeutschland weist auch mehr als 25 Jahre nach der deutschen Vereinigung eine um circa ein Viertel geringere Arbeitsproduktivität als Westdeutschland auf. Wesentlich geringer ist der Rückstand jedoch bei der Ertragslage. Vor elf Jahren machten etwa 70% der westdeutschen Betriebe und 65% der ostdeutschen Betriebe Gewinne. Nach einem kurzen Knick um die Wirtschafts- und Finanzkrise 2009 ist dieser Anteil kontinuierlich auf 80% im Westen und 76% im Osten angestiegen. Das bedeutet, dass sich beide Landesteile bei dieser Kennzahl seit geraumer Zeit mit recht geringem Abstand im Gleichschritt bewegen.

Progressive Tax-like Effects of Inflation: Fact or Myth? The U.S. Post-war Experience
Matthias Wieschemeyer, Bernd Süssmuth
IWH Discussion Papers,
Nr. 33,
2017
Abstract
Inflation and earnings growth can push some tax payers into higher brackets in the absence of inflation-indexed schedules. Moreover, inflation may affect the composition of individuals’ income sources. As a result, depending on the relative tax burden of labour and capital, inflation may decrease or increase the difference between before-tax and after-tax income. However, whether some and if so which percentiles of the income distribution net benefit from inflation via taxation is a widely unexplored question. We make use of a novel dataset on U.S. pre-tax and post-tax income distribution series provided by Pike ty et al. (2018) for the years 1962 to 2014 to answer this question. To this end, we estimate local projections to quantify dynamic effects. We find that inflation shocks increase progressivity of taxation not only contemporaneously but also with some repercussion of several years after the shock. While particularly the bottom two quintiles gain in share, it is not the top but the fourth quintile that lastingly loses.

Gemeinschaftsdiagnose im Frühjahr 2014

Wirtschaftsdienst,
Nr. 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.
