The Quantity Theory Revisited: A New Structural Approach
Makram El-Shagi, Sebastian Giesen
Macroeconomic Dynamics,
No. 1,
2015
Abstract
We propose a unified identification scheme to identify monetary shocks and track their propagation through the economy. We combine three approaches dealing with the consequences of monetary shocks. First, we adjust a state space version of the P-star type model employing money overhang as the driving force of inflation. Second, we identify the contemporaneous impact of monetary policy shocks by applying a sign restriction identification scheme to the reduced form given by the state space signal equations. Third, to ensure that our results are not distorted by the measurement error exhibited by the official monetary data, we employ the Divisia M4 monetary aggregate provided by the Center for Financial Stability. Our approach overcomes one of the major difficulties of previous models by using a data-driven identification of equilibrium velocity. Thus, we are able to show that a P-star model can fit U.S. data and money did indeed matter in the United States.

Switching to Exchange Rate Flexibility? The Case of Central and Eastern European Inflation Targeters
Andrej Drygalla
FIW Working Paper,
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.

Interrelationship between Industrial and Innovation Development in East Germany
Gerhard Heimpold
Region: Ekonomika i Soziologija,
No. 2,
2015
Abstract
The article demonstrates that the most important reason for the slowdown and stagnation of economic convergence in East Germany is the weakness in terms of research and development and innovation. It analyzes the interrelationship between industrial and innovative development in the East German federal states since 1990. The article shows how the East German industry sector and its R&D activities looked like in the late 1980s and which transition it had undergone in the course of privatization. The industrial development of the new federal states after 1990 is analyzed. The paper reveals structural shortcomings in East Germany's economy and considers their impact on the progress in R&D.

Business Cylce Effects of the 2014 Oil Price Slump
Andrej Drygalla, Stefan Gießler, Oliver Holtemöller
Wirtschaftskammer Österreich: Wirtschaftspolitische Blätter,
No. 4,
2015
Abstract
Der Ölpreis ist seit der Mitte des Jahres 2014 deutlich gesunken. Die konjunkturellen Effekte von Ölpreisänderungen hängen davon ab, ob nachfrageseitige oder angebotsseitige Ursachen die Preisänderung auslösen. Im vorliegenden Beitrag wird der Ölpreisrückgang seit Mitte des Jahres 2014 in eine konjunkturelle und eine ölmarktspezifische Komponente zerlegt. Anschließend wird mit dem internationalen Konjunkturmodell des IWH analysiert, welchen Beitrag der Ölpreisrückgang zur konjunkturellen Entwicklung seit Mitte des Jahres 2014 geleistet hat und welche Effekte bis zum Ende des Jahres 2016 noch zu erwarten sind. Es werden sowohl ölexportierende (Russland) als auch ölimportierende Länder (G7-Länder und Österreich) betrachtet. Das Bruttoinlandsprodukt wird im betrachteten Länderkreis in den USA und in Japan am stärksten stimuliert, während der Ölpreisfall in Russland das Bruttoinlandsprodukt deutlich dämpft.

Returns to Skills around the World: Evidence from PIAAC
Eric A. Hanushek, Guido Schwerdt, Simon Wiederhold, Ludger Woessmann
European Economic Review,
January
2015
Abstract
Existing estimates of the labor-market returns to human capital give a distorted picture of the role of skills across different economies. International comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital, and evidence incorporating direct measures of cognitive skills is mostly restricted to early-career workers in the United States. Analysis of the new PIAAC survey of adult skills over the full lifecycle in 23 countries shows that the focus on early-career earnings leads to underestimating the lifetime returns to skills by about one quarter. On average, a one-standard-deviation increase in numeracy skills is associated with an 18 percent wage increase among prime-age workers. But this masks considerable heterogeneity across countries. Eight countries, including all Nordic countries, have returns between 12 and 15 percent, while six are above 21 percent with the largest return being 28 percent in the United States. Estimates are remarkably robust to different earnings and skill measures, additional controls, and various subgroups. Instrumental-variable models that use skill variation stemming from school attainment, parental education, or compulsory-schooling laws provide even higher estimates. Intriguingly, returns to skills are systematically lower in countries with higher union density, stricter employment protection, and larger public-sector shares.

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.

Gemeinschaftsdiagnose im Herbst 2014: Deutsche Wirtschaft stagniert – Jetzt Wachstumskräfte stärken (Kurzfassung)
Wirtschaft im Wandel,
No. 5,
2014
Abstract
Die deutsche Wirtschaft dürfte in diesem Jahr um 1,3% und im kommenden Jahr um 1,2% expandieren. Das prognostizieren die an der Gemeinschaftsdiagnose beteiligten Wirtschaftsforschungsinstitute in ihrem Herbstgutachten. Demzufolge hat sich die Konjunktur in Deutschland merklich abgekühlt. Nachdem die Wirtschaftsleistung im zweiten Quartal gesunken war und im dritten Vierteljahr wohl stagniert hat, kommt der Konjunkturmotor nur schwerlich wieder auf Touren. Schwach ist sowohl die Binnennachfrage – das Konsumklima hat sich zuletzt verschlechtert und die Unternehmen halten sich mit Investitionen weiterhin zurück – als auch die Auslandsnachfrage. Belastend wirken das mäßige Expansionstempo der Weltwirtschaft, die auch im Prognosezeitraum niedrige Dynamik im Euroraum und der Gegenwind von der Wirtschaftspolitik. In diesem Umfeld sprechen sich die Wirtschaftsforschungsinstitute für eine Stärkung der Wachstumskräfte und günstigere Rahmenbedingungen für Investitionen aus. Der finanzielle Spielraum für ein investitionsfreundlicheres Steuersystem und mehr Ausgaben in wachstumsförderlichen Bereichen wie Sach- und Humankapital sei vorhanden.
