Konjunktur aktuell: Deutsche Konjunktur kommt langsam wieder in Schwung
Konjunktur aktuell,
No. 1,
2015
Abstract
Das Bruttoinlandsprodukt in Deutschland stieg im Jahr 2014 um 1,5% und wird im Jahr 2015 wohl um 1,3% zulegen. Nach einem schwachen Winterhalbjahr dürfte die deutsche Konjunktur langsam wieder in Schwung kommen, auch weil der niedrige Ölpreis für deutsche Haushalte und Unternehmen eine Kostenentlastung bedeutet. Der Verbraucherpreisindex dürfte im Jahr 2015 um 1,1% zunehmen. Die Arbeitslosenquote wird wohl auf ihrem aktuellen Niveau von 6,4% verharren, obwohl vom flächendeckenden Mindestlohn für sich genommen negative Beschäftigungseffekte ausgehen werden.

Financial Integration, Housing, and Economic Volatility
Elena Loutskina, Philip E. Strahan
Journal of Financial Economics,
No. 1,
2015
Abstract
The Great Recession illustrates the sensitivity of the economy to housing. This paper shows that financial integration, fostered by securitization and nationwide branching, amplified the positive effect of housing price shocks on the economy during the 1994–2006 period. We exploit variation in credit supply subsidies across local markets from government-sponsored enterprises to measure housing price changes unrelated to fundamentals. Using this instrument, we find that house price shocks spur economic growth. The effect is larger in localities more financially integrated, through both secondary loan market and bank branch networks. Financial integration thus raised the effect of collateral shocks on local economies, increasing economic volatility.

Understanding the Great Recession
Mathias Trabandt, Lawrence J. Christiano, Martin S. Eichenbaum
American Economic Journal: Macroeconomics,
No. 1,
2015
Abstract
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.

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 Levelling Effect of Product Market Competition on Gender Wage Discrimination
Boris Hirsch, Michael Oberfichtner, Claus Schnabel
IZA Journal of Labor Economics,
No. 19,
2014
Abstract
Using linked employer–employee panel data for West Germany that include direct information on the competition faced by plants, we investigate the effect of product market competition on the gender pay gap. Controlling for match fixed effects, we find that intensified competition significantly lowers the unexplained gap in plants with neither collective agreements nor a works council. Conversely, there is no effect in plants with these types of worker codetermination, which are unlikely to have enough discretion to adjust wages in the short run. We also document a larger competition effect in plants with few females in their workforces. Our findings are in line with Beckerian taste-based employer wage discrimination that is limited by competitive forces.

Do We Need New Modelling Approaches in Macroeconomics?
Claudia M. Buch, Oliver Holtemöller
Financial Cycles and the Real Economy: Lessons for CESEE Countries,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.

Abstract
Im Rahmen des IWH/IAB-Workshops zur Arbeitsmarktpolitik am 1. und 2. Oktober 2014 in Halle (Saale) trafen sich zum elften Mal Vertreter aus Wissenschaft, Politik, Verwaltung und Wirtschaft, um sich aus ökonomischer und soziologischer Sicht über neue Entwicklungen und Erkenntnisse zu den Themen langfristiger Sozialleistungsbezug und Langzeitarbeitslosigkeit auszutauschen. Der Fokus der Workshops, die als Bindeglied zwischen Theorie und Praxis konzipiert sind, lag dabei auf den Ursachen und Konsequenzen der Langzeitarbeitslosigkeit sowie auf möglichen Lösungsansätzen.

Kommentar: Betriebsgrößenstruktur und Arbeitsmarktergebnisse
Steffen Müller
Wirtschaft im Wandel,
No. 5,
2014
Abstract
Trotz aller Fortschritte bei der wirtschaftlichen Angleichung Ost- und Westdeutschlands seit der Vereinigung wird in der öffentlichen Debatte häufig auf fortbestehende Unterschiede bei Löhnen und Arbeitsproduktivität verwiesen. Als Erklärung hierfür wird der vergleichsweise geringe Anteil großer und damit in der Regel auch produktiverer und besser zahlender Betriebe in Ostdeutschland angeführt. Die Größe eines Betriebes ist jedoch – von möglichen Skalenerträgen einmal abgesehen – für sich genommen kein Bestimmungsfaktor für ökonomische Prosperität. Für das Verständnis der Folgen einer kleinteilig organisierten Wirtschaft muss geklärt werden, über welche Mechanismen die Betriebsgrößenstruktur auf Löhne und Arbeitsproduktivität wirkt.

The Dynamics of Bank Spreads and Financial Structure
Reint E. Gropp, Christoffer Kok, J.-D. Lichtenberger
Quarterly Journal of Finance,
No. 4,
2014
Abstract
This paper investigates the effect of within banking sector competition and competition from financial markets on the dynamics of the transmission from monetary policy rates to retail bank interest rates in the euro area. We use a new dataset that permits analysis for disaggregated bank products. Using a difference-in-difference approach, we test whether development of financial markets and financial innovation speed up the pass through. We find that more developed markets for equity and corporate bonds result in a faster pass-through for those retail bank products directly competing with these markets. More developed markets for securitized assets and for interest rate derivatives also speed up the transmission. Further, we find relatively strong effects of competition within the banking sector across two different measures of competition. Overall, the evidence supports the idea that developed financial markets and competitive banking systems increase the effectiveness of monetary policy.
