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.

Aktuelle Trends: Jeder vierte Beschäftigte in Ostdeutschland verdiente im Jahr 2011 weniger als 8,50 Euro je Stunde
Hans-Ulrich Brautzsch, Birgit Schultz
Wirtschaft im Wandel,
No. 2,
2013
Abstract
In der Öffentlichkeit wird gegenwärtig die Einführung eines flächendeckenden Mindestlohnes in Höhe von 8,50 Euro je Stunde diskutiert. Eine Auszählung des Sozio-oekonomischen Panels (SOEP) durch das IWH ergab, dass im Jahr 2011 – aktuellere Daten liegen nicht vor – im Osten 25% und in Westdeutschland knapp 12% der abhängig Beschäftigten einen vereinbarten Bruttostundenverdienst von weniger als 8,50 Euro erhalten haben. Etwa 38% der ostdeutschen Arbeitnehmer hatten im Jahr 2011 einen Bruttostundenlohn von weniger als zehn Euro; im Westen waren es 20%. Berücksichtigt man die durchschnittliche Lohnsteigerung, so dürfte im Jahr 2012 der Anteil der Beschäftigten mit einem Stundenlohn von weniger als 8,50 Euro im Osten 24% und im Westen 11% betragen haben.

Women Move Differently: Job Separations and Gender
Boris Hirsch, Claus Schnabel
Journal of Labor Research,
No. 4,
2012
Abstract
Using a large German linked employer–employee data set and methods of competing risks analysis, this paper investigates gender differences in job separation rates to employment and nonemployment. In line with descriptive evidence, we find lower job-to-job and higher job-to-nonemployment transition probabilities for women than men when controlling for individual and workplace characteristics and unobserved plant heterogeneity. These differences vanish once we allow these characteristics to affect separations differently by gender. When additionally controlling for wages, we find that both separation rates are considerably lower and also significantly less wage-elastic for women than for men, suggesting an interplay of gender differences in transition behaviour and the gender pay gap.

The Synchronization of Wage Dynamics across EMU Members: A Test of the Endogeneity Hypothesis
Herbert S. Buscher, Hubert Gabrisch
Empirica,
No. 3,
2012
Abstract
We test the hypothesis of an endogenous currency area for the labor market of the Euro area: has the introduction of a common currency caused wage dynamics to become more synchronized and to be able to cushion for asymmetric shocks? Trade intensity, sector specialization and financial integration are tested for being the driving forces for the endogenous synchronization of wage dynamics. We use regression techniques with instrument variables, and find evidence of persistent asymmetries in nominal wage formation, despite a single currency and monetary policy. We explain the result with more specialization following financial integration, and with still existing differences in wage formation and labor market institutions. We conclude that the euro zone is not endogenous with respect to wage formation. Rather, there are incentives for beggar-thy-neighbor policies in the Euro area.

Im Fokus: Löhne in Deutschland: Spreizung zwischen den Branchen nimmt zu
Birgit Schultz
Wirtschaft im Wandel,
No. 6,
2012
Abstract
Die Reallöhne in Deutschland sind viele Jahre in Folge gesunken bzw. stagnierten. Dies wird häufig als Grund sowohl für die günstige Wettbewerbsposition im Exportbereich als auch für die Konsumzurückhaltung der privaten Haushalte angeführt. Der Beitrag beschreibt die Lohnentwicklung in Deutschland in den vergangenen Jahren. Dabei wird deutlich, dass sich in den letzten Jahren Niedrig- und Hochlohnbranchen herausgebildet haben. Diese Lohnspreizung wurde letztlich durch Marktmechanismen hervorgerufen. So erhöhten sich die Reallöhne in Branchen mit guter Nachfrage stärker als in Branchen in einem schwierigen Marktumfeld. Die Durchsetzbarkeit von höheren Preisen für die angebotenen Güter dürfte ebenso wie Knappheiten auf sektoralen Arbeitsmärkten bei der Lohnfindung eine Rolle spielen.

Do Women Benefit from Competitive Markets? Product Market Competition and the Gender Pay Gap in Germany
Boris Hirsch, Michael Oberfichtner, Claus Schnabel
Economics Bulletin,
No. 2,
2012
Abstract
Using a large linked employer–employee dataset for Germany with a direct plant-level measure of product market competition and controlling for job-cell fixed effects, we investigate whether relative wages of women benefit from strong competition. We find that the unexplained gender pay gap is about 2.4 log points lower in West German plants that face strong product market competition than in those experiencing weak competition, whereas no such link shows up for East Germany.

Central Bank, Trade Unions, and Reputation – Is there Room for an Expansionist Manoeuvre in the European Union?
Toralf Pusch, A. Heise
A. Heise (ed.), Market Constellation Research: A Modern Governance Approach to Macroeconomic Policy. Institutionelle und Sozial-Ökonomie, Bd. 19,
2011
Abstract
The objective of this reader is manifold: On the one hand, it intends to establish a new perspective at the policy level named 'market constellations': institutionally embedded systems of macroeconomic governance which are able to explain differences in growth and employment developments. At the polity level, the question raised is whether or not market constellations can be governed and, thus, whether institutions can be created which will provide the incentives necessary for favourable market constellations.

International Trade Patterns and Labour Markets – An Empirical Analysis for EU Member States
Götz Zeddies
International Journal of Economics and Business Research,
2012
Abstract
During the last decades, international trade flows of the industrialized countries became more and more intra-industry. At the same time, employment perspectives particularly of the low-skilled by tendency deteriorated in these countries. This phenomenon is often traced back to the fact that intra-industry trade (IIT), which should theoretically involve low labour market adjustment, became increasingly vertical in nature. Against this background, the present paper investigates the relationship between international trade patterns and selected labour market indicators in European countries. As the results show, neither inter- nor vertical intra-industry trade (VIIT) do have a verifiable effect on wage spread in EU member states. As far as structural unemployment is concerned, the latter increases only with the degree of countries’ specialization on capital intensively manufactured products in inter-industry trade relations. Only for unemployment of the less-skilled, a slightly significant impact of superior VIIT seems to exist.

A Macroeconomist’s View on EU Governance Reform: Why and How to Establish Policy Coordination?
Hubert Gabrisch
Economic Annals,
No. 191,
2011
Abstract
This paper discusses the need for macroeconomic policy coordination in the E(M)U. Coordination of national policies with cross-border effects does not exist at the macroeconomic level, although requested by the EU Treaty. The need for coordination stems from current account imbalances, which origin in market-induced capital flows, destabilizing the real exchange rates between low and high wage countries. The recent attempts of the Commission and the European Council to reform E(M)U governance do not address this problem and thus remain incapable to protect against future instability.

Introducing Financial Frictions and Unemployment into a Small Open Economy Model
Mathias Trabandt, Lawrence J. Christiano, Karl Walentin
Journal of Economic Dynamics & Control,
No. 12,
2011
Abstract
Which are the main frictions and the driving forces of business cycle dynamics in an open economy? To answer this question we extend the standard new Keynesian model in three dimensions: we incorporate financing frictions for capital, employment frictions for labor and extend the model into a small open economy setting. We estimate the model on Swedish data. Our main results are that (i) a financial shock is pivotal for explaining fluctuations in investment and GDP. (ii) The marginal efficiency of investment shock has negligible importance. (iii) The labor supply shock is unimportant in explaining GDP and no high frequency wage markup shock is needed.
