Does downward nominal wage rigidity dampen wage increases?
(2010) Beißinger, Thomas; Stüber, Heiko
Focusing on the compression of wage cuts, many empirical studies find a high degree of downward nominal wage rigidity (DNWR). However, the resulting macroeconomic effects seem to be surprisingly weak. This contradiction can be explained within an intertemporal framework in which DNWR not only prevents nominal wage cuts but also induces firms to compress wage increases. We analyze whether a compression of wage increases occurs when DNWR is binding by applying Unconditional Quantile Regression and Seemingly Unrelated Regression to a data set comprising more than 169 million wage changes. We find evidence for a compression of wage increases and only very small effects of DNWR on average real wage growth. The results indicate that DNWR does not provide a strong argument against low inflation targets.
Downward nominal wage rigidity in Europe : an analysis of European micro data from the ECHP 1994-2001
(2006) Knoppik, Christoph; Beißinger, Thomas
This paper substantially extends the limited available evidence on existence and extent of downward nominal wage rigidity in the European Union and the Euro Area. For this purpose we develop an econometric multi-country model based on Kahn?s (1997) histogram-location approach and apply it to employee micro data from the European Community Household Panel (ECHP) for twelve of the EU?s current member states. Our estimates for the degree of downward nominal wage rigidity on the national as well as the EU-wide level point to marked downward nominal wage rigidity within the European Union.
Matching und Zeitarbeit : Theoretische Analysen zu den Auswirkungen der Leiharbeit auf den Arbeitsmarkt
(2012) Pfleger, Stefan; Beißinger, Thomas
Since 1990 temporary agency work has increased rapidly in most western countries. Despite that fact, the academic research about this trend is still at the beginning. This dissertation contributes to the theoretical field of research by investigating the effects of the existence of temporary work agencies on the labor market. Using different kinds of matching-models, the analysis focuses on the identification of the growth-determinants of temporary agency work and the various kinds of effects that temporary agency work can have on the performance of the labor market. Chapter 2 gives an overview about the phenomenon ?temporary agency work?, its legal framework in Germany and the motives of firms and individuals, which use the services of temporary work agencies. In addition, some data of the structure and development of temporary agency work in Germany is presented. An introduction into (standard) matching-models of the labor market is given in chapters 3 to 5. Afterwards, the traditional matching-framework is used to analyze the intermediation-function of temporary work agencies. In Chapter 6 to 8 a modification of the traditional matching-framework is made by explicitly incorporating temporary agency work as an additional labor market segment. By doing so, it is possible to analyze the interaction with other kinds of labor market institutions, such as employment protection. The model presented in Chapter 6 investigates whether the deregulation of temporary agency work has contributed to its rapid growth. Furthermore it is discussed under which circumstances the expansion of the temporary work sector leads to the growding-out of regular jobs. Afterwards, an empirical analysis examines the effects of the deregulation process on the growth of temporary agency work in Germany. Chapter 7 shows that there are also factors outside the temporary work sector that can explain its growing importance. The model developed in this chapter is used to analyze the effects of firing-costs on the temporary work sector. Furthermore it is asked which effects the existence of the temporary work sector has on labor market performance when the regular sector becomes more rigid. The model developed in chapter 8 analyzes the wage-effects of temporary work. Initially, the analysis focuses on the effects of a change of the wage-differential between regular and temporary agency work. Finaly it is shown what effects the growth of the agency work sector can have on the wages of temporary and regular workers.
Neue Anforderungen an eine gesamtwirtschaftliche Stabilisierung
(2006) Beißinger, Thomas
In dieser Arbeit soll der Frage nachgegangen werden, wie sich das erneute Interesse an der Stabilisierung der Ökonomie durch Nachfragesteuerung erklären lässt und welche neuen Anforderungen an die Stabilisierungspolitik sich unter Umständen aus der aktuellen Forschung ableiten lassen. Dabei muss bereits vorab betont werden, dass es im Rahmen eines Aufsatzes unmöglich ist, diese Thematik in all ihren Facetten zu diskutieren und vielmehr nur einzelne Aspekte herausgegriffen werden können. In Abschnitt 2 werden zunächst mögliche Ursachen für die erneute Hinwendung zu Fragen der gesamtwirtschaftlichen Stabilisierung angeführt. Abschnitt 3 widmet sich der Frage, welche Wohlfahrtsgewinne durch eine verbesserte Stabilisierungspolitik zu erwarten sind. Da neuere Forschungsergebnisse auf beträchtliche Wohlfahrtsgewinne hindeuten, erscheint es lohnend, über neue Anforderungen an eine gesamtwirtschaftliche Stabilisierung nachzudenken. Abschnitt 4 widmet sich der Frage möglicher Verbesserungen einer auf Inflationssteuerung ausgerichteten Geldpolitik, während Abschnitt 5 Möglichkeiten und Grenzen fiskalpolitischer Maßnahmen zur Konjunkturstabilisierung anspricht. Abschnitt 6 schließt mit einer Zusammenfassung und einigen Schlussfolgerungen.
Real wages and the business cycle in Germany
(2010) Beißinger, Thomas; Marczak, Martyna
This paper establishes stylized facts about the cyclicality of real consumer wages and real producer wages in Germany. As detrending methods we apply the deterministic trend model, the Beveridge-Nelson decomposition, the Hodrick-Prescott filter, the Baxter-King filter and the structural time series model. The detrended data are analyzed both in the time domain and in the frequency domain. The great advantage of an analysis in the frequency domain is that it allows to assess the relative importance of particular frequencies for the behavior of real wages. In the time domain we find that both real wages display a procyclical pattern and lag behind the business cycle. In the frequency domain the consumer real wage lags behind the business cycle and shows an anticyclical behavior for shorter time periods, whereas for longer time spans a procyclical behavior can be observed. However, for the producer real wage the results in the frequency domain remain inconclusive.
