Downward wage rigidity and business cycle asymmetries

The growth rates of wages, unemployment and output of a number of OECD countries have a strongly skewed distribution. In this paper we analyze to what extent downward wage rigidities can explain these empirical business cycle asymmetries. To this aim, we introduce asymmetric wage adjustment costs in a New-Keynesian DSGE model with search and matching frictions in the labor market. Increasing wages is less costly than cutting them. It follows that wages increase relatively fast and thus limit vacancy posting and employment creation, but they decline more slowly, leading to a strong reduction in vacancies and employment. The presence of downward wage rigidities strongly improves the fit of the model to the observed skewness of labor market variables and the relative length of expansions and contractions in the output and the employment cycles. The asymmetry also explains the differing transmission of positive and negative monetary policy shocks from wages to inflation.     

Occupational job creation: patterns and implications

This paper empirically investigates the matching process ofjob seekers and job vacancies, on different occupational labormarkets, and reveals the relative importance of supply and demandfactors, and frictions in the job creation process. Using datafrom German administrative records, we estimate matching functionsboth on the aggregate level, and for different occupationaland educational groups. The data allow to avoid some of theusual problems in empirical matching studies; extensive robustnessand stationarity tests are carried out. The results indicatesubstantial heterogeneity in the matching processes at disaggregatelevels. This information can be useful for policymakers, sincepolicy interventions that are effective in creating employmenton some occupational labor markets might lead to unsatisfactoryresults for other occupations.     

Job and vacancy competition in empirical matching functions

We investigate job competition among job seekers and vacancy competition among firms extending the job competition model proposed by Anderson and Burgess (Anderson, P.M., Burgess, S.M., 2000. Empirical matching functions: Estimation and interpretation using state level data. Review of Economics and Statistics 82, p. 90–102). Our results for data from West Germany provide evidence for both phenomena, thereby extending and qualifying previous insights.     

Identifying personality traits to enhance trust between organisations: an experimental approach

We investigate an experimental representatives' trust game which resembles trust relationships between representatives of organisations. Personality traits of subjects are elicited by a personality questionnaire (Cattell's 16 PF‐R) which is well established in personnel psychology. For the first time, personality traits are linked to actually observed behaviour in a trust game. Detailed personality profiles are derived and it is shown that they differ significantly between behavioural types. Individuals with low scores in anxiety turn out to be particularly qualified for enhancing trust between organisations. Copyright © 2008 John Wiley & Sons, Ltd.     

Im Spiegel der Anderen

The concept of social comparison is a core aspect of social psychology research and an important part of identity development, yet there has been little research on this phenomenon in the context of media usage. Combining different kinds of measurements, this study investigates the similarities and differences in social comparison to media characters versus persons from the social environment. A sample of 278 respondents answered a questionnaire about both kinds of comparison. Results indicate that persons from the social environment serve more often as comparison targets than media characters. Furthermore, media characters lead to an increased amount of upward comparison and to comparison with dissimilar others. The relevance of comparison dimensions seems to be independent of the comparison target.     

Spatial mobility and competition for jobs: Some theory and evidence for Western Germany

This paper sheds new light on the role of regional labor market conditions for regional mobility. We study competition for vacant jobs along two dimensions – between employed and unemployed job searchers, and between resident and non-resident job searchers – within a simple matching framework. Evidence from estimating regional matching functions with data on job searchers disaggregated by previous employment status and regional provenance indicates that competition for jobs along both dimensions affects hiring. Tests of the theoretical predictions suggest that labor market conditions do determine regional mobility, but the countervailing effects of competition between employed and unemployed dilute mobility effects.     

Did the Hartz Reforms Speed‐Up the Matching Process? A Macro‐Evaluation Using Empirical Matching Functions

Abstract. Starting in January 2003, Germany implemented the first two so-called Hartz reforms, followed by the third and fourth packages of Hartz reforms in January 2004 and January 2005, respectively. The aim of these reforms was to accelerate labor market flows and reduce unemployment duration. Without attempting to evaluate the specific components of these Hartz reforms, this paper provides a first attempt to evaluate the overall effectiveness of the first two reform waves, Hartz I/II and III, in speeding up the matching process between unemployed and vacant jobs. The analysis is conceptually rooted in the flow-based view underlying the reforms, estimating the structural features of the matching process. The results indicate that the reforms indeed had an impact in making the labor market more dynamic and accelerating the matching process.
