Evaluating the German (New Keynesian) Phillips Curve

North American Journal of Economics and Finance,
2010
Abstract
This paper evaluates the New Keynesian Phillips curve (NKPC) and its hybrid variant within a limited information framework for Germany. The main interest resides in the average frequency of price re-optimization by firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method based on the Anderson–Rubin statistic. We find that the German Phillips curve is purely forward-looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every 2–3 quarters. These estimates seem plausible from an economic point of view. But the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity, where firms never re-optimize prices. This analysis also offers some explanation as to why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way in which orthogonality conditions are formulated. Further, model mis-specifications may be left undetected by conventional J tests. This analysis points out the need for identification robust methods to get reliable estimates for the NKPC.

Change in East German Firm Level Export Determinants
Birgit Schultz
Wirtschaft im Wandel,
No. 3,
2010
Abstract
Exports have a ‘motor of growth’ status for the German economy. They both save and increase employment and provide wealth. However, only a minority of East German manufacturing and construction firms realize sales in foreign countries. The paper analyses for two points in time the influences of firm level export factors on the level of export activities of East German firms, and how the strength of the influence has changed over time. We found export sales especially in firms who are integrated in international corporate groups and are highly specialized. Economies of scale (firm size) increase the export share. Additionally, export sales also depend on wages. These findings are in line with current analysis in the field of international trade. While the above factors are found to be stable over time some others have changed in importance. In 2000 the industrial sector and the unit labor costs were important factors in determining export activities. In 2008 these factors have lost importance. Instead, human capital and investments have achieved significance.

Money and Inflation: The Role of Persistent Velocity Movements
Makram El-Shagi, Sebastian Giesen
Abstract
While the long run relation between money and inflation is well established, empirical evidence on the adjustment to the long run equilibrium is very heterogeneous. In the present paper we use a multivariate state space framework, that substantially expands the traditional vector error correction approach, to analyze the short run impact of money on prices. We contribute to the literature in three ways: First, we distinguish changes in velocity of money that are due to institutional developments and thus do not induce inflationary pressure, and changes that reflect transitory movements in money demand. This is achieved with a newly developed multivariate unobserved components decomposition. Second, we analyze whether the high volatility of the transmission from monetary pressure to inflation follows some structure, i.e., if the parameter regime can assumed to be constant. Finally, we use our model to illustrate the consequences of the monetary policy of the Fed that has been employed to mitigate the impact of the financial crisis, simulating different exit strategy scenarios.

Macroeconomic Shocks and Banks' Foreign Assets
Claudia M. Buch, K. Carstensen, A. Schertler
Journal of Money, Credit and Banking,
No. 1,
2010
Abstract
Recent developments in international financial markets have highlighted the role of banks in the transmission of shocks across borders. We employ dynamic panel methods for a sample of OECD countries to analyze whether banks' foreign assets react to macroeconomic shocks at home and abroad. We find that banks reduce their foreign assets in response to a relative increase in domestic interest rates, and they increase their foreign assets when the growth rate of world energy prices rises. The responses are characterized by a temporal overshooting and a dynamic adjustment process that extends over several quarters.

Monopsonistic Labour Markets and the Gender Pay Gap: Theory and Empirical Evidence
Boris Hirsch
Lecture Notes in Economics and Mathematical Systems,
No. 639,
2010
Abstract
This book investigates models of spatial and dynamic monopsony and their application to the persistent empirical regularity of the gender pay gap. Theoretically, the main conclusion is that employers possess more monopsony power over their female employees if women are less driven by pecuniary considerations in their choice of employers than men. Employers may exploit this to increase their profits at the detriment of women’s wages. Empirically, it is indeed found that women’s labour supply to the firm is less wage-elastic than men’s and that at least a third of the gender pay gap in the data investigated may result from employers engaging in monopsonistic discrimination. Therefore, a monopsonistic approach to gender discrimination in the labour market clearly contributes to the economic understanding of the gender pay gap. It not only provides an intuitively appealing explanation of the gap from standard economic reasoning, but it is also corroborated by empirical observation.

Subsidized Vocational Training: Stepping Stone or Trap? An Evaluation Study for East Germany
Eva Dettmann, Jutta Günther
IWH Discussion Papers,
No. 21,
2009
Abstract
The aim of this paper is to analyze whether the formally equal qualifications acquired during a subsidized vocational education induce equal employment opportunities compared to regular vocational training. Using replacement matching on the basis of a statistical distance function, we are able to control for selection effects resulting from different personal and profession-related characteristics, and thus, to identify an unbiased effect of the public support. Besides the ‘total effect’ of support, it is of special interest if the effect is stronger for subsidized youths in external training compared to persons in workplace-related training. The analysis is based on unique and very detailed data, the Youth Panel of the Halle Centre for Social Research (zsh).
The results show that young people who successfully completed a subsidized vocational education are disadvantaged regarding their employment opportunities even when controlling for personal and profession-related influences on the employment prospects. Besides a quantitative effect, the analysis shows that the graduates of subsidized training work in slightly worse (underqualified) and worse paid jobs than the adolescents in the reference group. The comparison of both types of subsidized vocational training, however, does not confirm the expected stronger effect for youths in external vocational education compared to workplace-related training.

Innovation and Skills from a Sectoral Perspective: A Linked Employer-Employee Analysis
Lutz Schneider, Jutta Günther, Bianca Brandenburg
Economics of Innovation and New Technology,
2010
Abstract
Science and engineering skills as well as management and leadership skills are often referred to as sources of innovative activities within companies. Broken down into sectoral innovation patterns, this article examines the role of formal education, actual occupation and work experience in the innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain information about corporate innovation activities and the qualification of employees in terms of formal education, actual professional status and work experience. We find clear differences in the human capital endowment between sectors according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in above average product innovation (specialized suppliers and science-based industries). However, according to our estimation results, across as well as within these sectors a large share of highly skilled employees does not substantially increase the probability of a firm being innovative.

Subsidized Vocational Education in East Germany: Stepping Stone or Dead End?
Eva Dettmann
Wirtschaft im Wandel,
No. 12,
2009
Abstract
The aim of the study is to analyse whether the formally equal qualifications acquired during a subsidized vocational education induce equal employment opportunities compared to regular vocational training. This question is answered for adolescents in workplace-related training. Using replacement matching on the basis of a statistical distance function, we are able to control for selection effects resulting from different personal and profession-related characteristics and thus to identify an unbiased effect of the public support. The analysis is based on unique, very detailed data, the Youth Panel of the Halle Centre for Social Research (zsh).
The results show that young people who successfully completed a workplace-related training are disadvantaged regarding their employment opportunities even when controlling for personal and profession-related influences. Besides a quantitative effect on the percentage of employed adolescents, the analysis shows differences in the job quality: The employed graduates of workplace-related training work in worse paid jobs, and less are employed in qualification adequate occupations compared to matchable graduates of regular vocational education.

From District Capital to State Capital: What are the Consequences of Rebuilding the East German States for the System of Cities?
Albrecht Kauffmann
Wirtschaft im Wandel,
No. 12,
2009
Abstract
20 years after the German unification, one may ask what consequences for the system of East German cities follow from the changes of the institutional framework. It may be expected that gains or losses of a location in the hierarchy of central places significantly affect the outcome of economic activity as well as the accumulation of – particularly human – capital. The reorganisation of countries on the territory of the former GDR that has elevated five former district capitals to the status of state capitals while the other ones became urban municipalities has created a model case whose implications were investigated by the IWH. The main objective was to identify a pattern of group formation within the former district capitals on the basis of socioeconomic indicators that coincides with the subgroups out of them with and without the status of a capital state. By means of cluster analysis, we have found that already from 1995 to 2000, differences between both groups with regard to income, structure of employment, human capital, and other indicators were significantly. In the period from 2002 to 2007, the spread of income is growing not only between both groups but also within the group of state capitals, dividing their cluster. We can conclude that the allocation of political institutions of higher centrality has influence on local economic development.
