competition and the possibilities to finance the pension payments with less anti-incentive effects. However, the implications on the income distribution are ignored in most cases. In this paper effects of a changing contribution base for employer payments on the functional and on the personal income distribution are analysed. Inflationary and regressive effects are to be expected by such a change of the computation base for employer contributions. In addition effects of income redistribution within the retirement system are analysed. The degree of interpersonal income redistribution will increase and of intertemporal income redistribution will decrease. The German retirement system will become less of an insurance system and more of a tax-transfer system. At the same time the degree of the protection of property for pension claims by the constitution would be lowered. The possibilities of interventions by parliament and government in pension claims will increase. These effects can lower the acceptance of the social security retirement system. Author's Abstract

Goethe-Universitaet Frankfurt und Universitaet Mannheim, FRG (1983). In this paper, two concepts of explaining and forecasting disaggregated labor-demand in groups of qualifications are discussed: a recursive link of models as an extension of the classical 'manpower-requirement approach' and the specification of econometric labor-demand functions. The problems of finding appropriate indicators for qualifications and constructing a database are shown in detail. In a first empirical investigation it is tried to discover important reasons for the demand for qualifications in different industrial sectors, disaggregated by 'Leistungsgruppen', and sex. As a main result in this paper it is shown that the impacts of production, productivity, and the costs of labor and capital are significantly different for particular groups of labor force.

Winfried Sclunael, Income analysis based on longitudinal data from social security earnings records: The relative earnings position (age-earnings profile) and the individual replacement rate of German workers, AP Nr. 92, Sonderforsehungsbereich 3, J.W. Goethe-Universitaet Frankfurt und Universitaet Mannheim, FRG (1983). In this paper some possibilities of longitudinal data based on earnings records of the German Social Security Administration (retirement system) for income analysis are discussed. First a short description of the data base is given. Then it is discussed whether there exists an inverse u-shaped age-earnings profile for German workers as is often found on the basis of cross-sectional data. The longitudinal data show another picture of earnings development during worklife. The inverse u-shape of the age-earnings profile seems to be to a high degree the result of structural differences between the birth cohorts. Then some information are given on the earnings replacement :a|e of the German retirement system for different groups of workers. Author's Abstract
