Die Arbeit zeigt im Rahmen einer theoretischen Analyse, einer Institutionenanalyse und einer empirischen Einstellungsanalyse, welche normativen Konzepte von Gerechtigkeit in der Alterssicherung relevant sind, wie vor diesem Hintergrund bestimmte institutionelle Regelungen zu bewerten sind und welche Einstellungen in der deutschen Bevölkerung dazu vorliegen. Zunächst wird dargelegt, dass es kein a priori vollständig überzeugendes Konzept von Generationengerechtigkeit gibt. Insbesondere auf Generational-Equity basierende Ansätze, die suggerieren das Problem intergenerationaler Gerechtigkeit in der Rentenversicherung finanzmathematisch lösen zu können, muss mit Skepsis begegnet werden. Aufgrund theoretischer Überlegungen vorzuziehen sind hybride Konzepte, die sowohl universalistische als auch kultur- und demo-sensitive Aspekte in sich vereinen. Die Institutionenanalyse erbringt weiter, dass das zentrale mit Generationengerechtigkeit verknüpfte Problem weniger die Ungleichheit zwischen Generationen hinsichtlich ihrer durchschnittlichen Güterausstattung ist, sondern die in der Generationenfolge zunehmende intragenerationale Ungleichheit. Schließlich zeigt die empirische Analyse der Gerechtigkeitseinstellungen, dass Statussicherung bei den Renten wichtiger einzuschätzen ist als Beitragsäquivalenz. Die primären Vorstellungen von Gerechtigkeit in der Alterssicherung orientieren sich stark am institutionellen Status quo und kaum an abstrakten Generational-Equity-Konzepten, die die in der Bevölkerung verbreitete Verlustaversion vernachlässigen. Urteilsheuristiken und regimespezifische Sozialisation erklären dabei insgesamt mehr Variation als partikulare ökonomische oder altersspezifische Interessen. Die Probleme des Rentensystems im Zuge des demografischen Wandels werden gleichwohl gesehen, wobei Lösungsansätze eher in der Familien- und Bildungspolitik gesucht werden, während Reformen im bestehenden Rentensystem Ungerechtigkeitsgefühle kurzfristig sogar verstärken. / This thesis demonstrates by theoretical, institutional and empirical analysis, which justice concepts are relevant in old-age provision, how specific institutional arrangements have to be evaluated in this context and which justice attitudes on that matter exist in the German population. Firstly, there is no a priori convincing theoretical concept of generational justice. Especially concepts based on generational equity that propose to solve the problem of intergenerational justice in old-age provision by generational accounting methods have to be considered with skepticism. For theoretical reasons, hybrid concepts that encompass universalistic as well as culture- and demo-sensitive aspects should be preferred. Institutional analysis shows furthermore that the central problem connected to generational justice has less to do with inequality between generations and more with growing inequality within cohorts in the generational succession. Finally, the empirical analysis of justice attitudes provides evidence for the relative priority of status conservation over input-equity in the determination of just old-age benefits. Primary notions of justice in old-age provision are strongly anchored in the institutional status quo and only marginally influenced by abstract generational equity concepts that also neglect widespread loss aversion among individuals. Heuristics and regime-specific socialization explain more variation in justice attitudes than particularistic economic or age-specific interests do. The general public does not neglect the problems of pension-systems in the wake of demographic changes however, but solutions are rather seen in family and education policies, while reforms in existing pension arrangements even amplify feelings of injustice in the short run.

Establishing retirement age is a key issue for each and every pension system. How this issue is resolved is palpable for every citizen and also has a major political dimension. The main reasons for increasing the retirement age - which is occurring in all European countries - are demographic development and economic factors, such as higher life expectancy, increasing the proportion of pensioners to the number of economically active people, and the growing costs for the pension system. This thesis describes the current reform steps in Europe and provides a thorough analysis of factors which are relevant for dealing with retirement age issues. The analysis is based on official statistical data, which are scrutinized even in mutual correlations. The need for an interdisciplinary approach which eliminates unilateral vistas and biased application of data lifted out of context and long-term trends is emphasized. Special attention is paid to the genesis and current solutions regarding the retirement age in the Czech Republic. This thesis offers reasoning which supports setting 65 years of age as the statutory retirement age, including the mechanism for increasing it depending on how the life expectancy factor develops. How the retirement age issues are dealt with is based on the fundamental ethical...

JUDr. Ing. Miloslav Kaše, CSc., Selected Aspects of Pension Reform in the Czech Re- public, Doctoral Thesis, Charles University, Faculty of Law, Department of Labor Law and Social Security Law, Prague, 2020. Number of pages of doctoral thesis is 205. The dissertation topic evolves around certain selected aspects of the pension reform in the Czech Republic, which is the most discussed in the preparation phase of the Czech pension system reform. The chosen topic acknowledges the current problems of the Czech pension system, consisting mainly of the unfavorable development of demographic struc- ture and population aging, which is characterized by a large and irregular number of peaks and troughs on the demographic chart of the Czech Republic, connected to historical events and migration. The thesis focuses on the issue of developing and determining the retirement age and insurance coverage required for entitlement to pension and analyzes the pitfalls of increas- ing the retirement age and the length of insurance coverage required to qualify for a retirement pension. At the same time, it considers the possibilities of establishing an ad- justable retirement age range and flexibility of the whole pension system. The possibility of active economic earning vitality of pensioners is closely related to the...
