The political economy of social security: A survey
No full textThis paper surveys the literature on the political economy of social security. We review models that address the following questions: (i) Why do social security programs that transfer resources from young and middle-aged workers to the elderly exist? (ii) What are the economic and political interactions between social security systems and other redistributive programs of the welfare state? (iii) How does political sustainability shape social security systems in a dynamic economic and demographic environment, and which social security reforms are politically feasible? We characterize this literature along two lines: economic factors and political institutions. We then assess the empirical relevance of the models by comparing their implications to stylized social security facts. © 2002 Elsevier Science B.V. All rights reserved
A further comment on ageing and the welfare state
No full textThis symposium was initiated as a forum for discussion of issues about ageing and the welfare state stemming from the paper by Razin, Sadka, and Swagel, "The ageing population and the size of the welfare state", which appeared in the Journal of Political Economy in 2002 (vol. 110 (4) pp. 900-918). We here comment on the contribution of Razin and Sadka to the symposium. © 2006 Elsevier B.V. All rights reserved

Annuity puzzle: Evidence from a Swiss pension fund
Full text linkWe analyze individual annuitization decisions at retirement in an environment with mandatory participation in a funded pension pillar and low average annuity price. Using administrative data from a large Swiss insurance company over the period 2011–2015, we document that, even in this favorable environment, only 42.7% of the retirees fully annuitize, against 45% taking full lump sum. We show that individual annuitization decisions strongly respond to financial incentives, measured by the Money Worth Ratio, and to the tax rates on annuity and lump-sum payments. Lump-sum payments are more common among French- and Italian-speaking individuals. Using Survey of Health, Ageing and Retirement in Europe data, we show that French- and Italian-speaking Swiss are more likely to leave inheritance—thus suggesting that preferences for bequests may affect annuitization decisions. Finally, we provide evidence of asymmetric information, using the unused observable test, to show that individuals living in high mortality municipalities are less likely to annuitize and more likely to cash out their pension wealth
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Il Mercato Del Lavoro Dei Politici
No full textLe classi dirigenti hanno una funzione importante nelle nostre società. Rendono possibili obiettivi altrimenti irraggiungibili, rimuovendo gli ostacoli che inibiscono la crescita nel lungo periodo. Ma come si formano? Come vengono selezionate? Gli strumenti dell’economia del lavoro, in particolare, sono molto utili per mettere a fuoco i meccanismi di selezione delle élite, per analizzare il mercato del lavoro dei politici o gli incentivi, i redditi, l’uso del tempo e la struttura delle carriere dei manager. Il libro offre un contributo originale e colma una lacuna in termini di dati oggettivi
