Social Security, Education, Retirement and Growth

In this paper we analyze the effects of social security policies in an unfunded, earnings-related social security system on the incentives to education investment and voluntary retirement, on growth and on income inequality. Growth is endogenously driven by human capital investment, individuals differ in their innate (learning) ability at birth, and the pension scheme includes a minimum pension. More skilled individuals spend more on education, minimum pensions reduce low skill individuals' incentives to invest in human capital, there is no monotonic relationship between per capita growth and income inequality.

Democratic Values Transmission

This study addresses the issue of intergenerational transmission of democratic values embedded in social choice rules. We focus on a few rules which have been the focus of social choice theory: plurality, plurality with a runoff, majoritarian compromise, social compromise and Borda rule. We confront subjects with preferences profiles of a hypothetical electorate over a set of four alternatives. Different rules produce different outcomes and subjects decide which alternative should be chosen for the society whose preference profile is shown. We elicit each subject's preferences over rules and his/her parents' and check whether there is any relationship; 186 students and their parents attended the sessions at Istanbul Bilgi University. Overall, we find support for the hypothesis of parental transmission of democratic values and gender differences in the transmitted rule.

Subjektu egozgarri eta arriskutsuen tratamendu penala

[ES]El presente Trabajo de Fin de Grado analiza el tratamiento penal de los sujetos imputables peligrosos que mantienen la peligrosidad criminal tras el cumplimiento de la pena de prisión. De esta manera, se investiga la regulación jurídica española dirigida a este colectivo, poniendo de manifiesto que hasta la entrada en vigor de la Ley Orgánica 5/2010 de reforma del Código Penal no había prevista ninguna medida de seguridad enfocada a este grupo específico y concluyendo que la medida de “libertad vigilada” introducida en dicha reforma no es del todo efectiva para alcanzar la reinserción del reo. Por todo ello, se argumenta que la política criminal llevada a cabo en los últimos años ha llevado la seguridad a un extremo tal que no se han podido garantizar del todo los derechos individuales del colectivo anteriormente mencionado. Asimismo, se investiga la “custodia de seguridad” vigente en la regulación alemana, haciendo notoria la importancia de la seguridad e inocuización. En síntesis, se estudia si el delincuente ha quedado subordinado al orden jurídico y a la seguridad, esclareciendo si han sido respetados los principios y garantías inherentes a un Estado Social y Democrático de Derecho.
