The effect of social security, demography and technology on retirement

This article investigates the causes in the reduction of labor force participation of the old. We argue that the changes in social security policy, in technology and in demography may account for most of the changes in retirement over the second part of the last century in the U.S. economy. We develop a dynamic general equilibrium model with endogenous retirement that embeds social security legislation. The model is able to match very closely the increase in the retirement rate of males aged 65 and older. It also quanti es the isolated impact on retirement and on the solvency of the social security system of the di¤erent factors. The model suggests that technological and demographic changes had a strong in uence on retirement, so that it would have increased signi cantly even if the social security rules had not changed. However, as the latter became much more generous in the past, changes in social security policy can account not only for a sizeable part of the expansion of retirement, but also for the most of the observed increase in the social security expenses as a share of GDP.

The effect of social security, health, demography and technology on retirement

This article studies the determinants of the labor force participation of the elderly and investigates the factors that may account for the increase in retirement in the second half of the last century. We develop a life-cycle general equilibrium model with endogenous retirement that embeds Social Security legislation and Medicare. Individuals are ex ante heterogeneous with respect to their preferences for leisure and face uncertainty about labor productivity, health status and out-of-pocket medical expenses. The model is calibrated to the U.S. economy in 2000 and is able to reproduce very closely the retirement behavior of the American population. It reproduces the peaks in the distribution of Social Security applications at ages 62 and 65 and the observed facts that low earners and unhealthy individuals retire earlier. It also matches very closely the increase in retirement from 1950 to 2000. Changes in Social Security policy - which became much more generous - and the introduction of Medicare account for most of the expansion of retirement. In contrast, the isolated impact of the increase in longevity was a delaying of retirement.

The life-cycle effects of social security in a model with housing and endogenous benefits

This article develops a life-cycle general equilibrium model with heterogeneous agents who make choices of nondurables consumption, investment in homeowned housing and labour supply. Agents retire from an specific age and receive Social Security benefits which are dependant on average past earnings. The model is calibrated, numerically solved and is able to match stylized U.S. aggregate statistics and to generate average life-cycle profiles of its decision variables consistent with data and literature. We also conduct an exercise of complete elimination of the Social Security system and compare its results with the benchmark economy. The results enable us to emphasize the importance of endogenous labour supply and benefits for agents' consumption-smoothing behaviour.

Incomplete contracts and the problem of social harm

We construct a model in which a first mover decides on its location before it knows the identity of the second mover; joint location results in a negative extemality. Contracts are inherently incomplete since the first mover's initial decision cannot be specified. We analyze several kinds of rights, including damages, injunctions, and rights to exclude (arising from covenants or land ownership). There are cases in which allocating any of these basic rights to the first mover-i.e., first-party rights-is dominated by second-party rights, and cases in which the reverse is true. A Coasian result (efficiency regardless of the rights allocation) only holds under a limited set of conditions. As corollaries of a theorem ranking the basic rights regimes, a number of results emerge contradicting conventional wisdom, including the relative inefficiency of concentrated land ownership and the relevance of the generator's identity. We conclude with a mechanism and a new rights regime that each yield the first best in all cases.

The impact on the stationary state income of a pay-as-you-go system of social security

A model of overlapping generations in continuous time is composed. IndividuaIs pass through two distinct time periods during their life times. During the first period, they work, save and have a death probability equal to zero. During the second, from the periods T after birth, their probability of death changes to p and then they retire. Capital stock and the stationary state in come are calculated for two situations: in the first, people live from their accumulated capital after retirementj in the second, they live from a state transfer payment through income taxo To simplify matters, in this preliminary version, it is supposed that there is no population growth and that the instantaneous elasticity substitution of consumption is unitary.

Formation of social capital in Eastern Europe : explaining the gap vis-à-vis developed countries

Recent Eurobarometer survey data are used to document and explain the leveI of social capital in thirteen new members and fifteen current members of the European Union. Social capital in Eastern Europe - measured by participation in clubs and organization, intensity of networks or altruistic behavior - lags behind that in developed countries. The differences in individual-leveI determinants cannot fully account for the gap at the aggregate leveI. Once we also include aggregate measures of economic development and quality of institutions, the gap disappears. This implies that the EU enlargement will contribute to a convergence in social capital, assuming that it contributes to the economic and institutional development of Eastern European countries. A necessary condition is that both, formal and informal institutions and their interaction should be regarded in this process.

The impact of social security reform on occupational and retirement behavior : a quantitative assessment for Brazil

Population ageing is a problem that countries will have to cope with within a few years. How would changes in the social security system affect individual behaviour? We develop a multi-sectoral life-cycle model with both retirement and occupational choices to evaluate what are the macroeconomic impacts of social security reforms. We calibrate the model to match 2011 Brazilian economy and perform a counterfactual exercise of the long-run impacts of a recently adopted reform. In 2013, the Brazilian government approximated the two segregated social security schemes, imposing a ceiling on public pensions. In the benchmark equilibrium, our modelling economy is able to reproduce the early retirement claiming, the agents' stationary distribution among sectors, as well as the social security deficit and the public job application decision. In the counterfactual exercise, we find a significant reduction of 55\% in the social security deficit, an increase of 1.94\% in capital-to-output ratio, with both output and capital growing, a delay in retirement claims of public workers and a modification in the structure of agents applying to the public sector job.

Contested dominance modifies the anovulatory consequences of social subordination in female marmosets

Dominance status among female marmosets is reflected in agonistic behavior and ovarian function. Socially dominant females receive submissive behavior from subordinates, while exhibiting normal ovulatory function. Subordinate females, however, receive agonistic behavior from dominants, while exhibiting reduced or absent ovulatory function. Such disparity in female fertility is not absolute, and groups with two breeding females have been described. The data reported here were obtained from 8 female-female pairs of captive female marmosets, each housed with a single unrelated male. Pairs were classified into two groups: “uncontested” dominance (UD) and “contested” dominance (CD), with 4 pairs each. Dominant females in UD pairs showed significantly higher frequencies (4.1) of agonism (piloerection, attack and chasing) than their subordinates (0.36), and agonistic behaviors were overall more frequently displayed by CD than by UD pairs. Subordinates in CD pairs exhibited more agonistic behavior (2.9) than subordinates in UD pairs (0.36), which displayed significantly more submissive (6.97) behaviors than their dominants (0.35). The data suggest that there is more than one kind of dominance relationship between female common marmosets. Assessment of progesterone levels showed that while subordinates in UD pairs appeared to be anovulatory, the degree of ovulatory disruption in subordinates of CD pairs was more varied and less complete. We suggest that such variation in female-female social dominance relationships and the associated variation in the degree and reliability of fertility suppression may explain variations of the reproductive condition of free-living groups of common marmosets

The trajectory of social housing policy in Brazil: From the National Housing Bank to the Ministry of the Cities

This paper discusses social housing policy in Brazil since the 1990s by analyzing government programs’ institutional arrangements, their sources of revenues and the formatting of related financial systems. The conclusion suggests that all these arrangements have not constituted a comprehensive housing policy with the clear aim of serving to enhance housing conditions in the country. Housing ‘policies’ since the 1990s – as proposed by Fernando Collor de Mello, Itamar Franco, Fernando Henrique Cardoso and ´ Luis Inacio Lula da Silva’s governments (in the latter case, despite much progress towards subsidized investment programs) – have sought to consolidate financial instruments in line with global markets, restructuring the way private interests operate within the system, a necessary however incomplete course of action. Different from rhetoric, this has resulted in failure as the more fundamental social results for the poor have not yet been achieved.

Sex Trade Involvement in São Paulo, Brazil and Toronto, Canada: Narratives of Social Exclusion and Fragmented Identities

An extensive international literature has been developed regarding the risk trajectories of sex trade-involved children and youth. This literature has not, however, substantially incorporated the narratives of youths regarding their experiences. In this article, the contemporary literature on child and youth sex trade-involvement is reviewed and the findings of a qualitative analysis of the narratives of 14 youth from São Paulo, Brazil and 58 youth from Toronto, Canada are presented. Substantial similarities were found between the groups of narratives with respect to abusive and unstable home experiences, pathways into the sex trade, social exclusion, and the impacts of the sex trade on physical and mental health. Key areas of divergence included the roles of poverty and drug use in entering the sex trade. The implications of shared experiences of social exclusion and fragmented identity across differing sociocultural contexts for policy and intervention are discussed.

As condições de trabalho na área de saúde e o processo de adoecimento da (o) assistente social

The requirements in the world of work in the contemporary impact on quality of life, health workers in their relations with users and other professionals of the healthcare team. Given this reality, this study discusses the working conditions in health and disease process of (a) having social goals as analyze the implications of working conditions in the disease (the) social workers in state hospitals Metropolitan Region Christmas (NMR); identify the main diseases affecting social workers in hospitals in the SESAP NMR and reveal the relationship between the disease processes of social and working conditions in hospitals in the state NMR. The research was guiding questions to reveal how to configure the work, conditions of work and of the disease process (the) social worker. To grasp the socioeconomic profile of (the) social workers, the characterization of the work, duties and responsibilities in the sociooccupational, factors that interfere with the disease process of (the) social workers of RMN, and actions and investments Policy on Occupational Health RN correlating to illness today is that we set for the unveiling of the movement of the object of study through the methodological approach with documentary research aimed at literature review; extensive direct observation correlated to real life observation and application of 66 (sixty-six) questionnaires. The data from the closed questions were treated using the Statistical Package for the Social Sciences (SPSS). The open questions were transcribed and then analyzed the light of theoretical work on the subject. The research reveals that social workers are subject to conditions and labor relations precarious illness causing health problems because some of these professionals, among them are: stress, allergies and skin conditions or, Read / WMSD among other diseases. Thus, we understand the need for debates about the relationship work (the) social worker and worker health before the contradictions of capital also present in public health services

Alcoholic women and men: a comparative study of social and familial aspects and outcome

Objetivos: A proporção de ocorrência de alcoolismo em homens e mulheres tem uma variação de 14:1 até 2:1, mostrando a necessidade de estudos específicos para a população feminina. O objetivo deste estudo foi analisar o perfil e a evolução de alcoolistas, segundo gênero e gravidade da dependência. Métodos: Realizou-se um estudo longitudinal retrospectivo de 114 homens e 57 mulheres alcoolistas (CID-10), inscritos no ambulatório da Faculdade de Medicina de Botucatu, no período de 1990-1994 e avaliados até julho de 1997. Utilizou-se um questionário semi-estruturado, e, para avaliação da gravidade do alcoolismo, o Short Alcohol Dependence Data. Resultados/Conclusões: Os principais resultados mostraram que a estrutura familiar estava comprometida com: relacionamento difícil para 55,6% das mulheres e 65,7% dos homens; violência familiar em 74,1% das mulheres e 61,1% dos homens. As mulheres iniciaram a ingestão mais tarde que os homens (p=0,01), em geral com seus cônjuges (p=0,00). Não houve diferença de evolução no tratamento entre os gêneros. Os principais fatores associados à melhor resposta ao tratamento, independentemente do sexo, foram: nível de gravidade de dependência do álcool (dependentes leves e moderados apresentaram 5,59 vezes mais chances de melhorar do que os dependentes graves); ser praticante de alguma religião (2,3 vezes mais chances de melhora do que os pacientes que não eram praticantes); e tempo de seguimento no programa, negativamente correlacionado a chances de melhora (0,68 vezes menos chances de melhora que aqueles que permaneceram por tempo menor em tratamento).
