A sequential model for older workers’ labor transitions after a health shock

In this work we study older workers (50 64) labor force transitions after a health/disability shock. We find that the probability of keeping working decreases with both age and severity of the shock. Moreover, we find strong interactions between age and severity in the 50 64 age range and none in the 30 49 age range. Regarding demographics we find that being female and married reduce the probability of keeping work. On the contrary, being main breadwinner, education and skill levels increase it. Interestingly, the effect of some demographics changes its sign when we look at transitions from inactivity to work. This is the case of being married or having a working spouse. Undoubtedly, leisure complementarities should play a role in the latter case. Since the data we use contains a very detailed information on disabilities, we are able to evaluate the marginal effect of each type of disability either in the probability of keeping working or in returning back to work. Some of these results may have strong policy implications.

Long-run substitutability between more and less educated workers: Evidence from U.S. States 1950-1990

We estimate the aggregate long-run elasticity of substitution between more and less educatedworkers (the slope of the demand curve for more relative to less educated workers) at theUS state level. Our data come from the (five)1950-1990 decennial censuses. Our empiricalapproach allows for state and time fixed effects and relies on time and state dependentchild labor and compulsory school attendance laws as instruments for (endogenous) changesin the relative supply of more educated workers. We find the aggregate long-run elasticity ofsubstitution between more and less educated workers to be around 1.5.

The effects of employment uncertainty and wealth shocks on the labor supply and claiming behavior of older American workers

Unemployment rates in developed countries have recently reached levels not seenin a generation, and workers of all ages are facing increasing probabilities of losingtheir jobs and considerable losses in accumulated assets. These events likely increasethe reliance that most older workers will have on public social insurance programs,exactly at a time that public finances are suffering from a large drop in contributions.Our paper explicitly accounts for employment uncertainty and unexpectedwealth shocks, something that has been relatively overlooked in the literature, butthat has grown in importance in recent years. Using administrative and householdlevel data we empirically characterize a life-cycle model of retirement and claimingdecisions in terms of the employment, wage, health, and mortality uncertainty facedby individuals. Our benchmark model explains with great accuracy the strikinglyhigh proportion of individuals who claim benefits exactly at the Early RetirementAge, while still explaining the increased claiming hazard at the Normal RetirementAge. We also discuss some policy experiments and their interplay with employmentuncertainty. Additionally, we analyze the effects of negative wealth shocks on thelabor supply and claiming decisions of older Americans. Our results can explainwhy early claiming has remained very high in the last years even as the early retirementpenalties have increased substantially compared with previous periods, andwhy labor force participation has remained quite high for older workers even in themidst of the worse employment crisis in decades.

Temporary help agencies and workers' occupational mobility

This paper focuses on the occupational mobility of temporary helpagency workers by studying their job-to-job upgrading chances as opposedto those who have not been hired through these intermediaries. A screeningapproach to the role of those labor brokers suggests that agency workersmay expect greater chances of upgrading from one occupation to another.Results obtained with a sample of Spanish workers show that workingthrough those intermediaries comparatively offers stronger prospects ofoccupational upgrading for workers of a medium qualification level. Thisbasic result is reinforced when the existence of self-selection into thistype of intermediated work is appropriately taken into account.

Retirement incentives, individual heterogeneity and labour transitions of employed and unemployed workers

In this paper we analyze the sensitivity of the labour market decisions of workers close toretirement with respect to the incentives created by public regulations. We improve upon the extensiveprior literature on the effect of pension incentives on retirement in two ways. First, bymodeling the transitions between employment, unemployment and retirement in a simultaneousmanner, paying special attention to the transition from unemployment to retirement (which is particularlyimportant in Spain). Second, by considering the influence of unobserved heterogeneity inthe estimation of the effect of our (carefully constructed) incentive variables.Using administrative data, we find that, when properly defined, economic incentives have astrong impact on labour market decisions in Spain. Unemployment regulations are shown to be particularlyinfluential for retirement behaviour, along with the more traditional determinants linked tothe pension system. Pension variables also have a major bearing on both workers reemploymentdecisions and on the strategic actions of employers. The quantitative impact of the incentives, however,is greatly affected by the existence of unobserved heterogeneity among workers. Its omissionleads to sizable biases in the assessment of the sensitivity to economic incentives, a finding thathas clear consequences for the credibility of any model-based policy analysis. We confirm theimportance of this potential problem in one especially interesting instance: the reform of earlyretirement provisions undertaken in Spain in 2002. We use a difference-in-difference approach tomeasure the behavioural reaction to this change, finding a large overestimation when unobservedheterogeneity is not taken into account.

Unemployment duration and workers' wage aspirations in Spain

This paper examines unemployed workers' declared willingness to work for a wage lower than the one warranted by their qualification. We analyze which personal and economic characteristics determine thiswillingness and how it changes as unemployment spells lengthen. Moreover, we also study the influence of this willingness on unemployment duration. The main results are: (i) Young workers, those less educated and those living in regions with high unemployment show a more positive attitude towards accepting lower wages while married women with a working husband show more negative attitudes; (ii) The exhaustion of unemployment benefits has positive effects in the transition probability of the attitude from negative to positive; (iii) The effect of this attitude on the unemployment hazard rate is positive but only marginally significant which may be showing that this willingness is not only reflecting the worker's reservation wage but also some unobserved heterogeneity; (iv) The negative duration dependence of the unemployment hazard rate is substantially reduced when unobserved heterogeneity is controlled for.

Foreign direct investments and spillovers through workers' mobility

We analyze a model where a multinational firm can use its superiortechnology in a foreign subsidiary only after appropriate trainingof local managers. Technological spillovers from foreign directinvestment arise when such managers are later hired by a localfirm. Benefits for the host economy may also take the form of therent that trained managers receive by the foreign affiliate toprevent them from moving to local competitors. We study conditionsunder which technological spillovers occur. We also show that undercertain circumstances the multinational firm might find it optimalto resort to export instead of foreign direct investment, to avoiddissipation of its intangible assets.

Workers' perception of workplace bullying: a cross-cultural study

This study is one of the first studies to approach workplace bullying cross-culturally. It sought to compare employees' understanding of workplace bullying in two different world regions: Central America and Southern Europe, regarding three aspects of workplace bullying: psychological vs. physical harassment, hierarchical vs. horizontal bullying, and direct vs. indirect aggression. A convenience sample of 246 workers provided their own definition of workplace bullying through a single, open-ended question. The results showed that employees from Central America emphasized the physical component of workplace bullying more than the Southern European employees. However, similarities in the conceptualization of workplace bullying across both cultures were found as well. Both Southern European and Central American employees defined workplace bullying mainly as a hierarchical phenomenon, where the aggression took the form of direct strategies. Such differences and similarities bring to the field some positive inputs for the development and implementation of different strategies for dealing effectively with this phenomenon.

Impact of the Spanish smoking control law on exposure to second-hand smoke and respiratory health in hospitality workers: a cohort study

A smoke-free law came into effect in Spain on 1st January 2006, affecting all enclosed workplaces except hospitality venues, whose proprietors can choose among totally a smoke-free policy, a partial restriction with designated smoking areas, or no restriction on smoking on the premises. We aimed to evaluate the impact of the law among hospitality workers by assessing second-hand smoke (SHS) exposure and the frequency of respiratory symptoms before and one year after the ban.

Job loss among immigrant and native workers: evidence from Spain's economic downturn

The profound crisis that has affected the Spanish economy since mid - 2008 has been characterized by significant job losses and a marked rise in the country´s unemployment rate. However, unemployment has had a differential impact on different population groups. Compared to native, immigrant workers have experienced higher rates of job loss. Against this backdrop, this paper examines the differences between immigrants and natives (distinguished by gender) in terms of their probability of suffering job loss in the downturn of late 2008 and 2009. Our results indicate that the higher rate of job loss among female immigrant workers can be fully explained by their lower endowment of human capital. By contrast, human capital endowment and over-representation in certain occupations, sectors and regions in which the crisis had greatest impact do not appear to be the only reason for the penalty suffered by immigrant males in terms of their chances of losing their job in the downturn.

Epigenetic alterations in hippocampus of SAMP8 senescent mice and modulation by voluntary physical exercise.

The senescence-accelerated SAMP8 mouse model displays features of cognitive decline and Alzheimer's disease. With the purpose of identifying potential epigenetic markers involved in aging and neurodegeneration, here we analyzed the expression of 84 mature miRNAs, the expression of histone-acetylation regulatory genes and the global histone acetylation in the hippocampus of 8-month-old SAMP8 mice, using SAMR1 mice as control. We also examined the modulation of these parameters by 8 weeks of voluntary exercise. Twenty-one miRNAs were differentially expressed between sedentary SAMP8 and SAMR1 mice and seven miRNAs were responsive to exercise in both strains. SAMP8 mice showed alterations in genes involved in protein acetylation homeostasis such as Sirt1 and Hdac6 and modulation of Hdac3 and Hdac5 gene expression by exercise. Global histone H3 acetylation levels were reduced in SAMP8 compared with SAMR1 mice and reached control levels in response to exercise. In sum, data presented here provide new candidate epigenetic markers for aging and neurodegeneration and suggest that exercise training may prevent or delay some epigenetic alterations associated with accelerated aging.

Kinship foster care: a study from the perspective of the of the caregivers, the children and the child welfare workers

In the last twenty years, in most Western countries, kinship foster care has become an integral part of childcare systems,growing progressively with regard to the numbers of children involved and relative weight as a care resource within thesystem; indeed, in some countries it is even more common than other placement options, such as non-kinship foster careand residential care. Research on this phenomenon is still recent and scarce, and there are few programmes targeting thispopulation. In this article we present the results of a descriptive study on kinship foster care in the city of Barcelona,including information and data from the different stakeholders involved. From a quality of life research perspective weanalyze the perceptions, evaluation and expressed satisfaction of caregivers, children and practitioners from the specialistChild and Adolescent Teams (EAIAs) responsible for the study and follow-up of kinship foster care cases. The researchpresented results are in line with those of current research in this field, and lays the basis for the future development ofkinship foster care programmes

Acogimiento en familia extensa: un estudio desde la perspectiva de los acogedores, de los niños y niñas acogidos y de los profesionales que intervienen. = Kinship foster care: a study from the perspective of the caregivers, the children and the child welfare workers

Desde hace aproximadamente dos décadas, en la mayoría de los países occidentales, los acogimientos en familia extensa han entrado a formar parte de los sistemas de protección infantil, siguiendo una evolución creciente en cuanto a número y peso especifico como recurso de acogimiento. Las investigaciones sobre este fenómeno son aún recientes y escasas como también lo son los programas dirigidos a esta población. En el presente artículo presentamos los resultados de un estudio descriptivo sobre los acogimientos en familia extensa en la ciudad de Barcelona, donde se recogen datos de los principales agentes implicados en este fenómeno. Desde la perspectiva de los estudios de la calidad de vida se analizan las percepciones, evaluaciones, y satisfacción expresada, por parte de los acogedores, los niños/as acogidos y los profesionales de los Equipos de Atención a la Infancia y Adolescencia (EAIA) que se encargan del estudio y seguimiento de estos acogimientos. La investigación presenta unos resultados acordes con los estudios que actualmente se realizan en este ámbito y sienta las bases para el despliegue futuro de programas dirigidos a los acogimientos en familia extensa
