El empleo informal y la estructura del mercado laboral en las regiones argentinas

El proceso de informalización del sector formal que se ha observado en América Latina durante los últimos años implica la coexistencia de trabajadores formales e informales que desarrollan sus actividades bajo diferentes condiciones laborales en el mismo sector. Sin embargo, la literatura, tanto empírica como teórica, le asignó tradicionalmente una estructura homogénea. No obstante, la segmentación del mercado laboral, particularmente del sector formal, tiene importantes consecuencias para el ingreso de los trabajadores y la movilidad ocupacional. El objetivo de este estudio es explorar, desde una perspectiva dinámica, el impacto de la informalidad en la estructura del mercado laboral argentino, investigando especialmente la hipótesis de segmentación del sector formal en las distintas regiones del país. Con ese fin, a partir de microdatos obtenidos de la Encuesta Permanente de Hogares (EPH), se estiman brechas salariales individuales y matrices de transición que permiten analizar los movimientos entre categorías ocupacionales definidas a partir de la condición de informalidad del trabajador y del sector en el que se desempeña. El resultado más relevante es la evidencia encontrada a favor de la segmentación del sector formal. La importancia de este hallazgo radica en sus implicaciones respecto de un grupo de trabajadores 'los asalariados no registrados' que no solo sufren una penalización en términos salariales sino que permanecen bajo condiciones laborales desfavorables asociadas con la informalidad

Trajetórias ocupacionais de engenheiros jovens no Brasil.

Esta tese analisa 9.041 trajetórias ocupacionais de jovens engenheiros como empregados formais no Brasil entre 2003-2012, a partir da técnica de Optimal Matching Analysis (OMA). Estas trajetórias foram comparadas às de uma geração anterior de jovens engenheiros, tanto em seu período-base (1995-2002) como entre 2003-2012, a fim de identificar efeitos de idade e período. Os principais resultados são: (i) conforme esperado, trajetórias ocupacionais ligadas à gestão (em áreas correlatas à engenharia ou não) são as que oferecem remuneração mais alta em todos os períodos analisados; (ii) nos anos 2000, o terceiro padrão mais atrativo para os jovens daquela geração foi permanecer como engenheiro típico, caminho perseguido por praticamente metade deles, enquanto tal atratividade não foi verificada nos anos 1990; (iii) o salário de entrada dos jovens engenheiros subiu 24% em termos reais entre 1995 e 2003; (iv) há pouca mobilidade de trajetória ocupacional por parte da geração dos engenheiros de 1995 após 2003; (v) os jovens engenheiros de 1995 que permaneceram como engenheiros típicos durante os anos 2000 chegaram a 2012 ganhando apenas 14% a mais do que os jovens engenheiros de 2003 (com 8 anos a menos de experiência); para comparação, os gestores da geração 90 ganhavam em torno de 50% a mais do que os da geração 2000; (vi) há dois momentos de definição de trajetória ocupacional: um primeiro ocorre até 3 anos após o primeiro emprego, mas promoções a cargos de gestão podem ocorrer entre 8 e 10 anos. Estes resultados indicam que, se por um lado houve uma revalorização dos profissionais de engenharia na última década, por outro lado esta revalorização não trouxe engenheiros anteriormente formados a carreiras típicas em engenharia. Isto, aliado à baixa demanda pelos cursos de engenharia durante os anos 80 e 90, corrobora a hipótese de um hiato geracional entre os engenheiros, documentado em artigos anteriores.

Late-career international migration and reproductive work. A comparison between Peruvian and Ukrainian women in the Southern Europe

Research on the relationship between reproductive work and women´s life trajectories including the experience of labour migration has mainly focused on the case of relatively young mothers who leave behind, or later re-join, their children. While it is true that most women migrate at a younger age, there are a significant number of cases of men and women who move abroad for labour purposes at a more advanced stage, undertaking a late-career migration. This is still an under-estimated and under-researched sub-field that uncovers a varied range of issues, including the global organization of reproductive work and the employment of migrant women as domestic workers late in their lives. By pooling the findings of two qualitative studies, this article focuses on Peruvian and Ukrainian women who seek employment in Spain and Italy when they are well into their forties, or older. A commonality the two groups of women share is that, independently of their level of education and professional experience, more often than not they end up as domestic and care workers. The article initially discusses the reasons for late-career female migration, taking into consideration the structural and personal determinants that have affected Peruvian and Ukrainian women’s careers in their countries of origin and settlement. After this, the focus is set on the characteristics of domestic employment at later life, on the impact on their current lives, including the transnational family organization, and on future labour and retirement prospects. Apart from an evaluation of objective working and living conditions, we discuss women’s personal impressions of being domestic workers in the context of their occupational experiences and family commitments. In this regard, women report varying levels of personal and professional satisfaction, as well as different patterns of continuity-discontinuity in their work and family lives, and of optimism towards the future. Divergences could be, to some extent, explained by the effect of migrants´ transnational social practices and policies of states.

Coexistence of stability and mobility in postural control: evidence from postural compensation for respiration

This study evaluated the extent to which movement of the lower limbs and pelvis may compensate for the disturbance to posture that results from respiratory movement of the thorax and abdomen. Motion of the neck, pelvis, leg and centre of pressure (COP) were recorded with high resolution in conjunction with electromyographic activity (EMG) of flexor and extensor muscles of the trunk and hip. Respiration was measured from ribcage motion. Subjects breathed quietly, and with increased volume due to hypercapnoca (as a result of breathing with increased dead-space) and a voluntary increase in respiration. Additional recordings were made during apnoea. The relationship between respiration and other parameters was measured from the correlation between data in the frequency domain (i.e. coherence) and from time-locked averages triggered from respiration. In quiet standing, small angular displacements (similar to0.5degrees) of the trunk and leg were identified in raw data. Correspondingly, there were peaks in the power spectra of the angular movements and EMG. While body movement and EMG were coherent with respiration (>0.5), the coherence between respiration and COP displacement was low (

(Endogenous) occupational choices and job satisfaction among recent PhD recipients: evidence from Catalonia

Drawing on data from two successive cohorts of PhD graduates, this paper analyses differences in overall job satisfaction and specific job domain satisfaction among PhDs employed in different sectors four years after completing their doctorate degrees. Covariate-adjusted job satisfaction differentials suggest that, compared to faculty members, PhD holders employed outside traditional academic and research jobs are more satisfied with the pecuniary facets of their work (principally, because of higher earnings), but significantly less satisfied with the content of their job and with how well the job matches their skills (and, in the case of public sector workers, with their prospects of promotion). The evidence regarding the overall job satisfaction of the PhD holders indicates that working in the public or private sectors is associated with less work well-being, which cannot be fully compensated by the better pecuniary facets of the job. It also appears that being employed in academia or in research centres provides almost the same perceived degree of satisfaction with the job and with its four specific domains. We also take into account the endogenous sorting of PhD holders into different occupations based on latent personal traits that might be related to job satisfaction. The selectivity-corrected job satisfaction differentials reveal the importance of self-selection based on unobservable traits, and confirm the existence of a certain penalisation for working in occupations other than academia or research, which is especially marked in the case of satisfaction with job content and job-skills match. The paper presents additional interesting evidence about the determinants of occupational choice among PhD holders, highlighting the relevance of certain academic attributes (especially PhD funding and pre-and-post-doc research mobility) in affecting the likelihood of being employed in academia, in a research centre or in other public or private sector job four years after completing their doctorate programme.

Health effects of occupational exposure to traffic particles and noise

Exposure to fine particles and noise has been linked to cardiovascular diseases and elevated cardiovascular mortality affecting the worldwide population. Residence and/or work in proximity to emission sources as for example road traffic leads to an elevated exposure and a higher risk for adverse health effects. Highway maintenance workers spend most of their work time in traffic and are exposed regularly to particles and noise. The aims of this thesis were to provide a better understanding of the workers' mixed exposure to particles and noise and to assess cardiopulmonary short term health effects in relation to this exposure. Exposure and health data were collected in collaboration with 8 maintenance centers of the Swiss Road Maintenance Services located in the cantons Bern, Fribourg and Vaud in western Switzerland. Repeated measurements with 18 subjects were conducted during 50 non-consecutive work shifts between Mai 2010 and February 2012, equally distributed over all seasons. In the first part of this thesis we tested and validated measurements of ultrafine particles with a miniature diffusion size classifier (miniDiSC) - a novel particle counting device that was used for the exposure assessment during highway maintenance work. We found that particle numbers and average particle size measured by the miniDiSC were highly correlated with data from the P-TRAK, a condensation particle counter (CPC), as well as from a scanning mobility particle sizer (SMPS). However, the miniDiSC measured significantly more particles than the P-TRAK and significantly less than the SMPS in its full size range. Our data suggests that the instrument specific cutoffs were the main reason for the different particle counts. The first main objective of this thesis was to investigate the exposure of highway maintenance workers to air pollutants and noise, in relation to the different maintenance activities. We have seen that the workers are regularly exposed to high particle and noise levels. This was a consequence of close proximity to highway traffic and the use of motorized working equipment such as brush cutters, chain saws, generators and pneumatic hammers during which the highest exposure levels occurred. Although exposure to air pollutants were not critical if compared to occupational exposure limits, the elevated exposure to particles and noise may lead to a higher risk for cardiovascular diseases in this worker population. The second main objective was to investigate cardiopulmonary short-term health effects in relation to the particle and noise exposure during highway maintenance work. We observed a PM2.5 related increase of the acute-phase inflammation markers C-reactive protein and serum amyloid A and a decrease of TNFa. Heart rate variability increased as a consequence of particle as well as noise exposure. Increased high frequency power indicated a stronger parasympathetic influence on the heart. Elevated noise levels during recreational time, after work, were related to increased blood pressure. Our data confirmed that highway maintenance workers are exposed to elevated levels of particles and noise as compared to the average population. This exposure poses a cardiovascular health risk and it is therefore important to make efforts to better protect the workers health. The use of cleaner machines during maintenance work would be a major step to improve the workers' situation. Furthermore, regulatory policies with the aim of reducing combustion and non-combustion emissions from road traffic are important for the protection of workers in traffic environments and the entire population.

Occupational choice and development

The rise in world trade since 1970 has been accompanied by a rise in the geographic span of control of management and, hence, also a rise in the e ective international mobility of labor services. We study the e ect of such a globalization of the world's labor markets. The world's welfare gains depend positively on the skill-heterogeneity of the world's labor force. We nd that when peoplecan choose between wage work and managerial work, the worldwide labor market raises output by more in the rich and the poor countries, and by less in the middle-income countries. This is because the middle-income countries experience the smallest change in the factor-price ratio, and where the option to choose between wage work and managerial work has the least value in the integratedeconomy. Our theory also establishes that after economic integration, the high skill countries see a disproportionate increase in managerial occupations. Using aggregate data on GDP, openness and occupations from 115 countries, we find evidence for these patterns of occupational choice.

Integrated Risk Management for Improving Internal Traffic Control, Work-Zone Safety, and Mobility during Major Construction, TPF-5(081), 2012

Highway construction is among the most dangerous industries in the US. Internal traffic control design, along with how construction equipment and vehicles interact with the traveling public, have a significant effect on how safe a highway construction work zone can be. An integrated approach was taken to research work-zone safety issues and mobility, including input from many personnel, ranging from roadway designers to construction laborers and equipment operators. The research team analyzed crash data from Iowa work-zone incident reports and Occupational Safety and Health Administration data for the industry in conjunction with the results of personal interviews, a targeted work-zone ingress and egress survey, and a work-zone pilot project.

Sector-Specific Training and Mobility in Germany

This article studies mobility patterns of German workers in light of a model of sector-specific human capital. Furthermore, I employ and describe little-used data on continuous on-the-job training occurring after apprenticeships. Results are presented describing the incidence and duration of continuous training. Continuous training is quite common, despite the high incidence of apprenticeships which precedes this part of a worker's career. Most previous studies have only distinguished between firm-specific and general human capital, usually concluding that training was general. Inconsistent with those conclusions, I show that German men are more likely to find a job within the same sector if they have received continuous training in that sector. These results are similar to those obtained for young U.S. workers, and suggest that sector-specific capital is an important feature of very different labor markets. In addition, they suggest that the observed effect of training on mobility is sensible to the state of the business cycle, indicating a more complex interaction between supply and demand that most theoretical models allow for.

A Gendered Triangle? Intergenerational Social Mobility in 20th Century Switzerland

In the light of the dramatically changed social structure of women, surprisingly little gender differences have been found in temporal changes of effects of social origin on occupational class. Using a recently developed methodological approach and Swiss data on birth cohorts from 1925 to 1978, this paper takes a closer look by considering not only the total effect of social origin but also the individual elements of the indirect effect mediated by individual’s education. It finds that this indirect path have changed indeed differently for women and men, but the findings on the direct effect remain mixed, partially because this path seems to be especially sensitive to the conceptualization of social class.
