The Anatomy of Absenteeism

Based on comprehensive administrative register data from Norway, we examine the determinants of sickness absence behavior; in terms of employee characteristics workplace characteristics, panel doctor characteristics, and economic conditions. The analysis is based on a novel concept of a worker's steady state sickness absence propensity, computed from a multivariate hazard rate model designed to predict the incidence and the duration of sickness absence for all workers. Key conclusions are i) that most of the cross-sectional variation in absenteeism is caused by genuine employee heterogeneity; ii) that the identity of a person's panel doctor has a significant impact on absence propensity; iii) that sickness absence insurance is frequently certified for reasons other than sickness; and iv) that the recovery rate rises enormously just prior to the exhaustion of sickness insurance benefits.sickness absence, multivariate hazards, MMPH, NPMLE

Pobreza, Deforestación y Pérdida de la Biodiversidad en Guatemala

This paper explores the causes of deforestation and biodiversity loss in Guatemala and is organized into 4 parts. First, an overview about deforestation in Guatemala from 1950-2000 is provided, and the relationship between deforestation and biodiversity loss is explored. Secondly, some underlying causes of deforestation are examined. While caution is needed about many conventional hypotheses, there are strong reasons to believe that higher rural wages generated by greater off-farm employment opportunities reduce deforestation. Thirdly, an empirical analysis indicates that agricultural activities in rural areas remain closely tied to deforestation because of the virtual absence of non- environmental assets of the poor. And finally, some doubts are placed on the excessive establishment of Integrated Conservation and Development Projects (ICDPs) within the countryside. In particular, the paper concludes that for the case of Guatemala strengthening the rural non- farm sector and human capital formation should be regarded as a key elements of a development strategy that tries to combine biodiversity conservation within a framework of sustainable economic growth and poverty alleviation. El presente trabajo explora las causas de la deforestación y la pérdida de la biodiversidad en Guatemala. El documento se divide en cuatro partes. En la primera parte, se presenta una generalización sobre la deforestación en Guatemala entre 1950-2000. Así mismo, se explora la relación entre la deforestación y la pérdida de la biodiversidad. En la segunda parte, se examinan algunas de las causas de la deforestación. Aunque es necesario analizar con cuidado algunas de las hipótesis convencionales, hay razones sólidas para creer que mayores salarios rurales generados por mejores opciones de empleo no agrícola reducen la deforestación. En la tercera parte, se realiza un análisis empírico, el cual indica que las actividades agrícolas en las áreas rurales están fuertemente relacionadas a la deforestación debido a la ausencia de activos no ambientales de los pobres, como por ejemplo la educación. Finalmente, se plantean algunas dudas sobre el establecimiento excesivo de áreas protegidas dentro del país. En particular, el trabajo concluye que el fortalecimiento del sector rural no agrícola y la formación de capital humano deberían tomarse como elementos claves para una estrategia de desarrollo que intente combinar conservación de la biodiversidad con crecimiento económico sostenible y reducción de la pobreza.Biodiversity, Deforestation, Econometrics, Education, Integrated Conservation and Development Projects, Poverty, Rural Non- farm Employment, Guatemala, Biodiversidad, Deforestación, Econometría, Educación, Areas protegidas, Pobreza, Empleo rural no agrícola

The changing of the guards: Can physicians contain social insurance costs?

Based on administrative data from Norway, we examine the extent to which family doctors influence their clients' propensity to claim sick pay and disability benefits. The analysis is based on exogenous shifts of family doctors occurring when physicians quit, retire, or for other reasons sell their patient lists to other doctors. Our key finding is that family doctors have significant influence on their clients' benefit claims. We conclude that it is possible for family doctors to contain social insurance costs to some extent, and that there is a significant variation across doctors in the way they do so

Ab initio vibrations in nonequilibrium nanowires

We review recent results on electronic and thermal transport in two different quasi one-dimensional systems: Silicon nanowires (SiNW) and atomic gold chains. For SiNW's we compute the ballistic electronic and thermal transport properties on equal footing, allowing us to make quantitative predictions for the thermoelectric properties, while for the atomic gold chains we evaluate microscopically the damping of the vibrations, due to the coupling of the chain atoms to the modes in the bulk contacts. Both approaches are based on a combination of density-functional theory, and nonequilibrium Green's functions.Comment: 16 pages, to appear in Progress in Nonequilibrium Green's Functions IV (PNGF4), Eds.
