The internal labor marketsof business groups
This paper provides micro evidence of labor mobility inside business groups. We show that worker flows between firms in the same group are stronger than with unaffiliated firms. More over, the reallocation of top workers between group firms is more sensitive to international shocks. Top workers that move within the group in response to shocks […]
The fertility-inhibiting effect of mosquitoes: Socio-economic differences in response to the Zika crisis in Colombia
We estimated the impact of the Zika virus outbreak on birth rates and demand for health care services in Colombia. Our analysis exploits the variation in the level of natural protection against mosquito transmitted diseases across the country. This characteristic induced exogenous variation in Zika incidence, which allows us to construct a control group of […]
Price elasticity of demandfor voluntary health insurance plans in Colombia
Background: Since 1993, Colombia has had a mandatory social health insurance scheme that aims to provide universal health coverage to all citizens. However, some contributory regime participants purchase voluntary private health insurance (VPHI) to access better quality health services (i. e., physicians and hospitals), shorter waiting times, and a more extensive providers’ network. This article […]
Human capital, innovationand productivity in Colombian enterprises: astructural approach usinginstrumental variables
In this paper we explore the R&D–innovation–productivity linkage for the Colombian manufacturing industry, paying special attention to the role of human capital. Using data from two firm-level surveys, the Survey of Development and Technological Innovation (EDIT) and the Annual Manufacturing Survey (EAM), we extend the model of Crépon, Duguet, and Mairesse [1998. ‘Research, Innovation and […]
Conexiones y capital socialo por qué la información devacantes no llega a quienesla necesitan
Resumen Entre un 50% y un 60% de los trabajadores encuentran empleo con información que proporcionan amigos, familiares o conocidos. En una simulación en red, estudiamos cómo evoluciona el número de trayectorias por las que se transfiere información sobre vacantes cuando se suma un nuevo nodo, teniendo en cuenta su estatus laboral, su capital social […]
Bounded learning by doing,inequality, and multi-sectorgrowth: A middle-class perspective.
This paper develops a multi-sector model of middle-class-led economic growth, whereby (i) learning by doing interacts with scale economies and nonhomothetic preferences giving rise to endogenous growth, and (ii) the “middle class” label is an endogenous outcome of the model, depending on past economic growth. The emphasis is placed on the entire income distribution, which […]
Crime and education in a model of information transmission
We model the decisions of young individuals to stay in school or drop out and engage in criminal activities. We build on the literature on human capital and crime engagement and use the framework of Banerjee (1993) that assumes that the information needed to engage in crime arrives in the form of a rumour and […]
Kangaroo mother care had a protective effect on the volume of brain structures in young adults born preterm
Aim: The protective effects of Kangaroo mother care (KMC) on the neurodevelop-ment of preterm infants are well established, but we do not know whether the ben-efits persist beyond infancy. Our aim was to determine whether providing KMC in infancy affected brain volumes in young adulthood.Method: Standardised cognitive, memory and motor skills tests were used to deter-mine the […]
The daily grind: Cash needs and labor supply
The majority of people in developing countries are self-employed and can therefore set their own work hours. How do self-employed individuals motivate themselves to work hard day after day? We document four facts about the labor supply of Kenyan bicycle-taxi drivers: (1) drivers work more on days with higher cash needs; and (2) the quitting […]
The gradient allocation principle based on the higher moment risk measure
According to the gradient allocation principle based on a positively homogeneous and subadditive risk measure, the capital allocated to a sub-portfolio is the Gâteaux derivative, assuming it exists, of the underlying risk measure at the overall portfolio in the direction of the sub-portfolio. We consider the capital allocation problem based on the higher moment risk […]
