Is child labor harmful? the impact of working as a child on adult earnings

This paper explores the question: is working as young laborer harmful to an individual in terms of adult outcomes in income? This question is explored through the utilization of a unique set of instruments that control for the decision to work as a child and the decision of how much schooling to acquire. These instruments are combined with two large household survey data sets from Brazil that include retrospective information on the child labor and schooling of working-age adults: the 1988 and 1996 PNAD. Estimations of the reduced form earnings model are performed first by using OLS without controlling for the potential endogeneity of child labor and schooling, and then by using a GMM estimation of instrumental variables models that include the set of instruments for child labor and schooling. The findings of the empirical investigations show that child labor has large negative impact on adult earnings for both male and female children even when controlling for schooling. In addition, the negative impact of starting to work as a child reverses at around age 14. Finally, different child labor activities are examined to determine if some are beneficial while others harmful with the finding that working in agriculture as a child appears to have no negative impact over and above the loss of education.

Wealth composition, endogenous fertility and the dynamics of income inequality

This paper analyzes how differences in the composition of wealth between human and physical capital among families affect fertility choices. These in tum influence the dynamics of wealth and income inequality across generations through a tradeoffbetween quantity and quality of children. Wealth composition affects fertility because physical capital has only a wealth effect on number of children, whereas human capital increases the time cost of child-rearing in addition to the wealth effect. I construct a model combining endogenous fertility with borrowing constraints in human capital investments, in which weaIth composition is determined endogenously. The model is calibrated to the PNAD, a Brazilian household survey, and the main findings of the paper can be summarized as follows. First, the model implies that the crosssection relationship between fertility and wealth typically displays a U-shaped pattem, reflecting differences in wealth composition between poor and rich families. Also, the quantity-quality tradeoff implies a concave cross-section relationship between investments per child and wealth. Second, as the economy develops and families overcome their bOlTowing constraints, the negative effect of weaIth on fertility becomes smaller, and persistence of inequality declines accordingly. The empirical evidence presented in this paper is consistent with both implications .

Mercado de trabalho e estrutura sócio-ocupacional: estudo comparativo entre as regiões metropolitanas de Fortaleza, Recife e Salvador 2001-2008

The economic transformations in the world, the end of World War II, listing significant changes in production structures and labor market in the world. Initially developed countries realize these changes and subsequently developing countries. The changes in production patterns, especially with the crisis of Fordism, peripheral countries further accentuated the problems in the workplace. Flexible accumulation, in turn, was responsible for significant changes in the labor market at the periphery of global capitalism. This restructuring process, in Brazil, begun from the end of the 1980s and early 1990s, being more accentuated the impacts on the labor market in the poorest regions of the country, particularly the Northeast. In that sense, this thesis aims to evaluate the job market in the metropolitan areas of Fortaleza, Recife and Salvador in light of the transformation process in the production structures and labor market and its influences in the 2000s. The time frame are the years 2001-2008. Data are from the National Household Sample Survey - PNAD and were drawn from the study proposal developed by the Centre of the Metropolis. The study shows that the labor market of the three metropolitan areas continues to be affected by the restructuring process of the late twentieth century. It found high rates of unprotected busy at work is more precarious conditions of employment for non-whites, women, adolescents / young and old. We also highlight the high percentage of employed persons earning income up 1.00 minimum wage, and a large number of persons employed in the tertiary and tertiary non-specialist. With the picture observed in the three metropolitan areas you can see the major problems in the labor market that proliferate, especially in the metropolitan context of the Northeast, with characteristics similar to those observed in the literature that investigated the labor market in 1990

Role of the bed nucleus of the stria terminalis in cardiovascular changes following chronic treatment with cocaine and testosterone: A role beyond drug seeking in addiction?

Neural plasticity has been observed in the bed nucleus of the stria terminalis (BNST) following exposure to both cocaine and androgenic-anabolic steroids. Here we investigated the involvement of the BNST on changes in cardiovascular function and baroreflex activity following either single or combined administration of cocaine and testosterone for 10 consecutive days in rats. Single administration of testosterone increased values of arterial pressure, evoked rest bradycardia and reduced baroreflex-mediated bradycardia. These effects of testosterone were not affected by BNST inactivation caused by local bilateral microinjections of the nonselective synaptic blocker CoCl2. The single administration of cocaine as well as the combined treatment with testosterone and cocaine increased both bradycardiac and tachycardiac responses of the baroreflex. Cocaine-evoked baroreflex changes were totally reversed after BNST inactivation. However, BNST inhibition in animals subjected to combined treatment with cocaine and testosterone reversed only the increase in reflex tachycardia, whereas facilitation of reflex bradycardia was not affected by local BNST treatment with CoCl2. In conclusion, the present study provides the first direct evidence that the BNST play a role in cardiovascular changes associated with drug abuse. Our findings suggest that alterations in cardiovascular function following subchronic exposure to cocaine are mediated by neural plasticity in the BNST. The single treatment with cocaine and the combined administration of testosterone and cocaine had similar effects on baroreflex activity, however the association with testosterone inhibited cocaine-induced changes in the BNST control of reflex bradycardia. Testosterone-induced cardiovascular changes seem to be independent of the BNST. © 2013 IBRO.

Report of the regional workshop on microdata documentation and dissemination (IHSN Toolkit)

The Economic Commission for Latin America and the Caribbean (ECLAC) Subregional Headquarters for the Caribbean, in collaboration with the World Bank, conducted a week-long Regional Workshop on Microdata Documentation and Dissemination. The workshop, which was funded by the Partnership in Statistics for Development in the Twenty-First Century (PARIS21) and the Organization for Economic Co-operation and Development (OECD), was held at the Hilton Hotel and Conference Centre in Port of Spain, Trinidad, from 26 to 30 April 2010. The main objective of the workshop was to provide training to member States on the Microdata Management Toolkit. This toolkit was developed by International Household Surveys Networks (IHSN) to assist in the documentation, dissemination and preservation of household survey, census and microdata in accordance with international standards and best practices. The training was organized in response to numerous requests by directors of statistics in the region for the development of capacity in that area. It was specifically timed to meet the training needs of those offices ahead of the 2010 round of Population and Housing Censuses.

Trade Facilitation and Paperless Trade Implementation Survey 2015

The Global Survey on Trade Facilitation and Paperless Trade Implementation 2014-2015 is a global effort led by the Economic and Social Commission for Asia and the Pacific (ESCAP) in collaboration with the other four United Nations Regional Commissions, namely, the Economic Commission for Latin America and the Caribbean (ECLAC), the Economic and Social Commission for Western Asia (ESCWA), the Economic Commission for Africa (ECA) and the Economic Commission for Europe (UNECE). The goal of the Global Survey is to gather information from the member states of the respective Regional Commissions on trade facilitation and paperless trade measures and strategies implemented at the national and regional levels. The results of the survey will enable countries and development partners to better understand and monitor progress on trade facilitation, support evidence-based public policies, share best practices and identify capacity building and technical assistance needs.
