Domestic Violence and Labor Market Outcomes: Evidence from a Mixed-Race Developing Country

This study investigates the heterogeneous effects of domestic violence over labor markets in an ethnically fragmented country such as Bolivia. Among developing countries, Bolivia “excels” in having one of the highest levels of domestic violence in the region. Anecdotal evidence and empirical evidence suggest that response to domestic violence is not homogeneous across different ethnic groups. Using information from the Demographic and Health Survey (DHS) for Bolivia, we examine the heterogeneous impacts of domestic violence over one of the key labor market outcomes such as employment. We employ a probabilistic decision model and treatment regression techniques to examine this effect. We claim that the impact of domestic violence on labor markets is limited among indigenous people, given that violence is, to some extent, socially recognized and accepted. We find that for most of the cases, indigenous women are less responsive to domestic violence than non-indigenous ones, except for groups with a high income level. Our results are robust for alternative methodologies to address possible endogeneity problems.labor markets, domestic violence, Bolivia, indigenous

Los sindicatos y rendimiento económico en los países en desarrollo: Estudios de Casos de América Latina

This paper analyzes the economic impact of unions on productivity in the manufacturing sector across six Latin American countries: Argentina, Bolivia, Chile, Mexico, Uruguay, and Panama. Using an augmented Cobb-Douglas production function, the paper finds that unions have positive, but mostly small, effects on productivity, with the exception of Argentina, with a large negative effect, and Bolivia, with no effect. An analysis on profitability shows that, in most cases, the positive productivity effects barely offset higher union compensation, and that unions are negatively related to investment in capital and R & D. Different explanations for these effects are discussed.Este artículo analiza el impacto económico de los sindicatos sobre la productividad en el sector manufacturero en seis países de América Latina: Argentina, Bolivia, Chile, México, Uruguay y Panamá. Utilizando una función de producción aumentada de Cobb-Douglas, el documento encuentra que los sindicatos tienen efectos positivos, pero sobre todo pequeños, sobre la productividad, con la excepción de Argentina, con un gran efecto negativo, y Bolivia, sin efecto. Un análisis de la rentabilidad muestra que, en la mayoría de los casos, los efectos positivos de la productividad apenas compensan una indemnización sindical más alta, y que los sindicatos están relacionados negativamente con la inversión en capital y en I + D. En el artículo se discuten diferentes explicaciones de estos efectos

Where and How to Look for Help Matters: Analysis of Support Exchange in Online Health Communities for People Living with HIV

Research is scarce on how direct and indirect support seeking strategies affect support exchange in online health communities. Moreover, prior research has relied mostly on content analysis of forum posts at the post level. In order to generate a more fine-grained analysis of support exchange, we conducted content analysis at the utterance level, taking directness of support seeking, quality of provision, forum type, and seeker gender into account. Our analysis of four popular online support forums for people living with human immunodeficiency virus found that type of support sought and provided, support seeking strategy, and quality of emotional support provision differed in care provider/formal forums versus social/informal forums. Interestingly, indirect support seeking tended to elicit more supportive emotional responses than direct support seeking strategies in all forums; we account for this in terms of type of support sought. Practical implications for online support communities are discussed

Experimental evaluation of control fluid fallback during off-bottom well control in vertical and deviated wells

This study measured the liquid fallback during simulated blowout conditions. The purpose of the study was to establish a basis for developing a procedure for controlling blowouts that relies on the accumulation of liquid kill fluid injected while the well continues to flow. The results from experiments performed with air, water, 10.5 ppg and 12.0 ppg mud in an experimental 48 ft flow loop at 0°, 20°, 40°, 60° and 75° deviation angles from the vertical, as well as results from full-scale experiments performed with natural gas and water based drilling fluid in a vertical 2787-foot deep research well, are presented. The results show that the critical velocity that prevents control fluid accumulation can be predicted by Turner\u27s model of terminal velocity based on the liquid droplet theory by also considering the flow regime of the continuous phase when evaluating the drag coefficient, and the angle of deviation from the vertical. Similarly, the amount of liquid that flows countercurrent into and accumulates in the well can be predicted based on the concept of zero net liquid flow (ZNLF) holdup. Finally all these concepts are integrated in the dynamic kill procedure, which is based on system performance analysis to better predict the feasibility of an off-bottom dynamic kill

Unemployed, Now What? The Effect of Immigration on Unemployment Transitions of Native-born Workers in the United States

Although one would expect the unemployed to be the population most likely affected by immigration, most of the studies have concentrated on investigating the effects immigration has on the employed population. Little is known of the effects of immigration on labor market transitions out of unemployment. Using the basic monthly Current Population Survey from 2001 and 2013 we match data for individuals who were interviewed in two consecutive months and identify workers who transition out of unemployment. We employ a multinomial model to examine the effects of immigration on the transition out of unemployment, using state-level immigration statistics. The results suggest that immigration does not affect the probabilities of native-born workers finding a job. Instead, we find that immigration is associated with smaller probabilities of remaining unemployed, but it is also associated with higher probabilities of workers leaving the labor force. This effect impacts mostly young and less educated people

Standard Error Correction in Two-Stage Optimization Models: A Quasi-Maximum Likelihood Estimation Approach

Following Wooldridge (2014), we discuss and implement in Stata an efficient maximum likelihood approach to the estimation of corrected standard errors of two-stage optimization models. Specifically, we compare the robustness and efficiency of this estimate using different non-linear routines already implemented in Stata such as ivprobit, ivtobit, ivpoisson, heckman, and ivregress

Unions, Wage Gaps, and Wage Dispersion: New Evidence from the Americas

Using a common methodology, the effects of unions on wage levels and wage dispersion are estimated for two neighboring countries, Bolivia and Chile, and for the U.S. The analysis shows that unions have broadly similar effects on the wage distribution within these three economies. The findings suggest that the political economy of unions, coupled with market constraints on labor costs, produce commonality in union wage effects that transcend other economic and institutional differences

Finite mixture models for linked survey and administrative data: estimation and post-estimation

esearchers use finite mixture models (FMMs) to analyze linked survey and administrative data on labor earnings taking account of various types of measurement error in each data source. Different combinations of error-ridden and/or error-free observations characterize latent classes. Latent class probabilities depend on the probabilities of the different types of error. We introduce a suite of Stata commands to fit FMMs to linked survey-administrative data: there is a general model and seven simpler variants. We also provide post-estimation commands for assessment of reliability, marginal effects, data simulation, and prediction of hybrid variables that combine information from both data sources about the outcome of interest. Our software can also be used to study measurement errors in other variables besides labor earnings

Modelling errors in survey and administrative data on employment earnings: sensitivity to the fraction assumed to have error-free earnings

Kapteyn and Ypma (Journal of Labour Economics 2007) is an influential study of errors in survey and administrative data on employment earnings. To fit their mixture models, Kapteyn and Ypma assume a specific fraction of their sample have error-free earnings. Using a new UK dataset, we assess the sensitivity of model estimates and post-estimation statistics to variations in this fraction and find some lack of robustness
