    Keywords: Graue Literatur
    Abstract: Differences in management quality are an important contributor to productivity differences across countries. A key question is how to best improve poor management in developing countries. This paper tests two different approaches to improving management in Colombian auto parts firms. The first uses intensive and expensive one-on-one consulting, while the second draws on agricultural extension approaches to provide consulting to small groups of firms at approximately one-third of the cost of the individual approach. Both approaches lead to improvements in management practices of a similar magnitude (8-10 percentage points), so that the new group-based approach dominates on a cost-benefit basis. Moreover, the paper finds some evidence that the group-based intervention led to increases in firm size over the next three years, while the impacts on firm outcomes are smaller and statistically insignificant for the individual consulting. The results point to the potential of group-based approaches as a pathway to scaling up management improvements

    Abstract: "The degree of mobility in incomes is often seen as an important measure of the equality of opportunity in a society and of the flexibility and freedom of its labor market. But estimation of mobility using panel data is biased by the presence of measurement error and non-random attrition from the panel. This paper shows that dynamic pseudo-panel methods can be used to consistently estimate measures of absolute and conditional mobility in the presence of non-classical measurement errors. These methods are applied to data on earnings from a Mexican quarterly rotating panel. Absolute mobility in earnings is found to be very low in Mexico, suggesting that the high level of inequality found in the cross-section will persist over time. However, the paper finds conditional mobility to be high, so that households are able to recover quickly from earnings shocks. These findings suggest a role for policies which address underlying inequalities in earnings opportunities. "--World Bank web site

    Abstract: "The authors investigate the impact of international migration on child health outcomes in rural Mexico using a nationally representative demographic survey. They use historic migration networks as instruments for current household migration to the United States in order to correct for the possible endogeneity of migrant status. They find that children in migrant households have lower rates of infant mortality and higher birth-weights. The authors study the channels through which migration may affect health outcomes and find evidence that migration raises health knowledge in addition to the direct effect on wealth. However they also find that preventative health care, such as breastfeeding and vaccinations, is less likely for children in migrant households. These results provide a broader and more nuanced view of the health consequences of migration than is offered by the existing literature. "--World Bank web site

    Keywords: Households ; Income ; Poverty ; Households ; Income ; Poverty
    Abstract: "Theories of poverty traps stand in sharp contrast to the view that anybody can make it through hard work and thrift. However, empirical detection of poverty traps is complicated by the lack of long panels, measurement error, and attrition. This paper shows how dynamic pseudo-panel methods can overcome these difficulties, allowing estimation of non-linear income dynamics and testing for the presence of poverty traps. The paper explicitly allows for individual heterogeneity in income dynamics to account for the possibility that particular groups of individuals may face traps, even if the average individual does not. These methods are used to examine the evidence for a poverty trap in labor earnings, income, and expenditure in Mexico and are compared to panel data estimates from a short rotating panel. The results do find evidence of nonlinearities in household income dynamics and demonstrate large bias in the panel data estimates. Nevertheless, even after allowing for heterogeneity and accounting for measurement error, the paper finds no evidence of the existence of a poverty trap for any group in the sample.

    Keywords: Emigration and immigration ; Foreign workers ; Passports ; Emigration and immigration ; Foreign workers ; Passports
    Abstract: "Increased attention to the development potential of international migration has led to calls for greater global cooperation and for industrial countries to consider temporary worker programs and other options for increasing the number of immigrants admitted. But less attention has been devoted to policies that migrant-sending countries pursue that impact on the ability of people to emigrate under the existing system. This paper documents the existence and impact of two such policies: passport costs and legal restrictions on emigration. New data collected on passport costs in 127 countries reveals enormous variation in the cost of a passport from one country to the next. One in every 10 countries in the sample is found to have passport costs exceeding 10 percent of annual per capita income. High passport costs are found to be associated with poor governance, especially in terms of the quality of the bureaucracy, and with lower levels of migration. Countries that place legal restrictions on the rights of women to emigrate are also found to have lower migration rates than countries with similar income and population levels. These findings suggest there is scope for some developing countries to receive greater benefits from migration by tearing down the paper walls they place around their own citizens.

    Keywords: Educational attainment ; Educational attainment ; Mexico Emigration and immigration ; Mexico Rural conditions ; Mexico Emigration and immigration ; Mexico Rural conditions
    Abstract: "The authors examine the impact of migration on educational attainment in rural Mexico. Using historical migration rates by state to instrument for current migration, they find evidence of a significant negative effect of migration on schooling attendance and attainment of 12 to 18 year-old boys and 16 to 18 year-old girls. IV-Censored Ordered Probit results show that living in a migrant household lowers the chances of boys completing junior high school and of boys and girls completing high school. The negative effect of migration on schooling is somewhat mitigated for younger girls with low educated mothers, which is consistent with remittances relaxing credit constraints on education investment for the very poor. However, for the majority of rural Mexican children, family migration depresses educational attainment. Comparison of the marginal effects of migration on school attendance and on participation in other activities shows that the observed decrease in schooling of 16 to 18 year-olds is accounted for by the current migration of boys and increased housework for girls.

    How pro-poor is the selection of seasonal migrant workers from Tonga under New Zealand's recognized Seasonal Employer Program ? (2008)

    Keywords: Seasonal labor ; Seasonal labor ; Seasonal labor ; Seasonal labor
    Abstract: "Temporary migration programs for unskilled workers are increasingly being proposed as a way to both relieve labor shortages in developed countries and aid development in sending countries without entailing many of the costs associated with permanent migration. New Zealand's new Recognized Seasonal Employer program is designed to enable unskilled workers from the Pacific Islands to work in horticulture and viticulture in New Zealand for a period of up to seven months. However, the development impact on a sending country will depend not only on how many workers participate, but also on who participates. This paper uses new survey data from Tonga to examine the process of selecting workers for the Recognized Seasonal Employer program, and to analyze how pro-poor the recruitment process has been to date. The findings show that recruited workers come from largely agricultural backgrounds, and have lower average incomes and schooling levels than Tongans not participating in the program. Comparing the characteristics of program workers with those of Tongans applying to permanently migrate to New Zealand through the Pacific Access Category, the program workers are more rural and less educated. The program therefore seems to have succeeded in creating new opportunities for relatively poor and unskilled Tongans to work in New Zealand. "--World Bank web site

    Keywords: Seasonal labor ; Seasonal labor ; Seasonal labor ; Seasonal labor
    Abstract: "New Zealand's new Recognized Seasonal Employer program allows workers from the Pacific Islands to come to New Zealand for up to seven months to work in the horticulture and viticulture industries. One of the explicit objectives of the program is to encourage economic development in the Pacific. This paper reports the results of a baseline survey taken in Vanuatu, which the authors use to examine who wants to participate in the program, and who is selected among those interested. The findings show that the main participants are males in their late 20s to early 40s, and most are married and have children. Most workers are subsistence farmers in Vanuatu and have not completed more than 10 years of schooling. Such workers would be unlikely to be accepted under existing migration channels. Nevertheless, the program workers from Vanuatu tend to come from wealthier households, and have better English literacy and health than individuals not applying for the program. Lack of knowledge about the policy and the costs of applying appear to be the main barriers preventing poorer individuals applying. "--World Bank web site

    Parallel Title: Bruhn, Miriam In pursuit of balance
    Abstract: "Randomized experiments are increasingly used in development economics, with researchers now facing the question of not just whether to randomize, but how to do so. Pure random assignment guarantees that the treatment and control groups will have identical characteristics on average, but in any particular random allocation, the two groups will differ along some dimensions. Methods used to pursue greater balance include stratification, pair-wise matching, and re-randomization. This paper presents new evidence on the randomization methods used in existing randomized experiments, and carries out simulations in order to provide guidance for researchers. Three main results emerge. First, many researchers are not controlling for the method of randomization in their analysis. The authors show this leads to tests with incorrect size, and can result in lower power than if a pure random draw was used. Second, they find that in samples of 300 or more, the different randomization methods perform similarly in terms of achieving balance on many future outcomes of interest. However, for very persistent outcome variables and in smaller sample sizes, pair-wise matching and stratification perform best. Third, the analysis suggests that on balance the re-randomization methods common in practice are less desirable than other methods, such as matching. "--World Bank web site

    Keywords: Social surveys ; Social surveys
    Abstract: "The majority of economic decisions taken by individuals are forward looking and thus involve their expectations of future outcomes. Understanding the expectations that individuals have is thus of crucial importance to designing and evaluating policies in health, education, finance, migration, social protection, and many other areas. However, the majority of developing country surveys are static in nature and do not contain information on the subjective expectations of individuals. Possible reasons given for not collecting this information include fears that poor, illiterate individuals do not understand probability concepts, that it takes far too much time to ask such questions, or that the answers add little value. This paper provides a critical review and new analysis of subjective expectations data from developing countries and refutes each of these concerns. The authors find that people in developing countries can generally understand and answer probabilistic questions, such questions are not prohibitive in time to ask, and the expectations are useful predictors of future behavior and economic decisions. The paper discusses the different methods being tried for eliciting such information, the key methodological issues involved, and the open research questions. The available evidence suggests that collecting expectations data is both feasible and valuable, suggesting that it should be incorporated into more developing country surveys. "--World Bank web site
