Does “buyer beware” work in migration? Contracting between brokers and migrants in Vietnam

This article is an attempt to open the lid a little of the “black box of migration” i.e. brokers. Analysing contracts between brokers and labour migrants, we identify four different forms of exploitation of migrants by brokers: expropriation of skill premium, risk shifting, over‐charging, and non‐refund of deposits. Opportunistic behaviour by brokers, as evidenced by such exploitation, is seen as a market failure that is explained by human attributes and transactional characteristics. Given the rigidities in the human attributes of the contracting parties and the nature of migration as a risky multi‐period transaction, proposals are made for non‐market interventions, which can lead to more equitable contracting.     

Life domain statisfactions and personal social integration

Data from a sample of northwestern Wisconsin residents were analyzed to identify the contribution of specific life domain satisfactions to the prediction of satisfaction with social integration. The results show the dominant impact of family satisfaction across the sample and its sub-populations of age, sex and income. The contribution of satisfactions with spare time activities and organizational involvement is also fairly uniform over the various groups. The impact of satisfactions with work, spiritual life and the remaining domains, on the other hand, is highly selective for different subpopulations. The results support the hypothesis of greater family and community centeredness among the lower income individuals and the elderly, and of the greater impact of organizational involvement, spare time activities and national affairs on the high income individuals. The differential impact of some of the resource and consumption domains across the subpopulations underlines the prominence of alternate consumption orientations and different resource instrumentalities for attaining the feelings of social integration.     

Variance estimation in complex survey sampling for generalized linear models

Summary.  Complex survey sampling is often used to sample a fraction of a large finite population. In general, the survey is conducted so that each unit (e.g. subject) in the sample has a different probability of being selected into the sample. For generalizability of the sample to the population, both the design and the probability of being selected into the sample must be incorporated in the analysis. In this paper we focus on non-standard regression models for complex survey data. In our motivating example, which is based on data from the Medical Expenditure Panel Survey, the outcome variable is the subject's 'total health care expenditures in the year 2002'. Previous analyses of medical cost data suggest that the variance is approximately equal to the mean raised to the power of 1.5, which is a non-standard variance function. Currently, the regression parameters for this model cannot be easily estimated in standard statistical software packages. We propose a simple two-step method to obtain consistent regression parameter and variance estimates; the method proposed can be implemented within any standard sample survey package. The approach is applicable to complex sample surveys with any number of stages.     

Complementary Drivers of New Product Development Performance: Cross‐Functional Coordination,Information System Capability,and Intelligence Quality

Coordination efforts that access and align relevant cross‐functional expertise are regarded as an essential element of innovation success. In recent years, these efforts have been further augmented through complementary investments in information systems, which provide the technological platforms for information sharing and coordination across functional and organizational boundaries. Somewhat overlooked has been the critical mediating role of the intelligence gained through these efforts and capabilities. This study draws on the theory of complementarity to elaborate on the nature of this mediating concept. Theoretical predictions of the model are tested using instrument variable regression analysis of data collected from a sample of publicly traded US manufacturing firms. The findings suggest that the effects of both internal and external coordination on market intelligence and supply‐chain intelligence are moderated by the firm's information system capability. The effect of both types of intelligence quality on new product development performance was contingent with the effects being enhanced (attenuated) when the market conditions were dynamic (stable). The results are robust to common‐method bias, endogeneity concerns, and alternative estimation methods.     

Transitions in Caregiving: Evaluating a Person-Centered Approach to Supporting Family Caregivers in the Community

Caregivers of older adults provide a wide range of informal supports and services that enable older adults to continue living in the community. This study describes the use of a multicomponent intervention combined with a person-centered approach to assist caregivers of older adults in the community. Four hundred and eighteen caregiver and care recipient dyads participated in this study and their outcomes related to burden, depression, well-being, and care recipient functional status were evaluated. The findings suggest that adult child and spousal caregivers experience burden differently. Programs designed to support caregivers must tailor services to the unique needs of adult child and spousal caregivers.     

Risk Perception and Human Health Risk in Rural Communities Consuming Unregulated Well Water in Saskatchewan,Canada

Rural communities dependent on unregulated drinking water are potentially at increased health risk from exposure to contaminants. Perception of drinking water safety influences water consumption, exposure, and health risk. A community‐based participatory approach and probabilistic Bayesian methods were applied to integrate risk perception in a holistic human health risk assessment. Tap water arsenic concentrations and risk perception data were collected from two Saskatchewan communities. Drinking water health standards were exceeded in 67% (51/76) of households in Rural Municipality #184 (RM184) and 56% (25/45) in Beardy's and Okemasis First Nation (BOFN). There was no association between the presence of a health exceedance and risk perception. Households in RM184 or with an annual income >$50,000 were most likely to have in‐house water treatment. The probability of consuming tap water perceived as safe (92%) or not safe (0%) suggested that households in RM184 were unlikely to drink water perceived as not safe. The probability of drinking tap water perceived as safe (77%) or as not safe (11%) suggested households in BOFN contradicted their perception and consumed water perceived as unsafe. Integration of risk perception lowered the adult incremental lifetime cancer risk by 3% to 1.3 × 10^?5 (95% CI 8.4 × 10^?8 to 9.0 × 10^?5) for RM184 and by 8.9 × 10^?6 (95% CI 2.2 × 10^?7 to 5.9 × 10^?5) for BOFN. Probability of exposure to arsenic concentrations >1:100,000, negligible cancer risk, was 23% for RM184 and 22% for BOFN.     

Environmental security and labor migration in Nepal

Do changes in environmental security that result from declining access to forest resources shape labor migration in a context where household production and consumption are intimately dependent on natural resources? Using 1996 household data from the Chitwan Valley of Nepal, we examined if a decrease in access to firewood increased the likelihood of migration of individuals for work. The results of multinomial logistic regression showed that, environmental insecurity was a significant predictor for migration regardless of destination, domestic or international. Labor requirements for household maintenance also played an important role in the decision to migrate. Management of forest resources and poverty alleviation by providing firewood substitutes and economic opportunities at the local level is likely to change the labor migration flow, which could be an important issue for future research.     

Explaining Self‐Employment Success and Failure: Wal‐Mart Versus Starbucks,or Schumpeter Versus Putnam*

Objectives. Two powerful socioeconomic innovations are sweeping the nation, led by Wal‐Mart Stores, Inc. and Starbucks Corp. These innovations both affect and are driven by profound labor market changes, but exactly how they affect self‐employment or entrepreneurship has not been investigated. We examine the independent effects of these phenomena on the returns to self‐employment, which is itself an underresearched topic in labor economics. Methods. We apply spatial econometric analysis to data from more than 3,000 U.S. counties to analyze how big‐boxes and drinking places that facilitate social networking affect self‐employment earnings. Findings. The presence of Wal‐Mart stores is associated with higher returns to self‐employment, whereas the results for coffee shops and drinking places are mixed. A negative interaction effect on earnings emerges when Wal‐Mart stores and drinking places exist in the same county. Conclusions. We confirm both Schumpeter's and Putnam's assertions about the importance of creative destruction and social networking in raising the productivity of entrepreneurs, although the latter effect is not as clear‐cut as the former.     

Population Exchange and its Impact on Literacy,Occupation and Gender – Evidence from the Partition of India

How do large scale, involuntary migrations and population exchanges affect sending and receiving communities? We examine the case of the partition of India in which approximately 17 million people moved within four years, resulting in one of the largest and most rapid population exchanges in human history. We find large effects due to the migration on a district's educational, occupational, and gender composition. Due to higher education levels amongst migrants, districts with 10 per cent greater inflows saw their literacy rates increase by 3 percentage points, while a 10 per cent increase in outflows reduced literacy by 1.2 percentage points. Due to disparities in the amount of land vacated by migrants, Indian districts with 10 per cent greater inflows saw a decline of 11 per centin agricultural occupations. Districts that experienced high inflows and outflows also experienced changes in gender composition. While the partition, driven along religious lines, increased religious homogenization within communities, our results suggest that this was accompanied by increased educational and occupational differences within religious groups. We conclude that these compositional effects, in addition to an aggregate population impact, are probably features of involuntary migrations and population exchanges and, as in the case of India, Pakistan, and Bangladesh, can have important long‐term consequences.
