International migration, remittances, and poverty in developing countries

Few studies have examined the impact of international migration and remittances on poverty in a broad cross-section of developing countries. The authors try to fill this gap by constructing a new data set on poverty, international migration, and remittances for 74 low- and middle-income developing countries. Four key findings emerge: 1) International migration-defined as the share of a country's population living abroad-has a strong, statistical impact in reducing poverty. On average, a 10 percent increase in the share of international migrants in a country's population will lead to a 1.9 percent decline in the share of people living in poverty ($1.00 a person a day). 2) Distance to a major labor-receiving region-like the United States or OECD (Europe)-has an important effect on international migration. Developing countries that are located closest to the United States or OECD (Europe) are also those countries withthe highest rates of migration. 3) An inverted U-shaped curve exists between the level of country per capita income and international migration. Developing countries with low or high per capita GDP produce smaller shares of international migrants than do middle-income developing countries. The authors find no evidence that developing countries with higher levels of poverty produce more migrants. Because of considerable travel costs associated with international migration, international migrants come from those income groups which are just above the poverty line in middle-income developing countries. 4) International remittances-defined as the share of remittances in country GDP-have a strong, statistical impact in reducing poverty. On average, a 10 percent increase in the share of international remittances in a country's GDP will lead to a 1.6 percent decline in the share of people living in poverty.Environmental Economics&Policies,Economic Conditions and Volatility,Health Economics&Finance,Public Health Promotion,Health Monitoring&Evaluation,Health Monitoring&Evaluation,Environmental Economics&Policies,Poverty Assessment,Economic Conditions and Volatility,Achieving Shared Growth

Remittances, consumption and investment in Ghana

This paper uses a new, nationally-representative household survey from Ghana to analyze within a rigorous econometric framework how the receipt of internal remittances (from within Ghana) and international remittances (from African or other countries) affects the marginal spending behavior of households on a broad range of consumption and investment goods, including food, education and housing. Contrary to other studies, which find that remittances are spent disproportionately on consumption (food and consumer goods/durables) or investment goods (education and housing), the findings show that households receiving remittances in Ghana do not spend more at the margin on food, education and housing than households with similar income levels and characteristics that do not receive remittances. When the analysis controls for endogeneity and selection bias, the findings show that any differences in the marginal spending behavior between remittance-receiving and non-receiving households are explained completely by the observed and unobserved characteristics of households. Households in Ghana treat remittances just like any other source of income, and there are no changes in marginal spending patterns for households with the receipt of remittance income.Population Policies,Access to Finance,Debt Markets,Remittances,

The impact of remittances on poverty and inequality in Ghana

This paper uses a new, 2005/06 nationally-representative household survey to analyze the impact of internal remittances (from Ghana) and international remittances (from African and other countries) on poverty and inequality in Ghana. To control for selection and endogeneity, it uses a two-stage multinomial logit model with instrumental variables focusing on variations in migration networks and remittances among various ethno-religious groups in Ghana. The paper finds that both internal and international remittances reduce the level, depth, and severity of poverty in Ghana. However, the size of the poverty reduction depends on the type of remittances received. In general, poverty in Ghana is reduced more by international than internal remittances. For households receiving international remittances, the level of poverty falls by 88.1 percent with the inclusion of remittances; for households receiving internal remittances, poverty falls by 69.4 percent with the inclusion of remittances. The paper also finds that both types of remittances increase income inequality in Ghana. For households with internal remittances, the inclusion of remittances causes the Gini coefficient to rise by 4 percent, and for households with international remittances, the inclusion of remittances causes the Gini to increase by 17.4 percent.Population Policies,Access to Finance,Remittances,Debt Markets,Rural Poverty Reduction

Mapping and monitoring changes in vegetation communities of Jasper Ridge, CA, using spectral fractions derived from AVIRIS images

An important application of remote sensing is to map and monitor changes over large areas of the land surface. This is particularly significant with the current interest in monitoring vegetation communities. Most of traditional methods for mapping different types of plant communities are based upon statistical classification techniques (i.e., parallel piped, nearest-neighbor, etc.) applied to uncalibrated multispectral data. Classes from these techniques are typically difficult to interpret (particularly to a field ecologist/botanist). Also, classes derived for one image can be very different from those derived from another image of the same area, making interpretation of observed temporal changes nearly impossible. More recently, neural networks have been applied to classification. Neural network classification, based upon spectral matching, is weak in dealing with spectral mixtures (a condition prevalent in images of natural surfaces). Another approach to mapping vegetation communities is based on spectral mixture analysis, which can provide a consistent framework for image interpretation. Roberts et al. (1990) mapped vegetation using the band residuals from a simple mixing model (the same spectral endmembers applied to all image pixels). Sabol et al. (1992b) and Roberts et al. (1992) used different methods to apply the most appropriate spectral endmembers to each image pixel, thereby allowing mapping of vegetation based upon the the different endmember spectra. In this paper, we describe a new approach to classification of vegetation communities based upon the spectra fractions derived from spectral mixture analysis. This approach was applied to three 1992 AVIRIS images of Jasper Ridge, California to observe seasonal changes in surface composition

Temporal variation in spectral detection thresholds of substrate and vegetation in AVIRIS images

The ability to map changes over large surface areas over time is one of the advantages in using remote sensing as a monitoring tool. Temporal changes in the surface may be gradual, making them difficult to detect in the short-term, and because they commonly occur at the subpixel scale, they may be difficult to detect in the long-term as well. Also, subtle changes may be real or merely an artifact of image noise. It is, therefore, necessary to understand the factors that limit the detection of surface materials in evaluating temporal data. The spectral detectability of vegetation and soil in the 1990 July and October Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data of Jasper Ridge, CA was evaluated and compared

Churchman\u27s Inquiring Systems: Kernel Theories for Knowledge Management

Churchman [1971] defines inquiry as an activity that produces knowledge. He examines the epistemologies of five schools of philosophy from the perspective of general systems theory, asking the question as to whether each is suitable as the basis for the design of computer-based inquiring systems. He considers systems design and design theory in some detail. We believe that Churchman\u27s inquiring systems can form the basis for the design of knowledge management systems and that the IS research community has hardly tapped the potential of inquiring systems in that regard. Mason and Mitroff [1973] brought inquiring systems into the IS literature early on, essentially making the work endogenous to the field. We argue that building on inquiring systems can contribute to developing IS as a discipline by maintaining continuity in research and developing a theory that IS can call its own. We believe that the lack of use of Churchman\u27s work may be due to its lack of visibility in recent years and attempt to remedy that by summarizing the basics of the inquirers in some detail, trying not to interpret, but to remain faithful to the original. The paper encourages readers to study the original and develop their own notion of how the inquirers might be used in knowledgemanagement work. There are probably as many different perspectives on how inquiring systems could support KMS as there are IS researchers willing to study them. We would like to encourage a proliferation of such perspectives

A Parent-Led Intervention to Promote Recovery Following Pediatric Injury: Study Protocol for a Randomized Controlled Trial

Background: Injury is one of the most prevalent potentially emotionally traumatic events that children experience and can lead to persistent impaired physical and emotional health. There is a need for interventions that promote full physical and emotional recovery and that can be easily accessed by all injured children. Based on research evidence regarding post-injury recovery, we created the Cellie Coping Kit for Children with Injury intervention to target key mechanisms of action and refined the intervention based on feedback from children, families, and experts in the field. The Cellie Coping Kit intervention is parent-guided and includes a toy (for engagement), coping cards for children, and a book for parents with evidence-based strategies to promote injury recovery. This pilot research trial aims to provide an initial evaluation of the impact of the Cellie Coping Kit for Children with Injury on proximal targets (coping, appraisals) and later child health outcomes (physical recovery, emotional health, health-related quality of life). Method / Design: Eighty children (aged 8–12 years) and their parents will complete a baseline assessment (T1) and then will be randomly assigned to an immediate intervention group or waitlist group. The Cellie Coping Kit for Injury Intervention will be introduced to the immediate intervention group after the T1 assessment and to the waitlist group following the T3 assessment. Follow-up assessments of physical and emotional health will be completed at 6 weeks (T2), 12 weeks (T3), and 18 weeks (T4). Discussion: This will be one of the first randomized controlled trials to examine an intervention tool intended to promote full recovery after pediatric injury and be primarily implemented by children and parents. Results will provide data on the feasibility of the implementation of the Cellie Coping Intervention for Injury as well as estimations of efficacy. Potential strengths and limitations of this design are discussed. Trial Registration: Clinicaltrials.gov, NCT03153696. Registered on 15 May 2017
