Factors affecting cotton supply at the farm level in Metema District of Ethiopia

Current available records show that Ethiopia is receiving negligible benefits from its cotton and textile products export partly on account of low production at the farm level. Our objective was to study factors responsible for the low production. The factors affecting farm level marketable supply of cotton were analyzed using Robust OLS regression analysis. Results showed that size of land allocated for cotton, productivity per hectare and access to credit were significant factors affecting farm level marketable cotton supply. Based on the study, policy interventions required to increase the supply of cotton were suggeste

Structure-Conduct-Performance of Cotton Market: The Case of Metema District, Ethiopia

The efficiency of cotton market chain that can have great influence on farm level supply of marketable cotton was evaluated for Metema District of Ethiopia, using structure-conduct-performance approach. Market concentration ratio (CR4) at District level was 49.76 percent and there were observed barriers to entry into the cotton market. These structural characteristics indicate oligopolistic structure of cotton market at the District level. Cotton market at ginneries and textile factories were highly oligopolized by two ginneries and three textile factories. Buying, selling, and pricing strategies, which are indicators of market conduct showed deviation of cotton market from competitive market norms. The performance of cotton market chain analyzed using Marketing Margins supplemented with analysis of costs incurred and gross profits generated for different market chain actors, showed poor performance of the chain. In the chain farmers are the most disadvantaged chain actor

A SPATIAL MODEL OF REGIONAL VARIATIONS IN EMPLOYMENT GROWTH IN APPALACHIA

In this study, a spatial equilibrium model of employment growth is developed and empirically estimated by Generalized Spatial Two-Stage Least Squares (GS2SLS) estimator using cross-sectional data from Appalachian counties for 1990-2000. Besides the existence of spatial spillover effects, the results suggest that agglomerative effects that arise from the demand and the supply side contribute to employment growth in the study area during the study period. The policy implications of the findings are: (1) Regional cooperation of counties and communities is advisable and may in fact be necessary to design effective policies to encourage employment growth; and (2) Policy makers at the county level may need to design policies that can attract people with high endowments of human capital and higher income into their respective counties.APPALACHIA, EMPLOYMENT GROWTH, SPATIAL MODEL

A Spatial Panel Simultaneous-Equations Model of Business Growth, Migration Behavior, Local Public Services and Household Income in Appalachia

In this paper we develop a spatial panel simultaneous-equations model of business growth, migration behavior, local public services and median household income in a partial lag-adjustment growth-equilibrium framework and utilizing a one-way error component model for the disturbances. This model is an extension of the jobs follow people or people follow jobs literature and it improved previous models in the growth-equilibrium tradition by: (1) explicitly modeling local government and regional income in the growth process; (2) explicitly modeling gross in-migration and gross out-migration separately in order to spell out the differential effects, which used to be glossed over under net population change in previous studies; (3) explicitly incorporating both spatially lagged dependent variables and spatially lagged error terms to account for spatial spillover effects in the data set; and (4) extending and generalizing the modeling and estimation of simultaneous systems of spatially interrelated cross sectional equations into a panel data setting. To estimate the model, we develop a five-step new estimation strategy by generalizing the Generalized Spatial Three-Stage Least Squares (GS3SLS) approach outlined in Kelejian and Prucha (2004) into a panel data setting. The empirical implementation of the model uses county-level data from the 418 Appalachian counties for 1980-2000. Generally, the results from these model estimations are consistent with the theoretical expectations and empirical findings in the equilibrium growth literature and provide support to the basic hypotheses of this study. First, the estimates show the existence of feedback simultaneities among the endogenous variables of the model. Second, the results also show the existence of conditional convergence with respect to the respective endogenous variable of each equation of the model and the speed of adjustment parameters are generally comparable to those in literature. Third, the results from the parameter estimation of the model indicate the existence of spatial autoregressive lag effects and spatial cross-regressive lag effects with respect to the endogenous variables of the model. One of the key conclusions is that sector specific policies should be integrated and harmonized in order to give the desirable outcome. Besides, regionally focusing resources for development policy may yield greater returns than treating all locations the same.Community/Rural/Urban Development,

Sustainable land management through market oriented commodity development: Case studies from Ethiopia

Land degradation has been identified as severe environmental problem in Ethiopia, especially since the early 1970s. Because there is significant degradation on cultivated lands in Ethiopia, there is potentially high payoff to addressing degradation in the country. In this paper we focus mainly on the effect of short-term benefits to farmers and the explicit considerations of the linkages between natural resource management and market-oriented commodity development on the adoption and scaling out of sustainable land management practices. We hypothesize that linking natural resource management with market-oriented commodity development enhances sustainable land management by providing farmers with short-term benefits. We test this hypothesis with analysis of case studies of four districts in Ethiopia. Two of the case studies deal with the linkage between grazing land development and market-oriented livestock development, and the other two deal with the linkage between conservation agriculture and market-oriented crop production. Results indicate that, indeed, direct linkages of natural resource management with market-oriented commodity development that have profitable market opportunities can enhance sustainable land management. Results imply that participatory approaches to the appraisal of community resources, identification and prioritization of key constraints of commodity development, and implementation of interventions greatly facilitate adoption and scaling out of interventions

Significant association between perceived HIV related stigma and late presentation for HIV/AIDS care in low and middle-income countries: A systematic review and metaanalysis

Background Late presentation for human immunodeficiency virus (HIV) care is a major impediment for the success of antiretroviral therapy (ART) outcomes. The role that stigma plays as a potential barrier to timely diagnosis and treatment of HIV among people living with HIV/AIDS (acquired immunodeficiency syndrome) is ambivalent. This review aimed to assess the best available evidence regarding the association between perceived HIV related stigma and time to present for HIV/AIDS care. Methods Quantitative studies conducted in English language between 2002 and 2016 that evaluated the association between HIV related stigma and late presentation for HIV care were sought across four major databases. This review considered studies that included the following outcome:late HIV testing',late HIV diagnosis' andlate presentation for HIV care after testing'. Data were extracted using a standardized Joanna Briggs Institute (JBI) data extraction tool. Meta-Analysis was undertaken using Revman-5 software. I2 and chi-square test were used to assess heterogeneity. Summary statistics were expressed as pooled odds ratio with 95% confidence intervals and corresponding p-value. Results Ten studies from low-And middle- income countries met the search criteria, including six (6) and four (4) case control studies and cross-sectional studies respectively. The total sample size in the included studies was 3,788 participants. Half (5) of the studies reported a significant association between stigma and late presentation for HIV care. The meta-Analytical association showed that people who perceived high HIV related stigma had two times more probability of late presentation for HIV care than who perceived low stigma (pooled odds ratio = 2.4; 95%CI: 1.6±3.6, I2 = 79%). Conclusions High perceptions of HIV related stigma influenced timely presentation for HIV care. In order to avoid late HIV care presentation due the fear of stigma among patients, health professionals should play a key role in informing and counselling patients on the benefits of early HIV testing or early entry to HIV care. Additionally, linking the systems and positive case tracing after HIV testing should be strengthened

Associations between endometriosis and adverse pregnancy and perinatal outcomes: a population-based cohort study.

PURPOSE To examine the association between endometriosis and adverse pregnancy and perinatal outcomes (preeclampsia, placenta previa, and preterm birth). METHODS A population-based retrospective cohort study was conducted among 468,778 eligible women who contributed 912,747 singleton livebirths between 1980 and 2015 in Western Australia (WA). We used probabilistically linked perinatal and hospital separation data from the WA data linkage system's Midwives Notification System and Hospital Morbidity Data Collection databases. We used a doubly robust estimator by combining the inverse probability weighting with the outcome regression model to estimate adjusted risk ratios (RR) and 95% confidence intervals (CIs). RESULTS There were 19,476 singleton livebirths among 8874 women diagnosed with endometriosis. Using a doubly robust estimator, we found pregnancies in women with endometriosis to be associated with an increased risk of preeclampsia with RR of 1.18, 95% CI 1.11-1.26, placenta previa (RR 1.59, 95% CI 1.42-1.79) and preterm birth (RR 1.45, 95% CI 1.37-1.54). The observed association persisted after stratified by the use of Medically Assisted Reproduction, with a slightly elevated risk among pregnancies conceived spontaneously. CONCLUSIONS In this large population-based cohort, endometriosis is associated with an increased risk of preeclampsia, placenta previa, and preterm birth, independent of the use of Medically Assisted Reproduction. This may help to enhance future obstetric care among this population
