Malaria and National Income: Examining a Two Way Causal Relationship AgEcon
Datta, Saurabh; Reimer, Jeffrey J..
Simple plots of data show that malaria has a negative correlation with national income per capita, whether looking across countries at a point in time, or looking at a single country over time. Some countries have been able to move from an equilibrium characterized by low income and high malaria, to a new equilibrium with higher income and lower rates of malaria. This study develops and estimates a simultaneous equations model to explain these changes. We distinguish three potential causal chains: (a) the ability for decreases in malaria to increase income, (b) the ability for increases in income to reduce malaria (reverse causality), and (c) external factors that may lead to both higher income and lower malaria (incidental association). We find that...

Coping with Drought in Rice Farming in Asia: Insights from a Cross-Country Comparative Study AgEcon
Pandey, Sushil; Bhandari, Humnath; Ding, Shijun; Prapertchob, Preeda; Sharan, Ramesh; Naik, Dibakar; Taunk, Sudhir K.; Sastri, Asras.
Drought is a major constraint affecting rice production especially in rainfed areas of Asia. Despite its importance in rice growing areas, the magnitude of economic losses arising from drought, its impact on farm households and farmers' drought coping mechanisms are poorly understood. This paper provides insights into these aspects of drought based on a cross-country comparative analysis of rainfed rice growing areas in China, India and Thailand. The economic cost of drought is found to be substantially higher in eastern India than in the other two countries. Higher probability and greater spatial covariance of drought and less diversified farming systems with rice accounting for a large r share of household income are likely to be the main reasons for...

Measuring the impact of trade policy reform in Ireland: A disaggregated analysis of household impacts AgEcon
Miller, Ana Corina; Matthews, Alan; Boysen, Ole; Donnellan, Trevor; O'Donoghue, Cathal.
The purpose of this paper is to assess the impacts of further trade liberalisation on the agricultural sector in Ireland. In addition to evaluating the aggregate impacts on agricultural production as well as the spill-over effect of this on the non-agricultural sector and for overall Irish GDP, we evaluate the effects for different types of households. In order to capture economy-wide impacts of the policy reform, a CGE model was formulated and implemented using a social accounting matrix constructed for Ireland for the year 2005. Household effects are captured using representative households. The simulation results suggest a positive impact on the Irish economy as well as on the representative households. Many agricultural sectors contract in the process...

USING CLUSTER ANALYSIS IN MEASURING SOCIAL DOMAIN OF TERRITORIAL BRAND AgEcon
Baskakova, Irina; Stepanova, Zlata.
Territorial brand has a social dimension reflected in the social equilibrium and measurable with social effectiveness indicators. The paper offers social effectiveness analysis of territory using investigation object “territorial and social systems (TSS)” with their further classification according to social types based on cluster analysis. This method allows the authors to distinct four social types of TSS in Sverdlovsk region in accordance with such characteristics as financial activity, quality of life, social stability and ill-being levels. The results of investigation could be useful for brand policy of territorial authorities.

Potential Impacts of Golden Rice on Public Health in India AgEcon
Stein, Alexander J.; Sachdev, H.P.S.; Qaim, Matin.
Vitamin A deficiency (VAD) affects millions of people world-wide, causing serious health problems. Golden Rice (GR), which has been genetically engineered to produce beta-carotene, is being proposed as a remedy. While this new technology has aroused controversial debates, its nutritional impact and cost-effectiveness remain unclear. We determine the current burden of VAD in India from a public health perspective,and simulate the potential alleviating impact of GR using representative household food consumption data. Given broad public support, GR could more than halve the overall burden of VAD. Juxtaposing health benefits and overall costs suggests that GR is very costeffective.

Deregulation of the Maize Marketing System of Swaziland and Implications for Food Security AgEcon
Mashinini, Nkosazana N.; Obi, Ajuruchukwu; van Schalkwyk, Herman D..
Recent shortfalls in the supply of maize in the Kingdom of Swaziland have exacerbated the country's growing food insecurity and led to fresh calls for full deregulation of the maize marketing system. The proponents of deregulation believe that it eliminates inefficient production and service units by transferring resources to their best alternative uses. While the theoretical foundations for that position are not questionable, no studies have to date explicitly investigated the effects of the current arrangements and the potential effects of full deregulation. This paper reports on a study that examined the welfare effects of the regulation of the country's maize industry and considered the likely impacts of full deregulation of the industry. Using a...

Philippine Rice and Rural Poverty: An Impact Analysis of Market Reform Using CGE AgEcon
Cororaton, Caesar B..
This paper looks at how Philippine trade reform which consists of tariff reduction and elimination of quantitative restrictions (QR) on rice imports will affect poverty within two world trade scenarios: Doha and free world trade. The impact of Doha is very small and generates biased effects against agriculture. The impact of Philippine trade reform within the Doha agenda magnifies this biased effect, making rural households worse-off compared to urban households. However, eliminating rice QR generates a set of effects where consumer price reduction dominates nominal income decline. Thus, real income improves and poverty declines across household groups, but the net effects are lower in rural than in urban households. The impact of a free world trade...

Using Rural Household Income Survey Data to Inform Poverty Analysis: An Example from Mozambique AgEcon
Walker, Thomas S.; Boughton, Duncan; Tschirley, David L.; Pitoro, Raul; Tomo, Alda.
This paper demonstrates that income survey data can be very informative in explaining the variation across households in the incidence and severity of absolute poverty using a rural household income data set for Mozambique. Results from regression analysis of the sources of variation are used to simulate the impact of alternative agricultural interventions or strategies on rural poverty. Complementarities in the insights gained from consumption expenditure and income surveys may justify the collection and analysis of both types of information, especially in Sub-Saharan Africa, the one region of the world where the incidence of poverty is increasing.

The Effect of Household Wealth on Input Market Participation in Southern Africa AgEcon
Langyintuo, Augustine S.; Mungoma, Catherine.
Input technological change, fundamental to rural transformation, sometimes bypasses some rural populations because farmers are often reluctant to use new inputs due to production and price risks that could render their use unprofitable. The level of wealth of the household significantly relates to the household's ability to cope with such risks. Given the highly disproportionate distribution of wealth among rural households, this paper demonstrated that first stratifying households into meaningful wealth categories and estimating non-separable household improved variety adoption and seed demand models for each wealth category provides an opportunity to develop credible policy relevant recommendations on interventions that increase impact. This approach...

How Accurate is Participatory Wealth Ranking (PWR) in Targeting the Poor? A Case Study from Bangladesh AgEcon
Zeller, Manfred; Feulefack, Joseph; Neef, Andreas.
PWR is a participatory poverty assessment method that uses the ratings of local reference groups concerning the relative poverty status of households in their community. This paper assesses the accuracy of PWR in predicting absolute (income) poverty, and compares PWR with three other poverty assessment methods. Using a village census in 8 villages located in three of the six divisions of Bangladesh, 1660 households have been scored using the PWR method. A randomly selected subsample of 320 households was interviewed with a questionnaire employing the Living Standard Measurement Survey (LSMS) method. The data allow the identification of households that have per-capita expenditures below the international poverty line of 1 dollar a day. Our results show that...

The Impacts of Hurricane Mitch on Child Health: Evidence from Nicaragua AgEcon
Omitsu, Makiko; Yamano, Takashi.
By taking a rare opportunity to have both pre- and post-disaster survey data in Nicaragua in 1998 and 2001, we estimate the direct impacts of Hurricane Mitch on long-term child health status, measured in height-for-age z-scores, in the pooled cross section model. Especially, we focus on children who were younger than 2.5 years old at the time of Hurricane Mitch because the previous studies show that children under two to three years old are especially vulnerable to shocks. The results indicate that, in the 2001 survey, more than two years after experiencing Hurricane Mitch, children who were younger than 2.5 years old at the time of Hurricane Mitch have 0.35 points lower HAZ-scores and have 6.6 percent higher probability of stunting than expected. Although...

Operational Models for Improving the Targeting Efficiency of Agricultural and Development Policies: A systematic comparison of different estimation methods using out-of-sample tests AgEcon
Houssou, Nazaire; Zeller, Manfred.
Accurate targeting is key for the success of any development policy. While a number of factors might explain low targeting efficiency such as governance failure, political interference or lack of political will, this paper focuses on improving indicator-based models that identify poor households and smallholder farmers more accurately. Using stepwise regressions along with out-of-sample validation tests and receiver operating characteristic curves, this paper develops proxy means tests models for rural and urban Malawi. The models developed have proved their validity in an independent sample and therefore, can be used to target a wide range of development policies to the poor. This makes the models a potentially interesting policy tool for the country.

Poverty Mapping in Rural Syria for Enhanced Targeting AgEcon
Szonyi, Judit A.; de Pauw, Eddy; La Rovere, Roberto; Aw-Hassan, Aden.
Poverty maps allow assessing the well-being of rural population in a spatial context and identifying poverty hotspots. The maps can be used for regional policy analysis as they help in identifying areas where the rural poor live and where rural poverty is determined by the endowment and quality of natural resources and by population pressure. Natural resource endowment was assessed in the study by calculating an Agricultural Resource Index based on the availability of different major agricultural resources. Income per-capita was calculated by using census data, adjusted by the rural population density. The results show that the better income areas of Syria are located in the irrigated or higher-rainfall areas, but lower-income pockets exist due to the...

Social Capital and Farmer Welfare in Malaysia AgEcon
Yokoyama, Shigeki; Ali, Abu Kasim.
Effects of social capital (SC hereinafter) on household welfare (rice yield, income, health) were examined in rice granary area of south peninsula Malaysia. SC is categorized into eight types by its form (structural and cognitive) and function (birding, linking, and bracing). OLS is used for estimation on randomly selected 60 household data. As for self-rated health status, those attending more community activity (bonding structural SC) appear less healthy, seemingly that old farmers normally have more time to spend on community activities and they are more loyal to their organization. Those who highly evaluate bureaucratic organization (linking cognitive SC) are relatively healthier. Frequency of attending community activities (bonding structural SC) and...

Operational Poverty Targeting by Means of Proxy Indicators - The Example of Peru AgEcon
Johannsen, Julia; Zeller, Manfred.
The measurement of per capita daily expenditures which are compared with a monetary poverty line is the most widely used approach regarding poverty assessment. It is, however, based on the implementation of time and cost-intensive household surveys and, therefore, not an operational method for targeting poor households with development services. The paper shows how to identify an alternative poverty assessment tool for Peru. It consists of a maximum of 15 powerful predictors of per-capita household expenditures selected out of a wide range of indicators from different poverty dimensions such as education, assets and housing characteristics. By applying the maximizing-R-squared regression technique to identify the best 5 to 15 predictors, we avoid an...

Developing Poverty Assessment Tools Based on Principal Component Analysis: Results from Bangladesh, Kazakhstan, Uganda, and Peru AgEcon
Zeller, Manfred; Houssou, Nazaire; Alcaraz V., Gabriela; Schwarze, Stefan; Johannsen, Julia.
Developing accurate, yet operational poverty assessment tools to target the poorest households remains a challenge for applied policy research. This paper aims to develop poverty assessment tools for four countries: Bangladesh, Peru, Uganda, and Kazakhstan. The research applies the Principal Component Analysis (PCA) to seek the best set of variables that predict the household poverty status using easily measurable socio-economic indicators. Out of sample validations tests are performed to assess the prediction power of a tool. Finally, the PCA results are compared with those obtained from regressions models. In-sample estimation results suggest that the Quantile regression technique is the first best method in all four countries, except Kazakhstan. The PCA...

Disaster Risk, Social Vulnerability and Economic Development AgEcon
Ward, Patrick S.; Shively, Gerald E..
We examine the extent to which economic development reduces both a country's disaster risk and its social vulnerability to climate-related disasters. Global climate change is expected to increase the frequency and intensity of extreme weather events, such as droughts, floods, and various types of storms. Moreover, the effects of these extreme weather events are expected to be borne disproportionately in areas of the world already challenged by underdevelopment. We find that the ability of economic development to reduce disaster risk depends on a country's income level; additional income becomes less effective in reducing disaster risk as countries become wealthier. We find that, conditional on a disaster occurring, higher incomes generally reduce a...

Agricultural Productivity and Anticipated Climate Change in Sub-Saharan Africa: A Spatial Sample Selection Model AgEcon
Ward, Patrick S.; Florax, Raymond J.G.M.; Flores-Lagunes, Alfonso.
A cereal yield response function is estimated conditional upon environmental and topographical features to detect the effects of spatial heterogeneity and spatial dependence in explaining agricultural productivity across Sub-Saharan Africa. Controlling for direct and localized spillover effects, we then estimate the effect that projected changes in temperature and precipitation as a result of global climate change will have on agricultural production. We find that the estimated declines found in the climatological literature may overestimate actual declines, and factors such as spatial heterogeneity (i.e., country fixed effects) are profoundly more important to agricultural production.
