SAGA PUBLICATIONS Included here are Working Papers and Conference Papers. Publications on this page are organized by geographical focus: RETURN TO MAIN PUBLICATIONS BY GEOGRAPHY PAGE MADAGASCAR The Evolution of Groupwise Poverty in Madagascar, 1999-2005 August 2010 Stifel, David, Felix Forster, and Christopher B. Barrett This paper explores whether there exist differences in groupwise poverty in Madagascar; that is, whether there is a pattern over time of consistently poorer performance among subpopulations readily identifiable by one or more identity markers. Three key messages come out of this analysis. First, there exists a core type of household that remained persistently poor over the 1999-2005 period. These households were largely not members of the dominant ethnic group, land poor, lived in remote areas, and were headed by uneducated individuals, most commonly women. Second, in addition to establishing the existence of persistent differences in poverty across groups, relative differences in returns to education, land and remoteness underscore the existence of differences within groups, as one characteristic affects the returns to another. Third, persistent differences in groupwise poverty is associated with multiple different identities, some of which are offsetting and some of which are reinforcing. For example, women’s higher education tends to offset the disadvantages associated with being a head of household, while remoteness compounds the disadvantages associated with living in female-headed households. Paper presented at workshop hosted by the Centre for Research on Inequality, Human Security and Ethnicity (CRISE): The Persistence of Inequalities, Department of International Development, University of Oxford, April 4, 2008 In Journal of African Economies 19(4):559-604, August, 2010 Spatial Integration at Multiple Scales: Rice Markets in Madagascar May 2009 Moser, Christine, Christopher B. Barrett, and Bart Minten The dramatic increase in the price of rice and other commodities over the past year has generated new interest in how these markets work and how they can be improved. This article uses an exceptionally rich data set to test the extent to which markets in Madagascar are integrated across space at different scales of analysis and to explain some of the factors that limit spatial arbitrage and price equalization within a single country. We use rice price data across four quarters of 2000-2001 along with data on transportation costs and infrastructure availability for nearly 1,400 communes in Madagascar to examine the extent of market integration at three different spatial scales—subregional, regional, and national—and to determine whether non-integration is due to high transfer costs or lack of competition. The results indicate that markets are fairly well integrated at the subregional level and that factors such as high crime rates, remoteness, and lack of information are among the factors limiting competition. In Agricultural Economics 40(3): 281-294, May, 2009 Determinants of HIV Knowledge and Condom Use among Women in Madagascar: An Analysis Using Matched Household and Community Data April 2009 Glick, Peter, Josée Randriamamonjy, and David E. Sahn We estimate the determinants of HIV/AIDS knowledge and related behavior (use of condoms) among women in Madagascar, a country where prevalence remains low but conditions are ripe for a rapid increase in infections. In both rural and urban areas, more educated and wealthier women are more likely to know about means of preventing infection, less likely to have misconceptions about transmission, and more likely to use condoms. Community factors such as availability of health centers and access to roads also are associated with greater HIV knowledge. However, most of the large rural-urban difference in mean knowledge is due not to location per se but to differences in schooling and wealth; rather than simply being geographically targeted, AIDS education efforts must be designed to target and be understood by uneducated and poor subpopulations. In African Development Review 21(1): 147-179, April, 2009 The Demand for Hired Labor in Rural Madagascar January 2009 Randrianarisoa, Jean Claude, Christopher B. Barrett, and David C. Stifel CFNPP Working Paper, Cornell University, Ithaca, New York This paper estimates structural labor demand equations separately for farm and non-farm enterprises in rural Madagascar. We adapt recent labor supply estimation methods that address the general unobservability of both wage rates – due to widespread self-employment – and employers’ non-wage costs of hiring workers in order to fill a significant void in the existing literature. Labor demand in rural Madagascar appears strongly increasing in enterprise owners’ educational attainment, in enterprises’ capital stock, and in community-level public goods. Furthermore, labor demand appears wage inelastic, especially in the non-farm sector where government labor market policies, such as minimum wage laws, are more commonly enforced. Family Background, School Characteristics and Children’s Cognitive Achievement in Madagascar December 2008 Glick, Peter, Jean Claude Randrianarisoa, and David E. Sahn CFNPP Working Paper, Cornell University, Ithaca, New York This paper uses linked household, school, and test score data from Madagascar to investigate the relation of household characteristics and school factors to the cognitive skills of children ages 8 to 10 and 14 to 16. In contrast to most achievement test studies in developing countries, the study uses representative rather than school-based samples of children and combines detailed information on school and family background. Schooling of mothers matters far more for learning than schooling of fathers, perhaps reflecting differences in parental time spent with children on schoolwork. Even these effects, however, are significantly attenuated when controlling for choice of residence or school. Skills are also affected by aspects of primary schools, including teacher experience and infrastructure. Agricultural Technology, Productivity, and Poverty in Madagascar May 2008 Minten, Bart and Christopher B. Barrett This paper uses a unique, spatially-explicit dataset to study the link between agricultural performance and rural poverty in Madagascar. We show that, controlling for geographical and physical characteristics, communes that have higher rates of adoption of improved agricultural technologies and, consequently, higher crop yields enjoy lower food prices, higher real wages for unskilled workers, and better welfare indicators. The empirical evidence strongly favors support for improved agricultural production as an important part of any strategy to reduce the high poverty and food insecurity rates currently prevalent in rural Madagascar. In World Development 36(5): 797-822 Productivity in Malagasy Rice Systems: Wealth-differentiated Constraints and Priorities December 2007 Minten, Bart, Jean Claude Randrianarisoa and Christopher B. Barrett This study explores the constraints on agricultural productivity and priorities in boosting productivity in rice, the main staple in Madagascar, using a range of different data sets and analytical methods, integrating qualitative assessments by farmers and quantitative evidence from panel data production function analysis and willingness-to-pay estimates for chemical fertilizer. Nationwide, farmers seek primarily labor productivity enhancing interventions, e.g., improved access to agricultural equipment, cattle, and irrigation. Shock mitigation measures, land productivity increasing technologies, and improved land tenure are reported to be much less important. Research and interventions aimed at reducing costs and price volatility within the fertilizer supply chain might help at least the more accessible regions to more readily adopt chemical fertilizer Invited panel paper prepared for presentation at the International Association of Agricultural Economists Conference, Gold Coast, Australia, August 12-18, 2006 In Agricultural Economics 37(s1): 237-248, December, 2007 Are Client Satisfaction Surveys Useful? Evidence from Matched Facility and Household Data in Madagascar September 2007 Glick, Peter Client satisfaction surveys in developing countries are increasingly being promoted as a means of understanding health care quality and the demand for these services. However, concerns have been raised about the reliability of responses in such surveys: for example, ‘courtesy bias’ may lead clients, especially if interviewed upon exiting clinics, to provide misleadingly favorable responses. This study uses unique data from Madagascar to investigate these and other issues. Identical questions about satisfaction with local health care centers were asked in user exit surveys and in a population based household survey; the latter would be less contaminated by courtesy bias as well as changes in provider behavior in response to being observed. We find strong evidence that reported satisfaction is biased upward in exit surveys for subjective questions regarding (for example) treatment by staff and consultation quality, but is not biased for relatively objective questions about facility condition and supplies. The surveys do provide useful information on the determinants of consumer satisfaction with various dimensions of provider quality. Still, to obtain reliable estimates of consumer perceptions of health service quality, household based sampling appears to be far superior to the simpler exit survey method. Presented at the Regional Conference on “Education in West Africa: Constraints and Opportunities” in Dakar, Senegal, November 1-2, 2005 This is an expanded version of a paper published in Social Science and Medicine. Export Processing Zone Expansion in Madagascar: What are the Labor Market and Gender Impacts? December 2006 Glick, Peter and François Roubaud This paper analyzes part of the controversy over export processing zones—the labor market and gender impacts—using unique time-series labor force survey data from an African setting: urban Madagascar, in which the EPZ (or Zone Franche) grew very rapidly during the 1990s. Employment in the Zone Franche exhibits some basic patterns seen elsewhere in export processing industries of the developing world, such as the predominance of young, semi-skilled female workers. Taking advantage of microdata availability, we estimate earnings regressions to assess sector and gender wage premia. Zone Franche employment is found to represent a significant step up in pay for women who would otherwise be found in poorly remunerated informal sector work. Because it provides relatively high wage opportunities for those with relatively low levels of schooling, export processing development may also eventually have significant impacts on poverty. Further, by disproportionately drawing women from the low-wage sector informal sector (where the gender pay gap is very large) to the relatively well-paid export processing jobs (where pay is not only higher but also similar for men and women with similar qualifications), the EPZ has the potential to contribute to improved overall gender equity in earnings in the urban economy. Along many non-wage dimensions, jobs in the export processing zone are comparable to or even superior to other parts of the formal sector. However, the sector is also marked by very long working hours and high turnover, which may work to prevent it from being a source of long-term employment and economic advancement for women. Paper prepared for the conference “African Development and Poverty Reduction: The Macro-Micro Linkage” Cape Town, South Africa October 2004 In Journal of African Economies 15(4): 722-756, 2006 Agricultural Policy Impact Analysis: A Seasonal Multi-Market Model for Madagascar December 2006 Stifel, David C. and Jean-Claude Randrianarisoa We describe the main features and results of a multi-market model for Madagascar that focuses on income generating activities in an agricultural sector that is characterized by seasonal variability. We find evidence that investments in rural infrastructure and commercial food storage have both direct and indirect benefits on poor households. In Journal of Policy Modeling 28(9):1023-1027, 2006 The Complex Dynamics of Smallholder Technology Adoption: The Case of SRI in Madagascar November 2006 Moser, Christine M. and Christopher B. Barrett This paper explores the dynamics of smallholder technology adoption, with particular reference to a high-yielding, low-external input rice production method in Madagascar. We present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets. We then use a probit model and symmetrically censored least squares estimation of a dynamic Tobit model to analyze the decisions to adopt, expand and disadopt the method. We find that seasonal liquidity constraints discourage adoption by poorer farmers. Learning effects—both from extension agents and from other farmers—exert significant influence over adoption decisions. In Agricultural Economics 35(3):373-388, 2006. An Assessment of Changes in Infant and under-Five Mortality in Demographic and Health Survey Data for Madagascar September 2006 Glick, Peter, Stephen D. Younger, and David E. Sahn Repeated rounds of nationally representative surveys are an important source of information on changes in the welfare of the population. In particular, policymakers and donors in many developing countries rely heavily on the Demographic and Health Surveys (DHS) to provide information on levels and trends in indicators of the health status of the population, including child survival. The reliability of observed trends, however, depends strongly on the comparability across survey rounds of the sampling strategy and of the format of questions and how interviews ask them. In Madagascar, the most recent (2003/4) DHS indicated very sharp declines in rates of infant and under-five mortality compared with the previous survey from 1997. However, retrospective under-one and under-five mortality data in 1997 and 2003/4 for the same calendar years also show large differences, suggesting that this trend may be spurious. We employ a range of descriptive and multivariate approaches to investigate the issue. Despite evidence of significant interviewer recording errors (with respect to date of birth and age at death) in 2003/4, the most likely source of problems is that the two samples differ: comparisons of time-invariant characteristics of households and of women suggests that the later DHS sampled a somewhat wealthier (hence lower mortality) population. Corrections to the data using hazard survival model estimates are discussed. These suggest a much more modest reduction in infant and under-five mortality than indicated by the raw data for the two surveys. Robust Multidimensional Spatial Poverty Comparisons in Ghana, Madagascar, and Uganda April 2006 Duclos, Jean-Yves, David E. Sahn, and Stephen D. Younger We investigate spatial poverty comparisons in three African countries using multidimensional indicators of well-being. The work is analogous to the univariate stochastic dominance literature in that we seek poverty orderings that are robust to the choice of multidimensional poverty lines and indices. In addition, we wish to ensure that our comparisons are robust to aggregation procedures for multiple welfare variables. In contrast to earlier work, our methodology applies equally well to what can be defined as "union", "intersection," or "intermediate" approaches to dealing with multidimensional indicators of well-being. Further, unlike much of the stochastic dominance literature, we compute the sampling distributions of our poverty estimators in order to perform statistical tests of the difference in poverty measures. We apply our methods to two measures of well-being, the log of household expenditures per capita and children’s height-for-age z-scores, using data from the 1988 Ghana Living Standards Survey, the 1993 Enquête Permanente auprès des Ménages in Madagascar, and the 1999 National Household Survey in Uganda. Bivariate poverty comparisons are at odds with univariate comparisons in several interesting ways. Most importantly, we cannot always conclude that poverty is lower in urban areas from one region compared to rural areas in another, even though univariate comparisons based on household expenditures per capita almost always lead to that conclusion. In World Bank Economic Review 20(1):91-113 The Demand for Primary Schooling in Madagascar: Price, Quality, and the Choice Between Public and Private Providers February 2006 Glick, Peter, and David E. Sahn We estimate a discrete choice model of primary schooling and simulate policy alternatives for rural Madagascar. Poor households are substantially more price-responsive than wealthy ones, implying that fee increases for public schools will have negative effects on equity in education. Among quality factors, multigrade teaching (several classes being taught simultaneously by one teacher) has a strongly negative impact on public school enrollments. Simulations indicate that providing teachers to reduce by half the number of multigrade classes in public schools would lead to modest improvements in overall enrollments, would be feasible in terms of costs, and would disproportionately benefit poor children. In contrast, consolidation of primary schools combined with quality improvement would be ineffective because of the negative effect of distance to school. Other simulations point to limits to a strategy of public support for private school expansion as a means of significantly increasing enrollment rates or education quality; such an expansion may also reduce overall education equity.

Welfare Dynamics in Rural Kenya and Madagascar February 2006 Barrett, Christopher B., Paswel Phiri Marenya, John McPeak, Bart Minten, Festus Murithi, Willis Oluoch-Kosura, Frank Place, Jean Claude Randrianarisoa, Jhon Rasambainarivo and Justine Wangila This paper presents comparative qualitative and quantitative evidence from rural Kenya and Madagascar in an attempt to untangle the causality behind persistent poverty. We find striking differences in welfare dynamics depending on whether one uses total income, including stochastic terms and inevitable measurement error, or the predictable, structural component of income based on a household’s asset holdings. Our results suggest the existence of multiple dynamic asset and structural income equilibria, consistent with the poverty traps hypothesis. Furthermore, we find supporting evidence of locally increasing returns to assets and of risk management behaviour consistent with poor households' defence of a critical asset threshold through asset smoothing.

Rice Price Stabilization in Madagascar: Price and Welfare Implications of Variable Tariffs November 2005 Dorosh, Paul and Bart Minten Given the large share of major staples in the budgets of the poor, governments in many developing countries intervene in food markets to limit variation in the prices of staple foods. This paper examines the recent experience of Madagascar in stabilizing prices through international trade and the implications of adjustments in tariff rates. Using a partial equilibrium model, we quantify the overall costs and benefits of a change in import duties for various household groups, and compare this intervention to a policy of targeted food transfers or security stocks. Supermarkets, International Trade and Farmers in Developing Countries: Evidence from Madagascar September 2005 Minten, Bart, Lalaina Randrianarison, and Johan F. M. Swinnen Global retail companies (“supermarkets”) have an increasing influence on developing countries, through foreign investments and/or through the imposition of their private standards. The impact on developing countries and poverty is often assessed as negative. In this paper we show the opposite, based on an analysis of primary data collected to measure the impact of supermarkets on small contract farmers in Madagascar, one of the poorest countries in the world. Almost 10,000 farmers in the Highlands of Madagascar produce vegetables for supermarkets in Europe. In this global supply chain, small farmers’ micro-contracts are combined with extensive farm assistance and supervision programs to fulfill complex quality requirements and phyto-sanitary standards of supermarkets. Small farmers that participate in these contracts have higher welfare, more income stability and shorter lean periods. We also find significant effects on improved technology adoption, better resource management and spillovers on the productivity of the staple crop rice. The small but emerging modern retail sector in Madagascar does not (yet) deliver these benefits as they do not (yet) request the same high standards for their supplies. Getting the Inputs Right for Improved Agricultural Productivity in Madagascar, Which Inputs Matter and Are the Poor Different? June 2005 Randrianarisoa, Claude and Bart Minten We found that while farmers are willing to pay for improved irrigation infrastructure through water use associations, the amounts they are willing to contribute are significantly below the costs – and significantly below international standards – and this especially so for the poorest farmers. For chemical fertilizer, a more rational structuring of the fertilizer supply chain, with clear and consistent market signals, might help at least the more accessible regions to more readily adopt this input.

The Progression through School and Academic Performance in Madagascar Study: Preliminary Descriptive Results March 2005 Glick, Peter, Harivelo Rajemison, Arsène Ravelo, Yolande Raveloarison, Mamisoa Razakamanantsoa, and David E. Sahn This paper is a preliminary analysis of the Etude sur la Progression Scolaire et la Performance Academique en Madagascar (EPSPAM). The study is based on a nation-wide household survey with a special focus on schooling, complimented by academic and life skills tests and additional surveys of local schools and communities. The survey was designed to investigate the household, community, and school-level determinants of a range of education outcomes in Madagascar: primary and secondary enrollment, grade repetition and dropout during primary and lower secondary school cycles, transitions from primary to secondary school, and learning — both academic (math and French test scores) and non-academic ('life-skills'). It also seeks to understand the association of early academic performance, on the one hand, and subsequent school progression and scholastic attainment, on the other. The study also investigates the knowledge and perceptions of parents about the schools in their communities. In addition, the policy environment in education in Madagascar has been very dynamic in the last several years. Therefore the study also evaluates the implementation and impacts of several important recent policies in education, including the elimination of public primary school fees and the provision of books and supplies, as well as a series of administrative reforms such as the professionalization of the chefs CISCO and efforts to make school finances more transparent. Better Technology, Better Plots or Better Farmers? Identifying Changes In Productivity And Risk Among Malagasy Rice Farmers November 2004 Barrett, Christopher B., Christine M. Moser, Oloro V. McHugh, and Joeli Barison We introduce a method for properly attributing observed productivity and risk changes among new production methods, farmers, and plots by controlling for farmer and plot heterogeneity. Results from Madagascar show that the new system of rice intensification (SRI) is indeed a superior technology. Although about half of the observed productivity gains appear due to farmer characteristics rather than SRI itself, the technology generates the estimated average output gains of more than 84%. The increased estimated yield risk associated with SRI would nonetheless make it unattractive to many farmers within the standard range of relative risk aversion. In American Journal of Agricultural Economics 86(4):869-888 (November). Smallholder Identities and Social Networks: The Challenge of Improving Productivity and Welfare April 2004 Barrett, Christopher B. This paper proposes a general framework for resolving the puzzle of how to reconcile the mass of recent evidence on the salutary effects of social capital at the individual level with the casual, larger-scale observation that social embeddedness appears negatively correlated with productivity and material measures of welfare. It advances an analytical framework that not only explains individual productivity or technology adoption behavior as a function of the characteristics or behaviors of others, but that also explains the aggregate properties of social systems characterized by persistently low productivity. Examples from Kenya and Madagascar are used to illustrate the phenomena discussed. In The Social Economics of Poverty: Identities, Groups, Communities and Networks, Christopher B. Barrett, editor, London: Routledge, 2005. Public Service Provision, User Fees, and Political Turmoil January 2004 Fafchamps, Marcel and Bart Minten Following an electoral dispute, the central highlands of the island of Madagascar were subjected to an economic blockade during the first half of 2002. After the blockade ended in June 2002, user fees for health services and school fees were progressively eliminated. This paper examines the provision of schooling and health services to rural areas of Madagascar before, during, and after the blockade. We find that public services were more resilient to the blockade than initially anticipated, but that health services were more affected than schools. The removal of user fees had a large significant effect on public services that is distinct from the end of the blockade and the increase in school book provision. The Distribution of Social Services in Madagascar, 1993-99 December 2002 Glick, Peter and Mamisoa Razakamanantsoa While a number of benefit incidence studies of public expenditures have been carried out for African countries, there are very few studies that look at how the incidence of such expenditures has been changing over time. We use three rounds of nation-wide household surveys to analyze the distribution of public expenditures on education and health services in Madagascar over the decade of the 90s, a period of little economic growth but significant changes in social sector organization and budgets. Education and health services for the most part are found to be distributed more equally than household expenditures: therefore they serve to redistribute welfare from the rich to the poor. By stricter standards of progressivity, however, public services do poorly. Few services other than primary schooling accrue disproportionately to the poor in absolute terms. When we further adjust for differences in the numbers of potential beneficiaries in different expenditure quintiles (e.g., school-age children in the case of education), none of the education or health benefits considered appear to target the poor while several target the non-poor. We also find significant disparities in the use of services between rural and urban areas, and by province. On the other hand, for both education and health services, no notable gender differences exist in coverage. With regard to changes over the decade, primary enrollments rose sharply and also become significantly more progressive; since the country experienced little or no growth in household incomes during the period, this apparently reflects supply rather than demand side factors. The improvement in equity in public schooling occurred in part because the enrollment growth was in effect regionally targeted: it occurred only in rural areas, which are poorer. Also see, "The Distribution of Education and Health Services in Madagascar over the 1990s: Increasing Progressivity in an Era of Low Growth," in Journal of African Economies (October, 2005). Water Pricing, the New Water Law, and the Poor: An Estimation of Demand for Improved Water Services in Madagascar December 2002 Minten, Bart, Rami Razafindralambo, Zaza Randriamiarana, and Bruce Larson Generalized cost recovery is one of the basic principles of the new Water Law that has recently been adopted by the Malagasy government. However, the effect of this change in policy is still poorly understood. Based on contingent valuation surveys in an urban and a rural area in southern Madagascar, this study analyzes the effect of changes in prices for water services. The results suggest that a minimum size of 90 households in a village is necessary to reach full cost recovery for well construction. Given that this is significantly above the current size of villages in the survey area, full cost recovery seems therefore impossible and subsidies are necessary to increase access to improved water services. Cost recovery for maintenance is relatively easier to achieve. In urban areas, water use practices and willingness to pay for water services depend highly on household income. To better serve the poor, it is therefore suggested that rich households, who rely on private taps, cross-subsidize poor households as a significant number of households is unwilling or unable to pay for water from a public tap. Given that public taps make up a small part of the total consumption of the national water company JIRAMA, lower income from public taps are shown to have only a marginal effect on its total income. However, as experiences in other countries as well as in Madagascar have shown, a fee on public taps is necessary as water for free leads to spoilage, does not give any incentive for the distributor to expand networks, and might therefore be a bad policy for the poor overall.
