EXOGENOUS PRODUCTION SHOCKS AND TECHNICAL EFFICIENCY AMONG TRADITIONAL IVORIEN RICE FARMERS AgEcon
Sherlund, Shane M.; Barrett, Christopher B..
This paper uses a unique panel data set and data envelopment analysis (DEA) to obtain estimates of technical efficiency for 492 traditional rice plots in Côte d'Ivoire. The objective of this paper is to explore the importance of explicitly controlling for exogenous shocks to production in technical efficiency estimation. We show how omission of such variables in highly stochastic production environments can lead to serious inferential errors, with potentially significant policy implications. Conventional DEA estimation of a production frontier, followed by second-stage Tobit estimation of the correlates of plot- level technical efficiency, suggest widespread and substantial inefficiency related to crop fragmentation and seed varieties. However, when...

Globalization and Poverty in Senegal: A Worst Case Scenario? AgEcon
Maertens, Miet; Colen, Liesbeth; Swinnen, Johan F.M..
There is no consensus about how globalization –trade and foreign investments – affects poverty reduction. Using household survey data, this study contributes to the empirical literature on globalization and poverty by analyzing the household-level implications of increased foreign investments and trade in the horticulture sector in Senegal. In many aspects this represents what many would consider a “worst-case scenario”. Stringent rich country standards are imposed on exports and the supply chain is controlled by a single multinational company with extreme levels of supply base consolidation, full vertical integration and complete exclusion of smallholder suppliers. We analyze and quantify income and poverty effects under these “worst-case conditions” and...

Receiving incorrect information is costly: Diffusion and accuracy of market information among farmers in northern Ghana AgEcon
Zanello, Giacomo; Shankar, Bhavani; Srinivasan, Chittur S..
The recent adoption of Information Communication Technologies (ICTs, namely mobile phones and radios) in rural areas of Sub- Saharan Africa has brought new evidence that an updated and reliable flow of information can have direct benefits for farmers' welfare. However, if correct market information can benefit the users, incorrect information can be costly. In this study we explore the diffusion (quantity) and the accuracy (quality) of price information among farmers in northern Ghana, with a focus on the role of ICTs.

Monitoring Poverty without Consumption Data: an Application Using the Albania Panel Survey AgEcon
Azzarri, Carlo; Carletto, Calogero; Davis, Benjamin; Zezza, Alberto.
In developing countries poverty is generally measured with expenditure data. Such data are difficult and costly to obtain and it is generally recommended to collect them every 3-5 years. In between surveys, however, there is a clear need to provide policymakers with information for the monitoring of poverty trends. The paper reviews several such methods and compares the poverty estimates and trends resulting from their application to a panel dataset for Albania. The results are broadly consistent across methods and point to an overall improvement in welfare conditions over time, although the magnitude of the changes differs by locale, with urban areas showing a larger improvement than their rural counterparts. However, given the sensitivity of the...

Political Selection and the Quality of Government: Evidence from South India AgEcon
Besley, Timothy; Pande, Rohini; Rao, Vijayendra.
This paper uses household data from India to examine the economic and social status of village politicians, and how individual and village characteristics affect politician behavior while in office. Education increases the chances of selection to public office and reduces the odds that a politician uses political power opportunistically. In contrast, land ownership and political connections enable selection but do not affect politician opportunism. At the village level, changes in the identity of the politically dominant group alters the group allocation of resources but not politician opportunism. Improved information flows in the village, however, reduce opportunism and improve resource allocation.

Poverty, Livestock and Household Typologies in Nepal AgEcon
Maltsoglou, Irini; Taniguchi, Kiyoshi.
Agriculture and livestock are key components of the livelihoods of the poor. Livestock make a substantial contribution to household livelihood's’ and currently sustain the livelihoods of an estimated 700 million rural poor in developing countries. In Nepal, poverty levels are extremely high and more than 80% of the population relies on the agriculture sector for employment and income generation. In this context, it is important to be able to understand the link between poverty and livestock and the possible impact of livestock policies on the poor. The aim of the analysis presented in this paper is twofold: firstly, to gain an in-depth understanding of the features that characterize the poor in Nepal so as to determine the role livestock plays in and for...

Revisiting the “Cotton Problem”: A comparative analysis of cotton reforms in Sub-Saharan Africa AgEcon
Delpeuch, Claire; Vandeplas, Anneleen; Swinnen, Johan F.M..
The cotton sector has been amongst the most regulated in Africa, and still is to a large extent in West and Central Africa (WCA), despite repeated reform recommendations by international donors. On the other hand, orthodox reforms in East and Southern Africa (ESA) have not always yielded the expected results. This paper uses a stylized contracting model to investigate the link between market structure and equity and efficiency in sub-Saharan cotton sectors and analyze the potential consequences of orthodox reforms in WCA. We argue that the level of the world price and of government intervention, the degree of post-reform competition, as well as the degree of parastatal inefficiency, all contribute to making reforms less attractive (but not less pressing)...

Asymmetric Response of Nutrient Intakes to Cereal Price Changes among the Poor in China: Implications for the Effect of Cereal Price Subsidies on the Poor’s Nutrient Intakes AgEcon
Shimokawa, Satoru.
Previous studies commonly assume that the effects of introducing and ending cereal price subsidies on the poor’s nutrient intakes are symmetric. We question the assumption of symmetry and show that the poor’s nutrient intakes respond asymmetrically to declines and increases in the price of cereal in China. Our results imply that introducing cereal price subsidies can increase the poor’s total energy intake by increasing their calorie intakes from fat and protein, and that ending such subsidies would insignificantly affect the poor’s total energy intake; however, it may further increase their calorie intakes from fat and protein.

The paradox of household resource endowment and land productivity in Uganda AgEcon
Ainembabazi, John Herbert; Angelsen, Arild.
The paper investigates the conflicting findings in empirical studies linking land productivity to plot size, livestock ownership, investment in farm assets, and land improvement practices. The conflicting impacts found are partly as a result of different model specifications, the type of data used – panel or cross sectional data – and possibly due to imperfections in rural markets. We control for these problems using household and plot level panel data from rural farmers in Uganda. We find that ownership of cattle has a negative and significant impact on land productivity. Investment in farm related assets, land improvements and other small livestock, however, significantly increases productivity. The conflicting impacts are a result of measurement error....

Intrahousehold Resource Allocation in Cote D'Ivoire: Social Norms, Separate Accounts and Consumption Choices AgEcon
Duflo, Esther; Udry, Christopher R..
In Cote d'Ivoire, as in much of Africa, husbands and wives farm different crops on separate plots. These different crops are differentially sensitive to particular kinds of rainfall shocks. We find that conditional on overall household expenditure, the composition of expenditure is sensitive to the gender of the recipient of a rainfall shock. For example, rainfall shocks associated with high women's income shift expenditure towards food. Social norms constrain the use of profits from yam cultivation, which is carried out by men. Correspondingly, we find that rainfall-induced fluctuations in income from yams are transmitted to expenditures on education and food, not to expenditures on private goods. We reject the hypothesis of complete insurance within...

The Efficacy of Parochial Politics: Caste, Commitment, and Competence in Indian Local Governments AgEcon
Munshi, Kaivan; Rosenzweig, Mark R..
Parochial politics is typically associated with poor leadership and low levels of public good provision. This paper explores the possibility that community involvement in politics need not necessarily worsen governance and, indeed, can be efficiency enhancing when the context is appropriate. Complementing the new literature on the role of community networks in solving market problems, we test the hypothesis that strong traditional social institutions can discipline the leaders they put forward, successfully substituting for secular political institutions when they are ineffective. Using new data on Indian local governments at the ward level over multiple terms, and exploiting the randomized election reservation system, we find that the presence of a...

The Impact of Rising Food Prices on the Poor AgEcon
Zezza, Alberto; Davis, Benjamin; Azzarri, Carlo; Covarrubias, Katia; Tasciotti, Luca; Anriquez, Gustavo.
This paper analyzes the household level impact of an increase in price of major tradable staple foods in a cross section of developing countries, using nationally representative household surveys. We find that, in the short term, poorer households and households with limited asset endowments and access to agricultural inputs will be hit the hardest by the price shock. Given the ample degree of heterogeneity among households and among the poor, the analysis emphasizes the importance of meaningful policy research to go beyond average impacts to look at how access to assets and inputs, livelihood strategies and other key household characteristics drive the magnitude and distribution of the effects of the price increases.

Working-Age Adult Mortality and Primary School Attendance in Rural Kenya AgEcon
Yamano, Takashi; Jayne, Thomas S..
The rapid increase in adult mortality due to the AIDS epidemic in sub-Saharan Africa raises great concern about potential intergenerational effects on children. This article estimates the impact of AIDS-related adult mortality on primary school attendance in rural Kenya using a panel of 1,266 households surveyed in 1997, 2000, and 2002. The paper distinguishes between effects on boys’ and girls’ education to understand potential gender differences resulting from adult mortality. We also estimate how adult mortality affects child schooling before as well as after the death occurs. The paper also estimates the importance of households’ initial asset levels in influencing the relationship between adult mortality and child school attendance. We find that all...

Finding Missing Markets (and a disturbing epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya AgEcon
Ashraf, Nava; Gine, Xavier; Karlan, Dean S..
In much of the developing world, many farmers grow crops for local or personal consumption despite export options which appear to be more profitable. Thus many conjecture that one or several markets are missing. We report here on a randomized controlled trial conducted by DrumNet in Kenya that attempts to help farmers adopt and market export crops. DrumNet provides smallholder farmers with information about how to switch to export crops, makes in-kind loans for the purchase of the agricultural inputs, and provides marketing services by facilitating the transaction with exporters. The experimental evaluation design randomly assigns pre-existing farmer self-help groups to one of three groups: (1) a treatment group that receives all DrumNet services, (2) a...

Rural Income Generating Activities in Developing Countries: Re-assessing the Evidence AgEcon
Carletto, Gero; Covarrubias, Katia; Davis, Benjamin; Krausova, Marika; Stamoulis, Kostas G.; Winters, Paul C.; Zezza, Alberto.
This paper contributes to the understanding of the dynamics of developing country rural labour markets by re-evaluating the available evidence on the levels and composition of income sources adopted by rural households in order to understand the relationship between the various economic activities taking place in rural areas and their implications for economic growth and poverty reduction. This is achieved in two parts: First, the paper introduces the Rural Income Generating Activities (RIGA) database, a newly constructed FAO repository of household survey data, income measures and cross-country comparable indicators. Second, using the RIGA database, the paper undertakes a descriptive analysis of the agricultural and non-agricultural sectors of the rural...

Consumption Growth in a Booming Economy: Taiwan 1976-96 AgEcon
McKenzie, David.
Consumption and income have both grown rapidly in Taiwan over the past forty years, with younger birth cohorts experiencing faster growth. The long upward trend in consumption presents a strong challenge to the consumption smoothing predictions of the Permanent Income Hypothesis. We investigate the extent to which consumption theory can account for this trend in an environment where a large majority of households have high savings rates. Household survey data from 1976-96 are used to estimate dynamic pseudo-panel models with inter-cohort heterogeneity. We evaluate the impacts on consumption of migration, mortality, household composition, liquidity constraints, unanticipated aggregate shocks, hyperbolic discounting, habit formation and precautionary saving....

Social Networks in Ghana AgEcon
Udry, Christopher R.; Conley, Timothy G..
In this chapter we examine social networks among farmers in a developing country. We use detailed data on economic activities and social interactions between people living in four study villages in Ghana. It is clear that economic development in this region is being shaped by the networks of information, capital and influence that permeate these communities. This chapter explores the determinants of these important economic networks. We first describe the patterns of information, capital, labor and land transaction connections that are apparent in these villages. We then discuss the interconnections between the various economic networks. We relate the functional economic networks to more fundamental social relationships between people in a reduced form...
