Migration to the United States and Mexican rural development: a case study

An analysis of the impact of migration to the United States on the sending community and on the labor market in the receiving country is presented based on a case study of Las Animas, Mexico. "As the community becomes increasingly involved in migration, tendencies can be identified regarding changing migration patterns, class differentiation among villagers, impact of migration on village economy, and the changing role of Mexican workers in California labor markets. Results indicate the importance of social networks in determining the outcome of migration; while migration is individually rational, it is a factor of stagnation for village economy, and it helps reproduce segmented California labor markets."     

Household Behavior with Imperfect Labor Markets

A household model with differential asset endowments and idiosyncratic transactions costs in accessing labor markets is developed to (1) explain membership of farm households to alternative labor regimes (sellers, employers, or self-sufficient in labor), (2) test for recursivity between production and consumption decisions selectively by labor regime, and (3) identify the determinants of differential labor productivity across labor regimes. The model is applied to a 1994 household survey of the Mexican land reform sector.     

Making Conditional Cash Transfer Programs More Efficient: Designing for Maximum Effect of the Conditionality

Conditional cash transfer programs are now used extensivelyto encourage poor parents to increase investments in their children’shuman capital. These programs can be large and expensive, motivatinga quest for greater efficiency through increased impact of theprograms’ imposed conditions on human capital formation.This requires designing the programs’ targeting and calibrationrules specifically to achieve this result. Using data from theProgresa randomized experiment in Mexico, this article showsthat large efficiency gains can be achieved by taking into accounthow much the probability of a child’s enrollment is affectedby a conditional transfer. Rules for targeting and calibrationcan be made easy to implement by selecting indicators that aresimple, observable, and verifiable and that cannot be manipulatedby beneficiaries. The Mexico case shows that these efficiencygains can be achieved without increasing inequality among poorhouseholds.     

GROWTH, POVERTY, AND INEQUALITY IN LATIN AMERICA: A CAUSAL ANALYSIS, 1970–94

Taking advantage of consistent poverty and income inequality data for 12 Latin American countries between 1970 and 1994, we analyze the determinants of changes in the incidence of urban and rural poverty and in Gini coefficients over spells of years, stressing in particular the role of aggregate income growth. We find that income growth reduces urban and rural poverty but not inequality. We also find that income growth is more effective in reducing urban poverty if the levels of inequality and poverty are lower, and the levels of secondary education higher. We show that there is an asymmetry in the impact of growth on poverty and inequality, with recession having strong negative effects on both poverty and inequality. Since growth does not reduce inequality, economic cycles create ratchet effects on the level of inequality. However, post-structural adjustment growth is quite effective at reducing poverty, particularly if inequality is low.     

Genetically Modified Crops, Corporate Pricing Strategies, and Farmers' Adoption: The Case of Bt Cotton in Argentina

This article analyzes adoption and impacts of Bt cotton in Argentina against the background of monopoly pricing. Based on survey data, it is shown that the technology significantly reduces insecticide applications and increases yields; however, these advantages are curbed by the high price charged for genetically modified seeds. Using the contingent valuation method, it is shown that farmers' average willingness to pay is less than half the actual technology price. A lower price would not only increase benefits for growers, but could also multiply company profits, thus, resulting in a Pareto improvement. Implications of the sub-optimal pricing strategy are discussed.     

The class basis of agricultural growth

An explanation of the stagnation in agricultural production relative to effective demand and of the widespread malnutrition and hunger in the countries bordering the Caribbean is provided, using the basic categories of political economy. The authors show that the disappearance of peasants as a class of producers and their reduction to the role of a semiproletarian labour reserve explains the crisis in many food crops as well as extensive rural poverty. They also show that the dynamism of capitalist agriculture is often biased against wage-foods as a result of cheap food policies and directed instead toward the production of exportables, inputs for industry and luxury foods.     

Social articulation as a condition for equitable growth

A formal model is developed to establish the structural conditions that result in growth being progressive or regressive on the personal distribution of income. These conditions include (1) intersectoral investment priorities between wage goods and luxuries, and (2) the state of the levels and distribution of incomes which determines the social origin of demand for different sectors of the economy. The particular combinations of investment and income structures that result in equalizing (social articulation) or unequalizing growth (social disarticulation) are derived. We show empirically that the structural conditions that allowed rapid but unequalizing growth in Brazil between 1968 and 1977 were those of social disarticulation.     

Designing credit agent incentives to prevent mission drift in pro-poor microfinance institutions

Credit agents in microfinance institutions (MFIs) must be given incentives to acquire information on potential borrowers and select them in accordance with the MFI's objectives. We show that while giving incentives has no cost in for-profit MFIs, it is costly in pro-poor MFIs: When repayment and wealth are positively correlated, a pro-poor MFI cannot obtain the selection of poor clients in the proportion it wishes with incentives based solely on repayment. It then becomes necessary to audit the share of very poor borrowers selected by an agent in order to provide the latter with adequate incentives. When audit costs are large, pro-poor MFIs may have to forego selection on wealth — and use other targeting devices such as working in impoverished geographical locations. Driven by donor concerns with ‘mission drift’ away from the poor, audits on the wealth status of clients have been introduced at the level of MFIs. We show that introducing pro-poor incentives requires extending such audits to the level of credit agents.     

Household Behaviour under Market Failures: How Natural Resource Management in Agriculture Promotes Livestock Production in the Sahel

Improved water harvesting and soil erosion control using theremarkably simple practice of contour stone bunding is shownto increase grain yields by 41% in low rainfall regions of BurkinaFaso. Empirical results show that yield increases in food cropshelp food-buying farm households import-substitute in food consumption,reduce livestock production and increase seasonal migration,which is more compatible with seasonal agriculture than withthe yearlong livestock activity. Self-sufficient households,by contrast, can take advantage of higher yields to free resourcesfrom food production and allocate these to expand their livestockeconomy, thus benefiting more from the region's comparativeadvantage. We also show that greater effectiveness in cooperationin the management of common property resources helps increaseincome derived from livestock for all categories of households.However, not all forms of cooperation are effective. When cooperationis only formal, individual activities such as crops, non-agriculturalemployment and seasonal migration are pursued, as opposed tolivestock activities that rely on effective community managementof common property resources.
