Abstract

"Theories of poverty traps stand in sharp contrast to the view that anybody can make it through hard work and thrift. However, empirical detection of poverty traps is complicated by the lack of long panels, measurement error, and attrition. This paper shows how dynamic pseudo-panel methods can overcome these difficulties, allowing estimation of non-linear income dynamics and testing for the presence of poverty traps. The paper explicitly allows for individual heterogeneity in income dynamics to account for the possibility that particular groups of individuals may face traps, even if the average individual does not. These methods are used to examine the evidence for a poverty trap in labor earnings, income, and expenditure in Mexico and are compared to panel data estimates from a short rotating panel. The results do find evidence of nonlinearities in household income dynamics and demonstrate large bias in the panel data estimates. Nevertheless, even after allowing for heterogeneity and accounting for measurement error, the paper finds no evidence of the existence of a poverty trap for any group in the sample.

Abstract

"The author uses a large household data set from Guatemala to analyze how the receipt of internal remittances (from Guatemala) and international remittances (from the United States) affects the marginal spending behavior of households on various consumption and investment goods. Contrary to other studies, the author finds that households receiving remittances actually spend less at the margin on consumption-food and consumer goods and durables-than do households receiving no remittances. Instead of spending on consumption, households receiving remittances tend to spend more on investment goods, like education, health, and housing. The analysis shows that a large amount of remittance money goes into education. At the margin, households receiving internal and international remittances spend 45 and 58 percent more, respectively, on education, than do households with no remittances. These increased expenditures on education represent investment in human capital. Like other studies, the author finds that remittance-receiving households spend more at the margin on housing. These increased expenditures on housing represent a type of investment for the migrant, as well as a means for boosting local economic development by creating new income and employment opportunities for skilled and unskilled workers.

Abstract

"Empirical evidence suggests that global trade reforms are unlikely to produce analogous results across countries, especially when analyzing their effect on poverty. This implies that the analysis of trade reform on social welfare cannot be generalized and needs to be conducted on a country by country basis. Moreover, even within the same country, geographic areas, households, and individuals are likely to be differentially affected, some of them benefiting more than others, while others might lose. With this in mind, the author provides a quantitative estimate of the effect on Mexican households from the implementation of the Doha development agenda. His analysis uses a two-step approach for which changes in prices and factors are estimated through a CGE model (GTAP) and then mapped into the welfare function of the household using household survey data. The empirical approach the author uses aims to measure the impact of Doha implementation by tracing changes in the household prices of goods and factors and their impact on household welfare, taking particular account the role of domestic price transmission. The findings suggest that multilateral trade liberalization alone would have a negative effect on Mexican households, even though very small. However, when the implementation of the Doha development agenda is complemented by domestic policies aimed at increasing productivity and improving domestic price transmission, the overall effects become positive. The results point to the importance of domestic price transmission in determining the variance of the effects across households. "--World Bank web site.

Abstract

"This paper explores an empirical methodology to assess the impacts of trade reforms on household behavior in developing countries. It focuses on consumption and income responses: when price reforms take place, households modify consumption and production decisions and local labor markets adjust. The paper proposes a joint estimator of demand and wage price elasticities from survey data. The method uses an empirical model of demand to extract price information from unit values, and uses this information to estimate the response of households to price reforms. By correcting unit values for quality effects and measurement error, the method overcomes the problem of the endogeneity of unit values. By endogeneizing household income, the model corrects potential biases in the estimation of own- and cross-price elasticities in consumption. The paper applies the method to an expenditure and income survey for rural Mexico. It shows that the corrections suggested in this paper are empirically important. In particular, it shows that allowing for consumption and income responses is a key element of an accurate empirical assessment of trade policy. "--World Bank web site.
