| This study examines whether there is spatial integration between and within paddy markets in the North and South of Vietnam. The empirical model developed uses estimates of transfer costs to generalize Ravallions model of spatial market integration to allow for threshold effects. A sequential testing strategy is used to test for market segmentation, the number of thresholds, long-run integration, informational efficiency, and the Law of One Price within an error-correction framework. We find no threshold effects and weak evidence of paddy market integration between northern and southern Vietnam. There is, however, evidence of both threshold effects and stronger market integration within the Red and Mekong River deltas. Whenever price spreads exceeds... |

| Information on the spatial distribution of poverty is particularly useful in designing geographically targeted programs to address regional disparities—a matter of high priority for many countries. Until recently, most developing countries were forced to design these programs based on rough indicators of poverty or on the results of household budget surveys, which typically generate poverty estimates for a limited number of regions. In the late 1990s, a new approach was developed combining census data and household budget survey results to generate poverty estimates for small areas such as districts, allowing the construction of “poverty maps.” A1998 IFPRI study in Vietnam was one of the first to experiment with this approach. A similar method was... |

| Spatially disaggregated maps of the incidence of poverty can be constructed by combining household survey data and census data. In some cases, however, statistical authorities are reluctant, for reasons of confidentiality, to release household-level census data. This paper examines the loss in precision associated with using aggregated census data, such as village- or district-level means of the data. We show analytically that using aggregated census data will result in poverty rates that are biased downward (upward) if the rate is below (above) 50 percent and that the bias approaches zero as the poverty rate approaches zero, 50 percent, and 100 percent. Using data from Vietnam, we find that the average absolute error in estimating provincial poverty rates... |

| This paper combines household survey and census data to construct a provincial poverty map of Vietnam and evaluate the accuracy of geographically targeted anti-poverty programs. First, the paper estimates per capita expenditure as a function of selected household and geographic characteristics using the 1998 Vietnam Living Standards Survey. Next, these results are combined with data on the same household characteristics from the 1999 Census to estimate the incidence of poverty in each province. The results indicate that rural poverty is concentrated in ten provinces in the Northern Uplands, two provinces of the central Highlands, and two provinces in the Central Coast. Finally, Receiver Operating Characteristics curves are used to evaluate the... |
