Poverty estimates based on cross-section data provide static snapshots of poverty rates. Although a time series of cross-section data can offer some insights into poverty trends, it does not allow for an assessment of dynamics at the household level. Such a dynamic perspective on poverty...

Little research currently exists on a vulnerability line that distinguishes the poor population from the population that is not poor but that still faces significant risk of falling back into poverty. This paper attempts to fill this gap by proposing vulnerability lines that can be...

Obtaining consistent estimates on poverty over time as well as monitoring poverty trends on a timely basis is a priority concern for policy makers. However, these objectives are not readily achieved in practice when household consumption data are neither frequently collected, nor constructed...

Panel data conventionally underpin the analysis of poverty mobility over time. However, such data are not readily available for most developing countries. Far more common are the"snap-shots"of welfare captured by cross-section surveys. This paper proposes a method to construct synthetic panel...

Movements in and out of poverty are of core interest to both policymakers and economists. Yet the panel data needed to analyze such movements are rare. In this paper, the authors build on the methodology used to construct poverty maps to show how repeated cross-sections of household survey data...

Movements in and out of poverty are of core interest to both policymakers and economists. Yet the panel data needed to analyze such movements are rare. In this paper we build on the methodology used to construct poverty maps to show how repeated cross-sections of household survey data can allow...

This paper is concerned with the derivation of a welfare indicator for households from consumption data. It examines, illustrating with reference to data for ecuador, several of the steps involved in contructing consumption aggregates and highlights some of the principles which should guide the...

Governments and international development agencies have intensified efforts to promote small-scale enterprises as an engine of propoor growth. In Brazil, however, small-scale industries may also be responsible for the bulk of air pollution emissions. Although employees of polluting small-scale...

Communities differ in important ways in their needs, capacities, and circumstances. Because central governments are not able to discern these differences fully, they seek to achieve their policy objectives by relying on decentralized mechanisms that use local information. Household and...

Important differences exist between communities with respect to their needs, capacities, and circumstances. As central governments are not able to discern these differences fully, they seek to achieve their policy objectives by relying on decentralized mechanisms that use local information....
