False positives or hidden dimensions: what can monetary and multidimensional measurement tell us about child poverty in Vietnam?

A widely used division between poverty measures based on conceptual underpinnings and analytical outcomes is that of monetary versus multidimensional measures. Comparisons of the use and outcomes of the two methods have shown that they predominantly provide different pictures of poverty in terms of size, rank and group. This article contributes to the long-standing and ongoing debate on poverty measurement by comparing the use of monetary and multidimensional poverty approaches, with a special focus on children in Vietnam and extending the empirical analysis beyond conventional methods. In addition to investigating whether poverty outcomes or groups of identified poor children differ when using the two different poverty measures, we also investigated the drivers underlying these differences. Findings confirm a considerable degree of mismatch: both poverty measures proved to be inadequate proxies for the other and factors underlying the identification by either one or both of the measures differed.
