We review the origins of the dollar-a-day poverty line, discuss historical poverty and inequality trends, and forecast poverty rates until 2030 using a new fractional response approach. Three findings stand out. First, global poverty reduction since 1981 has been rapid but regional trends are...

Do remittances and social assistance have different impacts on household expenditure patterns While two separate strands of literature have looked at how social assistance or remittances have been spent, few studies have compared them directly. Using data from a nationally representative...

Forced migration, often resulting from violent conflict, imposes large economic costs on both sending and receiving countries, on those agencies that coordinate humanitarian services and most importantly upon the forced migrants themselves. Programs encouraging the return of refugees are...

This paper deals with the problem of selecting the unit of analysis in multidimensional poverty analyses, which is a central decision to take, both from academic and normative points of view. The paper compares the results of an individual-level Multidimensional Poverty Index for Chile,...

We derive a parametric formula of the Watts' poverty index for the bivariate lognormal distribution of price indices and nominal living standards. This enables us to analyze the contributions of price and nominal living standard distributions to poverty, to estimate poverty when only means and...

Spatial price dispersion varies because of climatic fluctuations, marketimperfections, economic growth or economic policies. These variations areoften neglected in poverty studies.In this paper, we propose a simple simulation formula to assess the effecton poverty of a change in the spatial mean...

This study explores the influence of vulnerability on migration intentions within the context of Afghanistan. While it is commonplace to conceptualize migration as being driven by certain economic-related factors, it is reasonable to assume that in an insecure setting like Afghanistan the...

We show under lognormality that, when the Gini coefficient is stable over time, defining the poverty line as a fraction of a central tendency of the living standard distribution restricts the evolution of the poverty measures to be stable. That is, poverty does not change if the Gini coefficient...

It is not known to what extent welfare measures result from seasonal and geographical price differences rather than from differences in living standards across households. Using data from Rwanda in 1983, we show that the change in mean living standard indicators caused by local and seasonal...
