The degree of mobility in incomes is often seen as an important measure of the equality of opportunity in a society and of the flexibility and freedom of its labor market. But estimation of mobility using panel data is biased by the presence of measurement error and non-random attrition from the...

This paper reviews the progress made in the literature toward defining and measuring the affordability of utilities. It highlights the relative merits of alternate affordability metrics; the practical challenges to their operationalization, including the underlying data requirements; and their...

This paper brings together some of the empirical work conducted by IFPRI researchers which investigates linkages among the degree of consumption insurance, households'vulnerability to poverty, and household use of formal and informal coping mechanisms using the same empirical approach in five...

Practitioners from different disciplines use different meanings and concepts of vulnerability, which, in turn, have led to diverse methods of measuring it. This paper presents a selective review of the literature from several disciplines to examine how they define and measure vulnerability. The...

Empirical evidence indicates that in many developing regions, the extreme poor in more marginal land areas form a"residual"pool of rural labor. Structural transformation in such developing economies depends crucially on labor and land use decisions of these most-vulnerable populations located on...

The developing world is experiencing substantial environmental change, and climate change is likely to accelerate these processes in the coming decades. Due to their initial poverty, and their relatively high dependence on environmental capital for their livelihoods, the poor are likely to...

This paper uses a rural household survey dataset collected in 2006 and 2008 to investigate the impact of a market-based land resettlement project in southern Malawi. The program provided a conditional cash and land transfer to poor families to relocate to larger plots of farm land. The average...

Typically the tools available for redistribution are price subsidies and direct cash transfers. Conventional economic theory indicates that the efficiency loss is minimized if cash transfers are used instead of price subsidies. But in almost all economies, including advanced economies, price...

The author uses household-level data from a nationally representative survey to analyze the impact of nonfarm income on income inequality in rural Egypt. After pinpointing the importance of nonfarm income to the rural poor, the author decomposes total rural income among five sources, nonfarm,...

The author uses a simulation model to quantify the impact on income distribution of having a neutral social security program that is fully funded replace a progressive social security program that redistributes income toward the poor but is financed by a pay-as-you-go method. He finds that if...
