This paper is an attempt to analyze the impact of two of India's largest food security interventions - the Public Distribution System (PDS) and the Mid Day Meal Scheme (MDM) - on poverty outcomes and on nutritional intake. This paper offers a simple methodology to take into account the impact of...

Many development programs that attempt to disseminate improved technologies are limited in duration, either because of external funding constraints or an assumption of impact sustainability; but there is limited evidence on whether and when terminating such programs is efficient. We provide...

Food security is a complex and multi-dimensional phenomenon. As such, its measurement may entail and benefit from the combination of both ‘qualitative-subjective’ and ‘quantitative-objective’ indicators. Yet, the evidence on the external validity of subjectivetype information is scarce,...

This module illustrates how poverty can be defined in the context of policy impact analysis. After reporting and discussing the definition of poverty as “the lack of, or the inability to achieve, a socially acceptable standard of living”, it discusses the mono-dimensional and...

This paper compares historical poverty baskets to modern food security and poverty lines.  Changes in the historical baskets and indexing methods are proposed to bring historical studies into better alignment with modern measures as well as with historically based estimates of energy...

A model that allows the estimation of the latent prices of animal proteins, vegetal proteins, fats and carbohydrates that come from staple food is developed. This research opens a path for developing food security models that take into account not only the calories intake but the nutritional...

Economists have long recognized that a household's well-being depends not just on its average income or expenditure, but also on the risks it faces. Hence vulnerability is a more satisfactory measure of (inadequate) welfare than poverty. We measure vulnerability as expected poverty and establish...

For Bangladesh food security was synonymous with achieving self-sufficiency in rice production and stabilization in rice prices. The country has made good progress in increasing rice production through technological progress, facilitated by private sector investment in small scale irrigation....

This paper deals with consumption dynamics and its effects on poverty. An econometric model is proposed in which changes in consumption across time are seen as fluctuations around the level of consumption that each family can sustain in the long term. The advantages of this approach are twofold....
