Undernourishment is still widespread in Tanzania, while obesity is becoming an issue of magnitude similar to undernutrition in the country. In this paper we examined the impact of an increase in maize prices on the nutritional status of Tanzania's adult population. We found that undernutrition...

This paper investigates the effect of price variations on the diet composition in Britain. It describes the dynamics of food demand in relation to food prices over time using data from the British National Food Survey (NFS) covering the period 1975-2000. Demand elasticities with respect to price...

We study the consumer response to the extension of a perishable food item’s shelf life. We develop a theoretical model that describes a utility maximizing consumer planning for an uncertain number of consumption occasions. This model permits prediction of both changes in the purchase and waste...

Measuring food waste at the individual household level has been nearly impossible because comprehensive, current data on uneaten food do not exist. By using food acquisition data, this article employs a new approach to estimating household-level food waste via a stochastic production frontier...

This paper investigates household food waste in the context of inefficient food production. Food waste is typically defined as the proportion of edible food that goes unconsumed, whereas inefficiency is measured by a household's inability to reach some technically efficient production frontier....
