Understanding the relationship between income and food demand is critical for designing policies aimed at addressing under-nutrition and food security in developing countries. By and large, the literature has focused on the relationship between income and calorie consumption (i.e. calorie-income elasticities), while only a few studies have considered the nutrient composition (e.g. fats, proteins, carbohydrates) of calorie consumption. This distinction is important for understanding the interactions between income growth, food consumption, nutrition and health. Given the dominant focus of the literature on calorie consumption, as opposed to nutrient consumption, it is necessary to consider the differences in the calorie-income elasticities across different types of food as well as their associated nutrient consumption. This approach would present a holistic view of the relationship between income and food demand, and would better inform policy decisions on nutrition and food security.
The aim of this project is to provide a meta-analysis of existing studies of food demand, focussing on the relationship between income and calorie and nutrition consumption in developing countries, in particular African countries. Meta-analysis provides an objective approach to review empirical literature through the use of statistical techniques, and has been more prominently applied in psychology and medical sciences but has also more recently gained popularity in economics.
This project runs from October 2014 to May 2015 and is funded by the European Commission Joint Research Centre, Institute for Prospective Technological Studies (JRC-IPTS)
