The future of food demand: Evidence from a global meta-analysis and trend projections

Understanding how food demand responds to income and price changes is essential for anticipating global food needs and expected consumption patterns, and for designing effective food policies. Two key parameters for this are the income elasticity of demand—the percent change in consumption in response to a percent change in people’s income; and the price elasticity of demand—the percent change in consumption in response to a percent food price change. These are essential inputs in a wide range of economic models.
