How can economists estimate consumption parameters by income classes? The approach used in this paper combines price elasticities estimated from aggregated market data and income-class-specific elasticities derived from household expenditure surveys using Slutsky relationships to calculate income-class-specific price elasticities. The approach was applied to estimate income-class-specific price elasticities for major agricultural commodities consumed in Jamaica.
