The paper analyzes the relevance and validity of the economic surplus concept for consumers receiving their income in commodities. For these consumers, such as farmers in developing countries, it is shown that the measure of welfare gains or losses via the area under the Marshallian demand and supply curves may lead to a considerable error. The paper provides boundaries for the error of approximation as a function of the share of the product in the consumer's budget and the income elasticity of demand.
