This note proposes a decomposition of the familiar scalar multivariate risk premium into components which can be easily interpreted in the context of consumer theory. The premium under consideration is the standard one used to ascertain the impact of price and income risk on consumer welfare. This proposed premium decomposition allows for a more intuitive identification of the detrimental and beneficial effects that arise from income and price risk. As an illustrative example, this decomposition is used to ascertain the welfare effects arising from the price fluctuations experienced by UK households over the period 1963–97.
