This paper introduces a generalisation of Roy's Identity and Shephard's Lemma which is applicable where the resource constraining expenditure level of a consumer's utility maximisation problem is not observable but is replaced by some observable proxy variable such as conditional expenditure. Implications for testing for Slutsky symmetry and separability are explored.
