Power Against Random Expenditure Allocation for Revealed Preference Tests Per Hjertstrand


This paper proposes new power indices for revealed preference tests. The indices are based on a model of irrational consumption behavior where the consumer randomly allocates a certain fraction of expenditure. The methods allow a researcher to trace out the entire power curve against random
expenditure allocation. The power indices are illustrated on altruistic choices in experimental data.
