Abstract
Static economic models based on complete demand systems are inadequate for estimating unconditional equivalence scales; in order to capture the effects of demographic changes on consumer behaviour, a life-cycle dynamic model is taken into account. In literature, studies have presented and evaluated longitudinal equivalence scales and intertemporal cost of children but these cannot be applied in practice when equivalence scales are utilised in poverty or income distribution analyses. This paper proposes intratemporal equivalent income scales, which are within period index numbers incorporating intertemporal consumer behaviour.
