A Characterization of Collective Individual Expenditure Functions

Martina Menon (), Elisa Pagani () and Federico Perali ()

No 20/2012, Working Papers from University of Verona, Department of Economics

Abstract: We examine the properties ensuring that individual expenditure functions, derived within the context of the collective household model, are legitimate individual cost functions. Our curvature results are important for the characterization of collective demand functions as well and for the measurement of inequality within the household.
