- ‘Quantitative analysis of public utility functions has long been abandoned.’
- ‘For computational convenience it is assumed that all individuals have the same utility function.’
- ‘‘Everyone has different preferences and utility functions.’’
- ‘According to this model, individuals have a utility function defined over their own consumption.’
