The Impact of Demographic Variables on Expenditures for Food Away From Home

Whereas considerable effort has been expended in prior research in discussing the appropriateness of alternative measures of income in expenditure studies, this paper looks in depth at the impact of incorporating a broad range of demographic variables in the expenditure analysis. Food expenditures away from home are used to analyze the additional gains in explanatory power and the impact of demographic variables on income elasticities. Considerable divergence of results is found under the alternative measures of income.
