Working Wives and the Marginal Propensity to Consume Food Away from Home
研究发现，全职工作妻子的收入并未提高家庭外出就餐的边际消费倾向，而兼职妻子、子女收入、资产收入和转移支付则显著提高该倾向，且白人的外出就餐支出和边际消费倾向高于非白人。
Abstract Contrary to predictions from the new household economics theory and heuristic thought, income earned by wives working full time did not increase the marginal propensity to consume food away from home. Tobit estimates of the same propensity from other income sources in married U.S. households in 1978 showed that income earned by part‐time working wives and children, asset income, and transfer payments increased this propensity above that from husband's labor income. Whites had higher expenditures, higher marginal propensities to consume, and lower income elasticities for food away from home than nonwhites.
