Using data extracted from BLS Consumer Expenditure Surveys between 2009 and 2012, we estimated a probit model concerning the decision made by household heads whether to purchase food items and nonalcoholic beverages from vending machines over a consecutive 2-week period. Key drivers associated with this decision are household income; urbanization; marital status; region; year; age; education level; hours worked; ethnicity; and expenditures made on potato chips and other snacks, candy and chewing gum, food away from home (excluding those made at vending machines), cola drinks, and tobacco products.
