The all-food CPI reflects price movements at supermarkets and other food-at-home retailers as well as price changes at fast food outlets, restaurants, and other away-from-home places. While prices in these two markets typically move in the same direction, food-away-from home prices are less volatile. Inputs such as wages for restaurant workers, rents, and advertising play a larger role in shaping away-from-home prices than at-home prices. Costs for these inputs rise and fall less sharply than commodity and fuel prices, lessening price volatility for food away from home.
