Food-Price Inflation and Household Welfare: Transmission, Distributional Effects, and Policy Responses

Food prices matter for welfare far more than their weight in a headline consumer price index suggests. Because poorer households spend a much larger share of their budgets on food, and because the staples they rely on have few close substitutes, a given rise in food prices acts like a regressive tax that falls hardest on the bottom of the distribution. This article develops a compact analytical framework for measuring the welfare cost of food-price increases, reviews how shocks travel from world markets to household budgets, and summarises empirical evidence from the major price surges of 2007–08, 2010–11 and 2021–23. The central findings are threefold: (i) first-order losses are approximately the product of the food budget share and the rate of food inflation, so they are largest for the poorest net buyers; (ii) the sign of the effect for rural households depends on whether they are net buyers or net sellers of food and on how wages adjust; and (iii) the costs extend beyond current consumption to nutrition and human-capital accumulation. The article closes with design principles for policy, emphasising targeted and scalable transfers over blanket price controls, and a research agenda.
