The Cut and the Chain
Walk the price of meat from farm to wholesale to grocery retail — beef, pork, broiler, monthly since 1970, in cents per pound of retail equivalent. The reveal: almost the entire farm-to-retail markup lives in the wholesale→retail leg — downstream of where a kitchen buys. Retail here is USDA ERS national-average grocery retail, never a delivered, invoice, or menu price.
Schema — raw JSONL: one record per line {year, month, data_item, value, units}; monthly 1970–2025; value in cents per pound of retail equivalent. Derived JSON: proteins[] with chain{net_farm_value, wholesale_value, retail_value, farm_to_wholesale_spread, wholesale_to_retail_spread, farm_to_retail_spread}, downstream_markup_share (percent), and monthly series{net_farm_value, wholesale_value, retail_value}.
The national-average price chain, latest month (2025-12) — cents per pound of retail equivalent. Retail is USDA ERS national-average grocery retail: not a delivered, wholesale-invoice, or menu price. A documented spread, never a forecast.
USDA ERS Meat Price Spreads — farm → wholesale → retail, 2025-12. "Downstream" = the share of the farm-to-retail spread that falls in the wholesale→retail leg.
