As American families gathered for Thanksgiving dinner, the annual American Farm Bureau Federation survey provided an interesting study in agricultural price dynamics. The average cost of a traditional Thanksgiving dinner for ten slipped five per cent to $58.08, yet the cost of eggs surged by more than fifty per cent, driven by a virulent resurgence of avian influenza.

The Anatomy of Micro Supply Shocks

The agricultural survey illustrates the fundamental limitation of aggregate consumer price metrics: while broad food disinflation has brought welcome relief to consumer ledgers, idiosyncratic biological and climatic supply shocks can instantly re-inflate essential basket items. Monetary policy can discipline aggregate demand, but it cannot vaccinate poultry flocks against viral outbreaks.

The Thanksgiving dinner survey highlights the uneven nature of post-pandemic disinflation, proving that supply shocks can easily derail consumer sentiment even as broad inflation recedes.
