The document describes a model of the pork commodity cycle involving hogs, pork inventory, price, supply and demand. Key variables include: hogs slaughtered per month (4 million), pork inventory held by butchers (2 weeks worth), normal pork consumption per person (3 lbs/month), and normal hog price ($0.30/lb). The model equilibrium is achieved when initial pork inventory allows supply and demand to balance out. The model responds to a 10% reduction in hog slaughter by increasing pork prices and reducing inventory, and to a 10% increase in pork consumption by decreasing prices and increasing inventory to balance supply and demand.
