The citizens are interested in only two things, drinking milk and watching fireworks. Fireworks cost 1 gallon of milk per unit. People in Galway have identical utility functions Ui(xi, g)=xi+(√g)/20, where xi is the number of gallons of milk per year consumed by citizen i, and g is the number of units of fireworks exploded in the town’s Fourth of July extravaganza. (Private use of fireworks is outlawed.)
