Designate one year as a base year, making it the benchmark against which years are compared. Problems in measuring the cost of living. Substitution bias: the basket does not change to re ect consumer reaction to changes in relative prices. Consumers substitute toward goods that have become relatively expensive. The index overstates the increase in cost of living by not considering consumer substitution.
