Price index is the ratio of the current cost of that basket to the cost in a base year, times 100. Price index in a given year = (cid:3030)(cid:3042)(cid:3046)(cid:3047) (cid:3042)(cid:3033) (cid:3040)(cid:3028)(cid:3045)(cid:3032)(cid:3047) (cid:3029)(cid:3028)(cid:3046)(cid:3032)(cid:3047) (cid:3041) (cid:3034)(cid:3049)(cid:3032)(cid:3041) (cid:3052)(cid:3032)(cid:3028)(cid:3045) Inflation rate = (cid:3041)(cid:3031)(cid:3032)(cid:3051) (cid:3041) (cid:3034)(cid:3049)(cid:3032)(cid:3041) (cid:3052)(cid:3032)(cid:3028)(cid:3045) (cid:3041)(cid:3031)(cid:3032)(cid:3051) (cid:3041) (cid:3043)(cid:3045)(cid:3032)(cid:3049)(cid:3042)(cid:3048)(cid:3046) (cid:3052)(cid:3032)(cid:3028)(cid:3045) (cid:3030)(cid:3042)(cid:3046)(cid:3047) (cid:3042)(cid:3033) (cid:3040)(cid:3028)(cid:3045)(cid:3032)(cid:3047) (cid:3029)(cid:3028)(cid:3046)(cid:3032)(cid:3047) (cid:3041) (cid:3029)(cid:3028)(cid:3046)(cid:3032) (cid:3052)(cid:3032)(cid:3028)(cid:3045) (cid:883)(cid:882)(cid:882) (cid:3041)(cid:3031)(cid:3032)(cid:3051) (cid:3041) (cid:3043)(cid:3045)(cid:3032)(cid:3049)(cid:3042)(cid:3048)(cid:3046) (cid:3052)(cid:3032)(cid:3028)(cid:3045) Directly impacts millions of americans: payments are tied to or indexed to cpi. Amount paid rises or falls when cpi rises or falls. What happens when a good in the cpi basket undergoes unaccounted for quality improvements: a: inflation will be overestimated.
