A price index (plural: “price indices” or “price indexes”) is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a given region, during a given interval of time.
Sometimes, they can be useful in helping to guide investment.Some notable price indices include: No clear consensus has emerged on who created the first price index.The earliest reported research in this area came from Welshman Rice Vaughan who examined price level change in his 1675 book A Discourse of Coin and Coinage.Vaughan wanted to separate the inflationary impact of the influx of precious metals brought by Spain from the New World from the effect due to currency debasement.Vaughan compared labor statutes from his own time to similar statutes dating back to Edward III.He argued on behalf of the Oxford students and published his findings anonymously in a volume entitled Chronicon Preciosum.
would be a reasonable measure of the price of the set in one period relative to that in the other, and would provide an index measuring relative prices overall, weighted by quantities sold.Of course, for any practical purpose, quantities purchased are rarely if ever identical across any two periods.As such, this is not a very practical index formula.These statutes set wages for certain tasks and provided a good record of the change in wage levels.Vaughan reasoned that the market for basic labor did not fluctuate much with time and that a basic laborers salary would probably buy the same amount of goods in different time periods, so that a laborer's salary acted as a basket of goods.Vaughan's analysis indicated that price levels in England had risen six to eightfold over the preceding century.
