PARETO IMPROVEMENT: Based on the Pareto efficiency criterion, the notion that an action improves efficiency if it is possible for one person to benefit without anyone else being harmed. A Pareto improvement is possible if the economy has idle resources or market failures. With idle resources, more production is possible to help some without hurting others. With market failures, corrective actions can eliminate deadweight loss that can then be use for benefits economy-wide. A contrasting condition for attaining efficiency is the Kaldor-Hicks improvement.

                           CONSUMER PRICE INDEX FOR URBAN WAGE EARNERS AND CLERICAL WORKERS: An index of prices of goods and services typically purchased by urban wage earners and clerical workers. This carries the official abbreviation CPI-W to distinguish it from its more famous sister index CPI-U, which is the standard Consumer Price Index for All Urban Workers, (commonly abbreviated simply as CPI). Like the standard CPI, the CPI-W is compiled and published monthly by the Bureau of Labor Statistics (BLS), using price data obtained from an elaborate survey of 25,000 retail outlets and quantity data generated by the Consumer Expenditures Survey. The CPI-W is a continuation of the original CPI developed early in the 1900s to provide cost-of-living adjustment information to wage-earning workers (which is why the Bureau of LABOR Statistics oversees consumer PRICE indexes). Because the original CPI (now CPI-W) was based on goods and services purchased by wage-earning workers, it was replaced by the newer CPI-U in 1978 to provide a broader, more comprehensive measure of the economy's price level. In particular, the newer CPI-U includes the prices of goods and services purchased by about 80 percent of the non-institutionalized population while the older CPI-W includes about only 32 percent.While the CPI-U is the broader, and presumably more accurate, measure of the macroeconomy's price level, the CPI-W is not a bad measure. The two indexes do tend to move in tandem. For example, the more comprehensive CPI-U for December 2003 is 184.3 while the narrower CPI-W has a value of 179.9. Over two decades (from the 1982-84 base period to 2003), the two indexes differed by only 4.4 index points (or 2.5 percent); not perfect, but not too bad, either.
