Unit value is a measure of the price of a physical unit of apparent consumption (in this case, a metric ton) in dollars. For a commodity whose apparent consumption is measured in a single physical form, such as copper metal, a simple price series may be used to estimate the unit value. For many commodities, apparent consumption measures more than one form of the commodity. The commodity chromium, for example, includes chromium metal, chromium ferroalloys, and chromite ore in its measurement of apparent consumption. Weighted averages were used in these cases, where the price of each form of chromium was weighted by the amount that each form contributes to apparent consumption. For many commodities, a price series was not available, but total value of exports, imports, and production was reported. Unit values were derived, in these cases, using the physical quantity data for exports, imports, and production. The notes that accompany each mineral commodity worksheet discuss the source of apparent consumption and unit value data and the assumptions made in estimating these data when they were not available from the references. Unit values in these tables are also reported in 1998 (constant) dollars, where the Consumer Price Index for All Urban Consumers was used as the deflator. Constant dollars remove the effect of inflation on the unit value., Moved Permanently. The document has moved here., Часть i-я. Пятокнижие Моисеева.
