Hall argues that any commodity can serve as the base as long as it is (1) sufficiently homogenous and (2) easily measured. However, he claimed that ANCAP was a particularly good choice because the index followed the Consumer Price Index very well from the postwar era up until the year he published the idea, 1982. Hall claims that one possible goal of a commodity standard is to stabilize the cost of living (trying to stabilize all prices is likely unrealistic). To do this, commodities whose value changes in accordance with changes in the cost of living should be chosen as the base.
