Abstract

Robert McClelland and Marshall Reinsdorf (1999) "Small Sample Bias in Geometric Mean and Seasoned CPI Component Indexes."

In this analysis we compare the finite sample bias (aka small sample bias) of the geometric means index and the 'seasoned modified Laspeyres index ' (hereafter referred to as the seasoned index.) Our tentative conclusion is that the geometric means index has a larger, growing rate of small sample bias while the seasoned index has a smaller, fluctuating bias.
