1959—1985年通胀测度中的替代偏误分析
The authors analyze the substitution bias in Laspeyres-type price indexes, using 101 c ommodities. They construct the tightest theoretical bounds on the cos t-of-living index using nonparametric methods and also construct supe rlative price indexes. Using nonparametric methods, the authors find homothetic preferences are consistent with the data. Sensitivity test s indicate that this result is not vacuous. Under this hypothesis, th e bias is between 0.22 and 0.14 percent per…
