Opis

The primary purpose of this study is to produce household specific price indexes for consumer units or households living in the United States in the early 1990s. This paper is a report on how these household specific indexes were created. With household specific indexes, households are assumed to have nonhomothetic preferences, so changes in prices involve relative price changes between different sets of commodities and the resulting indexes will differ systematically between different households. We examine several different approaches to construct these indexes. Our indexes are based on internal U.S. Consumer Expenditure Survey (CEX) data for 1990-91 and Bureau of Labor Statistics Consumer Price Index (CPI) data from winter 1981, 1987, and 1991. Our base period is 1990-91. Using these data we produce Paasche type household specific indexes. In addition we propose an alternative definition of total expenditures, based on the CPI market basket commodity space, to be used for welfare analysis. Our underlying motivation for conducting this study was to compare real welfare inequality in Spain and the U.S. in the 1980s for another study (Garner et al. forthcoming 1997). Because of this comparison, we were somewhat restricted in our approach.
