Inspired by the recent literature on aggregation theory, this paper introduces HITS, a semiparametric model of consumer demand that allows for diversity in tastes. The strong variation of budget shares observed across income groups has two possible origins: the individual income effect, and...

This paper investigates the determinants of value and growth investing in a large administrative panel of Swedish residents over the 1999-2007 period. The authors document strong relationships between a household's portfolio tilt and the household's financial and demographic characteristics....
