While the empirical evidence suggests attenuation bias, our theoretical exposition and simulations demonstrate that upward bias and sign reversal effects are also possible. …”

Gender, household behavior, and rural development por Doss, Cheryl, Quisumbing, Agnes R.

“…Conventional wisdom, rooted in the unitary theory of the household, held that households are groups of individuals who have the same preferences and fully pool their resources (Becker 1981). Accumulating empirical evidence has shifted this concept of the household in which households decide “as one” to a “collective” model in which individual household members may have different preferences, may not completely pool resources, and may bargain over outcomes in both production and consumption (Haddad, Hoddinott, and Alderman 1997).…”
