Attribute substitution in household vehicle portfolios

Abstract: Roughly three quarters of vehicles are purchased into multi‐car households. We study whether households are willing to substitute attributes, such as fuel economy, across vehicles within their portfolio. We develop a novel strategy to separately identify idiosyncratic preferences for an attribute from these within‐portfolio effects. Using the universe of household vehicle registration records in California over a 6‐year period, we find that two‐car households exhibit strong substitution across vehicles when fa… Show more

“…First, EVs are heavier than ICEs, which increases the fatality risk from collisions (Shaffer et al 2021). There is also growing evidence of portfolio effects within households (Archsmith et al (2020)) that may cause EVs households to purchase larger vehicles in an attempt to diversify the portfolio of vehicles owned.…”

“…The downward slopes in Panel E imply that older vehicles drive fewer annual miles. This may occur because most households prefer to drive the newer of two vehicles (Archsmith et al 2020) or because the households that own older vehicles have lower driving demand.…”

“…Our work contributes to the broad literature on product complementarities, which has long received attention in economic literature (Hicks and Allen, 1934;Samuelson, 1974). There is also a large related empirical literature allowing for products with interrelated demand (Train et al, 1987;Archsmith et al, 2020;Gentzkow, 2007). Our paper more specifically relates to growing literature on the demand for accessory goods (Liu et al, 2018;Sharma and Mehra, 2021).…”
