Stated car choice observations by US car buyers

Description

Data from Helveston et al. (2015) containing 448 stated choice observations from Chinese car buyers and 384 stated choice observations from US car buyers. Conjoint surveys were fielded in 2012 in four major Chinese cities (Beijing, Shanghai, Shenzhen, and Chengdu), online in the US on Amazon Mechanical Turk, and in person at the Pittsburgh Auto show. Participants were asked to select a vehicle from a set of three alternatives. Each participant answered 15 choice questions.
