Highlights • Data on consumer preferences for electric vehicles (EVs) is collected using stated choice experiment in different cities in China. • Critical service factors and government policies are identified, alongside product attributes, as influencing consumer preferences for EVs in China. • Chinese consumers have the highest willingness to pay to obtain a free license for EVs (106,144 RMB on average) and to be permitted to install a home charging post (91,039 RMB on average). • Our findings imply that the perceived level of inconvenience is a key factor when consumers are considering switching from conventional petrol vehicles to EVs.

Research Highlights: This paper introduces the discrete choice paradigm of Random Regret Minimization (RRM) to the field of health economics The combined use of RRM and Random Utility Maximization (RUM) models provide useful behavioural insights on choice Whilst the RUM is suitable for calculating welfare estimates, the RRM highlights how anticipated regret affects choices We find that the choices of overweight or obese respondents and smokers are more likely to conform to the RUM approach We also find that the choices of people in good health and with higher education are more likely to reflect the RRM approach AbstractPage 2 of 31 A c c e p t e d M a n u s c r i p t This paper introduces the discrete choice model-paradigm of Random Regret Minimization (RRM) to the field of health economics. The RRM is a regret-based model that explores a driver of choice different from the traditional utility-based Random Utility Maximization (RUM). The RRM approach is based on the idea that, when choosing, individuals aim to minimize their regret -regret being defined as what one experiences when a non-chosen alternative in a choice set performs better than a chosen one in relation to one or more attributes. Analysing data from a discrete choice experiment on diet, physical activity and risk of a fatal heart attack in the next ten years administered to a sample of the Northern Ireland population, we find that the combined use of RUM and RRM models offer additional information, providing useful behavioural insights for better informed policy appraisal.Keywords: Random Regret Minimization; Random Utility Maximization; dietary choices; physical activity; coronary heart disease risk; behavioural economics.

Since the first applications of DCE in health economics to value patient experiences (Ryan and Hughes, 1997;Ryan, 1999), this technique has become widely used to investigate a wide range of policy questions (Ryan et al., 2008 Evidence from previous studies suggests that regret can be an important factor in both medical decision making (Smith, 1996;Djulbegovic et al. 1999 andSorum et al. 2004) and personal healthcare decisions (Brehaut et al., 2003 andZiarnowski et al., 2009), particularly when the outcome of the choice may be unfavourable. Smith (1996) explored the concept of regret in healthcare decision making from the patient's viewpoint, arguing that valuation techniques based on the utility theory, such as QALYs, will not necessarily reflect the true preferences of the individual. Ziarnowski et al. (2009) found that anticipated regret played an important role in the decision to vaccinate adol...
