The results from the random parameter logit estimation indicate that the marginal WTP increases with the duration of the outages, and is higher if the outages occur during weekends and during winter months. Moreover, the random parameter logit model allows us to estimate a sample distribution of WTP and we find a significant unobserved heterogeneity in some of the outage attributes. Given that households have negative welfare effects from outages, it is important that policy makers consider these negative impacts on household utility when regulating the Swedish electricity market.engChoice experimentPower outagesRandom parametersWillingness to payarticle, peer reviewed scientific
