(Online) Presentation at EAERE
I gave a presentation titled “An information search approach to discrete choice experiments” at the EAERE conference in Berlin. Well, the conference was not in Berlin this year, but was hosted online because of COVID-19. The title of the presentation is the same as the one presented at ICMC in August last year, but new in this presentation is that we have the acual data, which was gathered in January.
Presentation at ENVECHO in Verona
I gave a presentation at the Environmental Choice workshop in Verona, Italy. This post is copied with permission from ACRG. Abstract When we analyze how people make choices, we assume taht they are rational utility maximizers. This assumption implies that people have full knowledge of their preferences, complete information about all available alternatives and an infinite ability to make trade-offs between them. These basic assumptions of economics allow us to make consistent predictions and derive welafare estimates.
Poster presented at LEEPin2019 in Exeter
I gave a poster presentation titled: “The effect of device experience and time of day on stated preferences” at the LEEPin2019 Conference on 24th - 26th of June 2019 at the University of Exeter. The working paper, on which the poster is based, is concerned with the response quality of people answering stated preference surveys on their mobile phones compared to a desktop computer. We use the number of surveys a given respondent has answered on each device as a proxy for experience answering surveys on a particular device.
Presentation at ICMC2019 in Kobe
I gave a presentation at the International Choice Modeling Conference (ICMC) in Kobe. The title of the presentation was “An information search approach to discrete choice analysis”. This post is copied with permission from ACRG. Abstract As choice modelers we observe decision makers’ choices among competing alternatives, and we try to come up with a model that best describes the observed choice behavior. The economic model of the rational utility maximizer is still pervasive.
Seminar with HERU in Aberdeen
I was invited to give a seminar in the Health Economics Research Group (HERU) seminar series in Aberdeen on the 31st of May 2019. The title of the talk was: “The search for something better - A consideration set model”. The role that information search plays in economic decision making has long been recognized. The seminar focused on how the search for new information about alternatives plays an important part in how consideration sets are formed, i.
Paper presented at the World Congress for Environmental and Resource Economists
I presented the working paper “Assessing the impact of ‘professional’ respondents using an integrated choice and latent variable model” at the 6th World Congress for Environmental and Resource Economists in Gothenburg. The paper addresses a concern among stated preference practioners relying on online panels to gather data, that some panel members may have substantial experience with answering surveys and that they are “in it for the money”. While not inherently bad or irrational, if these respondents are motivated only by the monetary compensation, and engage in simplifying survey behavior to obtain the compensation with the least amount of effort, then this may lead to poorer data quality.
