We employed three surveys to obtain in depth insight into consumer switching behavior, but also why consumers seem to neglect the opportunities to switch health insurance in more recent years. The first two surveys were completed in cooperation with radio Noorderlicht, the latter in cooperation with its successor, i.e. Labyrint radio. All three programs cover scientific news. And as such, on average, our respondents are more highly educated compared to the average Dutch population. However, as Hurenkamp and Kramer [18] show, highly educated people are better able to deal with rational decision problems. Therefore, when we find that this group encounters difficulties in finding the right information, and making the right decision, this result will be even worse for the entire Dutch population. We will consider this bias when discussing the results.The first survey aims at creating a deeper understanding of health insurance switching in the Netherlands during the introduction of the HIA in 2006. Respondents were allowed to complete the survey between the 6th and 19th of March 2007 on the radio’s website (http://noorderlicht.vpro.nl). The survey was completed by 478 respondents. Over thirty-five percent was female. The average time to complete the survey was approximately three minutes.The 2005-2006 survey primarily aimed to develop insight into people’s switching behavior. Respondents were asked: “did you recently switch to another health plan?” (Yes/No). After this question we were particularly interested in finding out why consumers switched their health insurance. They were queried about the reasons for doing so (premium, group purchasing plans etc.). Moreover, information about socio-demographic variables was included in the questionnaire, including age, gender, and education level. Along the lines of previous studies (e.g. [19]) we included the following variables in our survey: premium per month, membership of a purchasing plan, expectations about improved service, and dissatisfaction with the previous health insurance company. The variables were measured on a 5-point scale from 1 (hardly) to 5 (very much) in order to create a hierarchy among these determinants.The 2009 survey was completed by 389 respondents. This survey focuses on health plan switching in November 2008-January 2009. The primary aim of this survey was to find out why relatively few consumers actually switch their insurance plan. This question gained importance as the percentage of consumers switching health plans dramatically decreases from 20 percent in 2006 to four percent in 2009 [3]. Additionally, this latter questionnaire distinguishes between non-switchers not having considered changing their health care insurance and nonswitchers that did re-evaluate their opportunities, but in the end deliberately decided not to switch their insurance plans [7]. Respondents were allowed to fill in this survey in April 2009. The final survey (n = 190) was available in February 2011 for respondents to fill in. This was a relatively small survey, used to gain some extra insight into non-switching behavior, for instance related to the expectation of not being accepted [2] and the opportunity to find the right insurance. All surveys were designed to include respondents with a health insurance. These are Dutch people aged 18 years and older as children have free insurance with their parents. A paired samples t-test was used to uncover differences between groups. In addition, Anova testing was used.
