Abstract: | Youth is one of the phases in the life-cycle when some of the most decisive life transitions take place. Entering the labour market or leaving parental home are events with important consequences for the economic well-being of young adults. In this paper, the interrelationship between employment, residential emancipation and poverty dynamics is studied for eight European countries by means of an econometric model with feedback effects. Results show that youth poverty genuine state dependence is positive and highly significant. Evidence proves there is a strong causal effect between poverty and leaving home in Scandinavian countries, however, time in economic hardship does not last long. In Southern Europe, instead, youth tend to leave their parental home much later in order to avoid falling into a poverty state that is more persistent. Past poverty has negative consequences on the likelihood of employment. |

Abstract: | Background How to communicate uncertainty is a major concern in medicine and in health economics. We aimed at studying the framing effects of risk communication on stated preferences in a discrete choice experiment (DCE) performed to elicit women’s preferences for Hormone Replacement Therapy. Methods Two versions of the questionnaire were randomly administered to respondents. Multiple risks were expressed as natural frequencies using either a constant reference class (Design 1) or variable reference classes (Design 2). We first tested whether Design 1 would impose a lower cognitive burden than Design 2. We then examined whether the two designs resulted in different utility model estimates. Results Design 1 improved consistency (monotonicity and stability). However, rates of dominance or intransitive responses did not differ across designs. Design 1 decreased women’s sensitivity to the risk of fractures and increased their sensitivity to the risk of breast cancer as compared to all other attributes. Discussion Framing effects of risk communication on stated preferences may be a major problem in the design of DCEs. More research is needed to determine whether our findings are replicable and to further investigate the normative question of how to improve risk communication in health-related decision-making. |
