We study the formation of biased expectations across domains and examine whether they have a unique influence on health and financial behaviors. Combining individual-level longitudinal, retrospective, and end of life data from several European countries for more than a decade, we estimate the time-varying individual level bias in ‘survival expectations' (BSE) and compare it to a similar type of bias in the formation of ‘meteorological expectations' (BME). We exploit the variation across individual's family history (parental age at death) to evaluate the causal effect of BSE on health and financial behaviors, and we compare it to the effect of BME. This allows to investigate whether the BSE effect is due to private information, or another mechanism. We find that BSE increases the likelihood of engaging in less risky health and financial behaviors. We estimate that a one standard deviation increase in BSE reduces the average individual probability of smoking by 48% (and increase the probability of holding retirement accounts by 69%). In contrast, BME has little effect on healthy behaviors, and is only associated with a change in some financial behaviors.

Individual preferences for ‘ageing in place’ (AIP) in old age are not well understood. One way to test the strength of AIP preference is to investigate the effect of health shocks on residential mobility to smaller size or value dwellings, which we refer to as 'housing downsizing'. This paper exploits more than a decade worth of longitudinal data to study older people's housing decisions across a wide range of European countries. We estimate the effect of health shocks on different proxies for housing downsizing (residential mobility, differences in home value, home value to wealth ratio), to examine the persistence of AIP preferences. Our findings suggest that consistently with the AIP hypothesis, after every decade of life, the likelihood of downsizing decreases by two percentage points (pp). However, the experience of a health shock partially reverts such culturally embedded preference for AIP by a non-negligible magnitude We estimate a 9pp increase in the probability of residential mobility after the onset of a degenerative illness), a 0.6 a fewer rooms after the onset of a degenerative illness. Such estimates are larger in northern and central European countries.
