This paper investigates empirically how different insurance plans affect individual behaviours in terms of prevention activities in the U.K. The data come from the British Household Panel Survey. We test if purchasing private health insurance modifies the probability of exercising, undergoing regular check-ups and smoking. Based on both simple probits and an IV strategy, our results suggest that, in the U.K., contracting private health insurance does not lead to less prevention.

While many theoretical arguments have been proposed to explain the decision whether to purchase long-term care (LTC) insurance, little work has been done to study this phenomenon empirically. This article uses cross-sectional data from the newly developed SHARE (Survey of Health, Ageing, and Retirement in Europe) database to estimate the determinants of the probability of purchasing LTC insurance in France. We show that LTC insurance is purchased not only to preserve bequests and to financially protect families in the event of disability, but also to reduce the burden on potential informal care givers. Risk behaviours as well as experience of disability also play a significant role in explaining the demand for LTC insurance in France.

This chapter surveys the economic literature on prevention and precaution. Prevention refers as either a self-protection activity -i.e. a reduction in the probability of a loss -or a self-insurance activityi.e. a reduction of the loss -. Precaution is defined as a prudent and temporary activity when the risk is imperfectly known. We first present results on prevention, including the effect of risk preferences, wealth and background risks. Second, we discuss how the concept of precaution is strongly linked to the effect of arrival of information over time in sequential models as well as to situations in which there is ambiguity over probability distributions.
