Is there any chance that the causal flow is that buying health insurance or life insurance makes you die earlier? So yeah so this is one of the central empirical challenges to researchers in this area. The problem we've been talking about is one of selection that people who are higher risk are more likely to buy the insurance in the first place. There's a huge body of evidence some of which I've contributed to documenting precisely this phenomenon.
If you knew exactly when every person was going to die, or require medical care, you could make a killing buying and selling insurance. Nobody knows these things, of course -- the future is hard to predict -- but some people know something about the future that other people don't. This sets up adverse selection: the ability of one party to leverage information another party doesn't have, in order to gain an economic advantage. Economist Amy Finkelstein is an expert in this phenomenon, as well as the usefulness of empirical studies in economic research.
