If there were a market for human lives -- even a black market -- that would convince me that people value their lives at something less than infinity. But there isn't.
Yes there is, although I will grant you that there is no one market where the tradeoff happens explicitly. That being said, there
are differentials between different sectors of the labor- and product markets through which people trade off lives for money implicitly. For a semi-fictional but instructive example, you can look at the wage difference between lion tamers and rabbit tamers, compare it with the risk difference between getting eaten by a lion and getting eaten by a rabbit, and deduce an implied value of a human life by dividing one into the other.
In
real statistical research, the idea is similar, but the execution is more complicated because jobs differ in more ways than just their risk to workers' lives. But you can still work out a price per life by running a multiple-regression analysis and looking at the coefficient of the deadly-risk variable for determining differences in market wages. I will stop here because actually
running such a regression is tedious and lies outside the scope of Debra's thread. I'll just leave you with a link to
this peer-reviewed paper (PDF), which
has run such an analysis and finds that in America, the value of a human life lies somewhere between $4 million and $9 million. This is consistent with the $5 million I came up with earler.

No, you're measuring people's willingness to
take risk in exchange for offsetting benefits. For example, if we offer someone a game of Russian roulette with one bullet in a ten-chamber revolver, and he is willing to take it for a reward of a million dollars but not of one hundred thousand, we can interpret his behavior as him valuing his own life at more than a million but less than ten million dollars. How is this interpretation unsound?
joefromchicago wrote:And people are extraordinarily bad at evaluating risk.
Maybe so, but the question was whether people place an infinite or a finite value on their own lives. So let me ask you: Do people know that overeating, smoking, base-jumping and so forth pose
any risk to their lives at all? Are they taking at least
some of these risks willingly nevertheless? As long as we can stipulate that the answer to both these questions is "yes", that's enough to decide that the value people place on their own lives is finite rather than infinite. The incompetence you attribute to people might lead them to choose the wrong finite value over the right finite value, but not a finite value over an infinite one.

Not so. Society's valuation is the sum of all individuals' valuations
except for the individual whose life is being valued.
This sounds absurd to me. Can you give me a link to utilitarians who actually said that?

I already mentioned the labor market. Similar effects can be derived from product markets. You ask, "at what discount do risky products have to sell until consumers become indifferent between buying them and buying safer products?" Then you run your multiple regression (see above), and derive the implied value of life from the risk coefficient.
