Scope

What is the monetary value of a statistical life year derived from studies on societal willingness to pay (WTP) for mortality risk reductions?

Definition

Data

ExternE 2005 [1]

Results are based on a contingent valuation study (NewExt) on changes in life-expectancy conducted simultaneously in France, UK, and Italy. The objective of the study was to derive monetary unit value for the incidence of premature death resulting from air pollution in Europe. The survey protocol included people over the age of 40, with 1/3 of these above the age of 60.

  • Chronic exposure mortality impacts (death after 10 years of exposure, 3% discount rate applied)
    • Upper bound: €151 110
    • Mean: €125 250
    • Median: €55 800 (rounded to €50 000, recommended central estimate)
    • Lower bound: €18 250
  • Acute exposure mortality impacts (immediate death, assumed that the victim's health condition is not a factor in WTP, no discount applied)
    • Upper bound: €225 000
    • Median: €75 000
    • Lower bound: €27 240
  • A Weibull distribution is assumed because it had the best fit to the data
  • Upper and lower bounds are considerably less robust than the central estimates


Values used in CAFE CBA 2005 [2]

Values are based on the NewExt study, price year 2000

  • Chronic exposure mortality impacts
    • Median: €52 000
    • Mean: €120 000


NEEDS 2006 [3]

Recommended mean VOLY estimates for Europe:

  • EU15 + Switzerland €41 000
  • New member countries €33 000
  • EU25 €40 000


Desaigues et al. 2011[4]:

  • Contingent valuation study on the monetary value of a life year in EU in the air pollution context.
  • The result is based on a survay conducted in 9 European countries: France, Spain, UK, Denmark, Germany, Switzerland, Czech Republic, Hungary, and Poland.
  • Recommended VOLY estimate for cost-benefit analysis of air pollution policies for the European Union is 40 000 €.
  • Suggested confidence interval: lower limit 25 000 €, upper limit 100 000 €.


Dependencies

VOLY is expected to vary from country to country due to income levels and cultural valuations.

Unit

euro/one statistical life year

Formula

A rough compilation is done of the above-mentioned ranges.

Stepwise uniform: (cumulative probabilities 0, 0.05, 0.25, 0.5, 0.75, 0.95, 1)(18250, 27240, 41000, 52000, 75000, 125250, 151110)
