By regressing life satisfaction scores on income and other determinants of life satisfaction, one obtains a measure of the subjective price of the non-income components by dividing the coefficient of the latter variable by the income’s coefficient. The obtained shadow price is the amount of money that would fully compensate, in terms of life satisfaction, for the loss or gain of one unit of that component. This technique is increasingly used in cost-benefit analysis (see e.g. the UK Green Book15).
