In each of the six very different surveys, using a number of assumptions, we are able to estimate the elasticity of marginal utility with respect to income. We thank the Esmee Fairbairn Foundation for financial support to the CEP well-being programme. In normative public economics it is crucial to know how fast the marginal utility of income declines as income increases. Therefore, if the top 1% gain more wealth/income, the effect is simply to push up the prices of these ‘exclusive goods’ By definition the best 1% of art, houses are limited. A natural way to do this is to weight each person's change in income by his or her marginal utility of income. Their utility as a function of income is given as follows Larry: U L (I) = 10.
