The comparison of GDP per capita elasticities across a allows for assessing the distributional effects of GDP per capita growth. Severe under-representation of top-income household in surveys could account in part the low elasticity even at the level of average household, if this group has benefited from a growing share of total income, as has been documented in several countries (Atkinson et al., In fact, it is now consensually established that household surveys tend to be representative of the 99% of the income distribution but fail to capture the top 1%. In addition, such underreporting pattern has been growing over time (Burkhauser et al., It is assumed that GDP per capita drives long-run levels of household incomes across the distribution.
