OECD Conference on wealth inequalities: measurement and policies
Paris, 26 April 2018
2. Motivation
• OECD guidelines for Micro Statistics on Household
Wealth (2013)
• The Household Finance and Consumption Network
(2006-
• Luxembourg Wealth Study (2003-
• Wealth inequality becomes a major concern for policy-
making
• So, we need to evaluate the sources of wealth
inequality as well as the effectives of policies
• We need to understand the distributional impact of
wealth components
• Concerns about wealth distribution should not only be
about the top part of this distribution
3. Questions
• Do we have all subcomponents of wealth
to understand the wealth distribution? If
not, what is missing?
• Do we still need to enlarge the range of
assets and liabilities?
• How much inequality indicators change if
we broaden the wealth components?
• Does broadening the range of assets
matter for the policy-making process?
4. Luxembourg Income Study (LIS)
Mission
To enable, facilitate, promote, and conduct cross-national
comparative research on socio-economic outcomes and on the
institutional factors that shape those outcomes.

18. Conclusions
• We need to have detailed components of
financial and non-financial assets,
specifically pension assets
• We can be misinformed if we have only
aggregated measures of assets
• All this is necessary for informed
governmental policies.
19. Thank you for your attention
Any questions are welcome !
“When you can measure what you are speaking about and express
it in numbers you know something about it. But when you cannot
measure it or express it in numbers, you knowledge is of a meager
and unsatisfactory kind.”
Sir William Thomson
British Mathematician and physician (Belfast, 1824 - Netherhall, 1907)
