2026 Luxembourg Consumption Study (LCS) Workshop

Workshop Summary

On 14 and 15 January 2026, an international expert group convened to discuss key conceptual and empirical challenges in measuring consumption, expenditure, and living standards in a cross-country perspective, in the context of the Luxembourg Consumption Study (LCS). Discussions focused on the strengths and limitations of consumption-based measures relative to income, the treatment of durable goods such as housing and vehicles, and the role of health and education expenditures, including publicly provided services and the differences between high- and low-income countries, with particular attention to making a clear distinction between consumption as a measure of consumption expenditure versus welfare.

Participants emphasized the importance of flexibility and transparency over a single rigid definition, highlighting the need for modular consumption components, clear documentation, and careful handling of cross-country differences related to welfare-state institutions, prices, and survey design. The workshop underscored that consumption measures serve different analytical purposes—particularly for poverty, inequality, and welfare analysis—and that providing well-documented building blocks enables more meaningful and policy-relevant comparisons.

The workshop consisted of two days, the first day was virtual targeted towards collecting relflections and feedback from non-European-based consumption experts while the 2nd day included in-person meeting
