Abstract

This article assesses the reliability of wealth surveys to compile Distributional National Accounts, which link micro data to the National Accounts. Aggregates implied by the Household Finance and Consumption Survey (HFCS) usually yield much lower amounts than macroeconomic statistics. An important source of this gap may be the lack of the wealthiest households in the HFCS. This article combines a semi-parametric Pareto model estimated from top survey data and observations from rich lists with a stratification approach to quantify the impact of the missing wealthy households on component-specific micro-macro gaps. We find that unadjusted micro data substantially underestimates wealth inequality. Largest effects are found for equity. For other components, the missing wealthy explain less than ten percentage points of the micro-macro gap. We document that differences in oversampling strategies limits the cross-country comparability of unadjusted survey-implied wealth distributions and that our top tail adjustment leads to internationally more comparable measures.
