The Wealth of Wealthholders

Area of Science:

• Economics
• Survey Methodology
• Financial Research

Background:

• Accurate measurement of wealth is essential for economic modeling and well-being assessments.
• Traditional survey methods face significant challenges in precisely quantifying asset holdings.
• Existing datasets often lack the density and accuracy needed for detailed wealth analysis.

Purpose of the Study:

• To introduce and validate a novel, comprehensive account-by-account approach for eliciting asset information.
• To improve the precision and reduce bias in wealth measurement within survey research.
• To enable sharper inferences on wealth management and the relationship between wealth and economic behavior.

Main Methods:

• Implementation of a new account-by-account elicitation method within the Vanguard Research Initiative (VRI).
• Utilizing a panel of wealthholders, specifically older Americans with substantial financial assets.
• Linking survey responses directly to administrative account balances for validation.

Main Results:

• The account-by-account approach demonstrates the capability to yield precise and unbiased wealth estimates.
• High-quality measurements are achieved for a large sample of wealthholders.
• The linked survey and administrative data provide unprecedented accuracy and density of wealth information.

Conclusions:

• The developed account-by-account method significantly enhances the accuracy of wealth measurement in surveys.
• This approach facilitates more robust analysis of wealth management and economic behaviors.
• The findings offer a superior alternative to existing datasets for wealth-related research.
