Definition of private wealth

Non-financial assets

  • Dwellings (owner-occupied residence, other real estate)
  • Consumer durables (vehicles, etc.)
  • Valuables
  • Intellectual property

Financial assets

  • Currency and deposits
  • Net equity in own unincorporated business
  • Mututal funds and investment funds
  • (Private) Pensions funds
  • Bonds and other debt securities
  • Shares and other equity
  • Life insurance funds -Other financial assets

Liabilities

  • Owner-occupied residence loans
  • Consumer durable loans (e.g. for vehicles)
  • Other investment loans (collateralized)
  • Other loans (e.g. education loans)

No human, social and cultural capital; No public social security pensions (marketable vs. augmented wealth)

HFCS sampling and underreporting

  • Target population in Austria: 3.9 million households
  • Gross sample in HFCS 2017: 6,280 households
  • Realized interviews: 3,072 households
  • Response rate in HFCS 2017: approx. 50%
  • Residual: refused interviews, invalid addresses, households not available, etc.
  • Response refusal correlates with wealth and is highest at the top (Vermeulen, 2016)
  • Wealthy households own a greater number of assets and miss some components more easily (Kennickell/Woodburn, 1999)

Upstream strategy against underreporting: Oversampling

  • Undercoverage and Underreporting
  • Oversampling is crucial for wealth surveys
  • Oversampling in HFCS 2017: ๐Ÿ‡ง๐Ÿ‡ช ๐Ÿ‡จ๐Ÿ‡พ ๐Ÿ‡ฉ๐Ÿ‡ช ๐Ÿ‡ช๐Ÿ‡ช ๐Ÿ‡ช๐Ÿ‡ธ ๐Ÿ‡ซ๐Ÿ‡ฎ ๐Ÿ‡ซ๐Ÿ‡ท ๐Ÿ‡ฌ๐Ÿ‡ท ๐Ÿ‡ญ๐Ÿ‡ท ๐Ÿ‡ญ๐Ÿ‡บ ๐Ÿ‡ฎ๐Ÿ‡ช ๐Ÿ‡ฑ๐Ÿ‡ป ๐Ÿ‡ฑ๐Ÿ‡น ๐Ÿ‡ฑ๐Ÿ‡บ ๐Ÿ‡ต๐Ÿ‡ฑ ๐Ÿ‡ต๐Ÿ‡น ๐Ÿ‡ธ๐Ÿ‡ฐ
  • No oversampling: ๐Ÿ‡ฆ๐Ÿ‡น ๐Ÿ‡ฎ๐Ÿ‡น ๐Ÿ‡ฒ๐Ÿ‡น ๐Ÿ‡ณ๐Ÿ‡ฑ ๐Ÿ‡ธ๐Ÿ‡ฎ
  • How does oversampling work?
    • External personal wealth data (๐Ÿ‡ซ๐Ÿ‡ท ๐Ÿ‡ช๐Ÿ‡ธ)
    • List of streets with high-income people (๐Ÿ‡ฉ๐Ÿ‡ช ๐Ÿ‡ธ๐Ÿ‡ฐ)
    • Income tax data (๐Ÿ‡ฑ๐Ÿ‡บ 20% of the sample from top 10% earners)
    • Regions with higher average income (๐Ÿ‡ต๐Ÿ‡ฑ)

Downstream strategy against underreporting: Pareto estimation

  • Pareto-Distribution is a sensible approximation to the distribution of large wealth
  • Two parameters:
    • Threshold for โ€œlargeโ€ wealth \(m\)
    • Pareto-Index \(\alpha\)

\[P_i(x_i) = Pr(X_i \leqslant x_i) = 1 - \left(\frac{m_i}{x_i}\right)^{\alpha_i}\] \[\forall ~\text{implicates} ~i = 1...5 \wedge x_i \geqslant m_i\]

A smaller \(\alpha\) means greater inequality. Empirically, \(\alpha\) often is around 1.5 for wealth.
