Household resources consist mainly of the wages earned, income from property (interest, dividends, income from land, etc.), of earnings from market production and social benefits. The balance of the operating account of households owning sole proprietorships is called "mixed income" because it corresponds indistinctly to the remuneration for the work of the individual entrepreneur and to the remuneration of his productive capital.
Similarly, when households are producers of goods and services for their own end use (excluding housing services) they have a "mixed income" in compensation of their work and tied-up capital. Furthermore, the balance of the operating account of households producing housing services is the gross operating margin which corresponds solely to the remuneration of real estate capital.
