Capital income includes payments to owners for which type of ownership?

Capital income refers to the returns earned on ownership of capital assets. This includes a variety of payments made to owners in exchange for their investment in assets that generate income. Tangible capital is comprised of physical assets such as buildings and machinery, while intangible capital includes non-physical assets like patents and copyrights. Both types of capital can yield income for their owners through various means, thereby making capital income a function of ownership of these assets.

In the context of the options, tangible and intangible capital are directly associated with capital income as they involve ownership of productive assets that provide returns like dividends, interest, or profits. Such payments are a reward for the risk taken and the value of these owned assets in the economy.

Wages and salaries, on the other hand, pertain to compensation for labor, which belong to a different category of income. Rent and lease payments may represent payments for the use of someone else's capital rather than income derived from ownership of capital itself. Lastly, sales and taxes are not directly payments to owners for their ownership of capital—they relate more to transactions and obligations to government entities, respectively. Therefore, the first choice is the only one that accurately describes payments made to owners of capital assets.
