Private benefi t income (PB) is a catch-all for all sources of income derived from assets and investments, physical and monetary. In a sense, it is rental income, gained from renting out assets such as land, buildings or equipment, or from turning savings into interest-bearing investment. One can make a useful distinction between traditional private benefi t income, notably from land and moneylending, and modern private benefi ts, in which savings are converted into income through fi nancial intermediation, where intermediaries such as banks act as a conduit for turning savings into investment for economic growth.
