money can refer to the very liquid assets included in the technical definition, but it usually refers to something much broader. When someone says "She has a lot of money," the intended meaning is almost certainly that she has a lot of what economists would call financial wealth, which includes not only the most liquid assets (which tend to pay low or zero returns), but also stocks, bonds and other financial investments not included in the technical definition. Non-financial assets, such as land and buildings, may also be included. For example, dictionary definitions of money include "wealth reckoned in terms of money" and "persons or interests possessing or controlling great wealth", neither of which correspond to the economic definition. A related but different everyday usage occurs in the sentence "He makes a lot of money." This refers to a variable that economists call income. Unlike the usages mentioned above, this one has the units "dollars, or another currency, per unit of time", where the unit of time might be a week, month, or year, making it a flow variable. "Investment" and "capital" While financial economists use the word investment to refer to the acquisition and holding of potentially income-generating forms of wealth such as stocks and bonds, macroeconomists usually use the word for the sum of fixed investment—the purchasing of a certain amount of newly produced productive equipment, buildings or other productive physical assets per unit of time—and inventory investment—the accumulation of inventories over time. This is one of the major types of expenditure in an economy, the others being consumption expenditure, government expenditure, and expenditure on a country's export goods by people outside the country. The everyday usage of investment coincides with the one used by financial economists—the acquisition and holding of potentially income-generating forms of wealth such as stocks and bonds. Similarly, while financial economists use the word capital to refer to funds used by entrepreneurs and businesses to buy what they need to make their products or to provide their services, macroeconomists and microeconomists use the term capital to mean productive equipment, buildings or other productive physical assets. As with the term investment, the everyday usage of capital coincides with its use by financial economists. "Government spending" Economists distinguish between government spending on newly produced goods and services, such as paying a company to build a new highway, and government spending on transfer payments, which are payments
