LAW OF DIMINISHING MARGINAL RETURNS: A principle stating that as more and more of a variable input is combined with a fixed input in short-run production, the marginal product of the variable input eventually declines. This is THE economic principle underlying the analysis of short-run production for a firm. Among a host of other things, it offers an explanation for the upward-sloping market supply curve. How does the law of diminishing marginal returns help us understand supply? The law of supply and the upward-sloping supply curve indicate that a firm needs to receive higher prices to produce and sell larger quantities. Why do they need higher prices?

The third GDP highlight phrase is 'a given period of time'. GDP is production that takes place during a specific period, usually one year. - GDP is a flow. Current production takes place during the specific period of time under study.
- Flows are measured over a period of time. GDP is measured from January 1st to December 31st.
- Stocks are measured at a point in time. The quantity of money is measured at an instant in time, like July 26th at 8:15.
- In addition to GDP, other production and income measures in this lesson are flows.
- In addition to money, employment, business inventories, and labor force are stocks.

MARGINAL UTILITY AND DEMAND An explanation of the law of demand and the negatively-sloped demand curve based on utility analysis and the law of diminishing marginal utility. The law of diminishing marginal utility states that marginal utility declines as consumption increases. Because demand price depends on the marginal utility obtained from a good, price also declines as consumption increases, meaning price and quantity demanded are inversely related, which is the law of demand.

[What's This?]
Today, you are likely to spend a great deal of time at a crowded estate auction hoping to buy either a coffee cup commemorating last Friday (you know why) or a wall poster commemorating the first day of spring. Be on the lookout for small children selling products door-to-door.
