Q

Law of Diminishing Marginal Utility

A

As consumption of a good increases, marginal utility, or the extra utility the consumer receives, decreases which each additional unit consumed, therefore consumers will buy more only if the price falls; this underlies the law of demand.

Q

Substitution Effect

A

Part of an explanation of the law of demand; there is an inverse relationship between price and quantity demanded because as price falls consumers substitute the now less expensive good for other products.

A time period in which all inputs can be changed.

32
Q

Total Product

A

The total quantity of output produced by a firm

33
Q

Marginal Product

A

The extra or additional output that results from one additional unit of a variable input.

34
Q

Law of Diminishing Marginal Returns

A

A law stating that as more and more units of a variable input are added to one or more fixed products, the marginal product of the variable input at first increases, but there comes a point when the marginal product of the variable input begins to decrease.

35
Q

Total cost

A

The total costs incurred by a firm that undertakes production of something

36
Q

Marginal Cost

A

The extra or additional cost of producing one more unit of output.

37
Q

Excess Supply

A

In the context of demand and supply, occurs when the quantity of a good demanded is smaller than the quantity supplied, leading to a surplus.

38
Q

Surplus

A

The extra supply that results when the quantity supplied is greater than quantity demanded.

39
Q

Excess Demand

A

In the context of demand and supply, occurs when the quantity of a good demanded is greater than the quantity supplied, leading to a shortage of the good.

40
Q

Shortage

A

The amount by which quantity demanded is greater than quantity supplied.

41
Q

Equilibrium

A

A state of balance such that there is no tendency to change.

42
Q

Market Equilibrium

A

Occurs where quantity demanded is equal to quantity supplied and there is no tendency for the price or quantity to change.

43
Q

Equilibrium Price

A

The price determined in a market when quantity demanded is equal to quantity supplied, and there is no tendency for the price to change.

44
Q

Equilibrium Quantity

A

The quantity that is bought and sold when a market is in equilibrium, when quantity demanded is equal to quantity supplied.

45
Q

Competitive Market Equilibrium

A

The extra benefit producers get by receiving a higher price for the good they are selling than the price they are willing to receive.

48
Q
