Q

Market

A

A market is a group of buyers and sellers of a particular good or service. The buyers as a group determine the demand for the product, and the sellers as a group determine the supply of the product.

Q

which way does the demand graph slope? Why?

A

Downwards, because other things being equal, lower P= greater Q demanded

Q

What are some variables that SHIFT the demand curve?

A

1) Income
a. Lower income= less money you have to spend in total→ therefore less to spend on goods
2) Price of related goods
a. Substitutes
i. Fall in price of one good reduces demand for another good
ii. E.g. almond milk and cow’s milk
b. Complements
i. Fall in price of one good raises demand for another good
ii. E.g. cereal and milk
3) Tastes
4) Expectations
a. Expectations about the future may affect demand for a good or service today
b. E.g. if you expect to earn a higher income next month→ you may choose to save now and spent more later
5) Number of buyers
a. The greater the number of buyers, the Q demanded in the market would be HIGHER at every price and market demand would INCREASE

Q

Substitutes

A

Two goods for which an increase in the price of one leads to an increase in the demand for the other

22
Q

Complements

A

Two goods for which an increase in the price of one leads to a decrease in the demand for the other

23
Q

Surplus

A

A situation in which quantity supplied is greater than quantity demanded

24
Q

Shortage

A

A situation in which quantity demanded is greater than quantity supplied

25
Q

Budget constraints

A

The limit on the consumption bundles that a consumer can afford

26
Q

Marginal rate of substitution

A

The rate at which a consumer is willing to trade one good for another.
The marginal rate of substitution between two goods depends on their marginal utilities.

27
Q

Indifference curve

A

A curve that shows consumption bundles that give the consumer the same level of satisfaction

28
Q

Total revenue

A

The amount a firm receives for the sale of its output

29
Q

Total cost

A

The market value of the inputs a firm uses in production

30
Q

Profit

A

Total revenue minus total cost

31
Q

Explicit costs

A

Input costs that require an outlay of money by the firm

32
Q

Implicit costs

A

Input costs that do not require an outlay of money by the firm

33
Q

Fixed costs

A

Costs that do not vary with the quantity of output produced

34
Q

Variable costs

A

Costs that vary with the quantity of output produced

35
Q

Average total costs

A

Total cost divided by the quantity of output

36
Q

Average fixed costs

A

Fixed cost divided by the quantity of output

37
Q

Average variable costs

A

Variable cost divided by the quantity of output

38
Q

Marginal cost

A

The increase in total cost that arises from an extra unit of production

39
Q

Diminishing marginal utility

A

The more of the good the consumer already has, the lower the marginal utility provided by an extra unit of that good.

40
Q

Marginal utility

A

The extra utility gained from consuming one more unit of a good, holding others constant. Utility is a measure of the satisfaction from consuming goods.

41
Q

Marginal rate of transformation

A

The slope of the production possibilities curve, and the rate at which society can transform one good into another.

42
Q

Marginal Rate of Technical Substitution

A

The amount of one factor of production given up per unit increase in another factor of production, while maintaining the same level of output.

43
Q

Production function

A

The relationship between the maximum output that can be produced corresponding to any combination of factor inputs.

44
Q

Price elasticity of demand

A

The percentage change in quantity demanded resulting from a 1 percent change in price.

45
Q

Price elasticity of supply

A

The percentage change in quantity supplied resulting from a 1 percent change in price.

46
Q

A

A market structure with (1) numerous buyers and sellers, (2) perfect information, (3) free entry and exit, and (4) a homogeneous product

47
Q

Deadweight loss

A

A measure of the net loss of society’s welfare resulting from a misallocation of resources, usually situations in which the marginal benefits of a good do not equal marginal costs

48
Q

Public good

A

A good (e.g., national defense) that no one can be prevented from consuming, (i.e., nonexcludable) and that can be consumed by one person without depleting it for another (i.e., nonrival). The marginal cost of providing the good to another consumer is zero

49
Q

Monopoly

A

Situations in which a firm faces a negatively sloped demand curve. In a pure monopoly, no other firm produces a close substitute for the firm’s product. The demand curve facing the monopolist is the market demand curve.

50
Q

Monopsony

A

Situations in which a firm faces a positively sloped supply curve in the product or factor market because it is the only buyer. The supply curve facing the monopsonist is the market supply curve.

51
Q

Technical efficiency

A

occurs when the firm produces the maximum possible sustained output from a given set of inputs

52
Q

Allocative efficiency

A

situations in which either inputs or outputs are put to their best possible uses in the economy so that no further gains in output or welfare are possible
