Q

Decreasing Cost Industry

A

Experiences decreasing average production costs as industry output increases

24
Q

Productive Efficiency

A

Occurs when a firm produces at the lowest unit cost where MC = AC

25
Q

Economies of Scope

A

Exist when a firm’s average production costs decrease because multiple products are being produced

26
Q

Perfect/Pure Competition Characteristics

A
  • Many Sellers
  • Standardized Product

Accept the market price as given and can sell all that they want at that price

28
Q

Economic Profits

A

Total Revenue - Total Cost (Includes Opportunity Costs)

29
Q

Accounting Profits

A

Consist of only the monetary costs of the firm

30
Q

Normal Profits

A

Earning a return equivalent to the opportunity cost of time (Economic Profit is 0)

31
Q

Total Revenue (TR)

A

The amount of money taken in from the sale of a good (TR = P*Q)

32
Q

Marginal Revenue (MR)

TR/Q

34
Q

Profit

A

TR - TC

35

37
Q

Price Discrimination

A

Charging different customers different prices that do not reflect differences in production costs

38
Q

Perfect Price Discrimination

A

Ideal for a firm to charge every customer the most they are willing to pay and turning consumer surplus into profit

Q

Oligopoly

A

An industry with a small number of firms selling a standardized/differentiated products

40
Q

Market Power

A

Specified that monopolistic behavior such as price discrimination, tying contracts, and unlimited mergers are illegal

50
Q

Robinson-Patman Act (1936)
