44. THE COSTS OF PRODUCTION 44
Total Revenue, Total Cost, Profit
• We assume that the firm’s goal is to maximize
profit.
Profit = Total revenue – Total cost
the amount a
firm receives
from the sale
of its output
the market
value of the
inputs a firm
uses in
production
46. Let’s think more specifically about costs
• Fixed Costs = costs that do not change based on
production and don’t change in SR
• Examples: capital goods, tools, buildings, menus
Nokia factory in Finland
Coke factory in Atlanta, Georgia
47. Special fixed costs
• “Entry costs” – costs to start up the business
Business with low
Entry costs
Business with
very high
Entry costs
48. Costs we can change in the short run
Variable costs = costs that
change based on
production
The more I produce, the
more cost I will incur.
If I don’t produce at all, my
variable costs will be 0
For example: labor,
electricity, raw materials
Nike factory in China
50. Marginal Costs
• Marginal costs = the
cost of producing 1
additional unit
• For example:
• Why helpful?
• Diminishing
marginal product!
