9. Economic Cost of Resources
Opportunity cost of using any resource is:
What firm owners must give up to use the resource
Market-supplied resources
Owned by others & hired, rented, or leased
Owner-supplied resources
Owned & used by the firm

10. Opportunity costs
Definition: Opportunity cost is whatever is given up (forsaken) to get an item or service or anything else you want to do or enjoy
If you are have to take time off work to go to the dentist, what is the opportunity cost of a $100 visit.

11. Total Economic Cost Total Economic Cost Explicit Costs Implicit Costs
Sum of opportunity costs of both market-supplied resources & owner-supplied resources
Explicit Costs
Monetary payments to owners of market-supplied resources
Implicit Costs
Nonmonetary opportunity costs of using owner-supplied resources

12. Economic Cost of Using Resources (Figure 1.1)+ =

13. Types of Implicit Costs
Opportunity cost of cash provided by owners
Equity capital
Opportunity cost of using land or capital owned by the firm
Opportunity cost of owner’s time spent managing or working for the firm

14. Economic Profit versus Accounting Profit
Economic profit = Total revenue – Total economic cost
= Total revenue – Explicit costs – Implicit costs
Accounting profit = Total revenue – Explicit costs
Accounting profit does not subtract implicit costs from total revenue
Firm owners must cover all costs of all resources used by the firm
Objective is to maximize economic profit

15. Maximizing the Value of a Firm
Price for which it can be sold
Equal to net present value of expected future profit
Risk premium
Accounts for risk of not knowing future profits
The larger the risk, the higher the risk premium, & the lower the firm’s value

16. Maximizing the Value of a Firm
Maximize firm’s value by maximizing profit in each time period
Cost & revenue conditions must be independent across time periods
Cannot be reliant on previous periods production
Value of a firm =

17. Separation of Ownership & Control
Principal-agent problem
Conflict that arises when goals of management (agent) do not match goals of owner (principal)
Moral Hazard
When either party to an agreement has incentive not to abide by all its provisions & one party cannot cost effectively monitor the agreement

18. Corporate Control Mechanisms
Require managers to hold stipulated amount of firm’s equity
Increase percentage of outsiders serving on board of directors
Finance corporate investments with debt instead of equity

19. Price-Takers vs. Price-Setters
Price-taking firm
Cannot set price of its product
Price is determined strictly by market forces of demand & supply
Price-setting firm
Can set price of its product
Has a degree of market power, which is ability to raise price without losing all sales

20. What is a Market?
A market is any arrangement through which buyers & sellers exchange goods & services
Markets reduce transaction costs
Costs of making a transaction other than the price of the good or service

21. Markets and Economic Activity
Markets are where trade takes place between a buyer an seller. These days it doesn’t have to be a physical place
Market economies let the ‘invisible hand’ or market forces allocate its resources.
This is said to produce the highest level of efficiency
Producers and consumers interact in a market to establish the price of goods or services and quantity produced.
Any impediments are said by most economists to reduce efficiency and total welfare

22. Market Structures
Market characteristics that determine the economic environment in which a firm operates
Number & size of firms in market
Degree of product differentiation
Likelihood of new firms entering market

23. Perfect Competition Large number of relatively small firms
Undifferentiated product
No barriers to entry

24. Monopoly Single firm Produces product with no close substitutes
Protected by a barrier to entry

25. Monopolistic Competition
Large number of relatively small firms
Differentiated products
No barriers to entry

26. Oligopoly Few firms produce all or most of market output
Profits are interdependent
Actions by any one firm will affect sales & profits of the other firms

27. Globalization of Markets
Economic integration of markets located in nations around the world
Provides opportunity to sell more goods & services to foreign buyers
Presents threat of increased competition from foreign producers
