When do price ceilings matter?
3 situation:
1. Binding Price ceiling is effective (surplus)
2. Non-bind Price ceiling is ineffective (shortage)
3. Price ceiling in the long-run (shortage expands)
Describe the two types of externality
1.
Name four types of goods and gives characteristic of each
1. private good (excludable & rivalry) e.g Movie theater
2 club good (excludable & non-rivalry)e.g Cable tv
3. Common resource good (non-excludable & rivalry) e.g fish in the lake, tragedy of the common

Two types of costs and explain
Explicit costs: Tangible, out-of-pocket expenses.
E.g rent, utility, wage,
Implicit costs : hidden cost (opportunity cost of time, money, capital)
How do you calculate profit?
2 ways:
Profit = (Price -ATC) * Q
Profit = TR - TC
What will be the effect of a nonbinding price ceiling?
No effect, because price ceiling is above market price.
Which of the following activities would most likely create a negative

Difference between accounting profit and economic profit
Accounting profit = revenues – explicit costs
Economic profit = revenues – (explicit + implicit costs).
What is the formular of the following?
TC =
AVC =
AFC =
ATC =
TC = TFC + TVC
AVC = VC / Q
AFC = FC / Q
ATC = TC / Q
When do price floors matter?
Three different situations:
1. Binding Price floor is effective (surplus)
2. Non-binding Price floor
3. Long-run effects of price floor (surplus expands)
Which of the following activities is most likely to create a positive externality?
A. eating a slice of pizza
B. smoking a cigarette
C. taking a nap
D. getting a college degree
D. getting a college degree

A. Subsidize the production of good X.
B. Tax the production of good X.
C. Limit how much of good X can be produced.
D. Require the producers of good X to pay for external costs that arise.
A. Subsidize the production of good X.
In long run, Fixed cost is.......
variable, can change, adjust.
