Study Notes
Firm Profit and Production Decisions
- At a price of 12,thefirm′sprofitis12, the firm's profit is 12,thefirm′sprofitis84.
- At a price of $4, the firm should stay open and earn short-run losses, as it covers variable costs and some fixed costs.
- The firm will shut down at a price below or equal to $4.
Price Floors and Ceilings
- Price floors lead to inefficiencies such as wasted resources, inefficiently high quality, and black markets.
- Price ceilings lead to shortages and inefficient allocation of resources. One example of an effective price ceiling would be at point 'b', resulting in a shortage between points 'f' and 'e'.
- Price ceilings can result in black market transactions.
Market Equilibrium and Surplus
- Equilibrium price is $18, and equilibrium quantity is 180.
- Consumer surplus is the area above the demand curve and below the market price.
- Producer surplus is the area below the market price and above the supply curve.
Cost Curves and Production
- Total cost (TC) equals fixed cost (FC) plus variable cost (VC).
- Average fixed cost decreases as output increases.
- Marginal cost (MC) is the change in total cost divided by the change in quantity of output. It increases due to diminishing returns to labor.
Short Run and Long Run
- In the short run, at least one input is fixed.
- In the long run, all inputs can be varied.
- Marginal product of an input is the additional quantity of output produced by using one more unit of input.
Externalities
- Negative externalities, such as pollution from plastic bags, result in a difference between marginal private benefit (MPB) and marginal social benefit (MSB).
- A tax per unit can internalize the externality, shifting the supply curve from S to S'. The optimal quantity with the tax is Qopt.
