Shifts to the right
If the demand curve reflects consumers' full willingness to pay, and the supply curve reflects all costs of production, then which of the following is true?
The benefit surpluses shared between consumers and producers will be maximized.
In crude oil production, the increasing marginal cost explains:
Why the supply curve is upward sloping
Refer to the diagram. Assuming equilibrium price P1, consumer surplus is represented by areas:
a + b
Refer to the diagram above. If actual production and consumption occur at Q1:
an efficiency loss (or deadweight loss) of b + d occurs.
Refer to the diagram in which S is the market supply curve and S1 is a supply curve comprising all costs of production, including external costs. Assume that the number of people affected by these external costs is large. Without government interference, this market will reach:
an overallocation of resources to this product.
People enjoy outdoor holiday lighting displays and would be willing to pay to see these displays but can't be made to pay. Because those who put up lights are unable to charge others to view them, they don't put up as many lights as people would like. This is an example of a:
demand-side market failure.
A government-mandated increase in the price of smart phones will:
increase the quantity supplied of smart phones and decrease the quantity demanded of them.

price ceiling and a shortage of 100 shirts.
The graph above is a market for shirts. At a price of $20, this market will experience a:
price floor and a surplus of 100 shirts.
In a hot area of Arizona where they generate a lot of their electricity with wind turbines, the demand for electricity falls on windy days as people switch off their air conditioners and enjoy the breeze. But at the same time, the amount of electricity supplied increases as the wind turbines spin faster. We can expect that, on a windy day in this electricity market, the equilibrium:
price must fall and equilibrium quantity may rise, fall, or remain unchanged.
If the supply of a product increases and the demand for that product simultaneously decreases, then equilibrium:
price must fall, but equilibrium quantity may rise, fall, or remain unchanged.

Refer to the diagrams for two separate product markets. Assume that society's optimal level of output in each market is Q0 and that government purposely shifts the market supply curve from S to S1 in diagram (a) on the left and from S to S2 in diagram (b) on the right. The shift of the supply curve from S to S2 in diagram (b) might be caused by a per-unit:
subsidy paid to the producers of this product.
Other things equal, if the price of electronic circuit board, a key resource used to produce digital cameras, falls, the:
supply curve of digital camera will shift to the right.

Refer to the diagrams for two separate product markets. Assume that society's optimal level of output in each market is Q0 and that government purposely shifts the market supply curve from S to S1 in diagram (a) on the left and from S to S2 in diagram (b) on the right.

tax on the producers of this product.
