# Efficiency cost

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

The inverse market demand curve is P=140-Q, and the inverse supply curve is P=20+Q. Now suppose a commodity subsidy of \$20 is given for each unit of production. In this new distorted market equilibrium, compute the following:

1. equilibrium demand price
2. equilibrium supply price
3. equilibrium quantity
4. the additional value of consumption, relative to the undistorted equilibrium (i.e.)
(the equilibrium without the commodity subsidy).
5. the additional resource cost, relative to the undistorted equilibrium (i.e) without subsidy
6. the increased consumer surplus relative to the undistorted equilibrium (i.e) without
subsidy.
7. the increased producer surplus relative to the undistorted equilibrium (i.e) without
susbidy.
8. The subsidy payment in dollars.
9. The efficiency cost of the subsidy relative to the undistorted equilibrium (ie) without
subsidy.

The inverse market demand curve is P=140-Q, and the inverse supply curve is P=20+Q. Now suppose a commodity subsidy of \$20 is imposed on each unit of production in this market. In the new distorted market equilibrium, compute the following:

1. equilibrium demand price

2. equilibrium supply price
