the product in which it has a comparative advantage.

Let P represent price; let QS represent quantity supplied; and assume the equation of the
supply curve is . If 90 units of the good are produced and sold, then
producer surplus amounts to $1,350.
Producer surplus is the cost of production minus the amount a seller is paid.
Minimum-wage laws affect all workers.
Economists at the Congressional Budget Office estimated that for 2009, the U.S. natural

of labor supplied.
Public policy, without intending to do so, can increase frictional unemployment.
