Supply Curve Determination:
Olympia Natural Resources, Inc and Yakima Lumber Ltd., supply cut logs to lumber and paper mills located in the cascades mountain region in the state of Washington. Each company has a different marginal cost of production, depending on its own cost of land owner access, labor and other cutting costs, the distance cut logs must be shipped and so on. The MC of producing 1 unit of output measured as 1,000 board feet of lumber (where 1 board feet is 1 square foot of lumber, 1 inch thick), is
MC(Olympia)=$350+$0.00005Q
MC(Yakima)=$150=$0.0002Q
(A) Assuming these two firms makeup the entire industry in the local area, determine the industry supply curve when P<$350.
(B) Determine the industry supply curve when P>$375
