message: The production function determines all cost functions. The variable cost curve is the inverted short run production function or total product curve. The total cost function is therefore the inverted total product function plus fixed costs. Because the production function determines the variable cost function it necessarily determines the marginal cost curve and the variable cost functions. Jgard5000 (talk) 13:24, 5 November 2009 (UTC)
thread_title: Production Functions and Cost Curves

message: The following two statements in the section "Relationship between short run and long run cost curves" are unclear and may well be incorrect in their intent (although they have a citation):
"8. If the production function has increasing returns to scale, the minimum of the SATC curve will occur at a higher level of production than the long-run cost-minimizing level of production.[8]:292-299 Where LRTC = STC, LRATC = SATC and LRMC = SMC. SMC does not equal LRMC and LRMC does not equal LRAC."
"9. With decreasing returns the minimum of the SATC curve will be tangent to the LRAC curve at a level of production lower than the long run cost-minimizing level of production.[8]:292-299 Where LRTC = STC, LRATC = SATC and LRMC = SMC. SMC does not equal LRMC and LRMC does not equal LRAC."
Actually, with increasing (decreasing) returns to scale, there is no "long-run cost-minimizing level of production," because the long-run average cost curve is monotonically decreasing (increasing).

replies: text: Maybe what you just said here should go in the article.  But the first sentences in 8 and 9 seem wrong as they currently are, because e.g. 8 says that in the downward sloping region of LRAC, i.e. if the firm is operating to the left of the min point of LRAC, then the min of SATC is to the right of the min of LRAC.

message: 1)under what conditions in the short run can a firm earn economic profits?
2)when is economic profit possible in the long run?
3)explain how conmic pofits differ from economic rent  —Preceding unsigned comment added by 41.72.221.50 (talk) 15:34, 26 July 2010 (UTC)

Reasons for the above include that history tab of Long-run marginal cost has a much lower  Page view statistics than does Cost curve here.  Why not give this page more exposure?  The history of this article & Talk page can be put on the Talk:Cost curve prior to moving.  Comments welcome.  In the absence of a consensus against the merge, I propose merging Long-run marginal cost article into Cost curve article in a month.  --Thomasmeeks (talk) 18:40, 8 September 2010 (UTC)
