Cost, Supply, and Farm Structure: A Pedagogical Note

Teigen, Lloyd D. - In: Journal of Agricultural Economics Research, 1

Starting with an individual firm and its quadratic production function, this paper derives all related functions marginal and average cost, supply, profit, and input-demand. Since derivatives in other functions correspond to parameters of the quadratic, the results generalize. Explicit...
