One can show that for a single-output technology, the production set Y is convex if and only if the production function f (z) is concave. Suppose that a rm produces one output, q, with a single input, 2:, according to the production function q : f (2) Output price is p > 0, input price is w > 0. The rm maximizes prot. Discuss the impor tance of the assumption of convexity of Y (concavity of f) by referring to the output supply function (q(p,w)), the input demand function (2(1), w)), and prot function \"Mp, w) of the rm when i) f(z) : , ii) f(2) = z or iii) f(z) = Z2
