JNU SSS 2012 Question 67: Factor markets and income distribution
A firm uses labour to produce a certain good. If x units of labour are used by the firm, the output of the good equals f(x)=20x−x2. Each unit of the good sells at a price of 1. Let w denote the price of each unit of labour. We must have x≥0. Assume that the firm hires labour to maximize profits.
What is the minimum w for which it is optimal for the firm to hire zero unit of labour?

Plain-text version
A firm uses labour to produce a certain good. If x units of labour are used by the firm, the output of the good equals f(x) = 20x - x². Each unit of the good sells at a price of 1. Let w denote the price of each unit of labour. We must have x ≥ 0. Assume that the firm hires labour to maximize profits. What is the minimum w for which it is optimal for the firm to hire zero unit of labour? (A) 0 (B) 10 (C) 15 (D) None of the above
Also written as: A firm uses labour to produce a certain good. If x units of labour are used by the firm, the output of the good equals f(x) = 20x - x^2. Each unit of the good sells at a price of 1. Let w denote the price of each unit of labour. We must have x >= 0. Assume that the firm hires labour to maximize profits. What is the minimum w for which it is optimal for the firm to hire zero unit of labour?
