- The following diagram depicts a firm's demand curve given the economy-wide demand, and its tangent isoprofit curve. The firm faces a linear demand curve. The workers' average product of labour X equals 1. At B, which of the following statements is correct? Price, p: dollars 80+ W = 60 Iso-profit curve Demand curve Production function: q = n Quantity, q: Employment, n, given a production function where APL = A=1 200 a) Profits are $16,000. b) The slope of the isoprofit curve is -0.4. c) The marginal rate of substitution is -0.1. d) The markup is 0.1.arrow_forwardConsider the following production function: Assume capital is fixed at K = 25. At what level of employment does the marginal product of labor equal zero? The marginal product of labor equals zero when L= q=48LK+20L2 3 (3) ₁³. (Enter a numeric response using an integer.)arrow_forwardConsider a producer who rents machines K at r per year and hires labor L at wage w per year to produce output Q, where Q= K 0.5+ L0.5 Suppose he wishes to produce a fixed quantity of Q at minimum rent. Find his factor demand functions. Show that the Langrange multiplier is given by Lambda = 2w r Q /(w + r). Suggest an economic interpretation for . Now let p denote the price of output . Suppose the producer now vary the quantity of output, and seeks to maximize profit. Show that his optimum output supply is Q = p(w + r) / (2 w r). Relate this to your interpretation of lambdaarrow_forward
- For the production function Q = K0.7L0.4 and the budget 146 = 7K+ 4L find the change in the optimal employment of L after wages change by a factor of 1.7. Please enter your response as a positive number with 1 decimal and 5/4 rounding (e.g. 1.15 1.2, 1.14 = 1.1).arrow_forwardPlease dont provide answer in handwritten solution...arrow_forwardIn the short run one half of the labour force has high skills and one half low skills (in terms of Figure 13.2 this means that the short-run supply curve is vertical at 0.5). The relative demand for the high-skill workers is given by W = 100×0.4×(1− f), where W is the wage premium and f is the fraction that is skilled. The premium is measured in percent. (a) Illustrate the supply and demand curves graphically, and compute the skill premium going to the high-skill workers in the short run by solving the two equations. (b) If demand increases to W = 100 × 0.6 × (1 − f) what is the new premium? Illustrate your answer graphically. Figure 13.2arrow_forward

Please enter your response as a positive number with 1 decimal and 5/4 rounding ( e.g. 1.15 = 1.2, 1.14 = 1.1). = K0.7L0.6 and thearrow_forwardSuppose the supply curve of lab assistants is given by w = 8 + 6E, while the demand curve is given by w = 40 – 2E. (Assume is in 000s of persons and w is the annual salary in thousands of dollars). Calculate the equilibrium wage and employment level.arrow_forward
- Please get correct.arrow_forwardA company has 350 employees who work 120 hours a month each. Each worker earns $21 per hour. There is a profitable project the company would like to start, but it would require an additional 21,000 working hours within three months to be completed, and all the employees are fully loaded with other projects. The company does not want to hire new staff; they would like the project to be completed by the current workforce instead.Given that the wage elasticity of labor supply is 0.8, calculate the hourly wage the company should offer its employees to encourage them to work on the new project. Use the midpoint method and round to two decimal places throughout your calculations.arrow_forwardQUESTION 1 For the production function Q = K0.1L0.1 and the budget 124 = 5K + 2L find the NEW LEVEL in the optimal employment of capital (K) after wages change by a factor of 0.5 while maintaining the same level of output. Please enter your response as a positive number with 1 decimal and 5/4 rounding (e.g. 1.15 = 1.2, 1.14 = 1.1).arrow_forward
