- Question 37 [ DIFFICULT] Consider two firms, both producing the same product, using the same production technology given by: q = √√K This production technology implies the following MRTS: K MRTS=AY ΔΧ L where K is the amount of capital used and L is the amount of labour used to produce output. It can be shown that this production technology implies the following minimised total cost function: TC = 2q√w√r where w represents the per-unit cost of labour and r represents the per-unit cost of capital. Suppose each firm can hire labour at $1 per unit and capital at $9 per unit. Each firm produces 90 units of output. One firm (Firm 1) chooses its input combination to minimise costs of production. However, Firm 2 instead produces output using twice as much labour as Firm 1. Compared to Firm 1, how much higher are Firm 2's cost of production? a) $270 b) $67.50 c) $275 d) $135 e) $132 Hint: It can be shown that the cost-minimising quantities of capital and labour (chosen by Firm 1) are K = 30…arrow_forwardwhat is the answer?arrow_forwardSuppose a local developer has built 24 houses so far this year at a total cost to the company of $4.8 million. If the company builds the 25th house, its total cost will increase to $5 million. Which of the following is correct? - all of the above - the marginal cost of the 25th house, if it is built, will be $200,000 - if the company can sell the 25th house for $250,000, then it should build it - for the first 24 houses, the average cost per house was $200,000arrow_forward
- QUESTION 16 Refer to Scenario 7.4 below to answer the question(s) that follow. SCENARIO 7.4: You own and are the only employee of a company that sells custom embroidered pet sweaters. Last year your total revenue was $120,000. Your costs for equipment, rent, and supplies were $30,000. To start this business you invested an amount of your own capital that could pay you a $50,000 a year return. Refer to Scenario 7.4. Your economic profit last year was -$20,000. $40,000. $70,000. $90,000.arrow_forwardcan you help me solve and give me step by step how you did it, i believe the answer is c=786.6arrow_forwardNote:- Do not provide handwritten solution.

- Suppose an economy that produces and consumes apples, bread, and toy-cars. In the following table are data for two different years. 2019 2020 Good Quantity Price Quantity Price Apples 50 Rs.50 60 Rs.60 Bread 200 Rs. 20 180 Rs.25 Cars 25 Rs. 100 30 Rs.140 a. Using 2019 as the base year, compute the following statistics for 2019 and 2020 in the table given below: Statistics 2018 2019 GROSS DOMESTIC PRODUCT Nominal GDP Real GDP GROWTH RATE Growth Rate of Nominal GDP Growth Rate of Real GDP PRICE INDICES GDP deflator Inflation rate using GDP deflator - CPI (a fixed-weight price index) Inflation rate using CPI b. How much did the cost of living rise between 2018 and 2019? Compare the answers given by GDP deflator and CPI. Explain the difference. c. Explain which price index (GDP deflator or CPI) should be used to adjust the salaries, budget or spending to counterbalance the changes in the cost of living? Why?arrow_forwardPlease answer in detail according to the picture. Show that the cost function is homogeneous of degree 1/(α+β) in output. How do the returns to scale (degree of homogeneity of the production function) relate to the propertiesof the cost function? Does this make sense to you? Explain clearly why.arrow_forwardsolve this onearrow_forward
- Let us consider the cost implications of the short-run production schedule from assignment number 7, where capital was fixed at 2 units of capital. Labor: 0 1 2 3 4 5 6 7 8 9 Output: 0 6 24 60 120 170 210 240 260 270 In this scenario, since we only have two inputs (Capital and Labor), and since the amount of capital is fixed, the cost of total cost capital would also be Total Fixed Cost (TFC) and since labor is variable, the total cost of labor would be Total Variable Cost (TVC). In that context, assume that the cost of capital is $40 per unit per period, while the cost of labor (or wage rate) is also $30 per unit of labor per period. (a) Use this information set up a diagram (using excel) that shows total cost (TC) and total variable cost (TVC) of the firm per period in the short run with the level of output on the horizontal axiarrow_forwardFill in the missing data to solve this problem.
