Draw an isoquant-isocost line graph to illustrate the following situation and the change that occurs:
Ebba Kantzen can rent pizza ovens for $875 per week and hire workers for $500 per
week. Currently, she is using 4 ovens and 7 workers to produce 20,000 pizzas per week and has
total costs of $7,000. Then Ebba reorganizes the way things are done in her business and achieves
positive technological change.
week
Use the three-point curved line drawing tool to draw an isoquant curve for 20,000 pizzas per
prior to the technological change and an isoquant curve for 20,000 pizzas after the technological
change. Properly label the curves.
Carefully follow the instructions above, and only draw the required objects.

Based on the table you created in image, Choose one isoquant and compute two MRTS at least! (for an example from point A to B and from B to C)
When analyzing isoquants, if the marginal product of all inputs double, how would that change the input mix you would use to produce a given level of output?

- Q3) A chair manufacturer hires its assembly-line labor for $30 an hour and calculates that the rental cost of its machinery is $15 per hour. Suppose that a chair can be produced using 4 hours of labor or machinery in any combination. Graphically illustrate the isoquant and the two isocost lines for the current combination of labor and capital and for the optimal combination of labor and capital.arrow_forwardIsoquant curves and isocost curves are tools that can explain how a firm might best respond to changes in the production environment. Present an example of an isocost curve where labor and capital are the two inputs, and explain what it is using language someone not trained in economics could understand. Present an example of an isoquant in the same diagram you used for your isocost curve, and draw the isoquant so it cuts the isocost curve twice. Explain what an isoquant is using language someone not trained in economics could understand. Label the two points A and B, where the isocost and isoquant curves intersect. Present a logical argument that explains why the firm should operate neither at point A nor point B, and present a point that would be optimal by drawing a new isoquant curve in the diagram. Add a second isocost curve to your diagram such that the firm is spending more money on inputs. Add a third isoquant to your diagram to show a firm that would become more capital…arrow_forwardIsoquant curves The Firm can trade two doctors for five gardeners and output remains constant What is the shape is the isoquant curve for the firm?

Move the production slider to 6 units of labor. Suppose you had the information for the L=2 row and the L=6 row, but the row(s) in between them were missing and you didn't have any information in the Marginal Product column. If you wanted to estimate the marginal product, you might assume the marginal products of each of the 4 additional workers are equal. a. Estimate the marginal product of each additional worker if L were to increase from 2 to 6. b. Calculate the slope of the total production function between L=2 and L=6.arrow_forwardLauren runs a chili restaurant in San Francisco. Her total revenue last year was $110,000. The rent on her restaurant was $48,000, her labor costs were $42,000, and her materials, food and other variable costs were $20,000. Lauren could have worked as a biologist and earned $50,000 per year. An economist calculates her implicit costs as A) $110,000. B) $50,000. C) $63,000. D) $150,000.arrow_forward
