The relation between the shapes of productivity and cost curves. Give a comparisonbetween the APP curve with

Explanation of Solution
The production curve, which is the APP curve, has input on the horizontal axis and output on the vertical axis. Now, when the input changes, the output reacts and the curve is made. In other words, when there is an increase in the inputs, output rises at the initial stage at higher rate, then at slower rate, and after a stage starts declining. On the other hand, in the cost curve, which is ATC curve, the output is represented on the horizontal axis and cost of input is represented on the vertical axis. In this curve, in the starting stage, the cost decreases at a higher rate, then at a slower rate and after a stage starts increasing when the production of output is raised.
The production curve, which is MPP curve, is same as the APP curve and has the same curve and trend on the curve. On the other hand, cost curve, which is the MC curve, is same as ATC curve and has the same curve and trend on the curve.
Productivity Curve:
This curve shows that when there is an increase in the variable resources, then in the initial stage, output increases at a higher rate, then at a slower rate, and then after a stage it may start to decline. The reason behind these changes is the law of diminishing marginal returns.
Cost Curves:
This curve shows the changes in the cost of production at each level of output, which means in the initial stage, cost of production decreases at a higher rate, then at a slower rate, and then after a stage it starts increasing. The reason behind this is also the law of diminishing marginal returns.

- 1. Imagine a society that produces military goods and consumer goods, which we'll call "guns" and "butter." a. Draw a production possibilities frontier for guns and butter. Using the concept of opportunity cost, explain why it most likely has a bowed-out shape. b. Show a point that is impossible for the economy to achieve. Show a point that is feasible but inefficient. c. Imagine that the society has two political parties, called the Hawks (who want a strong military) and the Doves (who want a smaller military). Show a point on your production possibilities frontier that the Hawks might choose and a point the Doves might choose. d. Imagine that an aggressive neighboring country reduces the size of its military. As a result, both the Hawks and the Doves reduce their desired production of guns by the same amount. Which party would get the bigger "peace dividend," measured by the increase in butter production? Explain.arrow_forwardA health study tracked a group of persons for five years. At the beginning of the study, 20%were classified as heavy smokers, 30% as light smokers, and 50% as nonsmokers. Resultsof the study showed that light smokers were twice as likely as nonsmokers to die duringthe five-year study, but only half as likely as heavy smokers.A randomly selected participant from the study died during the five-year period.
