Question 20 Output Input 2 pts In this diagram below, showing the relationship between a specific input and the resulting output, diminishing marginal returns begins to set in after units of input. Question 21 Refer to the diagram in the above question. Diminishing total returns begins to set in after units of input. 2 pts Question 22 Use the Resource Sheet for Test #2 to help you fill in the 10 blanks for this question. Imagine a planet with only two countries, call the A & B. Suppose that each country as the productive capacity to produce $1,000 of consumer goods per period. Additionally, each country has the technological capability to build nuclear weapons, but such an investment would cost $200. If one country did invest in nuclear armaments while the other did not, it could take half of the other country's stock of consumer goods. If the other country also had a nuclear capacity, it could thwart any threat of invasion, extortion or intimidation. Complete the payoff matrix with the appropriate values and answer the question: Which cell represents the mutually beneficial outcome? Which cell represents the equilibrium outcome?
