Explanation of Solution

Figure 1 illustrates the PPF of Company B.

Macroeconomics, Chapter 2, Problem 1SPA

In Figure 1, the x-axis shows food crops and the y-axis shows ethanol. The PPF shows the production combinations of ethanol and food crops. The production combinations of these commodities lie beyond the PPF and are not attainable with the given resources; this indicates the concept of scarcity. The movement along the PPF also indicates scarcity because when one good produces more, other goods are reduced.

Economics Concept Introduction

Scarcity: Scarcity refers to the limited availability of resources than the required level.

Production possibility frontier: Production possibility frontier shows the boundary between the combination of two goods and services that can produced at the given level of resources.

(b)

To determine

Identify the concept of production efficiency.

(b)

Explanation of Solution

A production possibility frontier shows the combination of two commodities that can be produced at the given level of resources. Therefore, the combinations of commodities that lie along the PPF indicate efficient production levels. In this case, if Company B produces 40 barrels of ethanol per day, then the production of food per day needed to achieve the production efficiency will be 3 tons.

Economics Concept Introduction

Efficient production: Efficient production shows the combinations of two commodities that lie along the PPF.

(c)

To determine

Identify the concept of tradeoff in a PPF.

(c)

Expert Solution
Check Mark

Explanation of Solution

A movement along the PPF curve explains that producing more of one good leads to producing less of another good. Therefore, there is a tradeoff that exists between the commodities; it is also noted that this type of tradeoff exists only at an efficient production level. In this case, Company B has limited resources and technology. Therefore, an increase in the production of one good decreases the production of the other good. As a result, Company B will face a tradeoff on its PPF.

Use a game tree to illustrate why an aircraft manufacturer may price below the current marginal cost in the short run if it has a steep learning curve.   ​(Hint​: Show that learning by doing lowers its cost in the second​ period.) Part 2 Assume for simplicity the game tree is illustrated in the figure to the right. Pricing below marginal cost reduces profits but gives the incumbent a cost advantage over potential rivals.
