question
Marginal Cost
answer
Refers to the rate of change of total cost with respect to output and often depends on the total volume of output.
question
If the average cost curve is increasing, must the marginal cost curve lie above the average cost curve? Why or why not?
answer
If the average cost curve is increasing, the marginal cost curve will lie above it because as
things are added to a group, if the average increases because of the most recently added thing, that "'marginal" thing must be greater than the average.

question
4. What is the difference between economic profit and accounting profit?
answer
The difference between accounting profit and economic profit is in how total cost is measured. With accounting profit, total cost is measured as total accounting cost, whereas with economic profit, total cost is measured as total economic cost. Accounting cost measures the historical expenses the firm incurred to produce and sell its product, whereas economic cost measured the opportunity cost of the resources that the firm uses to produce and sell its product.
question
Why should managers focus mainly on economic profits?
answer
If a firm chose to produce and sell a product it could earn a positive accounting profit but
negative economic profit. This would occur if the economic cost of the re sources used was
greater than the accounting cost of the re sources used.
For example, the firm might purchase
resources for $1 million and use these to produce a product when instead the firm could have
resold the re sources for $2 million. In this case, the economic cost exceeds the accounting cost
and economic profit would be less than accounting profit.

question
Why is marginal revenue less than total revenue?
answer
Marginal revenue is the amount at which each additional unit is sold. This will always be less
than the cumulative amount which is represented as total revenue.
than the cumulative amount which is represented as total revenue.
question
Why does the elasticity of demand affect a firm's optimal price?
answer
The supply elasticity can be used to determine the extent to which the equilibrium price will change
when demand shifts exogenously. If supply is elastic, then a shift in demand will have a smaller
impact on the equilibrium price than when supply is inelastic.

question
Explain why long-run prices in a perfectly competitive market tend toward the minimum
average cost of production.
average cost of production.
answer
If firms are making a profit, competitors will enter. As more quantity is made available, prices are
driven down until minimum average cost is the same as marginal cost. Once price hits this point,
competitors will cease to enter as it will no longer be profitable. This can be seen in Figure 1.14.

question
Is the prisoners' dilemma always a Nash equilibrium? Is a Nash equilibrium always a prisoners' dilemma? Explain.
answer
A prisoners' dilemma game illustrates the conflict between self-interest and collective interest. In
the Nash equilibrium of a prisoners' dilemma game, each player chooses a non-cooperative action even though it is in the players' collective interest to pursue a cooperative action.
If players chose strategies that did not constitute a Nash equilibrium, then the players could
choose another strategy that increased their payoff given the strategies chosen by the other
players. Since players could increase their payoffs by choosing other strategies, strategies that
do not constitute a Nash equilibrium are an unlikely out come in a game.
No, not every game in the chapter is a prisoners' dilemma. A Nash equilibrium in a game occurs
when each player chooses a strategy that gives it the highest payoff, given the strategies chosen by
the other players in the game.

question
Explain what we mean by "semi-fixed costs" and provide unique examples.
answer
Costs that are fixed over a RANGE of output. Ex. A delivery van can hold 30 boxes.
If the factory needs to deliver 60 boxes they need 2 vans. If the volume increases to
65 they need 3 vans.
If the factory needs to deliver 60 boxes they need 2 vans. If the volume increases to
65 they need 3 vans.
question
What are the formulas for TC, AC, MC, AVC, AFC, SR-ATC (SAC), TR, MR (both formulas), MP. If I gave you data (on an exam) you should be able to calculate any of these.
answer
See text for definitions. Note the textbook formula for MC is overly complicated ... it is
just (the change in TC / the change in Q). Also notice how these formulas are related.
That is, to get ATC, AVC or AFC just that the corresponding cost (like TC) and divide
by Q.

question
Explain the relationship between the shape of the average cost curve and economies of scale, diseconomies of scale, and constant returns to scale
answer
We have a slide on this. Also see figure 1.3 in the text.
Economies of scale, diseconomies of scale, and constant returns to scale are all related terms that describe what happens as the scale of production increases. It is important to understand the concepts of these returns to scale because they can be an important factor in determining the optimal and equilibrium size of firms. From that decision, the structure of industries and their prices and output levels can also be determined appropriately
Economies of scale:
This term characterizes a production process in which an increase in the number of units produced causes a decrease in the average cost of each unit.
Constant returns to scale:
It refers to a technical property of production that examines changes in output subsequent a proportional change in all inputs (where all inputs increase by a constant).
Diseconomies of scale:
A term used to describe processes that do not conform to the definition of economies of scale due to the costs for production does not decrease with the increased production.

question
Calculate price elasticity of demand, and be able to interpret a given elasticity value sentence (e.g. "if the PED of beer is 2.0, a 1% increase in the price of beer
will result in a ____________.")
will result in a ____________.")
answer
Know the formula for elasticity: % change in Q / % change in P
Answer to the above question is 2% decrease in sales of beer (aka quantity demanded of beer). So elastic demand in that price range.
Answer to the above question is 2% decrease in sales of beer (aka quantity demanded of beer). So elastic demand in that price range.

question
Make/Buy Decision
answer
1.) Asses whether the market provides any any alternative to vertical integration
2.) If no, the firm must either take on the task itself or prop up a quasi-independent supplier through a joint venture or strategic alliance
