Begin by discussing the Profit Maximization model and its corresponding formula Ï= pq - cq. Think of a product you might buy in bulk from a store like Costco. Think about how much the price is per unit and what you think the cost per unit might be. How many units come in a bulk container of your product? What would the profit be, based on your assumptions about the costs and price of the product?

Next, market prices are set based on the supply and demand of a good or service, rather than by some external decision-making entity. This is because people are seeking to maximize their utility and businesses seek to maximize their profit, and the goal of a functioning market is to find that point where utility gets as high as it can without dipping into the profit margin. This interplay of people's desires and the amount available create what was called by Scottish Enlightenment philosopher Adam Smith as the "invisible hand" of God in his book The Wealth of Nations. Hopefully, the end result will be equilibrium as indicated in the Marshallian Supply-Demand Cross. Government, meanwhile, seeks to maximize the public welfare, and steps in when there are certain economic outcomes desired but not being met - in what we refer to as socialism (note: every capitalistic country engages in some degree of socialism - it is the extent to which that occurs that decides whether we call the country capitalist or socialist). What happens to the invisible hand when the government steps in?

Which of the following is not necessarily a characteristic of perfect competition? (Points: 1)

low prices
a large number of buyers and sellers
a homogeneous product
perfect information

2. In the short run, a perfectly competitive ball bearing manufacturer will continue to produce at a loss if (Points :1)
it is covering all of its variable cost plus part of its fixed cost

it is covering all of its fixed cost
variable cost is less than the fixed cost
fixed cost is zero

3. The golden rule of profit maximization states that any firm maximizes profit by producing where (Points :
marginal revenue equals marginal cost
demand is unit elastic, and total revenue is the greatest
price equals marginal revenue
price equals marginal cost


4. Which of the characteristics of perfect competition assures that economic profit will be zero in the long run? (Points: 1)
There are easy entry and exit in the market.
Each firm is a price taker.
Each firm has access to perfect information.
Each firm is small relative to the market.


5. A constant-cost industry is distinguished by the fact that(Points: 1)
firms' short-run average total costs are horizontal
firms' short-run marginal cost curves are horizontal
the long-run industry supply curve is perfectly elastic
the short-run industry supply curve is perfectly elastic


6. Commodity products are (Points: 1)
pasteurized
bland
perceived by consumers to be identical
made by one manufacturer


7. In a perfectly competitive industry we are likely to find(Points: 1)
firms producing a wide variety of products
barriers to entry
no profit possible in the short run
firms that do not advertise


8. Perfectly competitive firms are price takers because (Points :1)
all small firms must take the price set by the largest firm in the market
firms take the price that government determines is a "fair" price
each firm is small and goods are perfect substitutes for one another
free entry and exit in the short run creates a constant market price in the long run


9. In perfect competition, if one firm raises its price, (Points :1)
others will follow
that firm will increase its revenues
that firm will lose revenues because other firms will not follow
all consumers will be adversely affected


10. Suppose, at its present rate of output, a perfectly competitive firm's marginal revenue exceeds both its marginal cost and its average variable cost. To maximize profit, the firm should (Points: 1)
lower the price
raise the price
increase output
reduce output
