Competitive Pricing Techniques
![Page 2: Economics of the Firm Competitive Pricing Techniques.](https://reader038.fdocuments.in/reader038/viewer/2022103123/56649d695503460f94a47679/html5/thumbnails/2.jpg)
Every business has a goal. What’s the goal of your business?
“To Make Money!!!”
Maximize Profits
Increase Market Share
Maximize Shareholder Value
Maximize return on investment
To be a leader in technology
To be “Green”
Optimal decision making (for example, pricing) depends crucially on what your goal is!
![Page 3: Economics of the Firm Competitive Pricing Techniques.](https://reader038.fdocuments.in/reader038/viewer/2022103123/56649d695503460f94a47679/html5/thumbnails/3.jpg)
TCPQ
We will be assuming that pricing decisions are being made to maximize current period profits
Total Revenues equal price times quantity
Total Costs (note that total costs here are economic costs. That is, we have already included a reasonable rate of return on invested capital given the risk in the industry)
Profits
![Page 4: Economics of the Firm Competitive Pricing Techniques.](https://reader038.fdocuments.in/reader038/viewer/2022103123/56649d695503460f94a47679/html5/thumbnails/4.jpg)
As with any economic decision, profit maximization involves evaluating every potential sale at the margin
How do my profits change if I increase my sales by 1?
How do my revenues change if I increase my sales by 1? (Marginal Revenues)
How do my costs change if I increase my sales by 1? (Marginal Costs)
TCPQ
Lets take this piece by piece
![Page 5: Economics of the Firm Competitive Pricing Techniques.](https://reader038.fdocuments.in/reader038/viewer/2022103123/56649d695503460f94a47679/html5/thumbnails/5.jpg)
We will treat costs as a given. Every firm has a total cost function.

For every price I could charge, my demand curve tells me what my sales will be.

For any sales goal that I set, my demand curve will tell me what price I can charge to obtain that goal

D
Next, we need to know something about the consumer the firm faces. Every firm should have an estimated demand curve. We can think about a demand curve in one of two ways
![Page 7: Economics of the Firm Competitive Pricing Techniques.](https://reader038.fdocuments.in/reader038/viewer/2022103123/56649d695503460f94a47679/html5/thumbnails/7.jpg)
So, we can get firm revenues one of two ways:
I select a sales target
My demand curve will tell me the sales I will achieve at that target
TQ )( TQPP
Revenues equal price times quantity
TPQTR
I select a price target
My demand curve will tell me the price I can charge to hit that target
TP )( TPQQ

In either case, higher sales will be associated with a lower price
TPQTR QPTR T
If I want to increase my sales target, I need to lower my price to all my existing customers
OR
I need to drop my target price if I want to reach new customers

An industry’s cost structure will influence an industry’s competitive nature
Q
Costs
MC
AC
If market size is small, this industry experiences decreasing costs (big firms have an advantage over small firms)
However, if the industry gets big enough, costs start to increase and the size advantage becomes a disadvantage!

Industries with globally scale economies tend to develop as natural monopolies (the market should – and will – be serviced by one producer). This can happen if production exhibits increasing marginal productivity, or if there are large fixed costs.
![Page 33: Economics of the Firm Competitive Pricing Techniques.](https://reader038.fdocuments.in/reader038/viewer/2022103123/56649d695503460f94a47679/html5/thumbnails/33.jpg)
Monopoly Market Characteristics
Small market size
Scale economies (Network Externalities, Learning by Doing, Large Fixed Costs)
Government Policy (Protected Monopolies)
Any one of these characteristics suggest that the market structure could be monopolistic.

Case Study: Microsoft vs. Netscape
The argument against Microsoft was using its monopoly power in the operating system market to force its way into the browser market by “bundling” Internet Explorer with Windows 95.
To prove its claim, the government needed to show:
•Microsoft did, in fact, possess monopoly power
•The browser and the operating system were, in fact, two distinct products that did not need to be integrated
•Microsoft’s behavior was an abuse of power that hurt consumers
What should Microsoft’s defense be?
