Study Session 4: Economics: Microeconomic and Macroeconomics

Price Indexes - required or not?

Reading 15 - Firm and market structures - Practice Problem 5

Hi All,

I have the following question that I would like to understand :

The demand schedule in a perfectly competitive market is given by P = 93 – 1.5Q (for Q ≤ 62) and the long-run cost structure of each company is:
Total cost:     256 + 2Q + 4Q2
Average cost:     256/Q + 2 + 4Q
Marginal cost:     2 + 8Q

New companies will enter the market at any price greater than ? : 66

My questions are :

Demand

The monthly demand curve for playing tennis at a particular club is given by the following equation: PTennis Match = 9 − 0.20 × QTennis Match. The club currently charges members $4.00 to play a match but is considering adding a membership fee. If the club continues to charge the same per play charge, the most that it will be able to charge as a membership fee is closest to:

  1. $62.50.
  2. $162.50.
  3. $40.00.

Solution

A is correct. On rearrangement, the demand function is:

AD / AS - Difference between Price Level, Output Price, and Input price?

Working through the Macroeconmics section and not entirely understanding this:

Looking at the Aggregate Supply Curve(s) - when they speak of Price Level, vs Input Price vs Output Price.  

How can I think about each (how are they entirely different) from the AS point of view?  

Price Level:

Input Price:

Output Price:

Been 20 years since I tackled macro, slowly coming back to me….. thank you.
