Economic Concepts of Marginal Revenue and Pricing
Chapter 1: Introduction
- Marginal Revenue: The additional revenue gained from selling one more unit of a good. In the example:
- Price per unit = 9
- Units sold = 6
- Revenue calculation: 9 imes 6 = 54
- Marginal revenue from selling the sixth unit = 4
- Discusses the difference in pricing strategies between monopolies and perfectly competitive firms.
Chapter 2: Lower The Price
- Price vs. Marginal Value:
- Important to note: Price is not equal to marginal value in some market structures.
- To increase sales from five to six units, the firm must lower the price on all units due to a downward sloping demand curve, leading to different marginal revenues.
- Questions to ask:
- What happens to pricing when demand changes?
- Why do buyers influence pricing?
Chapter 3: Drop The Price
Impact of Price Drop:
- If the firm sells going from five to six units:
- Original price for five units: 10 per unit.
- New price for six units: 9, which means the first five units' price must also drop to 9 to sell the sixth unit.
- Loss per unit due to the price drop = 10 - 9 = 1.
- Thus, total loss from the first five units when selling six units = 5.
- Final Marginal Revenue = 9 - 5 = 4.
Revenue Components:
- The intersection of price and quantity leads to two effects:
- Price effect: The change in revenue due to the change in price for all units sold.
- Quantity effect: The change in revenue due to selling one more unit.
Conclusions About Revenue:
- Increase in quantity sold can lead to increased revenue.
- Decreasing prices generally leads to decreased revenue.
Chapter 4: Conclusion
- Inverse Relationship:
- Reducing the quantity sold raises the price, affecting overall revenue in the opposite direction.
- Patterns to Recognize:
- Recognizing how quantity and price changes affect marginal revenue is crucial.
- Suggestion to practice with tables to understand the formulas and calculations involved in marginal revenue analysis.
- Recommendation:
- Familiarize oneself with key formulas and practice problems to solidify understanding.
