Question
Explain the concept of effective demand using a hypothetical table & curve.
Solution
Effective demand refers to the amount of a product or service that consumers are willing and able to purchase at the current market price. It is determined by the intersection of the demand and supply curves in a market.
Let's illustrate this concept with a hypothetical table and curve.
Table:
| Price ($) | Quantity Demanded | Quantity Supplied |
|---|---|---|
| 1 | 1000 | 500 |
| 2 | 800 | 600 |
| 3 | 600 | 600 |
| 4 | 400 | 700 |
| 5 | 200 | 800 |
In this table, we can see that at a price of $3, the quantity demanded equals the quantity supplied. This is the point of effective demand.
Now, let's plot this on a graph:
- Draw the x-axis (quantity) and y-axis (price).
- Plot the demand curve using the price and quantity demanded data. The demand curve will slope downwards, indicating that as price increases, quantity demanded decreases.
- Plot the supply curve using the price and quantity supplied data. The supply curve will slope upwards, indicating that as price increases, quantity supplied also increases.
- The point where the demand and supply curves intersect is the point of effective demand. In this case, it's at a price of $3 and quantity of 600.
This point of intersection indicates the market equilibrium where the quantity of goods consumers are willing to buy equals the quantity that suppliers are willing to sell. This is the concept of effective demand.
