Income (Y) Consumption (C) Investment (I) Aggregate Demand (AD) 0 50 40 90 100 120 40 – 200 190 40 – 300 260 40 300
Define the term ‘Effective Demand’.
Assuming for a hypothetical economy, the following data is given :
| Income (Y) | Consumption (C) | Investment (I) | Aggregate Demand (AD) |
|---|---|---|---|
| 0 | 50 | 40 | 90 |
| 100 | 120 | 40 | – |
| 200 | 190 | 40 | – |
| 300 | 260 | 40 | 300 |
Define the term ‘Effective Demand’.

Solution and Explanation
In macroeconomics, Aggregate Demand (AD) is the total planned spending on goods and services. Aggregate Supply (AS) is the total value of output that firms plan to produce.
Step 2: Definition:
Effective Demand is that level of Aggregate Demand which is met by the matching Aggregate Supply in the economy.
At this level, what buyers plan to spend equals what firms plan to produce.
Step 3: Link with the given schedule:
In the schedule, income Y is the same as aggregate supply. We look for the row where AD equals Y.
At Y = 300, AD is 300. So AD equals AS only at 300.
At Y = 100 and Y = 200, AD is 160 and 230. Both are more than income, so those AD levels are not matched by supply.
Step 4: Value of effective demand here:
Effective demand in this example is 300.
Final Answer:
Effective Demand is the level of AD that is met by the corresponding AS in the economy. In the given data it is 300.
