Study the table above: What is the marginal product of the second worker?
- 10
- 20
- 15
-
18
- 43
The correct answer is: D
Explanation
is the change in output resulting from employing one more unit of a particular input, for instance, an increase in labour.
From the table above, when the firm had only 1 unit of labour, the output was 10. When it increased its labour to 2, the output increased to 28.
Therefore, marginal product of the second worker = 28 - 10 = 18
