What is an opportunity cost?
The value of the next best alternative foregone.
Why do we have opportunity costs?
Land, labour, capital (money put into the business) and enterprise are limited resources
However our wants are unlimited
This causes scarcity
What is a trade off?
In business to achieve two things may not be possible, as there is only so much capital and only so much of other resources.
Essentially a trade off is a compromise.
