Sagot :

1. David's decision to buy electronics represents an opportunity cost.

Opportunity costs are the potential benefits that an individual, investor, or business foregoes when choosing one alternative over another. Because opportunity costs are by definition invisible, they are easily overlooked. Understanding the potential missed opportunities when a company or individual chooses one investment over another allows for more informed decisions.

2. The hiring of another economist is based on marginal analysis.

The process of breaking down a decision into a series of 'yes or no' decisions is known as marginal analysis. It is a formal examination of the additional benefits of an activity in comparison to the additional costs incurred by that same activity.
