What is an economist view of cost?

An economist views cost as the value of the next best alternative foregone when a choice is made, often referred to as opportunity cost. This perspective emphasizes not just the monetary expenses but also the trade-offs involved in resource allocation. Economists analyze costs in terms of both explicit costs (direct monetary payments) and implicit costs (the value of missed opportunities). Ultimately, understanding costs helps in assessing the efficiency and effectiveness of decisions in resource use.
