Economic Assumptions
Overview
Basic economic models assume that consumers always buy whatever gives them the most satisfaction for their money, and that businesses always chase the largest possible profit. Real shoppers, though, often buy the same brand out of habit rather than comparing every option, and real managers sometimes chase growth, reputation, or an easy life instead of squeezing out every last cent of profit.
In this lesson you will look at the two founding assumptions behind most of economics, that consumers maximise benefit and producers maximise profit, and then examine why real behaviour so often departs from the tidy theory: what stops consumers acting in their own best interest, and what pulls a business away from pure profit-seeking.
Objectives
- The underlying assumptions that consumers aim to maximise their benefit and businesses aim to maximise their profit
- Reasons why consumers may not maximise their benefit: consumers are not always good at calculating their benefits, consumers have habits that are hard to give up, consumers sometimes copy others' behaviour
- Reasons why producers may not maximise their profit: producers may have managers that revenue maximise or sales maximise, producers may prioritise caring for customers, producers may complete charitable work
