Economics starts with scarcity. Scarcity is valuable (all resources are finite, but demand is infinite).
Economics is based on trade-offs (you cannot have A without giving up B).
What you give in a trade-off is the direct cost, and what you could have done with the direct cost is the opportunity cost.
Every transaction has a trade-off and an opportunity cost.
Economics is a way of thinking and solving problems. You learn to ask what’s the opportunity cost and the trade-off for every transaction.
Supply follows price. The more the price is raised, the more supply is available. The lower the price, the lower the supply.
A recession is 2 consecutive quarters of a drop in the GDP.
