Fundamental Economic Concepts
Opportunity Cost:
The opportunity cost is the value of the next best alternative that a person or firm could have chosen instead of pursuing the current activity.
For example, if a farmer chooses to plant corn instead of raising cattle, the opportunity cost of the corn is the value of the milk or meat that could have been produced.
A higher opportunity cost implies that the activity is less efficient.
Marginalism:
Marginalism is a principle that states that changes in price will affect both the quantity supplied and the quantity demanded.
For example, if the price of a good increases, consumers will be willing to pay more for it, leading to an increase in demand.
However, if the price of a good decreases, consumers will be willing to pay less, leading to a decrease in demand.
Equi-Marginal Principle:
The equi-marginal principle states that when a good is consumed, the consumer will feel indifferent between consuming one more unit or consuming one less unit.
For example, if a consumer is choosing between eating one more cookie or one less, they will feel indifferent between choosing the cookie or not choosing it.
This principle implies that producers can offer the same quantity of output at various prices, as the consumer's willingness to pay does not change
