When analyzing the process of the exchange of goods and services, one must not ignore the law of demand.
Explanation:
The law of demandis a concept from microeconomics stating that price and quantity of goods and services are inversely proportional while other factors remain unchanged. This means that, when the price of a product decreases, the demand for it increases, and the other way around. It is natural that consumers are more likely to purchase a product when its price is lower, thus increasing the demand for it.
