Principles OF Economics and difference..

The principles of economics are fundamental concepts that guide how individuals, businesses, and governments make decisions about resource allocation. Key principles include scarcity, which highlights that resources are limited; opportunity cost, referring to the value of the next best alternative forgone when a choice is made; supply and demand, which determine prices in markets; and marginal analysis, where decisions are made based on the additional benefit or cost of one more unit. These principles help explain how economies function, how prices are set, and how individuals and societies maximize their welfare given limited resources
