Economics is the study of how society manages its scarce resources. It addresses three fundamental questions: 

  • What goods and services will be produced? 
  • How will they be produced? 
  • Who will receive them? 
Because people’s wants are virtually unlimited, but resources such as land, labor, and capital are limited, choices must be made, leading to problems of scarcity and resource allocation. An economic system is the specific set of institutions, strategies, and methods used to manage economic activities. It strives to answer what, how, and for whom various commodities and services should be produced. The three main types of economic systems are capitalism, socialism, and mixed economy
