Economics is the study of the organization of economic activities in society. Economics attempts to answer questions related to market prices, production and the gain of wealth. The field of economics is primarily interested in solving what is known as the basic economic problem. The basic economic problem states that while the desire of people is infinite, our resources are limited.
When something is both desired and limited, it is scarce. Economics deals with the concept of scarcity and answers questions about scarce goods. For example, the price of diamonds versus water can be explained through the concept of scarcity--diamonds are practically useless but scarce; water is extremely useful but plentiful.
Goods and Resources
Goods are those objects that people desire. To produce goods, you need resources. Economics is concerned with how resources affect our lives. To further define the concept of goods and resources, economists call goods created with scarce resources “economic goods” and goods created with plentiful resources “free goods.” The car is an example of an economic good while sunshine is an example of a free good.

This situation is called a tradeoff. Specifically, economists are interested in analyzing the tradeoffs related to economic goods.

Supply and Demand
Supply and demand is a concept familiar to many: those who offer goods or services compose the supply, and those who want those goods or services compose the demand. Economics researches how this idea of supply and demand determines the prices of goods
