What is supply and demand in economics?

The concept of supply and demand forms the theoretical basis of modern economics. In situations where a firm has market power, its decision on how much output to bring to market influences the market price, in violation of perfect competition. There, a more complicated model should be used; for example, an oligopoly or differentiated-product model.

What are the principles of supply and demand?

The principles of supply and demand are effective in predicting market behavior. Whether an individual is a manufacturer or a consumer, the supply and demand equilibrium is relevant in daily market transactions. The law of supply and demand was popularized by Adam Smith in 1776. Consumer demand for a good commonly decreases as its price rises.

What is the law of supply and demand?
