What is the role of substitute goods in economics and how do they impact consumer behavior and market dynamics?

Substitute goods are products that can be used in place of each other. In economics, they play a significant role in influencing consumer behavior and market dynamics. When the price of one substitute good increases, consumers tend to switch to the cheaper substitute, leading to a decrease in demand for the more expensive product. This can impact market dynamics by affecting prices, competition, and overall consumer choices.
