How does the concept of complements and substitutes in microeconomics impact consumer behavior and market dynamics?

The concept of complements and substitutes in microeconomics affects consumer behavior and market dynamics by influencing how consumers make choices between different products. Complements are products that are used together, while substitutes are products that can be used in place of each other. When the price of a complement or substitute changes, consumers may adjust their purchasing decisions, which can impact demand and prices in the market. This can lead to shifts in market dynamics and competition among producers.
