What occurs when the price of a substitute good falls?

When the price of a substitute good falls, consumers are likely to buy more of that substitute instead of the original good. A substitute good is an alternative that can satisfy the same need or want, meaning that when its price decreases, it becomes more attractive to consumers compared to the higher-priced original good. As a result, the demand for the original good will typically decrease because consumers will shift their purchases towards the now cheaper substitute. This shift in consumer behavior directly impacts the demand for the original good, leading to a decrease in its demand as people opt for the more affordable alternative. This concept underlines the relationship between substitute goods in economics.
