What are the factors that determine the equilibrium price and quantity of a substitute good in the market?

The equilibrium price and quantity of a substitute good in the market are determined by factors such as the prices of other goods, consumer preferences, production costs, and overall market demand and supply. When the price of a substitute good increases, consumers may switch to the substitute, affecting the equilibrium price and quantity. Additionally, changes in consumer income and preferences can also impact the equilibrium in the market for substitute goods.
