In the event the X try an item and you will Y are the replacement product, following exactly what will function as aftereffect of reduced amount of the purchase price away from Y product into interest in product X ? Describe with the aid of a diagram. Answer: When you look at the substitution effect, brand new product one becomes cheaper, is going to be substituted for apparently high priced item. Should your price of product Y decreases, then your demand for product X wil dramatically reduce, since the consumer tend to replace item Y instead of commodity X.
It is clear from the figure that when the price of commodity Y was OP the demand for commodity X was OQ When the price of commodity Y decreases to OP1 the demand for commodity X becomes OQ1 The demand curve for substitution goods is positive.
