Setrite Corporation manufactures chairs. An economist at the company forecasts that if consumers' incomes increase next year, the demand for Setrite's chairs will rise, assuming all other factors remain constant. The accuracy of this forecast depends on whether the chairs are considered which type of good?
Explanation
The prediction that demand will increase with rising incomes holds true if the chairs are normal goods, meaning demand rises as consumer income grows. If the chairs were inferior goods, demand would decrease with higher income. The number of substitutes or complements does not directly affect this income-demand relationship.
