What effect do rising disposable incomes due to an increase in the gross domestic product have on product demand?

Increase in demand for products

Interest rates, inflation rates, changes in disposable income of people, stock market indices and the value of rupee are some of the economic factors that can affect management practices in a business enterprise. Short and long term interest rates significantly affect the demand for product and services. For example a rise in the disposable income of people due to increase in the gross domestic product of a country creates increasing demand for products.
