To estimate GDP you add the value of all the goods and services produced, both final and intermediate goods. Is this procedure correct? Why or why not? Explain. To estimate GDP this might not be the correct procedure. When calculating GDP we are not supposed to take intermediate goods into the count of Gross domestic production. The market worth of all final products and services generated in the economy is measured by GDP. These items are not included in the computation since they would be recorded twice. If somebody who prepares the final product buys raw material from the market and after the final if it is counted again then it will be tallied twice in the counting and making it overstated or overestimated in final figures. If only final products are taken into account then all the materials are counted as one.
