Document Summary
The measurement of national income is central to our understanding of the level of economic activity. We can measure national income indirectly by measuring how much is produced in the economy. However, it is not as simple as just measuring the value of the output of all firms. This would lead to the problem of double counting. Measuring production as a means of measuring income. Consider the contribution of a load of bread to our measure of production . This includes the sale of wheat to the mill, the sale of flour to the baker, and finally the sale of bread to the consumer. If we add up the value of the output for all three transactions then we will overestimate (double count) the level of production. Instead, we should focus not on the sale price of the good, but rather the value added at each stage of production (value added approach) Value added = revenue cost of intermediate goods.
