National Output and Economic Growth
National Income and national output are used interchangeably to mean the flow of new output produced by the economy in a time period.
The national wealth comprises al physical assets owned by the nations residents that have value. Part of the national income wears out in the course of producing a years income, known as capital consumption. To maintain the size of the capital stock so that the stock can create the same amount of income in the next years, there must be a replacement investment. If not, there will be negative economic growth.
In order for positive economic growth to occur though, investment above the replacement investment must occur. Gross investment comprises these two investments, so the investment that is not replacement investment is known as net investment. This increases the size of capital stock, facilitating long run economic growth.
