Capital output ratio refers to __________________.
A frequently used tool that explains the relationship between the level of investment made in the economy and the consequent increase in GDP is the capital-output ratio. The concept of the capital-output ratio expresses the relationship between the value of capital invested and the value of output.
Capital output ratio is the amount of capital needed to produce one unit of output. For example, suppose that investment in an economy, investment is 32% (of GDP), and the economic growth corresponding to this level of investment is 8%.
Here, a Rs 32 investment produces an output of Rs 8. Capital output ratio is 32/8 or 4. In other words, to produce one unit of output, 4 unit of capital is needed. But don’t forget that the Rs 32 invested in the form of machinery will remain there for around ten or twelve years. Such machinery will be giving Rs 1 output in every year.
Hence, B is the correct option.
