can i know how we get this formula for investment?
and what each letter in the formula represent?
thanks
As we know, Investment may be autonomous and induced.
Autonomous Investment = If the investment does not depend either on income/output or the rate of interest, then such investment is called autonomous investment.
Induced Investment = Investment that is dependent on the level of income or on the rate of interest is called induced investment.
Here 2 cases arise, Y shows the Income
1st if the I on the right side is the investment =
2nd if the I on the right side is Rate of Interest =
Investment is inversely related to the level of interest rate
Investment is directly related to Income.
