The interest has no effect on the investment; because in reality, it affects the goods in the future, and the investment is in the present.
This does not remove the fact that interest rates are an indicator and are taken into account by investors, it is the allocation of real savings that allows investment to be possible. The more savings are allocated to the investment, the greater will be and in this the interest rates have no influence: if they are high or low, the amount destined for savings for investment will be a decision made independently of the interest rates, it will be taken in As to what is going to be invested, the objective to achieve and what is possible to allocate to invest.
