What is the relationship between investment and the real rate of return?This Q is in economics class. this Q is under Basic Macroeconomic...

The real rate of return on an investment is basically the
percentage of the investment that you get back each year, adjusted for inflation.  In
other words, the real rate of return is a good way of determining how much money you
truly made from an investment over a given time.

The
relationship between this and investment is that investors are seeking a high real rate
of return.  An investor will buy investments that are likely to give such a rate of
return.  So, the higher the anticipated real rate of return, the more likely investors
are to buy a given investment product.
