Assume that for the entire business sector of a private closed economy, there are $0 worth of investment projects that will yield an expected rate of return of 25 percent or more. but there are $15 worth of investments that will yield an expected rate of return of 20–25 percent, another $15 with an expected rate of return of 15–20 percent, and an additional $15 of investment projects in each successive rate of return range down to and including the 0–5 percent range. if the real interest rate is 5 percent, what amount of investment will be undertaken?

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
