3.1.4. Output Optimization and Maximization of Profit
Profit maximization occurs when the difference between total revenue (TR) and total costs (TC) is the greatest; marginal revenue (MR) equals marginal cost (MC); and the revenue value of the output from the last unit of input employed equals the cost of employing that input unit (as later developed in Equation 12). All three approaches derive the same profit-maximizing output level. In the first approach, a firm starts by forecasting unit s

Subject 1. NPV and IRR
y a capital investment. As such, it is an easy number to interpret and understand. However, calculation of the IRR assumes that all project cash flows can be reinvested to earn a rate of return exactly equal to the IRR itself. In other words, <span>a project with an IRR of 6% assumes that all cash flows can be reinvested to earn exactly 6%. If the cash flows are invested at a rate lower than 6%, the realized return will be less than the IRR. If the cash flows are invested at a rate higher than 6%, the realized return will

Modern portfolio theory makes frequent use of the idea that investment opportunities can be evaluated using expected return as a measure of reward and variance of return as a measure of risk.

Calculation of Portfolio Expected Return. Given a portfolio with n securities, the expected return on the portfolio is a weighted average of the expected returns on the component securities:

E(Rp)=E(w1R1+w2R2+…+wnRn)=w1E(R1)+w2E(R2)+…+wnE(Rn)
