Chapter 4: Return and Risk
If the present value of the benefits just equals the cost, you would earn a rate of return equal to the discount rate If the present value of the benefits exceeds the cost, you would earn a rate of return greater than the discount rate If the present value of the benefits is less than the cost, you would earn a rate of return less than the discount rate

Required return on investment j = Real rate of return + Expected inflation premium + Risk premium for investment j
= Risk-free rate + Risk premium for investment j
Rj = r* + IP + RPj = RF + RPj
Risk-free rate = Real rate of return + Expected inflation premium RF = r* + IP

Total Product = Quantity (Q)
Average Product (AP) = Total Product (Q) / Labour (L)
Marginal Product (MP) = Change in Total Product / Change in Labour
Profit = Total Revenue (TR) – Total Costs (TC)
Profit = (Average Revenue – Average Cost) x Quantity
Total Revenue (TR) = Price (P) x Quantity (Q)
Total Costs (TC) = Total Fixed Costs (TFC) + Total Variable Costs (TVC)
Total Cost (TC) = Average Cost (AC) x Quantity (Q)
