A well-known financial writer argues that he can earn 148 percent per year buying wine by the case. Specifically, he assumes that he will consume one $12 bottle of fine Bordeaux per week for the next 12 weeks. He can either pay $12 per week or buy a case of 12 bottles today. If he buys the case, he receives a 9 percent discount and, by doing so, earns the 148 percent. Assume he buys the wine and consumes the first bottle today. Calculate the EAR.

Answer:

EAR = 148%

Explanation:

calculating the EAR ( applying the formula for present value of annuity )

cost of case = 12 * 12 * ( 1 - 0.09 ) = 131.04

Pv   =  131.04

cost per case =  $12

no of weeks = 12 weeks

rate of the wine per ( IRR ) = IRR(57;56;55;;;;1)=  1.76319

rate of the wine per week = 1.76319%

therefore EAR = ( 1 + 0.0176319) ^52 - 1 = 148.15% ≈ 148%
