Data for Example MaLa Toy Corporation - Introduction of New Toy Estimate of revenues = $2,000,000 Estimates of costs of new toy = $1,000,000 or $2,500,000, with equal probabilities Cost of developing specialized information system to help predict toy costs = $40,000 Cost prediction is 80% accurate with specialized information system
Mala Toy Corporation Information Economics Prediction without Specialized Information System Revenues = $ 2,000,000 Costs = $ 1,000,000 Probability (p) = 0.5 Low Costs High Costs Costs = $ 2,500,000 p = 0.5 EV = ($ 2,000,000 - $ 1,000,000)*.5 + ($ 2,000,000 - $ 2,500,000)*.5 = $ 250,000
Mala Toy Corporation Information Economics Prediction without Specialized Information System Revenues = $ 2,000,000 Costs = $ 1,000,000 Probability (p) = 0.5 Low Costs High Costs Costs = $ 2,500,000 p = 0.5 EV = ($ 2,000,000 - $ 1,000,000)*.5 + ($ 2,000,000 - $ 2,500,000)*.5 = $ 250,000 Prediction with Specialized Information System Low-Cost Signal, p = 0.8 High-Cost Signal, p = 0.2 High-Cost Signal, p = 0.8 Low-Cost Signal, p = 0.2
