Assume the effect size of the HRD program in the same year d+= 0.40 Assume that 200 employee are trained each year for 4 years, and that for each cohort, the training effect dissipates gradually at the rate of 20% annually. No employees separate during this period. Assume SDy=$25,000, Variable Costs (V) = -0.10, the tax rate is 35%, and the discount rate is 10%. 200 employees are trained per year at a cost of $1,200 per person. 1. Compute the weighted average d values each year for 4 years. 2. Compute the expected payoff for the 4 years in total.
