1. Suppose that the hourly wage W has a gamma distribution. Suppose that the mean value E (W ) of this variable is 20 USD per hour and the standard deviation σ(W) is 5 USD. Recall that for gamma distribution W ∼ Gamma(α, λ) E(W) = α/λ, Var(W) = α/λ2 Suppose that in the setting of the two envelope problem the job offer is applied not to annual salaries, but to hourly wages. The open envelope has an offer of...
