The Local Operations Manager for the IRS Must Decide Whether

Short Answer

The local operations manager for the IRS must decide whether to hire one, two, or three temporary workers. He estimates that net revenues will vary with how well taxpayers comply with the new tax code. $$\begin{array} { c c c c } \text { \# of Workers } & \begin{array} { c } \text { Low } \\\text { Compliance }\end{array} & \begin{array} { c } \text { Medium } \\\text { Compliance }\end{array} & \begin{array} { c } \text { High } \\\text { Compliance }\end{array} \\\hline 1 & 50 & 50 & 50 \\2 & 100 & 60 & 20 \\3 & 150 & 70 & - 10 \\\hline\end{array}$$
If he uses the minimax regret criterion, how many new workers will he hire?
