25 Mar 2019  Modeling Scenarios  Contributor(s): Lyle Clifford Smith
This scenario models the loss of employees and the employer's attempt to retain them through stock options. It most naturally is solved with a firstorder linear decay model with two populations. This is intended for introductory students and is paired well with exponential growth/decay...
