Commentary on "Dynamic Incentives in Sales Force Compensation".

This paper points out the error in the HJB equation in a previous published paper and presents the correct HJB equation. We show that the Hamilton-Jacobi-Bellman (HJB) equation for the salesperson's problem is not correct because of the effect of a positive discount factor for the infinite-horizon risk-sensitive control. As a result, their analyses and insights are incorrect. We present the correct HJB equation for the salesperson's problem, which is a partial differential equation. Thus, further investigation on the correct solutions is needed to better understand the problem. History: K. Sudhir served as the senior editor for this article. Funding: X.
