Sethi is known for his accomplishments in unifying many theories and concepts in Sethi model, Sethi-Skiba point, K-convexity in Rn Decision and Forecast Horizons, and Supply Chain Coordination with Risk Averse Agents.

#### Sethi model

The Sethi model describes the process of how sales evolve over time in response to advertising. The model assumes that the rate of change in sales depend on three effects: response to advertising that acts positively on the unsold portion of the market, the loss due to forgetting or possibly due to competitive factors that act negatively on the sold portion of the market, and a random effect that can go either way. The following are related journal publications over the years that established and generalized Sethi model.

#### Sethi-Skiba point

Sethi-Skiba points arise in optimal control problems that exhibit multiple optimal solutions. A Sethi-Skiba point is an indifference point in an optimal control problem such that starting from such a point, the problem has more than one different optimal solutions.
