Discussion of A Dynamic Structural Model of Sales Force Response to Compensation Plans Ram Rao
Research Goals • Analyze effect of compensation plan on performance • Dynamic Structural Model • Invoke new estimation methodologies • Obtain more “reliable” estimates • Can quotas help? • Quarterly quotas, like “pacers” • And how about “overachievement” commissions?
Practical Issues • Risk Aversion • Salary needed, pure commissions won’t work • Sales need to be coordinated with production etc. • Need to forecast • Salespersons are not all similar • Heterogeneity
What does theory have to say? • Risk Aversion • Commission rates must be increasing in output • Forecast • Salespersons must share information and work with (self-imposed) targets (quotas) • Heterogeneity • Quotas must vary across salespersons
Theory vs. Practice “Overachievement” commissions Optimal non-linear plan Authors’ plan F Bonus SALESPERSON EARNINGS Commissions Salary SALES
What is being estimated?And how? • Sales response • Think of them as sensitivity to exogenous variables AND state variables, primarily how near salesperson is to quota • EM with latent class • Salesperson disutility for effort • Simulation, assuming salespersons are optimizers
What do we learn from counterfactuals (pure commission)? • Current plan is best! 23%, 15% • Removing overachievement commissions naturally makes exceeding quota to be undesirable, educing early period effort to control likelihood of exceeding. Revenues and profits 5% • Quarterly quotas AND bonus keep performance high 23%
My take • Why might quarterly bonuses work? • If salesperson is risk averse they might prefer a more certain outcome with small payoff • My rough calculation tells me Pr (miss all three quarterly bonus) =1/8 Pr (miss annual bonus) =1/2 The two events are not independent, but my point may be right
Behavioral Stuff • May be salespersons need pacers • Students do • Measurements and feedback are known to improve performance in many fields • Ratcheting is problematic • Is there no room for negotiations between salesperson and manager? • You have to wonder why managers are paid more?
