On-Demand Delivery Platforms and Restaurant Sales

Management Science · 2024

For your marketing

Use it as a B2B mechanism or sales-process design reference. Validate the relationship in your deal size, buying committee and sales cycle.

Plain-English take

Restaurants overall benefit: delivery platforms increase total takeout sales and create positive spillovers to dine-in visits. Effects are heterogeneous: the overall positive effect for fast-food chains is four times that for independent restaurants; platforms substitute for independent restaurants' own takeout but complement chain takeout, while increasing dine-in visits for both. The paper also reports evidence that platform price comparison intensifies competition and reduces independent restaurants' ability to differentiate through premium service/dine-in experience.

Self-Selected Sales Incentives: Evidence of their Effectiveness, Persistence, Durability, and Underlying Mechanisms

Journal of Marketing · 2018

For your marketing

A founder could cautiously pilot employee-selected quota/reward menus in a randomized or phased rollout, tracking revenue quality and retention as well as bookings. Do not assume the observed effects transfer across roles or that self-selection is always superior to a well-designed fixed plan.

Plain-English take

Compared with equivalent quota systems, allowing employees to select a goal–reward combination increased sales performance substantially. Effects were larger for employees with highly variable past performance and lower past performance; effects persisted when the scheme was discontinued and were durable when offered again. For a SaaS founder: A founder could cautiously pilot employee-selected quota/reward menus in a randomized or phased rollout, tracking revenue quality and retention as well as bookings. Do not assume the observed effects transfer across roles or that self-selection is always superior to a well-designed fixed plan.
