The Effects of Traditional and Social Earned Media on Sales: A Study of a Microlending Marketplace

Journal of Marketing Research · 2012

For your marketing

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

Growing platforms within platforms: How platforms manage the adoption of complementor products in the presence of network effects?

Strategic Management Journal · 2023

For your marketing

Use it as a product, platform or behavior mechanism reference rather than a direct forecast for a SaaS funnel.

Plain-English take

Apps with direct network effects are more likely to receive an award. The likelihood rises with developer market share but falls in concentrated segments; in concentrated segments, challenger developers are more likely than leaders to receive the award.

Competing on freemium: Digital competition with network effects

Strategic Management Journal · 2022

For your marketing

Use this as a pricing or packaging hypothesis and define outcomes to measure; estimate effects with your own customer mix and willingness-to-pay evidence.

Plain-English take

Stronger network effects alone did not increase market leaders' revenues relative to followers. Where freemium was used, however, network effects greatly amplified leaders' advantage; the publisher describes this as increased revenue/market dominance for leaders only under freemium.

Openness in platform ecosystems: Innovation strategies for complementary products

Research Policy · 2021

For your marketing

Use it as a product, platform or behavior mechanism reference rather than a direct forecast for a SaaS funnel.

Plain-English take

Performance outcomes differ across co-existing innovation strategies. The publisher reports that platform sponsors have an active role in complementary products and that outbound and inbound collaboration may lead to high performance; appropriate strategy depends on platform lifecycle rather than a simple open/closed or sponsor/third-party choice.

Strategic Entrepreneurship Journal · 2025

For your marketing

Use it as a product, platform or behavior mechanism reference rather than a direct forecast for a SaaS funnel.

Plain-English take

Craigslist entry increases local entrepreneurial activity, especially in low-income regions; lower-income, Black, and immigrant individuals are more likely to create ventures afterward. Post-entry firms are smaller and mainly B2C rather than B2B.

How Users Drive Value in Two-Sided Markets: Platform Designs That Matter

MIS Quarterly · 2024

For your marketing

Use it as a product, platform or behavior mechanism reference rather than a direct forecast for a SaaS funnel.

Plain-English take

Cross-period same-side network effects contribute to user stickiness, while within-period cross-side effects persist conditional on stickiness. Using Groupon data, the authors verify the model and identify platform-design choices that can enhance stickiness when cross-period same-side effects are weak.

Stimulating Feedback Contributions Using Digital Nudges: A Field Experiment in a Real-Time Mobile Feedback Platform

MIS Quarterly · 2026

For your marketing

Use it as a product, platform or behavior mechanism reference rather than a direct forecast for a SaaS funnel.

Plain-English take

Task-significance messaging generated more and higher-quality feedback than generic prompts. Timing amplified the effect only when task-significance messaging was present; the follow-up experiment linked timing to lower cognitive load and task significance to greater germane load and external motivation, with effects varying by role.

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.

Value creation in data-centric B2B platforms: A model based on multiple case studies

Industrial Marketing Management · 2024

For your marketing

Treat this as evidence for the specific b2b growth and sales question studied. Compare the setting and sample to your company before changing a growth decision; use a local experiment where the paper does not match your context.

Plain-English take

Clients, providers, and enablers relate through data acquisition and manipulation. Governance mechanisms and boundary resources (including APIs, SDKs, connectivity devices, interfaces, rulesets and data-sharing agreements) support transactions, complementary applications, data-driven matching/network effects, new data-enabled business models, and faster/better decisions. The model distinguishes transactional and innovation behaviors and mechanisms of value creation. For a founder, use this as a question to test in your own context, not a universal playbook.
