Network effects (aka network externalities, Metcalfe's Law, demand side economies of scale)
When the value of a product or service increases as its number of users expands.

Practice Quiz

1. A new meal delivery startup wants to enter the highly competitive Austin market. To convince students to switch away from established delivery apps, the startup offers the first five meals completely free of delivery and service charges. The company loses a significant amount of money on these initial orders, but they hope to build a massive user base that will eventually generate profits. Which strategy is the startup utilizing to build its user base?
Answer: B ~ Subsidizing adoption is a strategy to increase network size by offering price reductions, rebates, or giveaways to attract new users, often taking an initial loss. Freemium provides a basic service for free indefinitely while charging for premium features, rather than taking a loss on the core product to spark a network. Backward compatibility relates to supporting older technology. Platform envelopment involves absorbing a competitor's features.
2. A new campus ticketing application connects student organizations hosting events with regular students looking for weekend activities. As more clubs post their parties and fundraisers on the app, more regular students download it. Consequently, the massive influx of student users convinces even more clubs to abandon other platforms and list their events exclusively on this new app. Which specific concept best describes the dynamic between the student users and the club organizers?
Answer: B ~ Cross-side exchange benefits occur in two-sided markets when an increase in the number of users on one side (students) creates a rise in value for the other distinct side (clubs), and vice versa. Same-side exchange benefits involve value derived from peers in the exact same group (like students messaging other students). Technological leapfrogging involves releasing vastly superior technology to beat an incumbent. Platform envelopment is when a firm absorbs a competitor's features.
3. Three massive meal-kit delivery companies aggressively fight over young professionals in downtown Austin, constantly slashing prices and running expensive television ads against each other. A smart entrepreneur completely ignores this chaotic fight. Instead, she creates a unique microwave-only meal-kit service specifically designed for, and delivered exclusively to, college dormitories, facing absolutely zero competition. Which strategic concept does the entrepreneur's dorm-focused service best represent?
Answer: B ~ A blue ocean strategy involves creating and competing in completely uncontested, untouched market spaces (the dorms), rather than fighting in highly competitive, blood-red waters against established rivals. The freemium model gives away a basic tier for free. Platform envelopment involves absorbing a competitor's features into your own app. Technological leapfrogging means beating rivals by creating overwhelmingly superior core technology.
4. A fitness app allows anyone to download the program and track their daily steps for completely zero cost. However, if a user wants to access personalized workout plans and dietary coaching, they must pay a $10 monthly subscription fee. What pricing strategy is the app using?
Answer: D ~ The freemium model provides basic features or services for free, while charging a premium for advanced or additional features.
5. A major video game manufacturer is about to release a highly advanced, next-generation console. They know students are hesitant to spend $500 on new hardware if it means abandoning their expensive library of older games. To solve this, the manufacturer designs the new console so it seamlessly plays all the physical game discs purchased for the previous generation. Which strategy is the manufacturer using to ease the transition for buyers?
Answer: D ~ Backward compatibility is the intentional design choice allowing a new system to take advantage of complementary products (like old game discs) developed for a prior generation of technology. Platform envelopment involves absorbing competitor features. Freemium pricing gives away a base product for free. Complementary benefits are the third-party add-ons themselves, but making the system run old ones specifically is backward compatibility.
