Real-World Examples of Positive Production Externalities

📚 Quick Study Guide

• 🌱 A positive production externality occurs when a firm's production benefits a third party.
• 🐝 These benefits are *external* to the firm's private costs and revenues.
• 🧪 Examples include: a honey farm benefiting a nearby orchard, research and development spreading knowledge, and employee training improving the local workforce.
• 📐 Graphically, positive production externalities imply that the social marginal cost (SMC) is less than the private marginal cost (PMC). This means that without intervention, the market will under-produce the good or service.
• 💰 Governments can incentivize production through subsidies to correct the market failure.
