How Mobile Phones Destroyed 60% of India's Boat Factories: Market Integration & Firm Growth
Market Integration, Demand and the Growth of Firm
Imagine a market where the best product sells for the same price as the worst. That was the reality for India's traditional boat-building industry before mobile phones arrived. This video breaks down a landmark study from Kerala, India, where the gradual rollout of mobile phone towers triggered an unexpected industrial revolution. We reveal how fishermen, once trapped in information silos, used phones to share real-world quality data—exposing which boats lasted 7.6 years versus just 3.3. The result? A brutal shakeout: 60% of low-quality workshops vanished, surviving firms doubled their output, and per-year boat costs dropped 23% for consumers. But not everyone won. We explore the hidden winners and losers, including how quality-adjusted prices actually rose for villagers near top builders. No dry economics—just the raw story of how a simple technology upgrade rewrote the rules of survival, growth, and inequality in a craft industry. By Robert T. Jensen and Nolan H. Miller, from their paper 'Market Integration, Demand and the Growth of Firm'.
