Why Information Grows

**Author:** César A. Hidalgo **Estimated Reading Time:** 45 minutes

Why some economies create extraordinary products while others remain trapped in simplicity. How information emerges from the physical world and becomes the foundation of prosperity. What separates societies that accumulate knowledge from those that cannot. How products act as vessels for collective human imagination.

Readers who want to understand the deep connection between physics, information, and economic development. Anyone curious about why certain regions innovate while others stagnate. Those seeking a framework for understanding how knowledge becomes tangible and how economies grow.

Every economy on Earth faces the same fundamental question: why do some places produce airplanes, pharmaceuticals, and microprocessors while others produce only raw materials and simple goods? The conventional answers point to capital, institutions, geography, or education. But César Hidalgo, a physicist who turned his attention to economics, saw something deeper at work. The answer, he argues, lies in information. Not information in the abstract sense of bits and bytes floating through cyberspace. Information as a physical property of the universe. Information as order. Information as the arrangement of atoms, molecules, and materials into patterns that matter. Consider a simple observation. A Bugatti Veyron costs more than a Toyota Corolla. Both are cars. Both have engines, wheels, and seats. Both get you from one place to another. The difference in price is not explained by the weight of the materials, since the Bugatti is not made of gold. It is not explained by the labor hours, since both are manufactured in factories. The difference lies in the arrangement of the materials. The Bugatti embodies more information. Its parts are arranged in a more complex, more precise, more difficult-to-achieve configuration. This observation opens a door to a completely different way of understanding economic development. Hidalgo's central insight is that economic growth is not fundamentally about accumulating more stuff. It is about accumulating more information. A society becomes wealthy not when it has more resources, but when it has more knowledge embodied in its people, its networks, and its products. The problem is that information is difficult to accumulate. It decays. It resists transfer. It requires specific conditions to grow. Understanding these conditions is the key to understanding why some economies flourish and others flounder. The traditional economic view treats knowledge as something that exists in books and patents, freely available to anyone who wants it. But Hidalgo points out that this view misses something crucial. Most knowledge is not written down. It exists in the minds of individuals, in the relationships between people, and in the physical structure of products themselves. This knowledge, which Hidalgo calls knowhow, is sticky. It does not flow easily across borders or between organizations. The…
