Agglomeration economies describe cost advantages that arise from clustering firms. Which of the following is a typical example?

• A. Cost advantages from clustering firms, such as shared services, supplier networks, and labor pools
• B. Increased long-distance transport costs
• C. Higher taxes
• D. Reduced innovation

Answer: (B)

Agglomeration economies come from firms concentrating in one area, which cuts costs through nearby shared services, dense networks of suppliers, and a large, skilled labor pool. Being close together makes it cheaper to access inputs, coordinate with suppliers, and hire workers with the right skills.

This is why the best example is the clustering of firms that leads to shared services, supplier networks, and labor pools. Being close to suppliers and customers also reduces transportation and search costs, reinforces quick communication, and lowers overall production costs.

The idea isn’t about higher transport costs, which would come from dispersion rather than clustering, nor about higher taxes or less innovation—those aren’t typical advantages driven by firms locating near one another.
