Causes of changes in globalisation: changes in communication costs

International Trade and Globalisation – Globalisation and Trade Restrictions

1. What are Communication Costs?

Communication costs are the expenses involved in sending information between businesses and consumers across borders. Think of it like the price of sending a letter 📧 versus a quick phone call 📞. The cheaper and faster the communication, the easier it is for companies to coordinate with partners worldwide.

2. How Communication Costs Drive Globalisation

When communication costs drop, businesses can:

• Quickly share product designs and market data.
• Negotiate contracts in real‑time.
• Monitor supply chains from anywhere in the world.

This leads to more global supply chains and international trade.

3. The Cost‑Reduction Timeline (Analogy)

Imagine sending a parcel of goods. Initially, you had to pay a high fee for a courier and wait days for a reply. Over time, the courier fee fell, and you could use email instead of letters. The same happened with communication technology:

1. Pre‑Internet: High cost, slow communication.
2. Internet boom: Cost ↓, speed ↑.
3. Mobile & cloud: Cost ≈ zero, instant.

As the cost curve $C_t$ (communication cost at time $t$) falls, the trade volume $T$ tends to rise: $T \propto \frac{1}{C_t}$ (simplified relationship).

4. Trade Restrictions and Communication Costs

Governments may impose tariffs, quotas, or export bans to protect domestic industries. However, when communication costs are low, these restrictions become more visible and harder to hide. Businesses can quickly spot unfair barriers and respond with:

• Shifting production to other countries.
• Using digital platforms to bypass physical barriers.
• Lobbying for trade agreements.

5. Case Study: The Rise of E‑Commerce

E‑commerce giants like Amazon and Alibaba show how cheap communication (fast data transfer, low bandwidth costs) has enabled:

• Instant order placement worldwide.
• Real‑time inventory updates.
• Global customer support via chat.

These features would have been impossible when communication was expensive and slow.
