They also elevate their adopted and origin countries’ standings in global value chains, contributing to economic resilience.

We are economists who study global trade and migration, and our recent work reveals that immigrants contribute far more to the economic fabric of nations than previously understood.

By facilitating what’s known as “trade in value added,” or TiVA, immigrants play a crucial role in helping countries specialize their production, move up the value chain and significantly enhance trade sophistication.

Moving up the value chain means progressing from producing basic, low-value goods to more complex, higher-value products. This shift involves improving skills, technology and production techniques, allowing a country to capture more economic value and develop advanced industries.

So, what exactly is trade in value added, and why is it important?

TiVA measures each country’s contribution to a final product, providing clearer insight into global value chains. For instance, while an iPhone may be assembled in China, its components come from various countries, each adding value.

Our study found that a 10% increase in immigrants from a........
