Balassa-Samuelson Effect

The Balassa-Samuelson Effect is not an episode of The Big Bang Theory.

In 1964, these two guys, Balassa and Samuelson, independently observed that, when other countries want the stuff that an emerging economy exports (tradable goods), increased wages in that sector will spill over to the service sector of that economy.

A strong tradable goods sector supports like a strong bra, the wages of not only the tradeable goods sector, but also of the service sector of the economy as well. Win-win.
