Berlin Unpacks ‘Über Drei Ecken’: The Hidden Math of Diaspora Power

In the bustling policy corridors of Berlin, a distinctly German phrase is quietly reshaping how economists view global migration. “Über drei Ecken,” literally “around three corners,” has become the unofficial motto for diaspora economics—and it is sparking a new wave of political debate in Australia.

At its core, the term describes the indirect yet powerful ripple effects of migrant communities. Instead of a direct investment from a diaspora member to their home country, the money—or influence—travels a circuitous path. A Berlin-based startup founder, for example, might connect a supplier in Kenya with a buyer in Munich, all while their own family network in Australia benefits from the ensuing trade. That, in a nutshell, is the “über drei Ecken” effect.

For BERLIN, Australia’s politics desk, this concept is no longer just a cultural quirk. It is a strategic asset. The Australian government has long courted the skilled German diaspora, but recent analysis suggests they have been looking through the wrong lens. The real value isn’t in the taxes paid by the one German engineer living in Sydney, but in the three Australian businesses he connects to his old Berlin network over a single month.

Critics argue this tangled web is impossible to quantify, leaving tax collectors and trade negotiators in the dark. Proponents, however, see it as the future of soft power. Canberra must stop treating diaspora communities as isolated expat bubbles and start viewing them as three-cornered economic nodes.

As global competition for talent intensifies, the message from Berlin is clear: the most valuable citizens are not always the ones standing right in front of you. They are the ones standing two or three corners away, quietly moving the world’s economy around a table.
