INTRODUCTION

English translation pending.

CORE DEFINITION

Proposed by Thomas Friedman, the Golden Arches Theory holds that no two countries with McDonald's franchises had ever fought a war against each other, because economic integration made conflict too costly. Its core claim is not about fast food itself but about interdependence: countries embedded in shared supply chains and trade have more to lose from war than to gain. The theory was qualified and effectively falsified by later conflicts, including the Kosovo war and the Russia-Ukraine war, which showed that nationalist and territorial aims can override commercial ties.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Read interdependence: measure how much each side would lose if the relationship ended. - Bind the partner: build links that make defection more costly than continued cooperation. - Test the bond: ask whether ideology or territory could outweigh the economic stake.

Anchor fast decisions

Trade and shared supply chains make each side's prosperity depend on the other's cooperation. A war would destroy that value for both, so the expected cost of conflict rises above the expected gain, and the rational choice shifts toward settlement. The mechanism works only while the economic stake exceeds whatever is being fought over, which is why nationalist or territorial aims can still break the pattern.
