Social interactions among consumers influence markets by spreading information about product quality. As consumers share information, demand changes, impacting prices and quantities produced by companies. Market prices eventually reach a certain level, but this can happen in different ways depending on the size difference between countries. If countries are very different in size, monopoly prices may persist for a while before transitioning to duopoly prices. This delay in price reduction may affect the benefits of globalization. Understanding how social interactions shape market outcomes is crucial for international economic integration.
