Phase IFoundation

Background

Overview

UPSC emphasizes understanding the complexities of the globalized economy, including how integrated supply chains affect national economies, resilience to shocks, and the implications for trade policy and international cooperation.

Economic interdependence describes a relationship where countries rely on each other for goods, services, and resources, making their economies mutually sensitive to policy changes or disruptions in one another. Global supply chains are networks of organizations, people, activities, information, and resources involved in moving a product or service from supplier to customer across national borders.
