What is Samuelson's core contribution to economic theory?
A central contribution was the formalization of microeconomic theory, particularly through the concept of revealed preference, which provided a robust axiomatic foundation for consumer theory without relying on unobservable utility. This approach allowed for clear, testable hypotheses about consumer behavior. My work also greatly advanced the understanding of general equilibrium and welfare economics, demonstrating how to analyze the efficiency of resource allocation in a comprehensive manner using mathematical tools.
