Abstract

This paper examines the efficiency and distribution in perfect competition markets through the lens of the Marginal Productivity Theory. It begins by outlining the theoretical framework of perfect competition and the foundational principles of the Marginal Productivity Theory. The study then highlighting the role of marginal productivity in determining factor rewards and overall market outcomes. The paper further applies the theory to derive key formulas and provides a detailed analysis of their implications. Empirical evidence and case studies are used to validate the theoretical findings. The paper also includes a comprehensive section on the visualization of market dynamics, presenting five key graphs that illustrate the core concepts discussed. Finally, the paper discusses the practical challenges to perfect competition and the implications of market failures on efficiency and distribution.
