Market Failure and Environmental Externalities

1.1 Market Failure & Externalities

Environmental pollution constitutes a classic negative externality where private market transactions impose uncompensated costs on third parties, leading to social overproduction.

Marginal Social Cost Equation:
$$MSC = MPC + MEC$$

Where: $MSC = \text{Marginal Social Cost}$, $MPC = \text{Marginal Private Cost}$, $MEC = \text{Marginal External Cost}$.

1.2 Coase Theorem & Environmental Kuznets Curve (EKC)

Coase Theorem Statement

"If property rights are well-defined and transaction costs are zero, private bargaining will lead to an efficient outcome regardless of the initial allocation of property rights."

Environmental Kuznets Curve (EKC):

The EKC hypothesizes an inverted U-shaped relationship between per capita GDP and environmental degradation. As economic growth proceeds, pollution initially increases, reaches a peak, and subsequently declines due to technological efficiency and environmental demand.
