Partial Equilibrium

An analysis focusing on a specific part of the economy while ignoring the effects on the rest of the economy

Background

Partial equilibrium analysis is a method used in economics to study the equilibrium of a particular market or sector while disregarding the broader economy’s interdependencies. Only variables directly related to the market under consideration—such as price and quantity—are studied.

Historical Context

The concept of partial equilibrium can be traced back to the work of Alfred Marshall, a pioneer of neoclassical economics. Marshall introduced partial equilibrium as a pragmatic tool to simplify the more complex general equilibrium model proposed by Léon Walras.

Definitions and Concepts

Partial equilibrium pertains to the study of economic equilibrium in a single market, assuming that other markets remain constant. This means ignoring potential feedback effects or indirect consequences arising from changes in the market being studied.

Major Analytical Frameworks

Classical Economics

Classical economists place less emphasis on partial equilibrium, focusing more on the dynamics of the entire economic system.

Neoclassical Economics

Neoclassical economists, particularly influenced by Alfred Marshall, extensively use partial equilibrium to examine one part of the economy independently.

Keynesian Economics

Keynesians may use partial equilibrium analysis when examining individual markets, but generally prefer models that consider aggregate demand and supply.

Marxian Economics

Marxian economists rarely use partial equilibrium, given their focus on the entire economic structure and the relations between its parts.

Institutional Economics

Institutionalists might apply partial equilibrium analysis but emphasize the influence of institutions on economic outcomes over a broader scope.

Behavioral Economics

Behavioral economists can use partial equilibrium analysis to isolate specific market behaviors, though they often include psychological and cognitive factors in broader models.

Post-Keynesian Economics

Post-Keynesians typically argue for the use of general over partial equilibrium analysis due to the interconnected nature of economic markets.

Austrian Economics

Austrian economists critique partial equilibrium models for overlooking the dynamic process of market exchanges and time preferences.

Development Economics

In development economics, partial equilibrium methods may be used to study specific sectors, although broader economic impacts are generally of interest.

Monetarism

Monetarists, like Milton Friedman, may utilize partial equilibrium in focused monetary analysis but consider overall economic impacts essential for policy recommendations.

Comparative Analysis

Partial equilibrium analysis is efficient for examining specific markets when inter-market dependencies aren’t significant. However, for a comprehensive understanding of economy-wide effects, general equilibrium analysis is preferred.
