Background
Horizontal equity is a principle of fairness in economics, which posits that individuals in similar circumstances ought to be treated identically. This principle is crucial when addressing just distribution and equity within various economic frameworks.
Historical Context
The concept of horizontal equity emerged as economists and policymakers sought equitable strategies within the tax system and resource allocation. It serves as a response to injustices stemming from arbitrary differences in treatment among like individuals.
Definitions and Concepts
Horizontal Equity: The principle that two individuals in the same or similar conditions should be treated equally, particularly concerning taxation and socioeconomic policies.
Vertical Equity: This differs from horizontal equity as it focuses on considerations about redistributing wealth to address income disparities.
Major Analytical Frameworks
Classical Economics
Classical economists emphasized efficient markets and minimal state intervention. Horizontal equity was not directly discussed but was implicit in the advocacy for equal treatment within free markets.
Neoclassical Economics
Neoclassical economics recognizes horizontal equity concerning utility maximization and fairness, suggesting equal treatment promotes an efficient allocation of resources.
Keynesian Economics
Keynesians might invoke horizontal equity in advocating for fair and just distribution of resources to promote consumption and investment stability.
Marxian Economics
Although primarily concerned with vertical equity and class struggles, Marxian theory acknowledges horizontal equity within the working class as everyone should face equal treatment regardless of their industrial role.
Institutional Economics
This branch examines how rules and organizations impact economic outcomes, including adherence to horizontal equity principles in institutions to foster trust and fairness.
Behavioral Economics
Behavioral economists investigate how fairness, including horizontal equity, affects decision-making and satisfaction within economic activities.
Post-Keynesian Economics
Post-Keynesians might emphasize horizontal equity in government policies aimed at stimulating aggregate demand through just wage and tax interventions.
Austrian Economics
Austrians, valuing individual choice and market solutions, would see horizontal equity as essential but rely more on spontaneous order within free markets to achieve it.
Development Economics
Horizontal equity is crucial in development policies, ensuring similarly positioned individuals receive equal opportunities and resources, fostering inclusive growth.
Monetarism
Monetarists may reference horizontal equity in fiscal policies to maintain economic stability by ensuring equitable taxation among like individuals.
Comparative Analysis
Horizontal equity views contrast and complement vertical equity. While horizontal equity stresses fair treatment among equals, vertical equity addresses the redistribution needed to bridge gaps between unequal positions.
Case Studies
Instances of implementing horizontal equity can be seen in tax reforms that ensure individuals in similar income brackets pay equivalent tax rates, thus promoting fairness and adherence to economic definitions of equity.
