## TL;DR

Economic systems are ways societies coordinate production, distribution, and consumption. Common high-level categories include traditional, command, market, and mixed systems.

## Core Explanation

A mixed economy combines market activity with government intervention. Keynesian economics is not itself a complete economic system; it is a macroeconomic theory associated with policy responses to employment and output fluctuations.

## Evidence Notes

The previous version compressed capitalism, socialism, GDP, inflation, Gini coefficient, Keynesian economics, neoliberalism, and China into broad claims backed by one textbook page. This repair narrows claims to directly sourced definitions.
