This document discusses key concepts of a free market economy including supply and demand, economic equilibrium, and spontaneous order. It analyzes how a free market allocates resources efficiently through market forces and price mechanisms without government intervention. The document also addresses three basic economic decisions that every society must make: what goods and services to produce and in what quantities, how to produce them, and who gets them. It explains how Nigeria answers these questions, with both government and private sectors determining production and market forces allocating based on demand. Natural resources like petroleum influence Nigeria's economy, with production, agriculture, and informal sector accounting for most economic activity.
