What is allocative and productive efficiency?

Allocative and productive efficiencies are theoretical concepts in economics. Allocative efficiency is achieved in an economy when the distribution or apportionment of resources produces the greatest utility for consumers through its combination of products. For example, and for the sake of simplicity, envision an economy with two products: pizza and robots. In an allocatively-efficient economy, businesses are producing the right amount of each product to make consumers happy. Productive efficiency, on the other hand, is when an economy is using all of its resources efficiently, producing the greatest output for the smallest input. Productive efficiency, on a production possibility frontier, occurs on any points along the curve.
