Concentration Ratio Pyramid - Lesson Activity

Jonny Clark

12th August 2015

Here's a classroom activity on concentration ratios for those of you planning your lessons for your A2 business economics classes.

The activity can be used as an investigation into the competitiveness of 10 UK oligopolistic markets (e.g. newspapers, car manufacturers) or taken further if you wished to use it for making 3-firm concentration ratio calculations (that may occur in AQA exam papers, for example) or even if you wanted to compare the concentration ratio for a market against the Herfindahl–Hirschman Index (HHI) for that same market.
