"When economists want to measure the competitiveness of an industry, they usually start by counting the number of competing firms. If they see a lot of firms, they infer a lot of competition. Few firms? Little competition. One firm? No competition at all. Three decades ago, a model came along to challenge this mindset: the contestable market model." (03/06/12)
