Competition Concentration
Back to Competition
Topic Concentration

Concentration refers to two similar but distinct issues—the size of firms relative to the economy as a whole and the size of firms relative to their competitors. Equitable Growth is interested in both aspects, with an eye to how much concentration is occurring, its direct effects on prices and wages, and its indirect effects on innovation, entrepreneurship, and inequality.
