Two Big Questions
- Good vs. Bad Concentration?
- Good concentration: low prices and productivity growth
- e.g, retail & wholesale trade
- returns to scale; intangible investment
- Bad concentration: high prices and low productivity
- e.g., telecoms, airlines, healthcare
- what are these barriers?
- Technology vs. Policy?
- Network effects vs regulation & antitrust
