The Open Markets Institute Report on "America's Concentration Crisis" (https://concentrationcrisis.openmarketsinstitute.org/) presents a collection of markets where concentration is very high (based on the dominant firms' market shares).

Based on what you learned about monopoly power and its determinants, select two markets from the report; one should be a market in which concentration is likely to lead to more consumer harm (higher prices, lower consumer surplus) and one a market which leads to less consumer harm.

You must refer to the economic factors that lead to monopoly power and stay away from ethical or moral considerations.

Make sure to pick two markets that make the contrast between higher and lower consumer harm very clear. Explain.
