FTC conducted an empirical analysis on the determination of firm's profits and price changes. The explanatory variables using in this analysis are including the buyer concentration and the ranking/share fluctuation indices, which were newly calculated using FTC's data of market concentration and market share.
The main outcomes of this analysis were as follows:
i) the stronger the buyer, the lower the seller's profit
ii) the larger the fluctuation of firm's share, the lower the profit and price tended to decrease.
