I have three goods:
- carp (fish)
- museum ticket
Is it possible to tell anything about market structure if I have annual price data of the industries? Here's the time-series plot on a single graph: I would like to give advice whether a firm should entry the market or not. Is is it possible to decode price data like "the incumbent firms must have been playing a Bertrand's price competition game at the carp market"? Or do I need further details to say anything about the market structure?
Is it possible to apply IO theory if I have only price data of an industry? I really need some clues, please.
