contestable market

a MARKET where new entrants face costs similar to those of established firms and where, on leaving, firms are able to recoup their capital costs, less depreciation. Consequently, it is not possible for established firms to earn ABOVE NORMAL PROFIT as this will be eroded by the entry of new firms, or, alternatively, the mere threat of such new entry may be sufficient to ensure that established firms set prices that yield them only a NORMAL PROFIT return. Perfectly competitive markets (see PERFECT COMPETITION) are all contestable, but even some oligopolistic markets (see OLIGOPOLY) may be contestable if entry and exit are easily affected.

In recent times many markets have been opened up by a number of developments, including increasing international competition as trade barriers have been reduced, the introduction of FLEXIBLE MANUFACTURING SYSTEMS and ECOMMERCE trading on the INTERNET. See WORKABLE COMPETITION, CONDITION OF ENTRY, BARRIERS TO ENTRY, BARRIERS TO EXIT.

A contestable market is one in which entry is completely free and exit is absolutely costless.
Thus, policy makers have simplified contestability, portraying the removal of barriers to entry as sufficient to create a contestable market. Through applying contestability theory in this manner, policy makers rely upon the robustness of a small group of studies (Baumol, 1982; Baumol et al., 1983; Baumol and Willig, 1981) that do not clearly support the applicability of contestability theory to real world markets.
Thus, the monopolistic firm behaves exactly as in a contestable market: Although it enjoys 100% of the market share, it does not have any market power.

The passenger airlift industry (further in the text PAI) is supposed to be contestable (quasi-competitive) in both the US and Western Europe, therefore it is often analyzed as a contestable market.
