An efficient market structure requires a completely free market without interference of outside bodies (e.g. government). It requires a free and open flow of information. It requires sufficient quantities available for trade so that buyers and sellers can make trades easily and quickly. It requires that no single player or association of players can control pricing or availability.
There is no one perfect market to hold up as an example. All of the major worldwide markets (oil, wheat, pork, etc.) have government interference. Some, like oil, have oligopolies that control both production and distribution. None of the markets worldwide have completely free flow of information.
Possibly the most efficient capitalist market worldwide is that for coffee.
