Identify the four basic market structures

Although there are many different examples of economies in the world, all of them demonstrate one or more of the four basic types of market structure. For this assignment, in your own words,

• Identify the four basic market structures, in order, from the best for consumers to the being the best for producers.
• Describe each in terms of their distinguishing characteristics (e.g., monopolies have only one producer). Make certain you describe how the characteristic distinguishes the associated market structure from other market structures.

It is okay to put your answers in a list rather than an essay format.
