We hope this in-depth review will help them understand all market structures and how they affect government and how they operate. The market structure I will start with is perfect competition. In our text it is stated that perfect competition is “the market”. structure in which there are many sellers and buyers, firms produce a homogeneous product, and there is free entry and exit from the industry. Perfect competition is considered a theoretical model (Amacher and Pate 2013, chapter 9, section 1). In perfect competition, there is no market leader. There are six assumptions of perfect competition: "there are a large number of sellers, there are a large number of buyers, that perfectly competitive firms produce a homogeneous product, there is free entry and exit from the market, knowledge are perfect and workers and other resources can easily move in and out of the industry. (Amacher and Pate 2013, chapter 9, section 1.) There are many conditions in this type of market and for the perfect competition part, they are very strict. Middle of paper ......te, J. (2013).
