Document Summary

Lecture slides that go with these notes are already posted on blackboard by the professor. Perfect competition (a benchmark case: no one firm can control the price; price takers, example: marijuana market. Government states that it will arrest some marijuana suppliers. This decreases supply, thus increasing the price and decreasing the quantity. This also decreases marginal cost (since supply comes from individual firms), thus decreasing quantity as well: why perfect competition matters in difference situations. In the short run, when some firms are making money (profit), there are another group of firms who would consider entering the market to get some profit as well. As a result, supply increases, thus decreasing price and increasing quantity. At some point, the supply curve will continue increasing until no firms are making any money (zero profit) and this will be the long run equilibrium where all firms are breaking even.
