LONG RUN

A period in which all components of production and costs are adjustable. Companies are capable to adjust all costs, unlike in short run because it can only affect prices through adjustments made in production levels. In addition to that, companies can be a monopoly in the short-term for they may anticipate competition in the long run.

In economics, long run models can turn away from short-turn equilibriums, by which supply and demand respond to price levels with more flexibility.
