Short Run

- In microeconomics, a period of time in which producers are able to change the quantities of some but not all of the resources they employ; a period in which some resources (usually plant) are fixed and some are variable. - In macroeconomics, a period in which nominal wages and other input prices do not change in response to a change in the price level.
