One of the primary assumptions in accounting industries is to expect an increase (decrease) in cost of production is proportion to increase (decrease) in sales revenue. However, there are some evidences that the cost of production does not decrease with the same trend as revenue decreases. This phenomenon is called sticky behavior since the cost of production in not reduced as the sales decreases especially in operating as well as administration department. In this paper, we present an empirical investigation to study sticky behavior on 70 selected firms from Tehran Stock Exchange over the period 2002-2011. The results indicate that sales and general administration cost (SGA) as well as the costs of sold goods strongly have sticky behaviors.
