Özet:

Studies on cost behavior have shown that the increase in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs and the decrease in costs. This situation, called cost adhesion in literature, shows the opposite of the thesis "coins react equally to the increase and decrease of activity" which is supported by the traditional cost approach. In this study, it was also tested whether the annual data of 116 manufacturing companies operating in Borsa Istanbul for the period 2008-2016 showed cost adhesive behavior. For this purpose; sales and sales costs, sales and marketing sales and distribution costs and sales and general management costs were established three different models and tested with panel data analysis. As a result of the analyses made, the existence of cost adhesive according to both three models was identified. This supports the previous work.
