“…Every 1% increase in net sales will increase SG&A costs by 1,077, whereas every 1% decrease in net sales will decrease SG&A costs by (1,077-1,484) -0.407%. Thus, it can be concluded that hypothesis one is accepted because the percentage increase is greater than the percentage decrease, or in other words, SG&A costs for consumer industry sector companies listed on the IDX in 2016-2018 are sticky, along with research conducted by Martania [3], Xue and Hong [6] and Wahyuningtyas and Nugrahanti [12] indication of stickiness cost behavior at SG&A costs. Based on table 2, the value of the coefficient of β1, β2 and β3 coefficient determine the truth of the hypothesis of the two proposed in this study.…”
