السلوك غير المتماثل للتكاليف وانعكاسه على ربحية الشركات الصناعية اليمنية في ظل الأزمة الاقتصادية "دراسة تطبيقية"

Abstract

This research aims to provide further empirical evidence on the asymmetric behavior of costs in Yemeni industrial companies and to measure the impact of such behavior on the profitability of these companies under the prevailing economic crisis.

To achieve this objective, an applied study was conducted using data from 14 Yemeni industrial companies, with a total of 86 observations covering the period from 2011 to 2017. The research employed multiple linear regression models using panel data with fixed effects to test the hypotheses. The findings indicate that operating costs exhibit asymmetric behavior—being upward sticky prior to the economic crisis and downward sticky during the crisis period. Moreover, the stickiness of operating costs has a negative effect on both Return on Assets (ROA) and Net Profit Margin (NPM) before the crisis, while it has a positive effect during the crisis in Yemeni industrial companies.
