This paper seeks to extend the literature on cost behavior by providing additional evidence on sticky cost behavior in developing countries namely Egypt. Moreover, it aims to determine to what extent sticky cost behavior affects earnings quality. The paper depends on a sample consists of 38 listed firms in the Egyptian Exchange over the period from 2004 to 2017. The findings reveal that total costs respond asymmetrically to the equivalent change in sales in six of the nine examined sectors. Furthermore, both patterns of sticky cost behavior, stickiness and anti-stickiness, negatively affect earnings quality. Therefore, managers, investors, and managerial accountants should take into account sticky cost behavior when making their decisions. This study contributes to the stream of research that integrates managerial accounting with financial accounting by combining sticky cost behavior with earnings quality. In addition, it extends the line of research related to the impacts of sticky cost behavior. Moreover, it gives new evidence on sticky cost behavior and its impacts from one of emerging countries.

The major objective of this study is to explore the moderating role of credit risk and liquidity risk on business diversification and banks' performance relationship, i.e., investigating the interaction relationship between banks' risks and business diversification on banks' performance. In light of this, the study also aims to examine the impact of credit risk and liquidity risk on banks' performance, especially in emerging countries like Egypt. Moreover, it seeks to test the effect of business diversification, through revenue diversification, asset diversification, and funding diversification, on banks' performance. This study depends on a sample consisting of 10 banks over the period from 2012 to 2021. The findings indicate that credit risk has a negative impact on banks' performance, whereas liquidity risk has a positive impact on banks' performance. Also, revenue diversification and asset diversification have a positive effect on credit risk, and only asset diversification has a positive effect on liquidity risk. Furthermore, all activities of diversification have an insignificant impact on banks' performance. The most important result is that credit risk and liquidity risk moderate business diversification and banks' performance relationship as credit risk changes the effect from an insignificant negative impact to a significant positive effect. Also, credit risk adjusts the impact of asset diversification from an insignificant positive impact on banks' performance to a significant positive impact. Furthermore, liquidity risk is able to convert the impact of revenue diversification on banks' performance from an insignificant negative impact to a significant negative impact.
