PurposeThe economic and financial literature dealing with the subject of bank profitability has often been based in the measurement of banking results on three main indicators: ROA, ROE and MIN. This article aims to determine and analyze the different determinants that influence bank profitability and to identify the impact of these determinants on the profitability of Moroccan banks.Design/methodology/approachFor this purpose, a fixed individual effect model was adopted for the case of six Moroccan banks during the period of study from 1997 to 2018. The authors carried out their estimates at three levels according to three categories of profitability factors: bank factors, factors of the banking system and macroeconomic factors.FindingsThe empirical findings show that Moroccan banks react on their size to boost their performance, which further explains the continued expansion of Moroccan banking networks. The authors confirm that Moroccan banks have not yet reached a level of size that will be detrimental to their performance. Therefore, the authors can conclude that the big Moroccan banks do not follow the concept of economy of scale. The effects of the variation in the level of economic growth as well as the evolution of the level of inflation on the performance of Moroccan banks are not significant.Originality/valueThe authors’ findings and results have some important originality and value. Primarily, these results would consist of better helping the State, bankers, and bank managers to better understand the various determinants of bank profitability. The results may also help to better examine the effect of each factor, whether internal or external, on banks' bottom line.

Business performance has attracted researchers' attention in the previous literature of corporate finance. However, in the framework of the life insurance sector, they have given a number of attentions. In our paper, we investigate empirically the effect of firm-specific characteristics (size, leverage, tangibility, risk, growth, liquidity and age) on the profitability of eight Tunisian insurance companies during the period of study from 2005 to 2015. The empirical results show that the variables size, age and growth are the most important determinants of the performance of Tunisian insurance companies as measured by Return on Asset ratio. Then, leverage, tangibility, liquidity and risk don't affect the performance of Tunisian insurance companies.

The main objective of our paper is to propose a novel approach in pricing Islamic financial assets in accordance to shariah, advocated by contemporary investment theories of Markowitz's Mean-Variance Analysis and CAPM. The shariah-compliant Capital Asset Pricing Model that we developed with a few changing's of the traditional Capital Asset Pricing Model is integrating zakat, purification of return and exclusion of short sales. Then, we utilize a sample composed of 10 shariah-compliant public listed companies in Bursa Malaysia. The empirical results find that the proposed Islamic CAPM is appropriate and applicable in investigating the linkage amongst risk and return in the Islamic stock market. Our investigation contributes to existing body of knowledge by presenting an algorithm and mathematical modelling of the shariah-compliant CAPM which has been lacking in the literature of Islamic finance.
