The financial system plays an essential role in facilitating the intermediation process for economic growth. Policymakers stress on achieving a well-developed and regulated financial system to achieve economic development and resiliency. Using data from the State of Qatar, this paper aims to examine the impact of financial development indicator on economic growth; the impact of financial development indicator on hydrocarbon and nonhydrocarbon sector; the impact of Islamic banking on hydrocarbon and nonhydrocarbon economic growth. The research uses quarterly data from 2007 to 2019 and adopts autoregressive distributed lag cointegration techniques to test the long- and short-run dynamic relationship between various measures of financial development and economic growth. The results present evidence of long-term cointegration between overall financial development indicator and economic growth. Furthermore, the authors document the existence of long-term relationship between financial development and nonhydrocarbon sector. However, there is a lack of evidence on the long run relationship between financial development and the hydrocarbon sector. Notwithstanding, Islamic banking contributes to overall economic development, as well as to the nonhydrocarbon sector. This paper offers policymakers with insights to evaluate measures to diversify the economy. It also assists decision-makers in promoting Islamic finance, particularly to the banking sector as a vital contributor to economic growth. To the best of the author's knowledge, this paper is the first to evaluate financial development and economic growth for the case of Qatar in light of recent developments in Islamic finance.

The issues of earning management has received attention from practitioners and academicians since the last couple of decades in banking sector. It is evident that bank managers practice the discretion in estimating loan/finance loss provisions for various motives such as reducing earnings variability (Agarwal, Chomsisengphet, Liu & Rhee, 2007; Kanagaretnam, 2004). Majority of the studies have been focusing on conventional banks, and only a few studies have focussed on Islamic banks, for instance, Zoubi and Al-Khazali (2007) and Othman and Mersni (2014). The significance of examining the issues in the context of Islamic banks stems from the fact that Islamic banks should not manage their earnings the way their conventional banks do. This is because the underlying theoretical basis of Islamic banks are based on Shariah principles which is different from conventional banks.

The paper investigates whether there is a significance difference between the practices of discretionary loan/finance loss provisions between Islamic and conventional banks. Same time, the paper tests whether the efficiency may influence the behaviour of discretionary loans/finance loss provisions, taken into consideration other micro and macro variables. The study utilizes panel data runs over 1996-2011 with unbalanced observations for 16 banks, of which 4 Islamic banks. In order to achieve research objectives, the two-stage approach is adopted to examine the factors that may influence the behaviour of discretionary loan/finance loss provisions with specific emphasize on the efficiency. Furthermore, efficiency scores are estimated using Data Envelopment Windows Analysis. The findings of the research show that Islamic banks employ the discretionary loans/finance loss provisions to manage their earnings. However, the magnitude of discretion of accruals is significantly lower than conventional banks with exception for foreign banks which have reported lower discretionary loans/finance loss provisions than Islamic banks. Moreover, the analysis showed that efficiency affects the overall discretionary loans/finance loss provision positively, although this impact is shaped differently for Islamic and conventional banks.
