This unique study examines the moderation effect of institutional quality (IQ) on the relationship between financial inclusion (FI) and financial development (FD) of 45 Organization of Islamic Cooperation (OIC) countries. For empirical analysis, panel data are used for the period 2000–2016. We use the Arellano–Bond generalized method of moments (GMM) and two-stage least-squares (2SLS) method in our estimations to draw multidimensional results. The empirical results confirm the significant positive relationship between FI, IQ and FD. Interestingly, we find that IQ moderates FI and has a significant positive impact on FD. Our findings are robust to alternative econometric specifications of FI, IQ and FD. Therefore, policymakers must sensibly understand the pivotal role of FI and IQ in establishing sustainable future development of OIC countries.

This paper investigates physico-mechanical and petrographic attributes of Paleocene Lockhart Limestone which is measured, sampled and described from Rumli (RUM) and Shah Allah Ditta (SAD) sections of Islamabad. Petrographic analysis delineates that the limestone is categorized mainly into mudstone and wackestone microfacies and dominant presence of the micrite matrix favors the strength of the rock, whereas; veins, microfractures and porosities adversely affect the stability of the rock. Based on the UCS and PLT analyses, limestone samples incorporating the lowest porosities partnered with bioclasts encompass the highest UCS and PLT values and vice versa. The physico-mechanical analyses reveal that the limestone aggregates are within limits of the respective standards (ASTM, AASHTO, BS and NHA) for utilization in wearing, coating, cement concrete. The limestone of both sections can be utilized for geotechnical purposes like crushed material and aggregate source. Simple regression analysis was employed and based on these correlations; the limestone of the studied formation is designated as moderately strong and recommended for road or bridge construction purposes.
