Do Islamic banks shift from mark-up to equity financing when their contracting environments are improved?

Islamic banks should share their profits and losses with their customers through equity financing but most of their assets are mark-up financing, which resembles loans. Theoretically, one of the reasons is Islamic banks operate in poor contracting environments where equity financing is very risky. Using fixed-effects models, we examine whether better contracting environments induce Islamic banks to shift from mark-up to equity financing. We find no evidence that contracting environments do, which means debt-like instruments will continue dominating Islamic banks’ assets in the near future.
