Investment appraisal practices: A comparative study of conventional and Islamic financial institutions

This paper compares the use of capital budgeting techniques of conventional and Islamic financial institutions, using data obtained from a survey of 105 conventional and Islamic financial institutions. Our main aim is to analyze the use of capital budgeting and risk techniques by the two types of financial institutions from a comparative perspective to see whether prohibition of riba makes a difference. Standard difference-of-means tests of the mean scores methods were used to test the hypotheses of the study. The results reveal a number of important conclusions. First, discounted cash flow techniques are found to be more widely used by financial institutions, and among those techniques internal rate of return is the most common. Second, Islamic financial institutions are found to adopt traditional methods that do not comply with the principles of Islamic Sharia'a. Third, a huge gap is found between the theory base of Islamic institutions and some of the practices of those institutions. Fourth, firms' characteristics, such as size, listing status, sources of revenue and government ownership, have some impact on their decisions to adopt capital budgeting criteria, methods of estimating costs of capital and risk. Finally, the decisions to select particular capital budgeting techniques, cost of capital estimation methods, and risk assessments are partly related to the characteristics of the chief financial officers.
