Abstract

Purpose: This study aims to examine the consumption behaviour in Organization of Islamic Cooperation countries. Design/methodology/approach: Using time series and panel data, this study estimates rational expectations permanent income hypothesis model and the intertemporal elasticity of substitution, and examines the response in consumption to expected and unexpected changes in income. Findings: The evidence supports the phenomenon of loss aversion. The response of consumption to unexpected income changes is statistically significant in only one-third of the countries in the sample. Conversely, the response of consumption to expected income changes is statistically as well as economically significant in one-fourth of the countries in the sample. The intertemporal elasticity of substitution is also statistically insignificant in majority of OIC countries in the sample. Practical implications: The evidence in support of loss aversion in preferences could help in explaining the low penetration of equity-based risk sharing instruments in Islamic finance. Social implications: The excess sensitivity of consumption to income suggests that redistribution efforts to enhance incomes of poor households could help in enhancing their consumption levels. Originality/value: The study takes a comprehensive sample across time and space for OIC countries as compared to previous studies and also adjusts the budget constraint for Zakat.
