摘要翻译：
目的是通过衡量伊斯兰银行的完美随机回报(SR)模型和传统银行的固定回报(FR)模型在宏观经济层面的影响来比较它们。我们证明了如果SR模型中投资者份额的最优选择{alpha}*实现了金融机构对SR和FR模型的无差别，则存在{alpha}小于{alpha}*的情况，从而银行严格地偏好SR模型。同时，存在{alpha}、{gamma}和{lambda}验证了{alpha}共享的条件，使得在SR模型下，经济中的各方都能得到改善，经济福利能以帕累托有效的方式得到提高。

英文摘要：
  The purpose is to compare the perfect Stochastic Return (SR) model like Islamic banks to the Fixed Return (FR) model as in conventional banks by measuring up their impacts at the macroeconomic level. We prove that if the optimal choice of investor share in SR model {\alpha}* realizes the indifference of the financial institution toward SR and FR models, there exists {\alpha} less than {\alpha}* such that the banks strictly prefers the SR model. Also, there exists {\alpha}, {\gamma} and {\lambda} verifying the conditions of {\alpha}-sharing such that each party in economy can be better under the SR model and the economic welfare could be improved in a Pareto-efficient way.
