Professor Fujioka analyzed the optimization behavior of consumers in a Deposit-Refund System in his paper which he published in <i>Studies in Regional Science</i>, vol. 29 No.3, 1998. Professor Oishi criticized Professor Fujioka's two stage maximization analysis as the strange case of Dr. Jekyll and Mr. Hyde in his paper which he published in <i>Studies in Regional Science</i>, vol. 32 No.1, 2002. Alternatively, he proposed a well-refined model of a unified Deposit-Refund Theory.<br>In this paper, first we provide a new model for the Deposit-Refund System Analysis. Second we conclude the new model is a specified one of the Oishi model because the two stage maximization of a representative consumer in the new one is consistent with the one stage maximization of the Oishi model <i>with strict assumptions</i>. Thirdly we conclude the Fujioka's is also a specified kind of the Oishi model because the Fujioka model should be identified as the new one from my point of view. Finally, we note that the two stage maximization <i>without strict assumptions</i> in the new model may be closely related to <i>the half-rationality</i>, a new concept which Professor Sakai, the President of the Japan Section of Regional Science Association International, introduces into regional scientists.
