- Abstract
In a deposit-refund system, not all deposits are refunded; this yields unrefunded deposits that are called unredeemed deposits. If the system is mandatory, it is difficult to decide who should hold these-suppliers, recyclers or government. However, from the perspective of economics, examining the allocation of the unredeemed deposits is not enough. We investigate the optimal design of deposit-refund systems considering the allocation of unredeemed deposits in detail from the economics aspect. The conclusions can be summarized as follows. The refund should be equal to the sum of the following three: (1) the suppliers' marginal net revenue from collecting and treating used deposit-refund goods, (2) the marginal negative externality, and (3) the deposit multiplied by the share of the unredeemed deposits that the government and the recycler collect from the supplier. The weight for the sum of (2) and (3) is the marginal product for the supplier multiplied by that for the recycler.
