Calif Manag Rev 46 (2): 6-22 According to our overview of previous literatures, collective agreements and two-part revenue-sharing are the most common approaches to coordination. Some researchers, for example Jing-Yan et al. , have already studied TTC performance in a CLSC under symmetrical and asymmetrical situations;  has shown that revenue-sharing contracts and quantity rebates are themselves necessary, which may encourage producers to recover used products. In addition, they found that revenue-sharing contracts and rebate contracts could reduce double marginalization;  analyzed the decentralized inversion parameters, followed by the vote on the income-sharing contract.
As a result, it appears that two-part rate and revenue-sharing contracts are the most common and effective approaches that CLSC members can encourage to carry out collection activities. A reverse pension contract, or “reverse pension,” is the purchase of securities with the agreement to sell them at a higher price at any given time. For the party that sells the guarantee (and agrees to buy it back in the future), it is a buy-back (RP) or repo contract; for the other end of the transaction (purchase of security and consent to the sale in the future), it is a reverse repurchase agreement (RRP) or Reverse Repo.
