The idea creator's optimal choice on residual claims is positively correlated with both how he anticipates the operator's ability and how efficient he could monitor the operator. The returns to the idea creator and the operator are negatively correlated with the degree of information symmetry and the amount of insolvency remnant, but are positively correlated with the levels of asset prices.
