Securitization and aggregate investment efficiency
When screening effort is exerted the probability of success conditional on the good state at time 2 is p H where 0 < p H < 1 Alternatively it is only p H − ϕ where 0 < ϕ < p H As above we assume the cost of screening effort at time 1 is proportional to investment ξ I 1 b l and that the fall in asset quality is sufficiently large that lenders only wish to lend when effort has been undertaken
