Upon explaining
that mpoe loss ... Maybe there's indeed some room for improvement, looks like nothing is going to stop bondholders to increase requested interest and thus they prevent any MPOE profit (to be paid to shareholders). The competition on interest rate is ineffective, as bondholders seems to calculate that they won't get whole interest anyway.
Maybe bondholder with lower asked interest should be rewarded by lower risk (allocate lesser part of loss to him)?
The bond auction actually works as a disaster of commons, because everyone receives the same interest as the highest rate accepted, but each bondholder's chances of making the cut are an inverse function of the interest asked. Thus the selfish play is to ask for 0% and make sure you're always going to be on the top of the list, receiving whatever % the tail manages to negotiate.
