DP12234 Optimal Management of Transfers: an Odd Paradox
In this paper we consider transfers towards needy people but, unlike Atkinson, we assume that there exists a serious preference misalignment between the transfer maker and the beneficiary. The former wants to reduce the resulting discrepancy through monitoring the use of the transfer and imposing sanctions if the discrepancy proves too large. This external discipline combines with the ’internal discipline’ of the beneficiary, that is his/her willingness and ability to align with the transfer maker’s objective. Besides the fact that costs of monitoring and sanctioning are explicitly taken into account, an original feature of our model is that the two types of discipline are made comparable: they can be summed up to obtain an aggregate discipline. We show that, paradoxically, an (exogenous) improvement of internal discipline may be over-compensated by a fall of external discipline. As a result, total discipline actually decreases and the discrepancy between the actual and the intended uses of the transfer increases instead of decreasing. This paradoxical outcome is obtained despite better preference alignment as cost savings are optimally implemented. Another consequence is that the relationship between internal and total disciplines may be non-monotonous.
