Description:
<jats:p>The purpose of this research is twofold : firstly, it presents the economic justifications for deposit insurance schemes as well as the features of such schemes identified as « optimal » in the literature in order to avoid moral hazard and adverse selection phenomena. Thus, according to the literature, deposit insurance should be limited, compulsory, universal and the fees paid by the banks should directly depend on each bank's risk level. Secondly, we test two alternative ways of calculation for the fees paid by the banks to the deposit insurance. The first method consists in drawing a comparison between the insurance fee and a put option, whose price may be calculated from each bank's investment risk. The second proposal relies on a model of banking behaviour wich determines a « socially optimal » insurance fee. Such a fee should indeed maximise the banks' profits when no bank fails and depositors indemnities when the bank is going bankrupt.</jats:p>
