Risk control measures in payment systems

The purpose of this paper is to make a comparative analysis of modern gross and net payment systems, emphasizing on the implications of the availability of intraday liquidity in the former and of credit limits in the latter. This allows for the comparison of both the effects on social welfare of each of the two systems and the different risk control instruments analyzed. In a numerical exercise, it is shown first, how it would be legitimate for a benevolent authority a preference for a gross system, like Fedwire, over a net system, like EURO1, for relatively high values, although plausible, of risk aversion. Second, as financial development improves, the preference for a net system shifts either to gross systems or, for some countries, to a cohabitation of both settlement modes.
