Abstract: Ronald Coase famously argued that “if an economist finds something – a business practice of one sort or other – that he does not understand, he looks for a monopoly explanation”. So it is with credit card interchange fees. Intellectual confusion has led to the phenomenon of interchange fees being misdiagnosed as being a monopoly problem leading to inappropriate policy intervention. Following George Stigler’s path breaking analysis of the US Security and Exchange Commission he claimed that financial regulation was “founded upon prejudice and … reforms are directed by wishfulness”. In our opinion, Australian regulatory attitudes towards interchange fees should be placed into the same category: reforms initiated by ignorance and anti-bank prejudice.
