JPMorgan CEO Jamie Dimon believes that regulators in the USA and United Kingdom should make it easier for companies to go public. Dimon pointed out in an interview in London on Tuesday that research on small companies has declined, while litigation and regulatory filing fees have increased. However, he added that there is an increasing backlog of IPOs. "I believe we have a responsibility to make listings easier and cheaper. We must find a way to do this," Dimon said. Dimon also suggested allowing more mid-sized banks to merge.
