Preventing future financial crises is a matter of creating better financial instruments, Nobel-winning economist Robert Shiller wrote in his 2012 book 'Finance and the Good Society'. To that end, the right fintech tools would go a long way toward encouraging innovative and healthy development in the finance sector. While a so-called regulatory sandbox to play in is probably not the structure Shiller had in mind to create these better financial instruments, American lawmakers are proposing such a solution, following in the footsteps of the United Kingdom, which unveiled a similar initiative earlier this year.
