The idea of “too big to fail” comes from the experience of bank runs in the early 20th century. The answer then and now is deposit insurance. But such insurance has its limits, just like any insurance contract.
Lawrence White suggests that bank runs can be prevented if we redesign the banking system. He suggests a money substitute that just might work, except that the big banks will have, perhaps, a hard time making money on fees.
It seems that the idea can be integrated with the emerging market for cryptocurrencies. How?
