o problema dos "haircuts"

Some say Western governments shouldn't "accept" what the market says. "Who do these trading people think they are," I hear from the lips of the educated but financially-illiterate political elite. Let's be clear – if global bond markets stop lending to a number of large Western economies, we are in the realms of unpaid state wages and pensions, transport chaos and closures of schools and hospitals – sparking the prospect of serious civil unrest. Forgive my intemperate tone, but these are the dangers we face. And I'm afraid the only rational response to Thursday's announcement is that the probability of such undesirable outcomes has just been increased.
