Ainda por causa desta polémica, Krugman admite que ter acima de 90% de dívida é negativo para o crescimento económico de um país!
There is, as everyone in this debate has acknowledged, a negative correlation in the data between debt and growth. As a result, draw a line at any point — 80 percent, 90 percent, whatever — and countries with debt above that level will tend to have slower growth than countries with debt below that level.
There is, however, an enormous difference between the statement “countries with debt over 90 percent of GDP tend to have slower growth than countries with debt below 90 percent of GDP” and the statement “growth drops off sharply when debt exceeds 90 percent of GDP”. The former statement is true; the latter isn’t. Yet R&R have repeatedly blurred that distinction, and have continued to do so in recent writings.
Já vi os inventores da praça darem as interpretações mais fantásticas a frases de Krugman, mas sempre quero ver como se safam de uma afirmação tão inequívoca como esta.
