Somewhat of a tangent but negative interest rates are associated with currency deflation. Does anyone know of any prominent economists who argue that deflation may be a good thing? I know the overwhelming consensus is that you want something like 2% or 3% inflation to ensure market growth but I'm always interested in alternative perspectives, particularly because personally I'm not convinced that you necessarily want (or need) perpetual growth.
