I thank Dr. Sweeney for the presentation. In his paper, Dr. Sweeney suggests moving to a debt servicing cost as a benchmark of fiscal sustainability. How would that benchmark be anchored? Would it be as a percentage of GDP? Could Dr. Sweeney explain in greater detail he would like to have seen in relation to that?
