There is plenty of conventional macroeconomics in De Gregorio’s story, including the value of careful fiscal policy and the advantage of maintaining a flexible exchange rate guided largely by supply and demand in the market. When countries seem committed to a fixed exchange rate (say, relative to the US dollar), firms and individuals feel encouraged to borrow in foreign currency (like the dollar) in order to lock in what are typically lower interest rates.
德格雷戈里奥的理论包含了很多传统宏观经济学，包括审慎的财政政策的价值以及维持以市场供求为主要决定因素的弹性汇率的好处。当国家承诺固定汇率时（如相对美元汇率），企业和个人得到了激励借入外币（如美元）以锁定通常较低的利率。
