The central bank of a country, whose economy depend on exports, was proposing what they called Quantitative Easing, which is to buy back bonds to boost the economy by leaving lots of cash in the hands of banks, which are supposed to lend this cash. The congress, on the other hand, was screaming that a huge investment in roads, bridges, infrastructure in general, will do the trick. Which of them is right?, explain why and remember that the island economy is driven by exports.
