I want to ask you about MERCOSUR, a regional trade area encompassing Brazil, Argentina, Paraguay, Uruguay. Venezuela (suspended in 2016); associate countries are Bolivia, Chile, Colombia, Ecuador, Guyana, Peru and Suriname.One of the discussion within MERCOSUR member countries is to adopt a single common currency to become a common market much like the EU. What issues should they consider before they accept or reject a common currency? Should associate countries be included inthis endeavor or only include current member countries? Why or why not?
