Macroeconomics

Find at least one article from the real world that discusses one of the dominant currencies: Yuan, Dollar, Euro, Pound, etc. and compares the rise/fall of the exchange rates (or relative value of that currency) in the global market. Please to refer to the article "A Concise Guide to Macro Economics, Second Edition, chapter 7, Understanding Exchange Rates" and "Note on International Trade" when explaining the currency fluctuation. We are not asking you all to become experts overnight in this field...but I am looking for business acumen relating to understanding how exchange rates and trade balances work in the business world. 

You are welcome to pose questions (post a link to the article you find so that others can access it) if you are unsure about how to explain a phenomenon.....150wd ct
