As a lifetime engineer, I'm sometimes confused by real and potential economic developments... for example, let's suppose the Fed starts publicly leaning closer and closer to QE2... that would drive the markets to react... but I don't understand how they should be expected to react when the US is printing dollars out of control, and then we use our own money to buy our own debt... I think this means our currency devalues more, but I don't really understand the mechanics and math behind it all. Is there a book or another reference that provides great coverage of market dynamics (including the underlying math theory)? I'm not looking for a book that's all theory... I would like to see example calculations and real numbers... preferably based on the American economy, if possible... but I'd also like to understand how to apply this to Russia, China and other economies as well. Thoughts?
