If you are interested in financial, and economic language you can try listening to the same internet radio show that I listen to.  DH Unplugged is a great show involving a market analyst and a money manager who discuss the weekly trends in the economy, as well as political and future trends.  The hosts do a good job to teach, as well as inform and even joke around a bit.  It might be tough listening, but if you have the chops it’s a good choice to improve your listening increase your economic vocabulary.
