   The citations are good, some could be better.  And dont trust everything you read!  ;)  Hell, I've read some amazingly deceptive stuff in graduate school, some written by Nobel prize winners, columbia professors, Berkely graduates...people you would think are honest.  And trust me when I'm saying I'm giving them the benefit of the doubt...they are either dishonest or stupid.  (Example, Nita Rudra's slaughtering of the stolper samuelson model so she could argue that globalization isnt working for the poor in africa because they are unable to unionize...thus misinforming readers to achieve a pro union objective by mischarachterizing stopler samuelson and the enviornment it argues would bring about higher wages for labor...but that is a whole nother story I wont bore you with)  (Gibby )
