However, I will do what every academic does in such a case: provide you with a few scholarly sources. For Haitian scholarship, you can't go wrong with Jean Price-Mars. However, for matters pertaining to economic development (and the questions you have fielded) consult works of the trusted scholar Mats Lundahl. Although he is not Haitian, he is a scholar of Haiti (his publications contain bibliographic gold mines). Further up the thread, I posted a link to a JSTOR with some reviews of his. I will do you the favor of reproducing them here. You will find your answers in those books (I hope you can read french):
