SEC Regulation Crowdfunding and Regulation

I need a research paper about the pros/cons of the SEC’s proposed rules regarding Regulation Crowdfunding (Title III of the JOBS Act) and Regulation A+ (Title IV of the JOBS Act). Particular attention should be paid to the costs that small businesses are burdened with under Regulation Crowdfunding, the liabilities that crowdfunding intermediaries face, and blue sky preemption under Regulation A+.
