4. (15 points) As we discussed in class, financial industry is a field that has a lot of room for improvement. The switch from multiple-price to single-price in Treasury security auctions, the growth of P2P lending, and the adoption of blockchain technology are examples of how traditional models can be changed. Please pick up one type of financial institution/service/product/regulation of your own choice that you think has room for improvement and try to think out of box to design a possible new way or model for that field. Please indicate specific limitations or problems in the existing way or model when developing your proposal. 4.
