a) Followings are the institutions that assist deficit and
surplus units to arrange direct financing (without any intermediate
financing institutions) and briefly describe their activities:

fund directly the activities of the companies.
- Bond market - Individuals directly buys newly

company or government.
- Crowdsourcing platform - A lot of
Crowdsourcing platforms such as Kickstarter assist surplus units to
arrange direct financing for deficit units to finance their
projects.
- P2P (Peer-to-peer) lending
platform - Such a platform provides online services by
matching lenders with borrowers for direct financing.

b) Followings are the main implications of the Efficient market
hypothesis (EMH):
- The efficient market hypothesis (EMH) tells that all available
and relevant information is already incorporated into market prices
and so the value of the entity reflects its true value and thus
there are no underpriced or overpriced entities for taking
arbitrage activities. It assumes a negligible transaction cost of
incorporating the information.
- As the value reflects all information, there is no way to investors can systematically
outperform the market and profit from mispricings, because such
opportunities would never come.
- In such a world, active investors can't do anything. That is,
there is no price-arbitrage opportunity for cashing in. So, passive
index investing is the right thing to do.
