Benefit of forming a fund

Why did partnership funds became so widely used? The pass-through nature is of course an important element, but if that is the sole benefit, then it is indifferent from just simply not establishing a fund. Below are some of the factors I can think of:

  1. Gathering multiple investors: A fund can gather many investors into one pool. It will make investment process much more cost efficient.
  2. Give strong power to the manager: Managers of investment funds tend to have more discretion and decision power compared to directors of ordinary corporations. This creates incentives for the managers to establish an investment fund.
  3. Anonymity: In some cases, the investors do not want to make their names known to the investee (or to the public, if the investment requires public disclosure). A partnership can intervene in between in such case and hide the names of the actual investors behind. But this does not work in some cases.
  4. Reputation: At least in Japan, investment funds have earned decent reputation as of now, and establishing an investment fund has become “cool” thing.
