can you provide its doi number?

if its nowhere to be found then it isnt a publised work paper or it has been removed or flagged.

No unfortunately I haven't found it either :(

Many people cited this paper because of martin's liquidity index which would be useful for my empirical part of my thesis..

Dear Alexandra,

Hope all is well.

I tried my best to search our entire library database, to no avail. Since the paper for the year 1975, perhaps it is not easy to find in many databases.

I recommend you contact the Securities and Exchange Commission (SEC) directly because it is an Economic Staff Paper of their entity.

Hello Prof. Dr. Mazin A.M. Al Janabi,

thanks a lot for your efforts! I really appreciate your help.

I was thinking about the same, so maybe I will give it a try and contact the SEC if I don't find another solution.
