URGENT ANSWER REQUIRED!

Hi, I have a question regarding an exercise in Asset pricing about Redundand Assets. (I don't have more information, this is all what I have for this execise)

On a) we should figure out whether the securities are call options, put options, straddles, bonds, etc..

2. Redundant Assets (6 points) Consider a two-period economy with 4 states of nature in the second period) and 5 securities. (10 201 101 1 2 A = (A,A,A,A4,A5) = 4',AA 1 1 0 1 3 1 2 0 0 4 Securities 2 to 5 are traded at current prices of (P2, P3, P4, Ps) = (1,.8,.4,2.9) (in the first period). a. How could you interpret these securities? b. Can you determine equilibrium prices that are free of arbitrage? How can you interpret those prices? c. Determine both, the risk neutral as well as the physical probability measure. How do they relate to each other? d. Now suppose that a new security A6 = (2,0,0,2)' is successfully launched in the market and trades at P6=1.2. Does this innovation increase welfare? Explain carefully! 2.
