Detecting Type-B Arbitrage with (ADLP) - Practice For type-B arbitrage the following conditions need to be satisfied: Po(y) = Six; < 0, (i) i=0 Esi(w;)x; > 0, j = 1, 2, ..., m, (ii) i=0 > Si(w;)x; > 0 for at least one index j (iii) i=0 We can find such an investment x (if one exists) by solving m ОРТ :3 S{(w;)X; min i=0 subject to E Si(w;)x; > 0, j= 1,2, ..., m. (ADLP) i=0 E sixi <0 i=0 Define OPT = -o if the problem is unbounded

Consider the linear program from lecture slides for detecting type-B arbitrage in practice. Leave the constraints unchanged but replace the objective function with - E a; E, S{ (w;)æ; for some vector a = (a1, ... , am). For what a does this modified LP have 0o value if and only if type-B arbitrage exists ? Ο Σ α = some positive constant aj 2 0 for all j aj > 0 for all j All of the above O None of the above
