Q2. A bank is considering two types of new investment options: Yield Bond (YB) and Equity Income (EI). Three possibilities are being considered: Yield Bond only; Equity Income only; and offering both YB and EI. Concerning the uncertainty about future demand, the bank management team estimates two potential demands for each type of investment: strong or weak, with the following probability assessments:
Equity Income Demand
| 
 Yield Bond Demand  | 
 Weak  | 
 Strong  | 
| 
 Weak  | 
 0.15  | 
 0.45  | 
| 
 Strong  | 
 0.25  | 
 0.15  | 
The projected bank profit, in millions of dollars, has been also forecasted:
| 
 Only Yield Bond  | 
 Only Equity Income  | 
|
| 
 Weak  | 
 200  | 
 300  | 
| 
 Strong  | 
 400  | 
 600  | 
Both Yield Bond and Equity Income
Equity Income Demand
| 
 Yield Bond Demand  | 
 Weak  | 
 Strong  | 
| 
 Weak  | 
 100  | 
 550  | 
| 
 Strong  | 
 350  | 
 700  | 
a) Determine the optimal strategy.
b) Determine the expected value of perfect information.
Let us assume we have 3 strategies such as
Yield Bond, Equity & Yield Bond-Equity Income both
We have Probability assesment given for both strategies in together hence need to find probabilities using bayesian probability
P(Yield Bond with Weak Demand | known demand for Equity Income)= 0.2/0.5 =0.4
P(Yield Bond with Strong Demand | known demand for Equity Income) = 1-P(Yield Bond with Weak Demand | known demand for Equity Income) = 0.6
Then Expected Income from Yield Bond
0.4(200)+0.6(400)=320
Expected income from Equity Income Demand
0.3/0.5=0.6 and 0.2/0.5 = 0.4 similarly usnig Bayesian probabilities
Expected income from Equity Income Demand
0.6(100)+0.4(600) =300
Now lets assume strategy when both are considered
weak,weak + weak,strong + strong,weak + strong,strong= 0.2(100)+0.3(300)+0.3(200)+0.2(700)=20+90+60+140=310
Hence given demand probabilities we can say that only equties would fetch better profits than that of others
To find Value of the constant B we need to have atleast expectedd value of strategy is 320
we need to have value B wich makes expected value of Equity Income-Yield bond atleast equal to 320
320= 20+90+60+0.2(B) that nakes B >=750
This is my solution..
Thank you
