Under the stop-loss reinsurance model, suppose the total claim follows exponential distribution with mean 1/λ. For given premium P, (a) Derive the retention level M; (b) Calculate the sum of shared variances Var(X*) + Var.X

Time series forecasting maybe used to predict future values of a variable by: A. A simple moving average B. A weighted moving average C. Exponential smoothing D. All of the above

The variance of expected returns is equal to the square root of the expected returns. a. True b. False

Mean-variance expected utility is given by Eu = e-, where e is expected return, v is the variance of the portfolio and tis risk tolerance. Suppose an investor has risk-loving preferences. What can we say about the value of t? Select one: Ot1 O. t>0 O t=0

2) Calculate the envelope set (frontier) for the following four assets and show that the individual assets all lie within this envelope set. 123456 A B E A FOUR-ASSET PORTFOLIO PROBLEM C Variance-covariance 0.01 0.30 0.06 -0.04 0.10 0.01 0.03 0.05 0.03 0.06 0.40 0.02 D 0.05 -0.04 0.02 0.50 F Mean returns 6% 8% 10% 15%

Assuming that the rates of return associated with a given asset investment are normally distributed; that the expected​ return, r​, is 18.7​%; and that the coefficient of​ variation, CV​, is 1.88​, answer the following​ questions:   a. Find the standard deviation of​ returns, sigma Subscript rσr. b. Calculate the range of expected return outcomes associated with the following probabilities of​ occurrence: (1)​ 68%, (2)​ 95%, (3)​ 99%.

1. Determine the expected return and the variance of the portfolio formed by the two assets S₁, S₂ with weights ₁ = 0.6, x2 = 0.4. The assets returns are described by the following scheme: scenario W1 2لا W3 probability 0.1 0.4 0.5 T1 -20% 0% 20% 12 -10% 20% 40%

Internal Rate of Return is the discount rate that sets NPV to 0. True or false?

Suppose two asset returns are described by a two factor model, n = 0% + 11 + 1.82 + e1 2 = -1% + 2/1 + 0.52 + e2 where the volatility of first factor is 30%, the volatility of the second factor is 10%, and the correlation between the two factors is 0.5. Suppose also that the volatilities of the error terms ej and ez are both 10%. What is the covariance of n and r2 ? (Nearest 0.0001).

There is one period. Assume a representative agent with utility function U(ct) = αc_t − βc^2_tassume the following: α = 100, β = 1, and δ = 0.97. Consumption at t = 0 is C0 = 24. At t = 1 one of two states θ1 and θ2 eventuate with probability π1 = 0.5, and π2 = 0.5,respectively. There are two complex securities s^1 and s^2.s^1 has a payoff of 23 in θ1 and 27 in θ2.s^2 has a payoff of 20 in θ1 and 32 in θ2.What is the stochastic discount factor mt+1? hint: Recall mt+1 =δU′(ct+1)/U′(ct)
