Concept explainers
(a)
The truth value of the statement “If the tax law has been revised, the deduction is allowed” if the statement “If the deduction is allowed, then the tax law has been revised” is always true.
(b)
The truth value of the statement “If the tax law has not been revised, the deduction is not allowed” if the statement “If the deduction is allowed, then the tax law has been revised” is always true.
(c)
The truth value of the statement “The deduction is allowed only if the tax law has been revised” if the statement “If the deduction is allowed, then the tax law has been revised” is always true.
(d)
The truth value of the statement “The deduction is allowed if the tax law has been revised” if the statement “If the deduction is allowed, then the tax law has been revised” is always true.
(e)
The truth value of the statement “The deduction is allowed or the tax law has been revised” if the statement “If the deduction is allowed, then the tax law has been revised” is always true.

- Given sets X and Y with X ∈ Y, is it always true that P (X) ∈ P (Y) (power sets)? If not, what is a counterexample?arrow_forwardA random variable X takes values 0 and 1 with probabilities q and p, respectively, with q+p=1. find the moment generating function of X and show that all the moments about the origin equal p. (Note- Please include as much detailed solution/steps in the solution to understand, Thank you!)arrow_forward1 (Expected Shortfall) Suppose the price of an asset Pt follows a normal random walk, i.e., Pt = Po+r₁ + ... + rt with r₁, r2,... being IID N(μ, o²). Po+r1+. ⚫ Suppose the VaR of rt is VaRq(rt) at level q, find the VaR of the price in T days, i.e., VaRq(Pt – Pt–T). - • If ESq(rt) = A, find ES₁(Pt – Pt–T).arrow_forward
- 2 (Normal Distribution) Let rt be a log return. Suppose that r₁, 2, ... are IID N(0.06, 0.47). What is the distribution of rt (4) = rt + rt-1 + rt-2 + rt-3? What is P(rt (4) < 2)? What is the covariance between r2(2) = 1 + 12 and 13(2) = r² + 13? • What is the conditional distribution of r₁(3) = rt + rt-1 + rt-2 given rt-2 = 0.6?arrow_forward3 (Sharpe-ratio) Suppose that X1, X2,..., is a lognormal geometric random walk with parameters (μ, o²). Specifically, suppose that X = Xo exp(rı + ...Tk), where Xo is a fixed constant and r1, T2, ... are IID N(μ, o²). Find the Sharpe-ratios of rk and log(Xk) — log(Xo) respectively, assuming the risk free return is 0.arrow_forwardi need help with question 2arrow_forward
