General Equilibrium: Consider an economy that can produce tacos (X) and hamburgers (Y). Let the production possibilities frontier (PPF) be Y2 = 100-4X2 (Eq. 1) or, equivalently ? = √100 − 4?2 (Eq. 2) (for positive values of tacos and hamburgers). This means that the rate of product transformation (RPT), the number of hamburgers that must be given up to get one more taco along the PPF, is − ??/?? = 4?/(√100−4?2) a. Suppose initially that the price of X...

Suppose X, Y and Z are three different random variables. Let X obey Bernoulli Distribution. The probability distribution function is p(x) = Let Y obeys the standard Normal (Gaussian) distribution, which can be written as Y ∼ N(0, 1). X and Y are independent. Meanwhile, let Z = XY . (a) What is the Expectation (mean value) of X? (b) Are Y and Z independent? (Just clarify, do not need to prove) (c) Show that Z is also a standard...
