oblem 1 Ralph consumes apples (A) and bananas (B). His Marshallian demand for bananas is B ∗ (pA, pB, I) = I 0.4p 0.2 A 3p 0.6 B . (a) Find the income elasticity of demand for bananas (eB,I ) and interpret the value. Are bananas an inferior or normal good? (b) Find the own price elasticity of demand for bananas (eB,pB ) and interpret the value. Does the own price elasticity of demand for bananas depend on the value of pB? (c) Find the cross price elasticity of demand for banan...

Problem 1 Suppose that an individual with income I cares about two goods, X and Y . The prices of the two goods are pX and pY . The individual has the utility function U(X, Y ) = X 2 5 Y 3 5 . (a) Derive the Marshallian demands for the two goods. (b) Find the indirect utility function. Solution (a) To derive the Marshallian demands, we use the Lagrangian method. The budget constraint is pXX + pY Y = I, which we can rewrite as I − pXX − pY Y = 0. We set up the Lagrangian funct...

His Marshallian demand for burrito bowls is B ∗ = I 0.4p 0.3 C 5p 0.7 B (a) Find and interpret the income elasticity of demand for burrito bowls (eB,I ) and interpret the value. Are burrito bowls an inferior or normal good? (b) Find the own price elasticity of demand for burrito bowls (eB,pB ) and interpret the value. Does the own price elasticity of demand for burrito bowls depend on the value of pB? (c) Find the cross p...

A Predator-Prey Model Previously, we studied and simulated the Lotka-Volterra predator-prey model (which you initially saw as the "shark-tuna model"). Now, we will study a different predator-prey model, termed the Holling-Tanner model, that incorporates somewhat different (and more realistic) biological assumptions. As before, we will call our prey population and our predator population . We will assume that, in the absence of predators, the prey population would grow logistically. T...
