Suppose a person has a utility function U(x1,x2)= xa1+xa2, which
she maximizes subject to her budget constraint, px1 + qx2 = m,
where p, q, m are all positive. Use the Lagrangian method to solve
the maximization problem, and find the demand functions for the
consumer. Show that the demand functions are homogeneous of degree
zero in prices (p, q) and income (m)

Part 1: Optimization with inequality constraints 1. A consumer lives on an island. Her utility function is U = (x²y)1/3. She produces two goods, x and y. She faces a production constraint and an environmental constraint: Her production possibility frontier is: x² + y2 s 300. She faces an environmental constraint given by x + y = 200. a) Set up the Lagrangian function. b) List all of the Kuhn-Tucker conditions. c) Interpret...

Question 1 (20 marks) (a) A consumer maximizes utility and has Bernoulli utility function u(w)/2. The consumer has initial wealth w 1000 and faces two potential losses. With probability 0.1, the consumer loses S100, and with probability 0.2, the consumer loses $50. Assume that both losses cannot occur at the same time. What is the most this consumer would be willing to pay for full insurance against these losses? (10 marks) (b) A consumer has utility function u(z, y) In(x)...

Question 1. (Consumption-Saving Problem): Suppose that a consumer lives for two periods. The utility function of the consumer is given by with u> 0 where c and c2 are consumption in period 1 and period 2 respectively. Sup- pose that consumer has income y in the first period, but has no income in the second period. Consumer has to save in the first period in order to consume in the second period. Let s be the savings in the first...
