(a) State the necessary and sufficient conditions for consumer equilibrium.

(b) Choose two goods and their corresponding prices, such that the consumer is in disequilibrium, i.e., he or she gets more marginal utility from one good than from the other given the goods prices. Indicate how the consumer will change her spending habits to return to equilibrium.

(c) What role does the laws/principle of diminishing marginal utility play in the process you described above?

(d) Characterize as best as you can the substitution effect and the income effect on the consumer equilibrium. You may use graphs.

Consider a consumer with Cobb-Douglas preferences over two goods, x and y described by the utility function u(x, y) = 1/3ln(x) + 2/3n(y) 1. Assume the prices of the two goods are initially both $10, and her income is $1000. Obtain the consumer’s demands for x and y. 2. If the price of good x increases to $20, what is the impact on her demand for good x? 3. Decompose this change into the substitution effect, and the income effect....

A consumer’s preferences over two goods (x1,x2) are represented by the utility function ux1,x2=5x1+2x2. The income he allocates for the consumption of these two goods is m. The prices of the two goods are p1 and p2, respectively. Determine the monotonicity and convexity of these preferences and briefly define what they mean. Interpret the marginal rate of substitution (MRS(x1,x2)) between the two goods for this consumer.   For any p1, p2, and m, calculate the Marshallian demand functions of x1 and...

Consider a one-period closed economy, i.e. agents (consumers, firms and government) live for one period, consumers supply labor and demand consumption good, whereas their utility function is in the form of log(C−χN1+ν/1+ν ) (GHH preference). Firms supply consumption good and demand labor and their production function is y = zN^1−α. The government finances an exogenous spending via lump-sum taxes. Suppose there is a positive shock on χ which means the consumers favor leisure (or dislike labor) by much more than...
