1. A. Explain how one derives the indifference curves from a 3-dimensional utility function. Draw a graph and explain. Which principle explains the concave shape of the utility function? Why?
B. Explain the concept of Consumer Equilibrium. How does it relate to utility maximization? Draw a graph and show where consumer equilibrium occurs. Write down the equation that holds at the consumer equilibrium.
C. Explain how one can drive the Law of Demand from Consumer equilibrium.
D. Assume that there are 2 goods, X and Y and P(X) = $20 and MU(X) = 100, and p(Y) = $50. Assuming that the consumer is currently maximizing her utility, compute MU(Y). SHOW THE EQUATION YOU USE AND SHOW YOUR COMPUTATION.
2. A. Define and explain Short Run cost curves (TOTAL, AVERAGE AND MARGINAL COST CURVES). DRAW GRAPHS AND LABEL EACH CURVE ON THE GRAPH. Explain the “law of diminishing returns”. State the economic reason behind it.
B. Explain the Long Run Average Total Cost curve. Explain the concepts of Economies of Scale; Constant Returns to scale; Diseconomies of scale. Draw a graph.
3. A. Write down the 4 major characteristics of Perfectly Competitive markets.
B. Draw 3 GRAPHS AND EXPLAIN THE 3 POSSIBLE SITUATIONS THAT A COMPETITIVE FIRM CAN FACE IN THE SHORT-RUN.
C. Explain the LR equilibrium in a perfectly competitive market. Draw a graph.
