A. using the data under d1 and d2, calculate the cross elasticity of lorena's demand for golf at all three prices. (to do this, apply the midpoints approach to the cross elasticity of demand.) at $50, cross elasticity = . at $35, cross elasticity = . at $20, cross elasticity = . is the cross elasticity the same at all three prices? . are movies and golf substitute goods, complementary goods, or independent goods? .

b. using the data under d2 and d3, calculate the income elasticity of lorena's demand for golf at all three prices. (to do this, apply the midpoints approach to the income elasticity of demand.) at $50, income elasticity of demand = . at $35, income elasticity of demand = . at $20, income elasticity of demand = . is the income elasticity the same at all three prices? . is golf an inferior good? .

The u. s. stock market has returned an average of about 9% per year since 1900. this return works out to a real return (i. e., adjusted for inflation) of approximately 6% per year. if you invest $100,000 and you earn 6% a year on it, how much real purchasing power will you have in 30 years?

Suppose that two firms produce differentiated products and compete in prices. as in class, the two firms are located at two ends of a line one mile apart. consumers are evenly distributed along the line. the firms have identical marginal cost, $60. firm b produces a product with value $110 to consumers. firm a (located at 0 on the unit line) produces a higher quality product with value $120 to consumers. the cost of travel are directly related to the distance a consumer travels to purchase a good. if a consumerhas to travel a mile to purchase a good, the incur a cost of $20. if they have to travel x fraction of a mile, they incur a cost of $20x. (a) write down the expressions for how much a consumer at location d would value the products sold by firms a and b, if they set prices p_{a} and p_{b} ? (b) based on your expressions in (a), how much will be demanded from each firm if prices p_{a} and p_{b} are set? (c) what are the nash equilibrium prices?

Differentiate between the trait, behavioral, and results-based performance appraisal systems, providing an example where each would be most applicable.
