Imagine you are the owner of a farm that grows and sells kilograms of corn, which can be modeled after a perfect competition market. You know that there are 1,000,000 consumers in the market for corn and that they each have a demand function for kilograms of corn (x) below. You also know that you are one of 1,000 farms that each have the supply function for kilograms of corn (q) per hour below: x=10–0.25Px +3I+4Py
q = 40 + 0.5 Px – 4 PL + 400 K

a. Calculate the income elasticity of market demand for corn. What does this mean economically? Is this normal or inferior?
b. Calculate the (own) price elasticity of market demand for corn. What does this mean economically? Is this elastic or inelastic?
c. Calculate the cross-price elasticity of market demand for corn. What does this mean economically? Is this a substitute or a complement?

Galwaysc electronics makes two products. model a requires component a and component c. model b requires component b and component c. new versions of both models are released each year with updated versions of all components. all components are sourced overseas, and abc contracts annually for a quantity of each component before seeing that year’s demand. components are only assembled into finished products once demand for each model is known. for the coming year, alwaysc’s purchasing manner has proposed ordering 500,000 units of component a, 630,000 of component b, and 1,000,000 units of component c. her boss has asked why she has recommended purchasing so much of components a and b when alwaysc will not have enough of component c to fully use all of the inventory of a and b. what factors might the purchasing manager cite to explain her recommended order? explain your reasoning.

Susie buys two goods - rounds of golf and massages. suppose that the price of a round of golf is $20, and the price of a massage is $30. in a typical week susie will play two rounds of golf, getting 20 units of satisfaction from the second round. she normally buys three massages each week, with the third giving her 30 units of satisfaction. if she were to buy a fourth massage in a week, it would give her 20 units of satisfaction. if the price of massages is reduced to $15, which of the following outcomes might we expect to occur? a) susie would leave her consumption choices unchanged because of diminishing marginal utility in the consumption of massages. b) susie would buy more massages and more rounds of golf, as predicted by the substituion effect. c) susie would buy more massages and fewer rounds of golf, as predicted by the substitution effect. d) susie would buy more massage and fewer rounds of golf, as predicted by income effect.
