4. In the context of simultaneous equations modelling, which of the following statements is TRUE concerning an exogenous variable? (a) The values of exogenous variables are determined within the system (b) The exogenous variables are assumed to be fixed in repeated samples (c) Reduced form equations will not contain any exogenous variables on the RHS (d) Reduced form equations will contain only exogenous variables on the LHS.
In the island nation of Autarka, cardboard boxes are manufactured by four rms: Andrew'sIndustries, Brett's Boxes, Carla's Cardboard, and Delia's Durables. In Autarka, cardboard boxes are sold in bundles of 100. At present, the market price for a bundle of boxes is $30. The technology for manufacturing cardboard boxes is readily available and common to all manufacturers. The cost of plant and machinery for a rm in the box manufacturing business is $7,000,000 per year. The labour, material, and energy cost of producing abundle of 100 boxes is $20. A market study indicates that demand for cardboard boxes is given by the function,P= 40 - Q/500,000 ;where P represents the price of a bundle of 100 boxes, and Qis the total number of bundles of boxes sold each year. Using the information provided in the scenario, derive a total cost function fora typical cardboard box manufacturer. Use QA to denote the quantity produced by thetypical firm.
1. Assume you must choose between two mutually exclusive alternatives: A or B. The explicit benefit you receive from alternative A, bª, is equal to $100. And, the explicit cost of choosing alternative A, c*, is $80. Also, the explicit benefit to choosing alternative B, b", is $120. What is the accounting return for choosing alternative A, r^? Given r and b", what is the explicit cost that you are willingness to pay (WTP) for alternative B, WTP"? Please include the formulas from class in your answer. How would WTPB change ifr^ increased by $5? Explain. your Using the original set of values for explicit costs and benefits, what would be your economic return to choosing alternative How does this relate to the concept of consumer surplus? if the price that you were charged was $95? Please interpret.

Problem 6Cannes Croissants (not a real company) wishes to determine the optimum production quantity for its topselling product, almond croissants. The annual demandfor almond croissants is 12,000 units. The setup costs fora production run of the croissants is US$15. The holdingcost per unit per year is US$0.50. Production is mostefficient when 80 croissants are produced per day. Thecompany operates 300 days during a year.a What is the economic production quantity (EPQ)?b How many production runs will there by per year?c What is the maximum inventory level?d What is the total annual cost (in US dollars)?e What is the length of a production run in days?
The revenue from the sale of a product is, in dollars, R = 1500x + 3000(2x+3)-1 - 1000 where x is the number of units sold. Find the marginal revenue when 200 units are sold. (Round your answer to two decimal places.) $ Interpret your result. If the sales go from 200 units sold to units sold, the revenue will increase by about $ Suppose that the weekly sales volume y (in thousands of units sold) depends on the price per unit (in dollars) of the product according to the following formula. y = 30(3p+ 1) −2/5, p > 0 (a) What is the rate of change in sales volume when the price is $24? (Round your answer to three decimal places.) dy = dp (b) Interpret your answer to part (a). (Round your answer to the nearest whole number.) If the price increases $1, the sales volume will decrease by If the demand for q units of a product priced at $p per unit is described by the equation p = 500 √29 + 7 find the rate of change of p with respect to q. dp = dq 1 units.
