The solution should have a price and quantity solution with a reasonable economic interpretation for real-world goods or services that are closely related. The solution should take two forms: one using the elimination of variables approach and the other using a technique from matrix algebra

- Which of the following statements regarding managing demand uncertainty is FALSE: A Shortening the lead time of raw material acquisition can lower the cost of demand uncertainty. B To reduce the cost of demand uncertainty, a sufficiently large minimum order quantity at an early production stage is preferred. C Obtaining market information earlier leads to more reactive capacity. D Under the postponement strategy, the effect of product pooling is stronger when demands for customized products are more negatively correlated.Given below are the demand and supply functions for three interdependent commodities. Qd1 = 110 – 4P1 + 3P2 – 4P3 ; Qs1 = 2P1 – 20 Qd2 = 46 + 2P1 – 4P2 + 4P3 ; Qs2 = –14 + 2P2 Qd3 = 20 – P1 + 4P2 – 2P3 ; Qs3 = 2P3 – 10 (a)Determine the equilibrium prices and quantities for the three commodity Market model. (b)Then compute the price and cross elasticities of demand for the third market and interpret their coefficients.List the chief advantages and shortcomings of using breakeven analysis in pricing decisions. Breakeven analysis is a means of determining the number of goods or services that must be sold at a given price to generate revenue sufficient for covering total costs. It is easily understood by managers and may help them decide whether required sales levels for a certain price are realistic goals. Its shortcomings are as follows. First, the model assumes cost can be divided into fixed and variable categories and ignores the problems of arbitrarily making some allocations. Second, it assumes that per-unit variable costs do not change at different levels of operation, ignoring the possibility of quantity discounts, more efficient use of the workforce, and other possible economies. Third, the basic breakeven model does not consider demand. It is a cost-based model and fails to directly address the crucial question of whether consumers will actually purchase the product at the specified price and…

- For a certain company, the cost function for producing x items is C(x)=30x+200 and the revenue function for selling x items is R(x)=−0.5(x−110)2+6,050. The maximum capacity of the company is 170 items. The profit function P(x) is the revenue function R(x) (how much it takes in) minus the cost function C(x) (how much it spends). In economic models, one typically assumes that a company wants to maximize its profit, or at least make a profit! 1. Assuming that the company sells all that it produces, what is the profit function? P(x)= ? 2. What is the domain of P(x)? 3. The company can choose to produce either 80 or 90 items. What is their profit for each case, and which level of production should they choose? Profit when producing 80 items=? Profit when producing 90 items=?In general, the outputs include all of the items that are ____________________. Choices: A.at the very end of the dependency tracing path( B.in the middle or intermediate calculation C.anywhere in the model layout D.placed as part of the input assumptions E.None of the answers is correct.Based on arguments made by Friedman and Fama, which of the following requirements must be fulfilled for noise traders to affect markets in equilibrium?

TRUE since the marginal benefit of one extra passenger is more than $75 D.
