2) Briefly describe the structure of a decision-making process as discussed in your textbook.Answer: The textbook presents this structure in a form of a pyramid. At the top of the pyramid arepreferences, which directly control the choices made. The next tier is composed of people and politics.Politics means the use of power in organizations. The next tier is a collection of facts. The facts, whichmay not be verifiable, contribute to the politics and people, and indirectly to the preferences. At thebottom of the pyramid are the activities that contribute to the facts. These include the history of previoussimilar decisions, statistics of various sorts, and a determination of costs.Diff: 2Type:SAPage Ref:4-5Topic: 1.3. Making decisionsSkill: RecallUser1: Qualitative3) Explain the role of a mathematical model in engineering economics.Answer: When one describes something, one does so for a purpose. In the description, one selectsaspects of the real world that are relevant to that purpose. The process of simplifying the complexities ofthe real world is necessary for any engineering analysis. This process of simplification is calledabstraction or a model. Once a model is developed, it is used to analyze a situation, and perhaps makesome predictions about the real world. The analysis and the predictions are then related back to the realworld to make sure that the model is valid. The role of abstractions is to develop a viable mode of thereal world.Diff: 2Type:SAPage Ref:6Topic: 1.4. Dealing with abstractionsSkill: RecallUser1: Qualitative4) How should engineers address moral questions associated with economic evaluation of engineeringprojects?Answer: Engineers have a responsibility to society to behave ethically and responsibly in all ways.When many different issues must be taken into account in engineering decision making, it is oftendifficult to determine what course of action is ethical. There are no general answers to difficult moralquestions. Practicing engineers often have to make choices with an ethical component, and cansometimes rely on no stronger foundation than their own sense of right and wrong. More informationabout ethical issues for engineers can be obtained from provincial professional engineeringorganizations.Diff: 1Type:SAPage Ref:8-10Topic: 1.5.

5) Suppose that you are about to start a new business: You will provide consulting services for thosewho want to launch their own web-sites. What major decisions based on the subject matter ofengineering economics should be made before you set up your business activities?Answer: You have to evaluate the expected future costs and benefits of your enterprise. In doing so, youhave to understand your final product and identify a market for that product. As a result, you will be ableto evaluate your expected revenues. This is known as demand-side analysis. On the supply side, youhave to understand all materials, efforts and services involved in producing and/or providing yourproduct. This will give you a cost structure. Then you have to define your planning horizon in order touse economic forecasts of major macroeconomic variables such as interest rate, inflation and others.You have to understand the Canadian tax system as well. If you are uncertain about values of somevariables involved, you have to use principles of sensitivity analysis. All this is the subject matter ofengineering economics.Diff: 3Type:SAPage Ref:3-5, 11Topic: 1.4. Dealing with abstractionsSkill: AppliedUser1: Qualitative6) As a University student, when you look for a new apartment, what economic criteria consistent withthe subject matter of engineering economics do you apply?Answer: You have to understand your budget in terms of cash inflows and outflows. Cash inflows mayinclude: a fellowship, a grant, a loan, an allowance provided by parents and others. Cash outflows toconsider are: costs of utilities, transportation cost, cost of textbooks, tuition fee, food expenses, andothers. As well, time should be explicitly introduced into your economic analysis. Therefore, forexample, a more expensive apartment closer to the University can be preferred to a cheaper one faraway, based on transportation costs.Diff: 2Type:SAPage Ref:3-5Topic: 1.3. Making decisionsSkill: AppliedUser1: Qualitative7) Suppose that in order to finance your studies at the University, three options are available to you: (i) astudent loan, (ii) a student line of credit, and (iii) a part-time job at minimum wage. In making yourdecision, what factors should be taken into account and why?Answer: Both a student loan and a student line of credit represent borrowing. There are costs associatedwith borrowing and it is necessary to compare them. In general, a student loan is interest-free as long asyou stay in school, while a student line of credit is not interest-free. It means that the costs of borrowingassociated with a student loan are lower. Of course, earning your own money is a good option since youavoid paying costs of borrowing. On the other hand, if you work you forgo opportunity to spend thistime on your studies. There are some costs associated with that opportunity, called opportunity costs. Ifthe opportunity costs of working exceed the costs of borrowing under student loan, then the latter is thebest option. Otherwise, working is a better option.Diff: 3Type:SAPage Ref:3-7Topic: 1.3.

Making decisionsSkill: AppliedUser1: Qualitative9) When evaluating an engineering project, what types of constraints does a decision maker face?Answer: A project might be technically feasible and the cheapest solution to a problem, but if it doesn'tearn money at the minimum rate required by the company, it should not be done. The decision makertherefore has to be aware of the financial constraints on the problem. In addition, an engineering projectcan meet all other criteria, but may cause detrimental environmental effects, so we must also considerenvironmental constraints. Finally, any project can be affected by social and political constraints.Diff: 2Type:SAPage Ref:3-6Topic: 1.3.

Theloan is interest-free for as long as Stan is a full-time student. After graduation, he will have to start re-paying the loan within 6 months including interest. Is this a good decision? Why?Answer: Yes, this is a good decision. Stan can borrow $20 000 for four years or $25 000 for five yearsfor free. If this money were invested in a mutual fund or in financial securities, it would earn somereturn. Or if Stan borrowed the money from a commercial bank, he would pay interest payments toservice his debt. Student loan has no borrowing costs.Diff: 2Type:SAPage Ref:3-6Topic: 1.3.

In order to justify this project, what additional economic information do youneed?Answer: First of all, it is necessary to understand what this value includes. Usually costs are dividedinto capital costs and operating costs and those are two different types of costs. Second, it is necessary tounderstand whether or not the value of total costs is given as of today or at some other time.

How is this circumstance consistentwith principles of engineering economics?Answer: This situation means that the interest rate associated with borrowing is higher than the oneassociated with saving. When you borrow, you convert future worth into present worth. However, whenyou save you convert present worth into future worth. As this example shows, conversion from presentto future worth and vice versa in real life is not the same. This is inconsistent with market equivalence inengineering economics. Market equivalence is based on the idea that there is a market for money thatpermits cash flows in the future to be exchanged for cash flows in the present and vice versa at the sameinterest rate.Diff: 1Type:SAPage Ref:32-33Topic: 2.7 EquivalenceSkill: RecallUser1: Qualitative

3) Stan has invested $1 000 into mutual fund at a 5% annual rate of return, compounded daily. What arethe nominal and effective interest rates in this case? Discuss how these two interest rates affect Stan'sinvestment?Answer: The 5% annual rate of return is a nominal interest rate. The effective interest rate is the actualrate used in financial calculations. In order to convert the 5% nominal interest rate into effective interestrate, we have to use the following formula:ie== 0.05127 or 5.127%.Therefore, when calculating the real return on his investment, Stan should use 5.127% interest rateinstead of 5%.Diff: 2Type:SAPage Ref:26Topic: 2.4 Effective and Nominal Interest RatesSkill: AppliedUser1: Qualitative4) Mary just earned $1 000 and wants to invest the money in Canada Savings Bonds.

8) Maria borrowed $2 000 for five years at a simple interest rate of 6% per year. How much money willMaria repay at the end of five years?Answer: Simple interest rate is a method of computing interest where interest earned during an interestperiod is not added to the principal amount used to calculate interest in the next period (p. 23).Therefore, the interest for each of five years isInterest per year = 2, 000 x 0.06 = $120/yearTotal interest = 120 x 5 = $600The amount due after five years = 2 000 + 600 = $2 600.Diff: 1Type:SAPage Ref:24Topic: 2.3 Compound and Simple InterestSkill: AppliedUser1: Quantitative9) Explain why equivalences are just convenient assumptions. Give examples of two real world financialsituations in which these equivalences do not holdAnswer: Equivalences are needed to calculate and compare different costs and benefits over time. Theyare simplifications which capture the basic properties of cash flows without over-complicating theproblem. They may not hold precisely true in the real world. For example, we borrow at a higher interestrate compared to savings. It means that in real life when we move along a time line in a cash flowdiagram we might see different rates moving in two different directions; however, equivalences assumethat the rate is the same. Another example is the cost of information. We assume (until Chapter 12) thatinformation is free, while in real life information is costly.Diff: 3Type:SAPage Ref:32-34Topic: 2.7 EquivalenceSkill: AppliedUser1: Qualitative

The error when using discrete compounding instead ofcontinuous compounding is smaller the briefer the discrete compounding period is". Do you agree ordisagree with this statement and why?Answer: This statement is correct. With an increase in the number of discrete time periods, the errordecreases. This can be seen by comparing two effective interest rates—compounded daily andcontinuously compounded—using the same nominal interest rate. In this case, the error is negligible.Diff: 2Type:SAPage Ref:28-29Topic: 2.5 Continuous CompoundingSkill: AppliedUser1: Qualitative12) Joan is deciding whether she should remodel her house now or one year from now. If she does itnow, the cost will be $1 500. If she waits one year, the cost is expected to be $1 600. At current interestrate of 5.6%, should Joan remodel her house now or one year from now?Answer: To compare the two alternatives, the concept of mathematical equivalence must be applied.According to the concept, $1 500 now is equivalent to 1 500 x (1+0.056) = $1 584 one year from now.This is less than $1 600 and therefore Joan should remodel her house now.Diff: 1Type:SAPage Ref:32Topic: 2.3 Compound and Simple InterestSkill: AppliedUser1: Quantitative
