Principles of transportation economics
Kenneth Boyer's book Principles of Transportation Economics is a welcome addition to transportation economics literature. It appears to be the ?rst book with that title which is surprising since there seem to be dozens of books titled Principles of Economics. Most economists learnt their ?rst economics from one of these books; perhaps Boyer's book will have an equivalent role for transport economics. There are few alternative textbooks. Kenneth Button's Transport Economics has similar coverage and is written at about the same level but deploys more analytical tools than Boyer's book. However, Button's book is mainly written from a U.K. perspective, a handicap in the North American textbook market. Several books of readings are available but have problems of coverage and varying levels of presentation. Books which are suitable for introductory courses in business logistics or supply chain management have minimal overlap with Principles of Transportation Economics and the di€erences in approach and emphasis make it unlikely that they would be considered for the same courses. The organization of the book is straightforward and logical; it covers transportation demand, cost, pricing, investment, and regulation (of both market power and externalities) in 14 chapters amounting to just over 400 pages. The coverage is very comprehensive ? all modes are covered and a good balance is struck between intercity and urban and freight and passenger. Statistics and information are reasonably current but are based on the U.S. transport system. Although ?ve of the seven illustrations in the introductory chapter's examples of policies guided by transport economics are non-U.S., this is a high water mark for non-U.S. material. The Channel Tunnel is used later as an example and the index has one reference to British Airways, one to Canada, and two to Japan but that is about all the foreign material in the book. Furthermore, international transport gets short shrift compared to U.S. domestic transport. The introductory ?rst chapter should help make students aware of, and interested in, the problems which transport economists ?nd so fascinating. The next chapter on general transport demand contains a very e€ective graphical and numerical explanation of derived demand for freight transport and integrates this with a simple exercise on transport networks and ?rm location. The following two chapters on freight and passenger transport demand provide less analytical content but many pages of statistical information, including a two-page spread on commuting mode share and distance for 50 U.S. metropolitan areas. This information might be interesting for specialists, but it is too much for students and examples would have su?ced. The coverage in these chapters is typically comprehensive although intercity automobile transportation is given less coverage than it deserves. Transportation Research Part E 35 (1999) 291?295 www.elsevier.com/locate/tre The book moves into cost with a good chapter on transport cost concepts, including an extended illustration of airline network economies. Deregulation has made network decisions much more important for airlines and similar carriers and Boyer's example covers many of the major issues. However, the illustration omits explicit consideration of passenger time costs and oversimpli?es the complex aircraft scheduling problems that airlines must address when they construct their route networks and ?ight schedules. Overall, the cost basics are well-presented. The next three chapters deal with ?xed facilities costs, vehicle ownership costs, and vehicle operating costs. Because of the genuine e€ort to include all modes of urban and intercity freight and passenger transport, a total of 90 pages is devoted to these three applied cost chapters. For many purposes, there is simply too much statistical information (e.g., long tables on fuel expenditures by U.S. air carriers from 1972 to 1994 and on tra?c volume, density, speed, and cost relationships, information better presented in a diagram). Other approaches to providing insight into cost relationships and problems could have been used; for example, the descriptions of vehicle costs in Chapters 7 and 8 could have been replaced by an analysis of how carriers should decide what to buy for particular services. An exercise explaining optimal ocean vessel size is included but for most modes the interesting and complex interplay between equipment ownership and operating costs is not discussed. The operating cost savings for urban automobiles and trucks from various forms of intelligent vehicle systems could have been the basis for a good illustration. Chapter 9 covers investment for both vehicles and infrastructure. It includes the elements of investment analysis and illustrations of Union Paci?c's purchase of Overnite Transportation, the Tennessee-Tombigbee Waterway, and investment alternatives for commuter railroad extensions north of New York City. The topic of the ?rst illustration, an intermodal acquisition decision, lies somewhat beyond standard investment analysis techniques and many of the possible motivations for Union Paci?c's purchase are not considered. The Tennessee-Tombigbee illustration is used to explain the mechanics of public sector bene?t-cost analysis but the usual equation is not speci?ed. The commuterrailroad illustration is considerably more informative than the othertwo, principally because it incorporates network issues introduced earlier and social cost issues introduced later. Pricing, the topic of Chapters 10 and 11, is crucial in any transportation economics course. The organization of this material is always a challenge ? Boyer addresses it by starting with a ``golden rule'' for e?cient pricing (price ˆ short run marginal cost) and then working through the application and modi?cation of the rule in di€erent pricing problem settings. In general this works well (although one could criticize treating peak-load pricing as a variant of either congestion pricing or backhaul pricing rather than as a pricing topic of interest in its own right), but there are some problems. One is that the pricing chapters are not always clear on how best to include infrastructure costs when setting prices. The inherent con?ict between Chapter 10 (``E?cient Pricing'') and Chapter 11 (``Paying for Use of Transport Facilities'') is left more unresolved than necessary; bringing in Ramsey pricing earlier than the end of Chapter 11 might have helped. Also, Boyer seems unable to make up his mind as to whether road congestion pricing without the proceeds devoted to road purposes is better than no congestion pricing at all. On page 262 he writes ``It is unimportant what happens to the money collected from driver'' but in the next paragraph he argues ``... tolls whose revenue is simply discarded will make all transportation users worse o€ . . .'' From an e?ciency perspective, if we assume away the administrative and transactions costs, congestion pricing is desirable, but by restricting output and raising price it will reduce the 292 Book reviews / Transportation Research Part E 35 (1999) 291?295 consumer surplus of road users. This is an important and complex issue and while some of its rami?cations are dealt with in a suitable manner, the reader is left without a completely satisfactory resolution. Chapter 12 on market power in transportation starts with a very good extended example of a ?xed facilities monopoly, the Mackinac Bridge in northern Michigan. The discussion of pricing the services of this facility is clear and informative and here students can learn much about avoidable costs, price-setting, and the e€ects of market power. The rest of the chapter deals with market power of transport operators and recognizes the crucial role of infrastructure in establishing and determining the importance of market power and the typical absence of strong market power when infrastructure is shared between carriers. This chapter leads naturally into Chapter 13 on the regulation of market power. The history of ICC regulation of railroads is dealt with e€ectively and shorter sections on regulation of the other intercity modes present a suitable level of detail. Material on the processes and bene?ciaries of regulation, as it used to be practiced, follows and then current U.S. transportation regulation is described. The chapter continues with a summary of the e€ects of deregulation and the public policy lessons that can be drawn from the use of regulation to control market power. The ?nal section takes note of the ongoing presence of now largely unregulated market power present in phenomena such as carrier-controlled gates and slots at airports and strong second-degree price discrimination in airline pricing. The book concludes with a chapter on regulating the social costs of transportation. Chapter 14 starts with a theoretical presentation of the social cost problem in transportation and continues with case studies on automotive air pollution and safety. The pollution case study deals e€ectively with the causes and consequences of automotive emissions although it does not go very far in discussing the dilemmas policy-makers face if they try to optimize emission levels. Although several regulatory and policy dilemmas are discussed, the well-known proposition that there is an optimal level of pollution is not presented. The safety case study, however, does identify the possibility of too much safety regulation and the counter-intuitive result that high safety standards will induce unsafe behavior by car drivers. As a textbook, Principles of Transportation Economics lacks two pedagogical elements that help make a book attractive to students and instructors ? glossaries with the chaptersummaries(because transportation economics has many unfamiliar terms) and question sets. Course instructors may wish to add their own. A ?nal criticism is that, although the level of economics is suitable for upper level undergraduates, the exposition relies more on rhetoric than do many specialized texts in other areas of economics at this level. Some opportunities to use graphical exposition are missed, notably in the pricing chapters, and there is very little mathematical exposition. Also, the discussion of econometric estimation of demand and cost functions seems more elementary than necessary. Overall, this is a worthwhile book. Among its strengths: 1. It is well-written and has fewer than the average textbook's number of editorial errors. 2. One of its main contributions will be to serve as a quick reference to the literature. There are almost 20 footnotes in the average chapter and many contain multiple bibliographic references. 3. The best examples and illustrations (and there are more than mentioned in this review) are very good. Any person with an interest in transportation economics should acquire Principles of Transportation Economics. It is a valuable reference to the ?eld and quali?es, at least in North Book reviews / Transportation Research Part E 35 (1999) 291?295 293 America, as the best current comprehensive textbook for general courses in transportation economics..NULL.NULL
