Input-output analysis : Foundations and extensions 2nd ed
We started working on the first edition of this book (Miller and Blair, 1985) in the late 1970s. At that time, input?output as an academic topic (outside of Wassily Leontief?s Harvard research group) was a little more than 25 years old ? 1952?1979, give or take a year at either end. We use 1952 because that was when the first author was introduced to input?output analysis in a sophomore-year economics class at Harvard taught by Robert Kuenne, who later claimed that was the first time input?output had been included (anywhere) in an undergraduate economics course. In 1962, the first author joined the faculty of the Regional Science Department at the University of Pennsylvania. He was asked by then department chair Walter Isard to teach the graduate course in linear models for regional analysis; this was to include a strong input?output component. At that time coverage of the topic in texts was to be found primarily in two chapters of Dorfman, Samuelson and Solow (1958), in Chenery and Clark (1959), in Stone (1961) and in a long chapter on input?output at the regional level in Isard et al. (1960); later there were texts by Miernyk (1965), Yan (1969), and Richardson (1972). The second author of the current text began teaching an applied course covering extensions of the input?output approach to energy, environmental, and other contemporary policy issues of the time in that same regional science program at Penn in the early 1970s, and by the end of that decade the need for a comprehensive and up-to-date textbook became apparent to us. So the first edition of this book very much reflected our shared experiences with students (primarily graduate or undergraduate submatriculants) in mostly regional science and public policy courses at Penn during the 1960s and 1970s. In addition to the basics (?foundations?), many of the additional topics we included (?extensions?) reflected our research interests at that time ? interregional feedbacks for one of us, energy and environmental applications for the other and spatial aggregation in many-region models as a joint interest. Over the past decade or so it became increasingly and abundantly clear that the time was ripe for an update/revision. We began to take this notion seriously around 2000?2001 ? almost an additional 25 years further into the input?output timeline, so xxix xxx Preface the subject was essentially twice as old as when we wrote the first edition. Activity in the field during that quarter century seems to have exploded. For example: ? The International Input?Output Association (IIOA) was founded (1988). ? The IIOA?s journal, Economic Systems Research, began publication (1989). ? International conferences were held with increasing frequency and drawing increasing numbers of participants (summarized at the end of Appendix C) and starting recently, ?intermediate? input?output meetings are held in nonconference years, co-organized by the IIOA. ? In 1998 Heinz Kurz, Erik Dietzenbacher and Christian Lager published an edited three-volume set of almost 1,500 pages that reproduces some 85 significant input? output papers, along with extensive and detailed introductions to each of the volumes (Kurz, Dietzenbacher and Lager, 1998). These activities are in part a reflection of enormous increases in computer speed and capacity since the 1950s. The net result is that there is now considerable new material to be examined, digested and considered for inclusion and explanation. Accordingly, around the end of 2000 we communicated with about 30 of our input? output colleagues throughout the world, asking for help in finding our way through this maze of material. We listed some new topics that we thought should be included (e.g., social accounting matrices or SAMs), some that we might emphasize more (e.g., commodity-by-industry models), some less (e.g., detailed numerical interregional or multiregional examples), and we asked for reactions and suggestions. Additionally, we took into account what we knew of the uses to which the first edition had been put, e.g., as a text for teaching purposes or desk reference for practitioners and researchers. As a result, we have added some discussion of: ? SAMs (and extended input?output models) and their connection to input?output data; ? Structural decomposition analysis (SDA); ? Multiplier decompositions [Miyazawa, additive (Stone), multiplicative (Pyatt and Round)]; ? Identifying important coefficients; ? International input?output models. We have expanded discussions of: ? The historical background and context for Leontief?s work; ? The connection of input?output accounts and national income and product accounts (NIPAs); ? Commodity-by-industry accounting and models; ? Multipliers, including Miyazawa multipliers, net multipliers, elasticity measures, and output-to-output multipliers; ? Location quotients and related techniques for estimating regional technology, including numerical examples and real-world illustrations; ? Energy input?output analysis to include references to econometric extensions; Preface xxxi ? Environmental applications to include linear programming and multiobjective programming extensions; ? The hypothetical extraction approach to linkage analysis; ? The Ghosh (supply-side) model; ? The Leontief price model; ? Estimating interregional flows; ? Hybrid methods; ? Mixed exogenous/endogenous models. In order to keep the new edition to manageable length, there are topics that had to be excluded or treated only very briefly; these include: ? Econometric/input?output model connections; ? Qualitative input?output analysis; ? Recent developments in dynamic input?output modeling; ? Discussions and comparisons of alternative working models (e.g., REMI and IMPLAN in the USA and others elsewhere); ? The role and interpretation of eigenvectors and eigenvalues in input?output models. The historical material on US input?output data has been reworked and updated, especially to reflect the international movement toward commodity-by-industry formulations. With the ready accessibility of computing capabilities, we have greatly expanded the end-of-chapter problems to include many more realistic examples as well as some real-world examples and applications. Because of the higher level of mathematical competence that we see in our potential readers as compared with 20+ years ago, we have tried to use more compact matrix representations more extensively and whenever possible. With appreciation we acknowledge many helpful conversations, face-to-face and electronic, with Takahiro Akita, William Beyers, Faye Duchin, Geoffrey Hewings, Takeo Ihara, Andrew Isserman, Randall Jackson, Louis de Mesnard, Jan Oosterhaven, Karen Polenske, Jeffery Round and Guy West. Anne Carter and Joseph Richter helped us fill in the historical record of IIOA meetings. Sandra Svaljek and Ivan Rusan at The Institute of Economics, Zagreb, Croatia, kindly supplied us with a copy of Mijo Sekulic?s important 1968 article in ? Ekonomska Analiza, a publication of their Institute. We are grateful to IDE/JETRO (Tokyo), especially Satoshi Inomata, who provided us with many of their important input?output tables and studies using those tables and to leadership and staff of the US Department of Commerce, Bureau of EconomicAnalysis, especially Mark Planting, who helped us navigate the US input?output tables. Finally, we single out two colleagues with whom we have had almost continuous interaction for years: Erik Dietzenbacher, with whom we have had literally hundreds of discussions and from whom we have had as many suggestions, and Michael Lahr who has been a constant source of critical observations and has recommended and helped us track down countless important references.
