I congratulate Sergio Jara-Diaz on the publication of Transport Economic Theory. This book addresses the fundamental economic questions of how to design and evaluate transportation projects and price transportation services. It is a definitive and concise exposition of the applicable economic theory of resource valuation and allocation, and adds to that theory in the areas of spatial technology and the valuation of benefits from public projectsA". Sergio's book provides a solid theoretical foundation for the principles that, if employed in transportation planning and policy choices, will improve transportation systems and the lives of consumers who use them.A" Daniel L. McFadden, 2000 Nobel Laureate in Economics, University of California, Berkeley. This is a book that is well overdue that finally integrates, in such a poetic way, the important contribution to transport microeconomic theory that Sergio Jara-Diaz has made over the last 25 years. A serious student of transport economics, admittedly one with some appreciation of essential mathematical tools, will find this book essential reading, almost the status of a primer. It is rich in structure and content but, most importantly, flows naturally as the author builds up the theoretical toolkit in economic theories of production, cost, demand, valuation and pricing. The emphasis on space and time is crucial to transport economics and Sergio Jara-Diaz is a master of the craft in developing, demonstrating and convincing everyone of the way in which space and time should be built into the theory of transport economics. It is worth investing time in reading this book, since it will save time in having to wade through the enormous literature in the journals and other books. This book has reset the benchmark in scholarship in transport economicsA". Professor David A. Hensher FASSA, Director, Faculty of Economics and Business, Institute of Transport and Logistics Studies, The University of Sydney.
