The book has been written to conform to the syllabi requirement of the Indian technical universities. It meets the needs of engineering students who have to consider and evaluate economic and financial aspects of alternatives before them. Relevant accounting and economic concepts and their use have been explained in precise, adequate and easily comprehensible manner. Each topic covered in it is self-contained and obviates the need for additional reading. There are a large number of solved illustrative examples as also addenda of learning objectives, key words and review questions. Since an engineering economist uses several conversion factors involving time placements, an appendix has been provided explaining the symbols representing these conversion factors, the formulas used for calculating them, together with some illustrative tables.
