The author felt during his several years of overseas and Indian teaching experience that students fail to understand the books written on industrial economics because generally they are written in technical language. This book is designed to complement those readings by summarizing all important concepts in one compact volume, rather than burden students with a voluminous text on top of their assigned readings. Since this course is not taught before the Master's degree, the students are not familiar with its vocabulary, methodology and course contents. The author has made an attempt to write it in very non technical language. Students who try to understand the Economics of Industry through self-learning may also find it easy. The target audience for this book includes students, junior researchers, and professors teaching courses on Industrial Economics, although senior researchers can also use this book as a handy and compact reference. This book is useful for those students who offer the Economics of Industry to do the research work at Post Graduation and D.Phil. Level.
