This is afree pdf download of the entire book. As the author, I own the copyright. Amazon markets bound print copiesof the book at at a nominal price for classroom use.

The book contains acomprehensive treatment of the traditional agricultural production economics topics employing both detailedgraphics and differential calculus. The text focuses on the neoclassical factor-product, factor-factor and productproduct models, and is suitable for an advanced undergraduate or a beginning graduate-level course in staticproduction economics. Chapters also deal with linear programming, risk and uncertainty and intertemporalresource allocation. A basic knowledge of differential calculus is assumed. Individual chapters are largely selfcontained, and the book is suitable for instruction at a variety of levels depending on the specific needs of theinstructor and the mathematics background of the students.This is one of three agricultural economics textbooks by David L. Debertin. A companion 100-page color bookAgricultural Production Economics (The Art of Production Theory) is also a free download. A bound print copyis also available on at a nominal cost under the following ISBN numbers:ISBN- 13: 978-1470129262ISBN- 10: 1470129264The third book is aimed at upper-division undergraduate students of microeconomics in agricultural economicsand economics. It is a 242-page book titled Applied Microeconomics (Consumption, Production and Markets)and is a free download. Bound print copies are also available at and through college bookstores ata nominal cost under the following ISBN numbers:ISBN‐13: 978‐1475244342ISBN-10: 1475244347This book Applied Microeconomics is much newer than Agricultural Production Economics, having beencompleted in 2012. As the author, I would suggest downloading and studying this Applied Microeconomicsbook before diving into Agricultural Production Economics. This book uses spreadsheets to calculate numbersand draw graphs. Many of the examples and numbers are the same ones used in Agricultural ProductionEconomics, so the two books are tied to each other.

David L. Debertin is Professor Emeritus of Agricultural Economics at the University of Kentucky, Lexington,Kentucky and has been on the University of Kentucky Agricultural Economics faculty since 1974 with aspecialization in agricultural production and community resource economics. He received a B.S. and an from North Dakota State University, and completed a Ph.D. in Agricultural Economics at PurdueUniversity in 1973. He has taught the introductory graduate-level course in agricultural production economicsin each year he has been at the University of Kentucky. The first edition of Agricultural Production economicswas published in hardback by Macmillan in 1986. He began work on the second edition of the book after theMacmillan edition went out of print in 1992, taking advantage of emerging two-and three-dimensionalcomputer graphics technologies by linking these to the calculus of the modern theory of production economics.The book has been edited and revised each year since 1992. All diagrams and figures benefit from improvedcomputer technology since the first edition was written. The current edition also includes two chapters oncontemporary production theory that were not part of the first edition.
