This book is an introduction to the use of probability models for analyzing risks and economic decisions. Throughout this book, author Roger Myerson focuses on showing students how to use probability in complex realistic situations. All the analytical work in this book is done in Microsoft Excel spreadsheets. As a result of the emphasis on spreadsheet modeling, students will also develop sophisticated spreadsheet skills. However, the main goals of the book are to make the practical power of probability analysis accessible to students and to demonstrate how to apply these concepts in the real world.

About the Author:

Roger B. Myerson is the W. C. Norby Professor of Economics at the University of Chicago. He previously taught at the Kellogg School of Management at Northwestern University (1976-2001). His teaching interests include decision analysis, probability modeling, game theory, mathematical optimization theory, social choice and formal political theory, and economics of information. Dr. Myerson has received a number of professional awards, including Guggenheim Fellow (1983-1984), Sloan Foundation Fellow (1984-1986), Fellow of the Econometric Society (elected 1983), Fellow of the American Academy of Arts and Sciences (elected 1993), and an honorary doctorate from the University of Basel (2002). His research interests include game theory, economics of information, and analysis of voting systems.
