1.1 Overview
As computing speed has increased, applied econometric analysis has significantly expanded its scope and scale. Analysis that only 20 years ago was infeasible can now be completed in the blink of an eye. These developments have helped to shape economics as an empirical science. Modern analysts have a multitude of tools at their disposal, and SAS remains the first choice for many in research, academia, and the business analytics sector. SAS has a number of important advantages. First and foremost, it is thoroughly tested and validated for critical applications. It is fast, with many procedures being optimized for multi-threaded applications. SAS offers extraordinary technical support. Finally, SAS is robust, is flexible, and can be easily adapted to any application.
The examples contained in this volume represent a wide variety of applications that we have covered in over 25 years of teaching. Weve used SAS in graduate teaching at four universities (North Carolina State, Ohio State, Kansas State, and Virginia Tech) and have had the pleasure of training hundreds of graduate students in its use and application. The examples included in this volume were collected from doctoral classes in demand analysis, production analysis, risk modeling, and microeconometrics. The examples are intended to illustrate an approach to applied analysis that can easily be modified to fit general problems of interest encountered by applied practitioners. They may be easily altered for application in any software environment or through the SAS OnDemand for Academics.
