INPUT OUTPUT ANALYSIS
for PRACTITIONERS
Version 1.0.1 (IOW) is an elegant and easy to use input output table manipulation Windows application with a wide array of capabilities. IOW is a menu driven input output modeling system, written in the C++ programming language specifically for Windows based machines. The package implements nearly every method described in Input Output Analysis, Foundations and Extensions, by Ron Miller and Peter Blair (Prentice Hall, Englewood Cliffs, N.J., 1985), and much more. In addition to providing single region analysis capabilities, IOW supports the analysis of interregional systems.

Analysts with input output tables generated by IMPLAN or other models have full access to IOW, which will import or export tables in ASCII or Lotus format. Industry sectors and regions can be inserted, rearranged, deleted, aggregated, and subtracted from one another.

Tables can be printed to screen, file or printer, and the program includes a print and screen display setup facility. Tables can be displayed in coefficient or transaction format, and gross product accounts can be generated and printed or displayed easily.

IOW also has extensive table editing capabilities. Values and labels can be changed easily. Blocks can be moved, copied or erased, and rows or columns of transactions values can be uniformly increased or decreased. There is a table balancing facility and the RAS bi proportional adjustment method, complete with the ability to constrain selected values, is easily implemented.

Of course IOW also supports multiplier analyses, final demand impacts assessments, and linkage analysis, as well as an implementation of inverse sensitivity analysis. IOW provides the ability to perform nearly every function that analysts and practitioners use. The program was written by Guy R. West, of the University of Queensland, Australia, to support a variety of private and public sector applications. IOW is distributed with an extensive Help capability.

The Complimentary Version of IOW supports models with up to 30 rows and columns. At present, there is no commercial counterpart or version to accommodate larger models, although a professional version is anticipated. This version is seen as an ideal instructional tool.

This version of IOW is distributed free of charge along with a Demo table. There is no technical or user support. There are no warrantees expressed, written or implied.
