About IO-Snap

As an extension of their collaborative research efforts at the Regional Research Institute at West Virginia University, Randall Jackson and Christa (Jensen) Court developed the IO-Snap software package to facilitate the use of BEA's input-output data from US national supply and use tables.

In addition to comprehensive economic data provision, IO-Snap is a software application with many analytical features including all aspects of fundamental input-output analyses.  Data can be edited and displayed in a variety of formats and compared and contrasted across geographical definitions at different times.  Cut and paste options are enabled throughout so that users can easily transfer data to spreadsheets for further analysis, graphing, etc. 

Our software supports the generation of Supply and Use Tables for the US, for states, for groups of states, and for generic regions defined by user input-data.  In the process of assembling the various utilities that support national and state-level input-output analysis, we also have created an environment that facilitates inter-state comparisons of input-output related variables such as employment and compensation.

IO-Snap is also built with data manipulation capabilities so that users are free to edit the data, which is an essential feature for building many types of regional models. IO-Snap is designed to provide users with maximum flexibility in modifying and manipulating national and regional IO data.


Dr. Randall Jackson has nearly three decades of national and regional input-output research and applications experience, and is among the nation’s foremost input-output modeling experts. He has published dozens of input-output articles in refereed journals, including the first formalized method for regionalizing U.S. national commodity industry accounts in Economic Systems Research in 1998.

In January of 2002, Randy joined the West Virginia University faculty as Regional Research Institute Director and Professor of Geology and Geography, following previous appointments in the Geography department and Center for Governmental Studies at Northern Illinois University and the department of Geography at The Ohio State University. While at OSU, he also served two years as Associate Director for Research Computing.

Randy’s research interests center on regional economic development with topics ranging from regional economic development strategies through the refinement and reformulation of regional economic modeling frameworks to interregional trade and conjoined macroeconomic energy and environmental modeling. He has been involved in a wide variety of funded research projects with support from a variety of sources including National Science Foundation, the US Departments of Commerce, Energy and Agriculture, the Appalachian Regional Commission, and the Arthur P. Sloan Foundation.

Randy has published in a wide range of academic journals, and serves or served on the editorial boards of the Journal of Regional Science, International Regional Science Review, Letters in Spatial and Resource Sciences, the Australasian Journal of Regional Studies, The Professional Geographer, Geographical Analysis, and Papers in Regional Science. He has participated on NSF review panels, is Immediate Past President of the Southern Regional Science Association, and is on the Western Regional Science Association Board of Directors . He was the 2006-2007 Chair of the North American Regional Science Council, and in 2007 received the David E. Boyce Award for distinguished service to the Regional Science Association International, where he served as the editor of the Association’s Newsletter and established and maintained its primary Internet web site. He holds Adjunct Professorships in Economics and Resource Economics at WVU, Geography at The Ohio State University and Economics at the University of Pittsburgh, and he consults privately through his company, EconAlyze LLC.


Dr. Christa (Jensen) Court has been involved in numerous funded projects involving input-output analysis and impacts assessments over the last decade and has a growing list of related publications. She has undergraduate degrees in Economics and Spanish from Middle Tennessee State University and a Masters and Ph.D. in Economics from West Virginia University. During her time at West Virginia University, Christa held the position of Graduate Research Fellow at the Regional Research Institute.

Currently, Christa is a Staff Scientist at MRIGlobal, an independent, not-for-profit research institute that specializes in innovation, technical excellence, and problem solving across the full spectrum of research and development. She also holds the position of Industry Liaison at the Regional Research Institute.
