Developed at WVU by Randall Jackson and Christa (Jensen) Court; the IO-Snap software package facilitates the use of BEA's input-output data from US national supply and use tables, and supports the generation and use of regional input-output accounts. In addition to comprehensive economic data, IO-Snap provides a wide range of analytical tools.  Data can be edited and displayed in a variety of formats and compared and contrasted across geographical definitions at different times. The software supports the generation and display of supply, use, direct requirements, indirect requirements, gross product, and other data 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 users are free to edit the data, which is an essential feature for building many types of regional models. This workshop is designed to showcase many of the new features of IO-Snap and introduce potential users to the program. Participants are encouraged to download the software ahead of time, and to bring their laptops to the workshop.  The software and example data also can be obtained at the workshop.
