How does MGM2 differ from MGM?
MGM2 is a multi-page Excel spreadsheet that provides considerably more detail and flexibility than MGM. The MGM2 model disaggregates the analysis to handle distinct subgroups of visitors (segments), itemizes spending by segment within 12 spending categories, and uses sector-specific multipliers derived from IMPLAN models for regions around National Park units. Default spending data for park visitors and multipliers for regions around parks are built into the model. Uses may choose from sets of defaults, adjust these to fit a particular application, or enter their own spending data. The original MGM model was used primarily to estimate overall impact of all visitors to a particular park. MGM2 can also be used to evaluate specific management and policy decisions. To do so, you must estimate the change in the number and types of visitors resulting from a particular action. You may also enter all park visitors in MGM2 to obtain overall park visitor spending impacts.
