Economic impact analyses were conducted on waterfowl hunting and the logging industry in Mississippi to determine the validity of the Impact Analysis for Planning (IMPLAN) input-output software model and associated 2007 databases. Detailed expenditure profiles were collected separately for the two studies through mail, electronic, and face-toace surveys and analyzed with separate models using default data within IMPLAN itself. Additionally, for the logging industry, total economic impacts (i.e., direct, indirect, induced) were estimated within the IMPLAN model by removing the total employment for the relevant sector and calculating the impact on the state economy. This procedure was recommended by Minnesota IMPLAN Group, Incorporated (MIG, Inc.). Economic impact results derived from replicating this method were first compared to economic impact results derived with a population size of (N=2,471) loggers and second, with a sample size of (n=33) loggers. The top 20 output sectors in the state economy from both waterfowl hunting and logging expenditures were determined from model results. In turn, new data were acquired and used in each model that was more localized to the state, to replace one, two, three, and four of the top 20 sectors of importance for each industry, respectively. Multiple IMPLAN models were then reconstructed to determine economic outputs. The Mississippi default models and survey-based data default models, and survey-based data replacement models were compared, and differences in total economic outputs derived. Results using sector changes yielded different results for both industries in comparison to default values used within the model, making the case that the IMPLAN model has the potential to both understate and overstate economic impacts to Mississippi or any state economy for recreation and industry activity.
