MI-REC: Micro-Implan Receation Economic Impact Estimation System

The MI-REC system consists of a set of utilities and customized procedures for estimating the economic impacts of recreation and tourism projects. MI-REC is designed to be used with Micro-IMPLAN , a regional economic modeling system developed by the USDA Forest Service. MI-REC will help you to

More Information about MI-REC

The MI-REC system was developed to assist planners, researchers, and economic analysts in assessing the local and regional economic impacts of actions affecting recreation and tourism activity. Assessing the impacts of changes in recreation and tourism activity in a region is complicated by the lack of clearly defined recreation and tourism sectors, and the difficulties in obtaining suitable estimates of recreation and tourism spending in a given area. The MI-REC system helps facilitate the use of IMPLAN for recreation and tourism applications by providing spreadsheets for estimating recreation spending along with utilities for bridging these spending estimates into the IMPLAN system.

The MI-REC system was initially developed to evaluate economic impacts associated with water-based recreation at U.S. Army Corps of Engineers facilities throughout the country. Two major spending surveys sponsored by the U.S. Army Corps of Engineers, provide recreation spending profiles for a variety of recreation and tourism market segments. The initial use of the MI-REC system has been to apply the results of national and regional recreation spending surveys to sub-regional and local problems. The system has, however, been developed with more general recreation and tourism applications in mind. Other recreation & tourism spending data may be imported into the MI-REC spreadsheet programs and we continue to extend the spending databases and supporting software for a broader range of applications.

The MI-REC spreadsheets produce estimates of the total spending changes associated with actions affecting recreation and tourism activity in an area. The impacts of these changes on the regional economy, estimated using IMPLAN, may be expressed in terms of sales/output, income, value added, or employment. Using input-output models for a local region, direct, indirect, induced and total effects may be estimated. Impacts may be examined by visitor segments and for particular economic sectors. Procedures and data files for assessing impacts of both trip and durable goods spending have been developed.

The principal advantages of the MI-REC/IMPLAN system are:

(1) It is tailored to recreation/tourism applications

(2) Default spending data and procedures for estimating spending changes are provided. Where local data is available, it can be used.

(3) Input-output models and multipliers can be estimated for any multi-county region.

(4) Procedures for estimating input-output models and bridging recreation spending data to input-output models are greatly simplified for analysts with limited regional economic modeling skills.

(5) The system accommodates varying levels of detail and customization, as dictated by the problem and time and skills of the analyst.


Four kinds of files/utility programs are provided in MI-REC. These utilities are designed to work together, with consistent definitions of spending categories and units of analysis across the different programs and data files. The files were separate spreadsheet templates in the original Lotus 1-2-3 version of MI-REC. The new Excel 5.0 version of MI-REC integrates the utilities into a single multi-page spreadsheet notebook.

(1) Recreation/Tourist Spending Estimators. Spreadsheet templates help you to estimate changes in spending using per visit spending profiles for different types of visitors (recreation market segments) and estimates of the number and types of visitors affected by an action. The programs produce spending vectors suitable for use with Micro-IMPLAN's impact analysis procedures. The spreadsheets also can serve as stand-alone utilities to simulate direct spending effects of various actions. Several standardized tables and graphs are provided for summarizing spending effects -- in total, by spending category, and by visitor segment.

(2) Recreation/Tourism Spending Data Sets. A set of visitor spending data sets are provided for use with the spending estimators. These data sets were developed from surveys at water-based recreation facilities. Analysts may use the data sets that are provided, modify these to better fit an intended application, or assemble corresponding data sets from their own visitor surveys and other sources. Additional spending data sets are being generated from recent recreation and travel surveys.

(3) Micro-IMPLAN Utility files. Several customized MI utility files are provided for use with the spending estimators and recreation data sets. These files are used to bridge the recreation spending data into IMPLAN's 528 sectors (MI Activity Database and files) and to aggregate sectors to highlight those most affected by recreation & tourism (MI aggregation templates). Utilities are provided for both trip-related and durable goods spending. The Excel 5.0 version automates the bridging procedures by creating an ASCII file suitable for importing a visitor spending scenario into IMPLAN.

(4) Reporting formats. IMPLAN impact reports may be converted to spreadsheet formats and integrated with data from the spending estimators in a single spreadsheet workbook. Suggested reporting formats and sample interpretations are provided to help in organizing and interpreting the large amount of information produced by Micro-IMPLAN.
