dock going on to lakeTotal economic contributions were estimated using a regional economic model constructed with licensed IMPLAN© software (Version 3) and associated 2015 Florida county datasets ( IMPLAN© is an input–output/social accounting matrix modeling system. Input–output analysis is a standard, transparent technique for estimating the broad economic impacts resulting from changes in specific economic activities in a regional economy (Miller and Blair 2009). These economic models account for the transactions between industries, governments, employees, and households and provide detailed estimates of impacts on the regional economy from changes in final demand, which is the value of goods and services produced and sold to users (institutions) during the calendar year. Impacts can be defined in terms of a variety of economic variables including:

Regional economic models enable the estimation of economic multipliers that measure the total changes in an economy resulting from a given change in direct output, income, or employment. Economic multipliers incorporated in the regional economic model can measure the estimated total contribution to the regional economy for an industry of interest. Multipliers are comprised of direct, indirect, and induced components:

In this case, the study region was defined as the state of Florida. Data from IMPLAN© used to model contributions in this report represent the economic structure of the Florida economy in 2015. The model was constructed with social accounts for households, governments (state/local and federal), and capital investment internalized. This analysis used the Trade Flows specification of the IMPLAN© model customized to avoid double-counting of direct impacts, consistent with best practice for economic contribution analysis (Henderson et al., 2017; Joshi et al. 2017).

The forest industry sectors used in this analysis are described according to the North American Industry Classification System (NAICS) code corresponding to each IMPLAN© industry sector, as shown below.

Inputs to the IMPLAN© model for sector-level analysis of the Florida forest industry are summarized in the table below. For most industry sectors, the annual average of direct employment in 2016 from the Quarterly Census of Employment and Wages was entered in the IMPLAN© model. Stumpage values were used for private, state, and federal forestry production sectors. For the pulp mill and logging sectors, employment information from the IMPLAN© database (2015) were used. The number of employees in wood and gum chemicals and biomass electricity generation were taken from the Hoovers/Dunn and Bradstreet database. The IMPLAN© software automatically imputed industry sales for the employment numbers entered based on the industry average output per employee ratios. The software also applied industry-specific deflators to express output in model year (2015) values, then reinflated the resulting impact estimates to express in current year (2016) dollars. For the Wholesale Trade sector used to represent lumber and wood wholesalers, a trade margin of 17.7 percent was applied to the imputed industry sales. For recreational visitor retail purchases, trade margins were applied to purchases at gasoline stores and sporting goods stores. Only the export share of industry output was considered as new final demand for which we account for the indirect and induced contributions, in keeping with best practice for economic contribution analysis (Watson et al, 2007).



Total economic contributions were calculated for each major industry group: forestry production, primary wood products, secondary wood products, primary paper products, converted paper products, forest chemical products manufacturing, allied manufacturing, wholesale trade in lumber and wood products, and biomass electric power generation. Total economic contributions were also estimated for forest-based nonresident visitor spending. State-level results were allocated to individual counties in proportion to timber removals for forestry production and in proportion to direct employment in all other industry groups. Results for individual Florida counties were aggregated to analyze results for the nine functional economic regions in Florida, as defined by the U.S. Department of Commerce’s Bureau of Economic Analysis (Johnson and Kort, 2004). County level results were also aggregated to analyze results for categories along the Urban-Rural Continuum, as defined by the U.S. Department of Agriculture’s Economic Research Service.
