TAILIEUCHUNG - An Assessment of the Economic Impact of the Rosemont Copper Project on Pima County, Arizona using the IMPLAN Regional Economic Forecasting Model

The population is continuing firms in these time periods. Since we cannot distinguish organic from acquired growth, we study total growth. In order to relate to previous literature, we use employment and sales as growth indicators, yet in addition we introduce productivity and value added. 7 Productivity growth is defined as growth in value-added based labor productivity, which is the single most frequently used productivity statistic (OECD, 2001 p. 12). Labor productivity is a key determinant of living standards and of significant policy relevance, and also a good starting point for productivity analysis, which later can be extended to multifactor productivity. | An Assessment of the Economic Impact of the Rosemont Copper Project on Pima County Arizona using the IMPLAN Regional Economic Forecasting Model May 2012 L. William Seidman Research Institute W. P. Carey School of Business Arizona State University Executive Summary This report measures the economic impact of the Rosemont Copper Project on employment labor income output gross regional product and tax revenue in Pima County Arizona during the project s construction production and post-production phases which span a period of 27 years. Estimated impacts include both the direct effects of Rosemont Copper Project operations and multiplier effects that arise when income is recycled within the county s economy. The IMPLAN input-output model was used to estimate multiplier effects. Economic Impacts during the Construction Phase The construction phase will last 4 years with the last year of construction overlapping with the first year of production. Local construction expenditures will be 576 million and total economic impacts shown in Table 1 amount to 983 million in output 8 376 person-years of employment 382 million in labor income and 506 million in gross regional product. Economic Impacts during the Production and Post-Production Phase The production phase will last 21 years followed by a post-production phase of 3 years. Table 1 summarizes the total impacts and provides a breakdown of direct and indirect effects detailed figures are discussed in sections 3 and 4. The total impact of the Rosemont Copper Project over the duration of the production and post-production phases on the economy of Pima County is estimated to be 41 501 person-years of employment gross regional product of billion output of 20 511 million and labor income of billion. Annual average impacts - calculated over the 21-year period of full production- will be 1 784 jobs 260 million of gross regional product output of 923 million and labor income of 100 million. 2 Table 1 Rosemont Copper Project
