The document discusses the economic impacts of the Haynesville Shale in northwest Louisiana. It summarizes previous studies that estimated the effects of shale development on employment, income, tax revenue, and economic indicators using economic models. It then describes the author's regression model and results analyzing the relationship between shale activity and personal income in northwest Louisiana from 1995 to 2014. While some variables like employment and population correlated as expected, the regression found that natural gas production and new wells drilled did not significantly predict total personal income in the region.
