This analysis evaluates the effect of a proposed project on the Texas economy from 2026 to 2033. It applies two policy variables: an increase of 250 construction jobs per year from 2026 through 2028, measured by place of work, followed by a sustained increase of 450 units of machinery manufacturing output annually from 2029 through 2033.
The run tests how a short-term expansion in construction employment, followed by a medium-term increase in manufacturing output, moves labor markets and industrial linkages across the state. Because the REMI PI+ engine is dynamic, every figure below is a difference from the model’s own Texas baseline in that year, not a one-off multiplier applied to a headline number.

Employment in individuals (jobs). Output and GDP in millions of fixed local (2024) dollars. Personal income is reported by the model in thousands of current dollars and is shown here in millions. All results are differences from REMI baseline values for a hypothetical scenario.
