THE MULTIPLIER EFFECT OF PUBLIC INFRASTRUCTURE SPENDING: AN ECONOMETRIC ANALYSIS OF UNION BUDGET ALLOCATIONS ON GDP GROWTH (FY22–FY26)
This paper examines the economic effects of India's strategic shift from FY2022 to FY2026 toward public infrastructure capital expenditures, finding that this asset-creating strategy performs noticeably better than traditional revenue-dominated welfare spending. The study finds a highly efficient total Capex fiscal multiplier of 2.1x using macroeconomic data and a survey of 206 industry specialists, whereas revenue expenditure has a nearly unity fiscal multiplier of 0.98x. With an early absorbent phase impact of 0.8x in Year 1, these economic advantages peak at 1.9x during the construction ramp-up in Year 2, and stabilize at 1.5x in Year 3 as assets are used. Significantly, the PM Gati Shakti initiative's operationalization in Q2-FY24 produced a structural boost that increased the multiplier from 1.8x during the pandemic's recovery to an astounding 2.3x.
The sectors with the biggest economic returns are roads and highways (2.3x), railroads (1.8x), and defense infrastructure (1.2x). The "crowding-in" theory is also strongly supported by the study, as 80.6% of professionals asked agreed that public capital expenditures directly encourage more private investment. Forecasting approaches predict that the ₹10.18 lakh crore infrastructure budget for FY26 would have an aggregate GDP effect of ₹2.2 to ₹2.5 lakh crore over three years, contributing an estimated 1.8% to 2.1% to overall GDP growth. In the end, the results support India's infrastructure-led fiscal strategy's economic soundness and suggest quicker implementation to optimize future gains.
