Abstract

Economic growth, minimum wage, and inflation directly shape public purchasing power, as they determine people’s ability to afford daily needs and raise welfare. This study examines their short‑run and long‑run effects, plus the adjustment mechanism, on purchasing power in Indonesia for 2015–2024. Using quarterly secondary time‑series data, analysis applies the ARDL approach and ECM. Results confirm a long‑run cointegrating link between variables. In the long run, economic growth significantly boosts purchasing power, minimum wage has no significant effect, while inflation significantly reduces it. The ECT value of −0.767400 (p < 0.01) shows 76.74% of short‑run deviations are corrected toward long‑run equilibrium each period. These findings emphasize the importance of inclusive growth policies, controlling inflation, and setting minimum wages that are in line with productivity and people's living needs. Coordination of fiscal, monetary and employment policies is needed so that increases in nominal income are truly translated into sustainable and equitable strengthening of people's purchasing power.
