How does 'Cost-Push Inflation' fundamentally differ from 'Demand-Pull Inflation' within macroeconomic theory?

💡 Solution & Explanation

Cost-push inflation arises when overall prices increase due to escalating costs of wages and raw materials, shifting the aggregate supply curve leftward. In contrast, demand-pull inflation occurs when aggregate demand for goods and services outpaces aggregate supply, pulling the price level upward. Supply-side shocks, such as spikes in crude oil prices or agricultural failures, frequently trigger cost-push inflation by raising production expenses across multiple industries. Policymakers face severe dilemmas addressing cost-push inflation because contractionary monetary measures cannot directly lower raw material costs or supply bottlenecks. A related economic indicator is the wholesale price index, which tracks primary level price movements of raw commodities.
