Inflation's Causes and Economic Consequences

Passage

Inflation, broadly defined as the sustained general increase in the price level of goods and services within an economy over time, is one of the most closely monitored and consequential phenomena in macroeconomics, with its causes, measurement, and management remaining subjects of ongoing debate among economists and policymakers. Demand-pull inflation occurs when aggregate demand in an economy outpaces its productive capacity, creating upward pressure on prices as consumers and businesses compete for a limited supply of goods and services, a dynamic commonly associated with periods of rapid economic growth or expansionary fiscal policy. Cost-push inflation, by contrast, originates on the supply side, driven by increases in the costs of production inputs such as energy, raw materials, or labour, which businesses then pass on to consumers through higher prices. The consequences of sustained inflation extend well beyond simple price increases, eroding the real purchasing power of wages and savings, disproportionately harming lower-income households who spend a larger share of their income on essential goods, distorting investment decisions, and undermining confidence in a currency. Central banks in most market economies are therefore mandated to maintain price stability, typically targeting annual inflation rates of approximately two percent, deploying monetary policy tools such as interest rate adjustments to balance the competing demands of controlling inflation and sustaining sufficient economic growth to support employment.
