Key Concepts

Long-run Aggregate Supply (LRAS)

LRAS represents the economy's potential output when all resources are fully employed. It is determined by the quantity and quality of factors of production such as labor, capital, and technology, and it remains unchanged by fluctuations in the overall price level in the long term.

Labor Force Growth

An increase in the labor force, such as through immigration, expands the pool of available workers. This growth in human capital enhances the economy's productive capacity, shifting the LRAS curve to the right as there is more labor available to produce goods and services.

Technological Change

Technological advancements improve the efficiency and productivity of both labor and capital. Innovations, like the development of a more powerful computer chip, enable higher output without necessarily increasing input quantities, thereby shifting the LRAS curve to the right.

Capital Stock Destruction

Events that damage or deplete physical capital, such as a severe hurricane damaging factories, reduce the economy's capacity to produce. This loss of infrastructure or capital shifts the LRAS curve to the left, indicating a decline in long-term productive capacity.

Policy and Regulation Effects in the Long Run

While changes in wage policies, such as a minimum wage increase, might affect production costs in the short run, over the long run, prices and wages adjust fully. Therefore, such regulatory changes typically do not alter the economy's underlying productive capacity or shift the LRAS.
