Long-run aggregate supply (LRAS) — Over the long run, only capital, labour, and technology affect the LRAS in the macroeconomic model because at this point everything in the economy is assumed to be used optimally. In most situations, the LRAS is viewed as static because it shifts the slowest of the three.
[5]: 266 Under the premise that the price level is flexible in the long run, but sticky or even completely fixed under shorter time horizons, it is usual to distinguish between a long-run and a short-run aggregate supply curve. Whereas the long-run aggregate supply curve (LRAS) is vertical, the short-run aggregate supply curve will have a ...
The transition from the short-run to the long-run may be done by considering some short-run equilibrium that is also a long-run equilibrium as to supply and demand, then comparing that state against a new short-run and long-run equilibrium state from a change that disturbs equilibrium, say in the sales-tax rate, tracing out the short-run ...
One benefit of a supply-side policy is that shifting the aggregate supply curve outward means prices can be lowered along with expanding output and employment. This is in contrast to demand-side policies (e.g., higher government spending), which even if successful tend to create inflationary pressures (i.e., raise the aggregate price level) as ...
Economists distinguish between short-run and long-run supply curve. Short run refers to a time period during which one or more inputs are fixed (typically physical capital), and the number of firms in the industry is also fixed (if it is a market supply curve). Long run refers to a time period during which new firms enter or existing firms exit ...

In the short run, an economy-wide negative supply shock will shift the aggregate supply curve leftward, decreasing the output and increasing the price level. [1] For example, the imposition of an embargo on trade in oil would cause an adverse supply shock, since oil is a key factor of production for a wide variety of goods.
