Thus, there is an abundance of un-utilised or under-utilised resources. Should there be an increase in aggregate demand, the spare capacity will allow producers to increase output production easily without incurring high costs. Hence, there is no pressure on the general price level to increase. In the long run, prices do not keep rising. The AS curve is simply perfectly price-inelastic i. This is also called the classical range of the AS curve.
In the LR, all firms in the economy reach their full employment level i. Price levels are fully flexible as all firms will make adjustments to their prices in response to changes in demand.
The "short run" here essentially corresponds to your so-called "very short run". The "long run" here is the same as yours.

Also, as wages are assumed to be static in the short run, increases in labor only result in increased quantity, but not price. This is why the SRAS curve is almost horizontal at this stage. However, similar to the SRAS curve, wages can be changed although not quickly.
It is assumed that it takes time to give workers a pay raise. This is known as sticky wages. The third and final stage of the aggregate supply curve is known as the long run aggregate supply curve LRAS.
In the long run, it is assumed that labor, wages and capital are all controllable. Furthermore, technological improvements are inevitable in the long run. Technology has the effect of increasing levels of production while holding labor and capital constant. This is because increased technology makes the production process more efficient.
When the curve shifts to the left, the price level increases and the GDP decreases. Any event that results in a change of production costs shifts the short-run supply curve outwards or inwards if the production costs are decreased or increased.
Factors that impact and shift the short-run curve are taxes and subsides, price of labor wages , and the price of raw materials. Changes in the quantity and quality of labor and capital also influence the short-run aggregate supply curve. In regards to aggregate supply, increases or decreases in the price level and output cause the aggregate supply curve to shift in the short-run.
Privacy Policy. Skip to main content. Aggregate Demand and Supply. Search for:. Aggregate Supply. Introducing Aggregate Supply Aggregate supply is the total supply of goods and services that firms in a national economy plan to sell during a specific time period. Learning Objectives Define Aggregate Supply. Key Takeaways Key Points Aggregate supply is the relationship between the price level and the production of the economy. Key Terms factor of production : A resource employed to produce goods and services, such as labor, land, and capital.
Learning Objectives Summarize the characteristics of short-run aggregate supply. In the short-run, the nominal wage rate is fixed. As a result, an increasing price indicates higher profits that justify the expansion of output.
The AS curve increases because some nominal input prices are fixed in the short-run and as output rises, more production processes encounter bottlenecks. In the short-run, the production can be increased without much diminishing returns.
The average price level does not have to rise much in order to justify increased production. In this case, the AS curve is flat. When demand is high, there are few production processes that have unemployed fixed outputs. Any increase in demand production causes the prices to increase which results in a steep or vertical AS curve.
Key Terms supply : The amount of some product that producers are willing and able to sell at a given price, all other factors being held constant.
The Slope of the Long-Run Aggregate Supply Curve The long-run aggregate supply curve is perfectly vertical; changes in aggregate demand only cause a temporary change in total output. Learning Objectives Assess factors that influence the shape and movement of the long run aggregate supply curve. Key Takeaways Key Points The long-run is a planning and implementation phase. It is the conceptual time period in which there are no fixed factors of production.
Aggregate supply is usually inadequate to supply ample opportunity. Often, this is fixed capital equipment. In the long run, the nominal wage rate varies with economic conditions high unemployment leads to falling nominal wages — and vice-versa.
Key Terms long-run : The conceptual time period in which there are no fixed factors of production. Moving from Short-Run to Long-Run In the short-run, the price level of the economy is sticky or fixed; in the long-run, the price level for the economy is completely flexible. Learning Objectives Recognize the role of capital in the shape and movement of the short-run and long-run aggregate supply curve.
Key Takeaways Key Points When capital increases, the aggregate supply curve will shift to the right, prices will drop, and the quantity of the good or service will increase. Aggregate supply moves from short-run to long-run by considering some equilibrium that is the same for both short and long-run when analyzing supply and demand. That state of equilibrium is then compared to the new short-run and long-run equilibrium state from a change that disturbs equilibrium.
Key Terms capital : Already-produced durable goods available for use as a factor of production, such as steam shovels equipment and office buildings structures.
Reasons for and Consequences of Shifts in the Short-Run Aggregate Supply Curve The short-run aggregate supply shifts in relation to changes in price level and production.
