The long-run aggregate supply curve can be shifted, when the factors of production change in quantity. For example, if there is an increase in the number of available workers or labor hours in the long run, the aggregate supply curve will shift outward it is assumed the labor market is always in equilibrium and everyone in the workforce is employed.
Similarly, changes in technology can shift the curve by changing the potential output from the same amount of inputs in the long-term. For the short-run aggregate supply, the quantity supplied increases as the price rises. The AS curve is drawn given some nominal variable, such as the nominal wage rate. In the short run, the nominal wage rate is taken as fixed. Therefore, rising P implies higher profits that justify expansion of output. However, in the long run, the nominal wage rate varies with economic conditions high unemployment leads to falling nominal wages — and vice-versa.
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. Recognize the role of capital in the shape and movement of the short-run and long-run aggregate supply curve.
In economics, the short-run is the period when general price level, contractual wages, and expectations do not fully adjust. In contrast, the long-run is the period when the previously mentioned variables adjust fully to the state of the economy. Aggregate supply is the total amount of goods and services that firms are willing to sell at a given price level.
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. During the short-run, firms possess one fixed factor of production usually capital.
It is possible for the curve to shift outward in the short-run, which results in increased output and real GDP at a given price. In the short-run, there is a positive relationship between the price level and the output. The short-run aggregate supply curve is an upward slope. The short-run is when all production occurs in real time. Aggregate Supply : This graph shows the relationship between aggregate supply and aggregate demand in the short-run. The curve is upward sloping and shows a positive correlation between the price level and output.
In the long-run only capital, labor, and technology impact the aggregate supply curve because at this point everything in the economy is assumed to be used optimally. The long-run supply curve is static and shifts the slowest of all three ranges of the supply curve.
The long-run is a planning and implementation stage. In the short-run, the price level of the economy is sticky or fixed depending on changes in aggregate supply.
Also, capital is not fully mobile between sectors. In the long-run, the price level for the economy is completely flexible in regards to shifts in aggregate supply.
There is also full mobility of labor and capital between sectors of the economy. The aggregate supply moves from short-run to long-run when enough time passes such that no factors are fixed. The key question is: Why? Why does the short-run aggregate supply curve have a positive slope? While the general reason is similar to that of market supply curves--the opportunity cost of production--three specific reasons are at work: Inflexible resource prices that often makes it easier to reduce aggregate real production and resource employment when the price level falls.
The pool of natural unemployment , consisting of frictional and structural unemployment, that can be used temporarily to increase aggregate real production when the price level rises Imbalances in the purchasing power of resource prices that can temporarily entice resource owners to produce more or less aggregate real production than they would at full employment. Check Out These Related Terms Once these input providers realize that the cost of living has increased, they will increase the prices that they charge for their input goods and services in proportion to the increase in the price level for final goods.
These contracts usually include a certain allowance for an increase in the price level, called a cost of living adjustment COLA. The COLA, however, is based on expectations of the future price level that may turn out to be wrong.
Depending on the terms of the contract, the workers may not have the opportunity to correct their mistaken estimates of inflation until the contract expires.
In this case, their wage increases will lag behind the increases in the price level for some time. The higher the price level, the more these sellers will be willing to supply.
The result is that the quantity of real GDP supplied by all sellers in the economy is independent of changes in the price level.
