What can cause the long run aggregate supply curve to shift?
The long-run aggregate supply curve can shift only when there are changes in factors that affect the potential output of an economy. Factors that shift the long-run aggregate supply include labor, capital, natural resources, and technology changes. Figure 3. Shifts in LRAS curve, StudySmarter Originals
How can the government increase the long-run aggregate supply?
Improving education increases a labor force’s productivity. Policies that encourage labor participation increase the workforce, thereby increasing the long-run aggregate supply. Entrepreneurs – Governments that provide a hospitable environment for entrepreneurs will increase their long-run aggregate supply.
What is long-run aggregate supply?
Long-run aggregate supply refers to the total amount of production in an economy given that its full resources are employed. Long-term drivers of real GDP are unaffected by price levels; hence the aggregate supply curve is vertical, as seen in Figure 1. As the LRAS is vertical, there is no long-run trade-off between inflation and unemployment.
What happens to aggregate supply and demand at long run equilibrium?
The economy shown here is in long-run equilibrium at the intersection of AD1 with the long-run aggregate supply curve. If aggregate demand increases to AD2, in the short run, both real GDP and the price level rise. If aggregate demand decreases to AD3, in the short run, both real GDP and the price level fall.

What factors affect long run aggregate supply?
Long run aggregate supply (LRAS) The long run aggregate supply curve (LRAS) is determined by all factors of production – size of the workforce, size of capital stock, levels of education and labour productivity.
What causes an increase in aggregate supply?
To correctly understand the aggregate supply curve, time is an essential factor. In the short run, rising prices (ceteris paribus) or higher demand causes an increase in aggregate supply. Producers do this by increasing the utilization of existing resources to meet a higher level of aggregate demand.
Which would increase aggregate supply quizlet?
Which would increase aggregate supply? The economy experiences an increase in the price level and a decrease in real domestic output. Which is a likely explanation? The economy experiences an increase in the price level and an increase in real domestic output.
Which of the following would shift the long-run aggregate supply curve right?
Which of the following would shift the long-run aggregate supply curve right? rising real GDP only. reduces the costs of production, so the aggregate quantity of good and services rises.
What are the determinants of aggregate supply?
The five determinants of supply are factor prices, technology, labor and capital productivity, Government rules, subsidies and taxes, and availability of factors of production. These determinants can shift the aggregate supply curve left or right, causing decrease or increase.
What happens to aggregate supply when the price level rises?
Notice on the graph that as the price level rises, the aggregate supply—quantity of goods and services supplied—rises as well.
How does inflation affect aggregate supply?
When the aggregate supply of goods and services decreases because of an increase in production costs, it results in cost-push inflation. In order to compensate, the increase in costs is passed on to consumers, causing a rise in the general price level: inflation.
What are the three components of aggregate supply?
The main components of AD are:Consumption Demand: It is the total expenses that all the households in an economy are willing to incur on the purchase of goods and services for their personal consumption in a given time period. ... Investment Demand: ... Government Demand: ... Net Export Demand (X-M):
What is the long run aggregate supply?
Long run aggregate supply refers to the total amount of production that takes place in an economy given that its full resources are employed.
What causes the long run aggregate supply curve to shift?
Factors that shift the long-run aggregate supply include labor changes, capital changes, natural resources, and technology changes.
Why is aggregate supply vertical in the long run?
Long-run Aggregate supply curve is vertical because, in the long run, the general level of prices and wages does not impact the economy's capacity...
What are the components of long run aggregate supply?
In the long term, an economy's output of goods and services (its real GDP) relies on its supply of labor, capital, and natural resources and the av...
Briefly explain the classical LRAS.
The classical long-run aggregate supply is vertical, which means that it does not change as the price level changes. The reason for that is that in...
Is there a trade off between inflation and unemployment in the long run?
As the LRAS is vertical it means that there is no long-run trade-off between inflation and unemployment.
Why LRAS corresponds to PPC curve?
The LRAS curve is in line with the production possibilities curve (PPC) as they both represent the maximum sustainable capacity.
What is maximum sustainable capacity?
Maximum sustainable capacity refers to the total amount of production that can take place given that all resources are fully employed.
Explain the difference between the short run and long run aggregate supply.
The aggregate supply curve behaves quite differently in the short term than in the long term. The main difference between short-run and long-run ag...
Why is it important to understand the long run aggregate supply curve?
Because economic growth can be considered as a process in which the long-run aggregate supply curve shifts to the right, and because output tends to remain close to this curve, it is important to gain a deeper understanding of what determines long-run aggregate supply ( LRAS ).
How is the long run aggregate supply curve determined?
The position of the long-run aggregate supply curve is determined by the aggregate production function and the demand and supply curves for labor. A change in any of these will shift the long-run aggregate supply curve.
How does aggregate production affect real wages?
Of course, the aggregate production function and the supply curve of labor can shift together, producing higher real wages at the same time population rises. That has been the experience of most industrialized nations. The increase in real wages in the United States between 1990 and 2007, for example, came during a period in which an increasing population increased the supply of labor. The demand for labor increased by more than the supply, pushing the real wage up. The accompanying Case in Point looks at gains in real wages in the face of technological change, an increase in the stock of capital, and rapid population growth in the United States during the 19th century.
How is GDP determined in the long run?
Our model of long-run aggregate supply tells us that in the long run, real GDP, the natural level of employment, and the real wage are determined by the economy’s production function and by the demand and supply curves for labor. Unless an event shifts the aggregate production function, the demand curve for labor, or the supply curve for labor, it affects neither the natural level of employment nor potential output. Economic growth occurs only if an event shifts the economy’s production function or if there is an increase in the demand for or the supply of labor.
What is aggregate production?
An aggregate production function relates the total output of an economy to the total amount of labor employed in the economy, all other determinants of production (that is, capital, natural resources, and technology) being unchanged. An economy operating on its aggregate production function is producing its potential level of output.
Why does the production function shift up to PF2?
The production function in Panel (b) shifts up to PF2. Because it reflects greater productivity of labor, firms will increase their demand for labor, and the demand curve for labor shifts to D2 in Panel (a). LRAS1 shifts to LRAS2 in Panel (c). Employment and potential output rise. Potential output will be greater than $2,200 billion.
Why is economic growth a rightward shift?
Because economic growth is the process through which the economy’s potential output is increased, we can depict it as a series of rightward shifts in the long-run aggregate supply curve. Notice that with exponential growth, each successive shift in LRAS is larger and larger.
What is long run aggregate supply?
The long-run aggregate supply is an economy’s production level (RGDP) when all available resources are used efficiently. It equals the highest level of production an economy can sustain. It is also referred to as an economy’s natural level of output because in the long-run an economy that is in a recession or overheated returns to its long-run ...
How do prices and outputs change in the long run?
All prices and output are flexible in the long run. When something triggers a drop in the economy’s aggregate demand, the price level, and short-term output fall – until the prices of all inputs and outputs adjust. Assume a national financial crisis lowers the demand for Janet’s delivery service and she is forced to lower her prices ten percent. Initially, she is very reluctant to decrease the amount she pays her employees, and gasoline prices remain unchanged. Profits decline, so she is willing to supply fewer newspapers at the lower price. However, in the long run, wages adjust. Some employees may accept a ten percent reduction in pay. Others may be let go since she sells fewer newspapers. The reduction in her costs boosts profits so she is again willing to provide the same number of newspapers as before. The economy has returned to the long-run aggregate supply, but at a lower price level. This is illustrated with the series of graphs below.
Why is the LRAS curve vertical?
The long-run aggregate supply (LRAS) curve is vertical because the price level has no bearing on the economy’s long-run potential. The LRAS curve intersects the horizontal axis where the factors of production are used in the most efficient manner, ...
What is the long run in economics?
When economists refer to the long run they are assuming that all prices are flexible and all inputs are variable. This includes input prices such as labor and raw materials and the prices of the final goods and services. In the long run, an economy’s potential is limited by its factors of production which include its natural resources, people, technology, entrepreneurs, and capital. Note that price is not mentioned. In the long run, production is independent of the price level. In other words, whether the price level increases or decreases, the long-run aggregate supply is unchanged.
What is the only way an economy can achieve long-term economic growth?
Increasing its long-run aggregate supply is the only way an economy can achieve long-term economic growth. Some policies that influence an economy’s long-run aggregate supply include:
Why are raw materials so expensive?
Raw materials also become more expensive because of mounting demands. Eventually, the price of all inputs increase. The higher costs return profits to normal and output is cut back to the long-run aggregate supply, but the price level has increased. This is illustrated in steps on the graphs below.
How are economies compared to long distance runners?
Economies can be compared to long distance runners. Long distance runners are most efficient when they pace themselves. They can sprint for short periods but tire and ultimately hurt their performance if they do so for too long. Like long distance runners, an economy is most efficient when it paces itself.
What does "long run" mean in macroeconomics?
But in macroeconomics specifically, the long run means long enough for all prices to fully adjust to any kind of change.
What is the long run?
a sufficient period of time for nominal wages and other input prices to change in response to a change in the price level; the long-run is not any fixed period of time. Instead, this refers to the time it takes for all prices to fully adjust
What is the LRPC curve?
Well, the LRAS has a buddy in that model too: the Long-Run Phillips Curve (LRPC), which you’ll learn about in more depth later in this course (spoiler alert!). In that model, the LRPC curve shows that, just like in the LRAS, there is no relationship between inflation and the unemployment rate in the long run.
What is LRAS in economics?
The LRAS is vertical at a value of real GDP that represents a point on the PPC. The LRAS represents a point on a country’s PPC, translated into the AD-AS model. Every point on the PPC represents the maximum sustainable capacity for production in an economy.
Why did we label this economy?
Why did we label it ? Because this combination of output represents full employment output. You can think of the LRAS curve as taking that dot (which represents a certain amount of capital goods and a certain amount of consumption goods), figuring out the real value of that output, and then graphing the real value of that output in a new model. Imagine you can take that single dot on the PPC and then stretch it out into a vertical line . . . that is the LRAS!
Why is LRAS vertical?
The LRAS is vertical because, in the long-run, the potential output an economy can produce isn’t related to the price level. There are only two things that matter for potential output: 1) the quantity and the quality of a country’s resources, and 2) how it can combine those resources to produce aggregate output.
Why are prices sticky?
In the short-run, some prices are sticky. This means that producers might respond to changes in the price level by changing their output. However, in the long-run, those prices get “unstuck,” and once they have fully adjusted the economy will produce the efficient, full employment output.
How to trace out short run aggregate supply curve?
By examining what happens as aggregate demand shifts over a period when price adjustment is incomplete, we can trace out the short-run aggregate supply curve by drawing a line through points A, B, and C . The short-run aggregate supply (SRAS) curve is a graphical representation of the relationship between production and the price level in the short run. Among the factors held constant in drawing a short-run aggregate supply curve are the capital stock, the stock of natural resources, the level of technology, and the prices of factors of production.
What is the effect of a reduction in aggregate demand?
Consider next the effect of a reduction in aggregate demand (to AD3 ), possibly due to a reduction in investment. As the price level starts to fall, output also falls. The economy finds itself at a price level–output combination at which real GDP is below potential, at point C. Again, price stickiness is to blame. The prices firms receive are falling with the reduction in demand. Without corresponding reductions in nominal wages, there will be an increase in the real wage. Firms will employ less labor and produce less output.
Why is aggregate price adjustment incomplete?
Taken together, these reasons for wage and price stickiness explain why aggregate price adjustment may be incomplete in the sense that the change in the price level is insufficient to maintain real GDP at its potential level. These reasons do not lead to the conclusion that no price adjustments occur. But the adjustments require some time. During this time, the economy may remain above or below its potential level of output.
What is the analysis of the macroeconomy in the short run?
Analysis of the macroeconomy in the short run—a period in which stickiness of wages and prices may prevent the economy from operating at potential output—helps explain how deviations of real GDP from potential output can and do occur. We will explore the effects of changes in aggregate demand and in short-run aggregate supply in this section.
How does rigidity affect output price?
Since wages are a major component of the overall cost of doing business, wage stickiness may lead to output price stickiness. With nominal wages stable, at least some firms can adopt a “wait and see” attitude before adjusting their prices. During this time, they can evaluate information about why sales are rising or falling (Is the change in demand temporary or permanent?) and try to assess likely reactions by consumers or competing firms in the industry to any price changes they might make (Will consumers be angered by a price increase, for example? Will competing firms match price changes?).
Where does long run equilibrium occur?
Long-run equilibrium occurs at the intersection of the aggregate demand curve and the long-run aggregate supply curve. For the three aggregate demand curves shown, long-run equilibrium occurs at three different price levels, but always at an output level of $12,000 billion per year, which corresponds to potential output.
Why are nominal wages sticky?
We will first look at why nominal wages are sticky, due to their association with the unemployment rate, a variable of great interest in macroeconomics, and then at other prices that may be sticky.
What can shift the long run aggregate supply curve?
Another event that can shift the long-run aggregate supply curve is an increase in the supply of labor, as shown in Figure 23.8. An increased supply of labor could result from immigration, an increase in the population, or increased participation in the labor force by the adult population. Increased participation by women in the labor force, for example, has tended to increase the supply curve for labor during the past several decades.
How is the long run aggregate supply curve determined?
The position of the long-run aggregate supply curve is determined by the aggregate production function and the demand and supply curves for labor. A change in any of these will shift the long-run aggregate supply curve.
What happens when the supply of labor increases?
An increase in the supply of labor shifts the supply curve in Panel (a) to S2, and the natural level of employment rises to L2. The real wage falls to ω2. With increased labor, the aggregate production function in Panel (b) shows that the economy is now capable of producing real GDP at Y2. The long-run aggregate supply curve in Panel (c) shifts to LRAS2.
How does aggregate production affect real wages?
Of course, the aggregate production function and the supply curve of labor can shift together, producing higher real wages at the same time population rises. That has been the experience of most industrialized nations. The increase in real wages in the United States between 1990 and 2007, for example, came during a period in which an increasing population increased the supply of labor. The demand for labor increased by more than the supply, pushing the real wage up. The accompanying Case in Point looks at gains in real wages in the face of technological change, an increase in the stock of capital, and rapid population growth in the United States during the 19th century.
How is GDP determined in the long run?
Our model of long-run aggregate supply tells us that in the long run, real GDP, the natural level of employment, and the real wage are determined by the economy’s production function and by the demand and supply curves for labor. Unless an event shifts the aggregate production function, the demand curve for labor, or the supply curve for labor, it affects neither the natural level of employment nor potential output. Economic growth occurs only if an event shifts the economy’s production function or if there is an increase in the demand for or the supply of labor.
What is aggregate production?
The aggregate production function relates the level of employment to the level of real GDP produced per period.
How does technological change affect the economy?
But for the economy as a whole, they increase worker productivity, increase the demand for labor, and increase real wages.
What would happen if the aggregate supply curve was to the right?
The last condition might temporarily lead to a short-run shift of the aggregate supply curve to the right as supplies try to shed inventory or exhaust capital that would go to waste while not replacing it. Profits in that case would likely be funneled to stable money-like investments such as reliable bonds, gold or other commodities that are likely to retain their value regardless of economic conditions.
What would a dramatic leftward shift in the aggregate supply curve represent?
A dramatic leftward shift in the aggregate supply curve would represent a decline in the willingness of producers to offer goods for sale at all price points in multiple to most sectors of an economy. Typically the kinds of phenomena that can cause this are:
What does a rightward shift in aggregate supply mean?
Long run aggregate supply shows potential output of an economy. A rightward shift in long run aggregate supply indicates increased economic potential. All factors that cause a rightward shift in production possibility curve also cause a rightward shift in aggregate supply curve such as increased human resources because of increased population, increased adult immigration, improved work ethics, increased spending on training and educating workers, increase motivation of workers, increased retirement age, deceased school leaving age, increased female participation in labour force, increased occu
What causes a rightward shift in the LRAS curve?
Increases in potential output or a rightward shift in the LRAS curve are usually due to the following: 1. Increases in quantities of factors of production. For example, an increase in the quantity of physical capital, or land (eg. discovery of oil reserves) - the economy is capable of producing more real GDP.
Why does LRAS shift?
LRAS can shift for many reasons, including: The level of spending on new technology, which enables an economy to produce in greater volume or improved quality – even using the same quantity of scarce resources. Long term inward investment from abroad, which enables increased production. 125 views.
When does a shift in the SRAS curve occur?
A shift in the SRAS curve only occurs when there’s change in the cost of production for firms.
What changes the ad curve?
These are the fiscal policy factors, a change in these factors affect the IS curve, i.e. goods market equilibrium, in effect, shifting the AD curve. A change in monetary policy of a country, increase/decrease in money supply effects the LM curve, Continue Reading.
