The positive slope of the short-run aggregate supply curve, reflecting the direct relation between the price level and real production, results for three primary reasons--inflexible resources, frictional and structural unemployment, and purchasing power imbalances.
What is aggregate supply curve?
Recap:
- The AS curve shows the quantity of output (income) produced at alternative price levels.
- The AS curve is upward sloping because, ceteris paribus, higher prices increase producer’s profits, creating an incentive to produce more.
- The AS curve shifts due to changes in three non- price determinants of AS, viz., resources, technology, and expectations.
What are some examples of aggregate supply?
Key Takeaways
- Total goods produced at a specific price point for a particular period are aggregate supply.
- Short-term changes in aggregate supply are impacted most significantly by increases or decreases in demand.
- Long-term changes in aggregate supply are impacted most significantly by new technology or other changes in an industry.
What shifts aggregate demand and supply?
Short-run Shifts
- Nominal Wages. An increase in nominal wages increases production costs, hence a leftward shift in the aggregate supply curve.
- Input Prices. Higher input prices increase production cost and cause output reduction. ...
- Taxes and Subsidies. Increased taxes result in high production costs that shift the curve to the left. ...
What is aggregate supply?
Aggregate supply, also known as total output, is the total supply of goods and services produced within an economy at a given overall price in a given period. It is represented by the aggregate supply curve, which describes the relationship between price levels and the quantity of output that firms are willing to provide.
Is the short-run aggregate supply curve positive?
SRAS shows that the short-run relationship between price level and aggregate output is positive, so this should always be an upward sloping curve.
What are 3 reasons the short-run aggregate supply curve slopes upward?
Why is the aggregate supply curve upward sloping in the short-run quizlet?
Why is the aggregate supply curve upwards?
Why is aggregate supply curve vertical in long run?
How does one explain the changing slope of the aggregate supply as curve quizlet?
Which of the following causes the short-run aggregate supply curve to shift to the left?
What is the difference between the short and long run?
In macroeconomics, the distinction between the short run and the long run is commonly thought to be that, in the long run, all prices and wages are flexible whereas in the short run, some prices and wages can't fully adjust to market conditions for various logistical reasons.
What would happen if a business owner thought that the price of what he was selling was due to an increase
If a business owner thought that the increase in the price of what he was selling was due to an increase in the general price level in the economy, he or she would reasonably expect the wages paid to employees and the cost of inputs to soon rise as well, leaving the entrepreneur no better off than before. In this case, there would be no reason to expand production.
The Sticky-Wage Theory
The first explanation of the upward slope of the short-run aggregate-supply curve is the sticky-wage theory.
The Sticky-Price Theory
Some economists have advocated another approach to explaining the upward slope of the short-run aggregate-supply curve, called the sticky-price theory. As we just discussed, the sticky-wage theory emphasizes that nominal wages adjust slowly over time.
The Misperceptions Theory
A third approach to explaining the upward slope of the short-run aggregate-supply curve is the misperceptions theory.
Summing Up
There are three alternative explanations for the upward slope of the short-run aggregate-supply curve:
The Sticky Wage Theory
The Sticky Price Theory
- The sticky price theory states that the short-run aggregate supply curve slopes upward because the prices of some goods and services are slow to adjust to changes in the overall price level. That means when the overall price level falls, some firms may find it hard to adjust the prices of their products immediately. This causes sales to drop, which in turn leads to a decrease in the q…
The Misperceptions Theory
- According to the misperceptions theory, the short-run aggregate supply curve is upward sloping because changes in the overall price level can temporarily mislead suppliers about what is happening in their individual market. That means, when the price level falls, many firms will notice a fall in the price of the goods and services they sell and reduce production because they believ…
Summary
- While the aggregate supply curve is perfectly vertical in the long run, it is upward sloping in the short run. There are three theories that try to explain why suppliers behave differently in the short run than they do in the long run: the sticky wage theory, the sticky price theory, and the misperceptions theory. According to the sticky wage theory, the upward slope of the short-run a…
