B. is the positive relationship between consumer spending and the overall price level. C. is not .. The slope of the short-run aggregate supply curve shows that. The upward-sloping aggregate supply curve—also known as the short run aggregate supply curve—shows the positive relationship between price level and real. Short-run aggregate supply curve – shows the relationship between the Stagflation – Combination of inflation and falling aggregate output • Long-run.
The SRAS curve slopes up for two reasons: Economists used to believe that all prices were flexible. That means that if conditions change, like a recession happens, prices will quickly adapt to that change. For example, if there is a recession, high unemployment will quickly drive down wages.
Aggregate demand and aggregate supply curves (article) | Khan Academy
Lower wages make firms more willing to hire more workers. More workers mean more output, so flexible prices like wages mean that recessions should mostly fix themselves.
Or so the thinking was at the time! The Great Depression made us question the idea that all prices are flexible. Economists had to rethink what they thought they knew about how well prices adjust.
Difference between SRAS and LRAS
Price adjustment might work well in the long run, but the short run is a different story altogether. After all, wages are usually set for long time periods because of labor contracts. Businesses might lock themselves into long-term purchase agreements for other resources too. Aggregate demand is the amount of total spending on domestic goods and services in an economy.
The downward-sloping aggregate demand curve shows the relationship between the price level for outputs and the quantity of total spending in the economy. Introduction To understand and use a macroeconomic model, we first need to understand how the average price of all goods and services produced in an economy affects the total quantity of output and the total amount of spending on goods and services in that economy.
The aggregate supply curve Firms make decisions about what quantity to supply based on the profits they expect to earn. Profits, in turn, are also determined by the price of the outputs the firm sells and by the price of the inputs—like labor or raw materials—the firm needs to buy. Aggregate supply, or AS, refers to the total quantity of output—in other words, real GDP—firms will produce and sell.
The aggregate supply curve shows the total quantity of output—real GDP—that firms will produce and sell at each price level. The graph below shows an aggregate supply curve. Let's begin by walking through the elements of the diagram one at a time: The graph shows an upward sloping aggregate supply curve.
The slope is gradual between 6, and 9, before become steeper, especially between 9, and 9, The aggregate supply curve. The vertical axis shows the price level.
Price level is the average price of all goods and services produced in the economy.Introduction to short run aggregate supply
It's an index number, like the GDP deflator. Wait, what's a GDP deflator again?

The GDP deflator is a price index measuring the average prices of all goods and services included in the economy. Notice on the graph that as the price level rises, the aggregate supply—quantity of goods and services supplied—rises as well. Why do you think this is? The price level shown on the vertical axis represents prices for final goods or outputs bought in the economy, not the price level for intermediate goods and services that are inputs to production.
The AS curve describes how suppliers will react to a higher price level for final outputs of goods and services while the prices of inputs like labor and energy remain constant. If firms across the economy face a situation where the price level of what they produce and sell is rising but their costs of production are not rising, then the lure of higher profits will induce them to expand production.
Potential GDP If you look at our example graph above, you'll see that the slope of the AS curve changes from nearly flat at its far left to nearly vertical at its far right. At the far left of the aggregate supply curve, the level of output in the economy is far below potential GDP—the quantity that an economy can produce by fully employing its existing levels of labor, physical capital, and technology, in the context of its existing market and legal institutions.
At these relatively low levels of output, levels of unemployment are high, and many factories are running only part-time or have closed their doors. In this situation, a relatively small increase in the prices of the outputs that businesses sell—with no rise in input prices—can encourage a considerable surge in the quantity of aggregate supply—real GDP—because so many workers and factories are ready to swing into production.
As the quantity produced increases, however, certain firms and industries will start running into limits—for example, nearly all of the expert workers in a certain industry could have jobs or factories in certain geographic areas or industries might be running at full speed.
In the intermediate area of the AS curve, a higher price level for outputs continues to encourage a greater quantity of output, but as the increasingly steep upward slope of the aggregate supply curve shows, the increase in quantity in response to a given rise in the price level will not be quite as large.
