6. Why the aggregate supply curve slopes upward in the short runIn the short run, the quantity of output supplied by firms can deviate from the natural level of output if the actual price level deviates from theexpected price level in the economy. A number of theories explain reasons why this might happen.For example, the sticky-price theory asserts that the output prices of some goods and services adjust slowly to changes in the price level. Supposefirms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. Many of the firms sell theirgoods through catalogs and face high costs of reprinting if they change prices. The actual price level turns out to be 90. Faced with high menu costs,the firms that rely on catalog sales choose not to adjust their prices. Sales from catalogs will▼, and firms that rely on catalogs willrespond bythe quantity of output they supply. If enough firms face high costs of adjusting prices, the unexpected decrease in the pricelevel causes the quantity of output supplied tothe natural level of output in the short run.Suppose the economy's short-run aggregate supply (AS) curve is given by the following equation:Quantity of Output Supplied = Natural Level of Output + ax (Price LevelActual - Price Level Expected)The Greek letter a represents a number that determines how much output responds to unexpected changes in the price level. In this case, assumethat a = $2 billion. That is, when the actual price level exceeds the expected price level by 1, the quantity of output supplied will exceed the naturallevel of output by $2 billion.Suppose the natural level of output is $60 billion of real GDP and that people expect a price level of 100.On the following graph, use the purple line (diamond symbol) to plot this economy's long-run aggregate supply (LRAS) curve. Then use the orangeline segments (square symbol) to plot the economy's short-run aggregate supply (AS) curve at each of the following price levels: 90, 95, 100, 105,and 110.PRICE LEVEL12512011511010510095908580750102030 40 50 60 70OUTPUT (Billions of dollars)80 90 100AS&LRAS?)The short-run quantity of output supplied by firms will exceed the natural level of output when the actual price levelthat people expected.the price level

Suppose we have a market with upward sloping supply and downward sloping demand curves. After which of the following shocks can we guarantee that equilibrium price will increase? A shock which simultaneously shifts the supply curve downwards and the demand curve upwards. A shock which shifts the demand curve downwards. A shock which simultaneously shifts the supply curve downwards and the demand curve downwards. A shock which shifts the supply curve upwards. More than one of the above.

Should the government use monetary and fiscal policy in an effort to stabilize the economy? The following questions address the issue of how monetary and fiscal policies affect the economy, as well as the pros and cons of using these tools to combat economic fluctuations. The following graph plots hypothetical aggregate demand (AD), short-run aggregate supply (AS), and long-run aggregate supply (LRAS) curves for the U.S. economy in May 2026. Suppose the government chooses to intervene in order to return the economy to the natural level of output by using policy. Depending on which curve is affected by the government policy, shift either the AS curve or the AD curve to reflect the change that would successfully restore the natural level of output.

Between 2007 and 2009, the United States experienced a severe financial crisis and economic downturn commonly known as the Great Recession. Starting in 2006, housing values fell 30%, causing losses in mortgage-backed securities for families and financial institutions. The recession was marked by a drop in aggregate demand that caused a decline in GDP and an increase in unemployment. Attached is an example of an aggregate demand and aggregate supply (AD/AS) model that illustrates the general trends of the U.S. economy during the Great Recession. How did the AD/AS equilibrium change over time? Support your claims by referring to your AD/AS model. Select an economic factor (GDP, unemployment, price level) and explain what impact any shifts in AD or AS (or both) had on your chosen factor. Please tailor the answer according the AD/AS model in layman's terms
FILL IN THE BLANKS Inflation measures the changes in the level of in the economy. Demand-pull inflation is caused by a shift in the aggregate demand curve, while cost-push inflation is caused by a shift of the aggregate supply curve. When the price level is increasing by an extremely high rate, the economy is said to be experiencing . Stagflation occurs when the economy is experiencing high inflation, high unemployment, and low at the same time. To combat inflation, the government can use contractionary monetary policy which will also lead to interest rates. Note, however, that there is a short-run tradeoff between inflation and as illustrated by the Philips Curve. Inflation is stable when the unemployment rate is equal to the rate of unemployment.
Price level (P) LRAS, LRAS2 SRAS, E SRAS, AD2 AD, Real GDP (Y) Based on the figure, which of the following would cause the aggregate demand curve to shift from AD1 to AD2?
The graph below is associated with a hypothetical country. Consider a decrease in aggregate demand (AD). Specifically, aggregate demand shifts to the left from AD₁ to AD2, causing the quantity of output demanded to fall at each price level. For instance, at a price level of 140, output is now $200 billion, where initially it was $300 billion.

How would you define sticky prices
Explain briefly three important reasons why firms have sticky prices in the short run. Given an example of a price that is sticky in the short run but flexible in the long run.
Are all prices in the economy equally inflexible? Which ones show large amounts of short-run flexibility?
What happened first was a major policy-induced supply shock. The lockdown forced firms in several directly affected sectors, from restaurants to hotels to airlines, to halt (or at least to drastically decrease) supply. In contrast to other supply shocks analyzed earlier in the book, many firms had no choice other than to stop or decrease production. As a result of sharply lower output, and thus lower income, and of increased uncertainty, this shock had a major effect on demand, not just in the sectors directly affected by the lockdown, but also in the non-affected sectors. Thus, the outcome was a combination of a supply shock and a sharp demand response. In that context, the role of macroeconomic policy was twofold. First: While it could not do much to increase output in the affected sectors, it needed to protect the firms in those sectors from going bankrupt and the workers who lost work from going hungry. Second: It needed to limit the effect of lower demand in the non-affected…
