The aggregate demand aggregate supply model is a quite useful tool for us to understand the economy. So far, we saw only one change at a time, however, in reality, there can be multiple shocks at the same time. The economy was in long run equilibrium. Assuming all else equal, world scientists collaborated to invent a vaccine for everyone to be safe from deadly virus, raising productivity. This makes consumers and businesses optimist about the economy. At the same time, the commodity market, namely the oil market is calm, maintaining a stable supply. Given above scenario, what do you think will happen to the LRAS, SRAS and AD curves in short run? And what would happen to price level and output in the economy? What about in long run?

Using the “dynamic aggregate demand” and “dynamic aggregate supply” (DAD/DAS) model: (b) draw a graph and discuss the effect of an adverse supply shock, such as a rise in oil prices.
hello, I know for sure that answer "positive supply shock; LRAS to the right," is wrong
Please note that this is a multi part quesition; thank you so much for your time and effort it means so much to me! Figure 1: Hayek’s (Classical) AD-AS Model (Image normally goes here) Part 1: Why does Hayek’s aggregate supply curve always lead to an equilibrium level of national output equal to the full-employment level of real GDP? Part2: Hayek says that markets will heal themselves and that government should not intervene. How does the AD-AS model reflect Hayek’s idea that governments cannot increase real GDP beyond the level that the free market economy is able to produce? Part 3: Do you believe that the Hayek’s classical AD-AS model explain the factors that cause changes (shifts) in AS realistically? Why or why not?
Use shifts of the AD and AS curves to explain (a) the U.S. experience of strong economic growth, full employment, and price stability in the late 1990s and early 2000s and (b) how a strong negative wealth effect from, say, a precipitous drop in the stock market could cause a recession even though productivity is surging.
ASAP Consider the two-period real intertemporal model with investment from Chapter 11.(a) What does the aggregate supply curve, Y s, represent ? Derive the aggregate supply curve, Y s, using diagrams.
Which of the following would be positive aggregate demand shock? A) a slower money growth B) increased import growth C) faster growth of government spending D) decreased investment spending E) None of the above.
To study macroeconomics, one needs various models with different assumptions about the flexibility and/or stickiness of price levels. This is because: A.) the price flexibility is a short-run phenomenon while, the price stickiness is a long-run phenomenon. B.) the economy behaves so differently depending on how much time has passed after a demand shock. C.) various government policies are useless to eliminate the effects of an unexpected demand shock. D.) the economy behaves similarly to demand shocks regardless of the length of time.
a. write down the expressions for the AS and AD curves and interpret the expressions. what is the intuition behind the two curves? what must be true of the model parameters and variables in the long run equilibrium? b. analyze the effects of an oil supply shock that causes a temporary increase in the inflation, using the three-equation model. assume that the shock lasts for one period and then assumes the value 2%. describe the mechanisms that bring the economy back to long-run equilibrium. what happens to aggregate supply? c. consider an economy that starts out in steady state when the central bank decides to make the inflation target more ambitious. analyze the effects of a decrease in the inflation target from m to mt. explain the mechanism behind the adjustment to the new steady state.
The Covid-19 crisis and lockdown has been a supply-side shock to the South African economy. In response, the government offered a R500bn stimulus package to help cushion the blow. Use the AD-AS model, in conjunction with the IS-LM-BP, to explain the supply and demand dynamics of the shock and policy response. Where will equilibrium income and prices settle?
Now suppose history had taken an alternative turn following the Great Depression. Suppose President Roosevelt's government had not launched the "New Deal" to help the economy or WW2 had not happened. How would the American economy return back to its initial equilibrium? Explain in words and using an aggregate demand and supply plot.
Hi, could you help me solve this problem? It is often argued that the effect of a demand shock depends on the state of the economy. In particular, a given increase in aggregate demand may induce a larger increase in inflation (or price level) if the output gap is initially positive (output exceeds natural output) than if the output gap is initially negative. The argument is that when economy’s overall production capacity is almost fully used, firms cannot expand output much in response to an increase in demand.t Draw AD and AS curves that are consistent with these ideas and explain them briefly.
(Please attach a graph showing your work for each question) Suppose that the oil price sharply increased for a while, which increased production costs, causing an adverse supply shock. Use the AD-AS model to show the effects on output and the price level in both the short- run and long-run. Show the adjustment process of the economy from the short-run to the long-run. What is the effect on unemployment in short-run and long-run? Can policymakers do something to accommodate this shock? Would the outcome be different in this case?
