Q7) At T1, an economy is in long-run equilibrium at a real interest rate of 4%, a price level of 100, and
with an expected inflation rate of 0%. If in T2 the actual price level is 95, then in that time period:
A) r = 4%, i = 4%
B) r= 9%, i -1%
C) r= -1%, i 4%
Dr= -1%, i 9%

Assume the U.S. is a closed economy and that it is starting out in both SR and LR equilibrium. Assume that not all prices are sticky. The Fed has been raising interest rates the last few months and will likely continue to do so. One result of this is that home loan (mortgage) rates have shot up from < 3% to over 7%, sending house prices across the U.S. lower (on average). Banks are also seeing loan default rates increase (not just for home loans, but for all loans) and are being more cautious about the loans they make and are increasing the amount of money they set aside to handle the expected loan defaults. A. Using appropriate graph(s), show and explain the short-run impact(s) of the events described above on the U.S. economy. B. Using just an AD/AS graph (and starting from your result in A), show and explain what happens in the long run. Put your new graph and explanation below
Based on research conducted by the Department of Economic Analysis, the government and policy advisors of an economy believe that the full employment GDP is $7500 billion, and Pe, the overall expected price level is 118. In addition, the researchers estimate that the short run aggregate
supply equation is Y = Ypot + 80 (P - Pe), where Ypot is the potential level of output. In addition, the researchers estimate that the short run aggregate supply equation is Y = Ypot + 80 (P- Pe), where Ypot is the potential level of output. In 2016, the population was 400 million, and the structure
of the economy was described by the following equations for household consumption behavior and taxes received: C = 100+ 0.8DI, and T = 0.25Y where all monetary values are in billions of dollars. Government spending was fixed at $1700 billion, and firm's investment behavior was fixed at
$800 billion. Trading is allowed in this economy and in 2016, trading occurred such that the trade account was balanced.…

- Macropoland, a country that is a natural gas and oil importer, has a natural rate of unemployment (at the full employment level of GDP) that is about 4.5%, and the long run average rate of inflation over time has been about 2%. However, during the period 1973-1974, the country experienced an inflation rate of about 15% while simultaneously experiencing unemployment of nearly 13%.At the present time, Macropoland is experiencing very sluggish consumption and investment (a result of a fall in the housing market), and unemployment has again edged up to around 9%.
