2018 Macroeconomics FRQ #2
Watch me answer it here
2. Assume the economy of Ucheleand is currently at full employment. The government of Ucheland reduces the tax rate on household interest earnings.
1st you must know what household interest earnings are - interest that people earn on the savings in their bank accounts. If the government reduces the tax on those savings, then people will save more...
(a) What will happen to private savings in Ucheland?
Private savings will increase.
(b) Draw a CLG of the loanable funds market, and show, the effect of the change in private savings identified in (a) on the equilibrium real interest rate.
(c) Given the Real Interest Rate change identified in part (b), answer the following.
(i) What is the short-run effects on aggregate demand? Explain.
If the supply of loanable funds increases, driving the RIR to fall, then citizens will be more likely to take out loans and invest. Investing will shift the AD curve rightward.
(ii) What is the long run effect on the potential real GDP. Explain.
I believe this question is asking about growth in the Long-Run.
Potential GDP is the curve on the PPC. = Any point on the PPC
boundary is where resources are Allocatively efficient and referred to as Potential GDP. Potential, as this
is the best a society could achieve with all available resources actively
engaged.

If there is more investment, then we assume that some of this new investment will be investment in capital formation, this new capital creation will push out the PPC boundary = more LR Growth.

1) Assume the US economy is in recession.
(a) Draw a CLG of the LRAS, SRAS, and AD curves, Show each of the following.
(i) Current price level, labeled PL1
(ii) Current output, labeled Y1

| US in Recession |
2) Now assume the Euro-Zone, a major trading partner of the US, enters into a recession.
(i) What will be the effect on US exports to the Euro-Zone? Explain.
The effects of a recession in the Euro-Zone will lead to less US goods being purchased by Euro-Zone citizens. Less purchase of goods from the US means that the US exports will decline. You could also talk about prices of goods will fall during a recession in the Euro Zone and therefore Euro citizens will find their own goods relatively cheaper or that aggregate incomes in the Euro-zone will fall and that will make the US produced goods relatively more expensive therefore less will be purchased from the US. If US exports decrease then AD shifts left.
(ii) On your graph and part (a), show, the effect of the change identified in part (b)(i) on real output in the US.
(iii) What will be the change in identified in part (b)(ii) on unemployment in the US.
If countries don't buy our stuff (exports fall) then AD will decrease, the US slides further into a recession and a recession is characterized by a lower PL, less output, and higher levels of unemployment.
3) Assume the Euro-Zone recession causes a decrease in demand for US dollars in the FOREX.
(i) Will the euro appreciate, depreciate, or remain unchanged against the US dollar? Explain.
If the Euro-Zone isn't demanding our goods then the demand for US dollars is decreasing. If the demand for US dollars is falling then the value of the US dollar must be depreciating. That means that the Euro must be appreciating relative to the US dollar.

(ii) Draw a CLG of the FOREX for $ dollars, and show the decrease in demand for dollars on the exchange rate for dollars.
I read this two ways, which in essence are saying the same thing
1) the demand for US dollars is decreasing therefore the value of the US dollar is decreasing and/or
2) the number of Euro's it takes to buy 1 US dollar is decreasing, meaning that the Euro's value must be appreciating.
D) Assume the US implements expansionary monetary and fiscal policies. In the absence of complete crowding out, what will be the effect of these policies on each of the following?
(i) Aggregate Demand in the US - Aggregate Demand will increase because of the expansionary monetary and fiscal policies.
(ii) Price Level - The price level will increase, as AD shifts rightward due to the expansionary policies the PL will increase.
(iii) Interest Rates in the US - Understand that as the US Government uses expansionary fiscal policy (GS increases or Taxes decreased) the (RIR) Real Interest Rate will increase and as the FED uses expansionary monetary policy (Buys Bonds, decreases the (RRR) Required Reserve Ratio, or the (DR) Discount Rate) the Nominal Interest Rate will be increased as the (MS) Money Supply increases.
