Would that make the recession more or less severe? Answer: a Tax revenue declines when the economy goes into a recession because taxes are closely related to economic activity In a recession, people's incomes and wages fall, as firms' profits, so taxes on these things decline b Government spending rises when the economy goes into a recession because more people get unemployment-insurance benefits, welfare benefits, and other forms of income support c If the government were to operate under a strict balanced-budget rule, it would have to raise tax rates or cut government spending in a recession Both would reduce aggregate demand, making the recession more severe Question 2: Suppose the Government reduces taxes by VND 2000 Billion, and there is no crowding out The marginal propensity to consume (MPC) is 0.75 a) What is the initial effect of the tax reduction on aggregate demand? b) What additional effect follow this initial effects? What is the total effect of the tax cut on aggregate demand? c) How does the total effect of this VND 2000 Billion tax cut compare to the total effect of a VND 2000 Billion increase in government purchases? Why? Answer: Dr Trieu a) VND 2000B tax reduction will increase households take-home income by 2000B And because MPC = 75, Consumption will increase 1500B, therefore AD initially increases by only 1500B b) The following effect will be the multiplier effect which increase further AD up to 6000B [1500*1/(1-MPC)] c) This total effect is smaller the the effect of an increase of 2000B G purchases When G increases 2000B, AD increases initially by 2000B and therefore its total effect will be 8000B increase in AD Question 3: Based on questions related to ‘the monetary system) as below, please present your answers 11 Gold has been called “the ultimate burglar alarm.” Explain what this expression means? Answer: Government ‘Burgle” holders of their currencies by printing more money and subjecting holders to an ‘inflation tax.” Since gold prices responds quickly to evidence of inflation of an increase in inflation will cause a jump in gold prices In this way, gold serves as a burglar alarm to warn that politicians are tampering with fiat money a Suppose Vietnam attempt to pursue independent monetary and fiscal policies How will exchange rates behave? Answer: Independent monetary and fiscal policies will lead to volatile exchange rates as market participants receive and assess new information on these policies b “For a fixed exchange rate system to work the government must be able to make tight budget and monetary policies stick from the outset.” Comment Answer: A government that runs budget deficits and a lax monetary policy is unlikely to be able to maintain its commitment to a fixed exchange rate Hence, one that starts out on the wrong foot will appear to observers to be willing to make exchange rate policy subservient to other national interests Recognizing this apparent lack of government commitment to a fixed exchange rate, speculator are more likely to attack its currency, making its ability to maintain the fixed exchange rate even more doubtful 12 [...]... marginal propensity to consume (MPC) is 0.75 a) What is the initial effect of the tax reduction on aggregate demand? b) What additional effect follow this initial effects? What is the total effect of the tax cut on aggregate demand? c) How does the total effect of this VND 2000 Billion tax cut compare to the total effect of a VND 2000 Billion increase in government purchases? Why? Answer: Dr Trieu a) VND... [1500*1/(1-MPC)] c) This total effect is smaller the the effect of an increase of 2000B G purchases When G increases 2000B, AD increases initially by 2000B and therefore its total effect will be 8000B increase in AD Question 3: Based on questions related to ‘the monetary system) as below, please present your answers 11 Gold has been called “the ultimate burglar alarm.” Explain what this expression means?... revenue declines when the economy goes into a recession because taxes are closely related to economic activity In a recession, people's incomes and wages fall, as do firms' profits, so taxes on these things decline b Government spending rises when the economy goes into a recession because more people get unemployment-insurance benefits, welfare benefits, and other forms of income support c If the government... currencies by printing more money and subjecting holders to an ‘inflation tax.” Since gold prices responds quickly to evidence of inflation of an increase in inflation will cause a jump in gold prices In this way, gold serves as a burglar alarm to warn that politicians are tampering with fiat money a Suppose Vietnam attempt to pursue independent monetary and fiscal policies How will exchange rates behave?... commitment to a fixed exchange rate Hence, one that starts out on the wrong foot will appear to observers to be willing to make exchange rate policy subservient to other national interests Recognizing this apparent lack of government commitment to a fixed exchange rate, speculator are more likely to attack its currency, making its ability to maintain the fixed exchange rate even more doubtful 12
