Boeing:how low can they fly? Essay

Prepare problems 3, 5 and 7 on pp.521 and the additional problem, Principles of Economics, Case, Fair and Oster.
Problem 3 p.521
For each of the following statements, decide wether you agree or disagree and explain your answer :
1. During period of budget surplus (when ? < ? ), the government debt grows. 2. A tax cut will increase the equilibrium level of GDP if the budget is in deficit but will decrease the equilibriumm level of GDP if the budget is in surplus. 3. If the ? ? ? = 0.90, the tax multiplier is actually larger than the expenditure multiplier. Problem 5 p.521

Expert economists in the economy of Yuk estimate the following : Real output/income 1000 billion Yuks
Government purchases 200 billion Yuks
Total net taxes 200 billion Yuks
Investment spending (planned) 100 billion Yuks
Assume that Yukers consume 75 percent of their disposable incomes and save 25 percent. 1. You are asked by the business editor of the ? ????????? to predict the events of the next few months. By using the data given, make a forecast. (Assume that investment is constant.)

2. If no changes were made, at what level of GDP (? ) would the economy of Yuk settle ? 3. Some local conservatives blame Yuk’s problems on the size of the government sector. They suggest cutting government purchases by 25 billion Yuks. What effect would such cuts have on the economy ? (Be specific)

Problem 7 p.521
Assume that in 2008, the following prevails in the Republic of Nurd : Y=200$
C=160$
S=40$
I(planned)=30$
G=0$
T=0$
Assume that households consume 80% of their income, they save 2% of their income, ? ? ? = 0.8 and ? ? ? = 0.2. That is, ? = 0.8?? and ? = 0.2?? . 1. Is the economy of Nurd in equilibrium ? What is Nurd’s equilibrium level of income ? What is likely to happen in the coming months if the government takes no action ? 2. If 200$ is the « full-employment » level of ? , what fiscal policy might the government follow if its goal is full employment ?

3. If the full-employment level of ? is 250$, what fiscal policy might the government follow ? 4. Suppose ? = 200$, ? = 160$, ? = 40$ and ? = 40$. Is Nurd’s economy in equilibrium ? 5. Starting with the situation in part (4), suppose the government starts spending 30$ each year with no taxation and continues to spend 30$ every period. If ? remains constant, what will happen to the equilibrium level of Nurd’s domestic product (? ) ? What will the new level of ? and ? be ?

6. Starting with the situation in part (4), suppose the government starts taxing the population 30$ each year without spending anything and continues to tax at that rate every period. If ? remains constant, what will happen to the equilibrium level of Nurd’s domestic product (? ) ? What will the new level of ? and ? be ?. How does your answer to this question differ from your answer to question (5) ? Why ?

– Tax multiplier ? What is the formula ?
5. From the above data :

– Derive the saving equation
– Derive the investment equation
– Derive the government expenditure equation
6. What will be the new equilibrium income when the government increases its expenditure from 1600 to 3100 ?
7. What will be the new equilibrium income when the government increases the taxes from 200 to 1200 ?
8. Assume that the equilibrium level on income/output is the one found in question (2) above. If the potential income/output is 9000 and the government intends to bring the economy to the potential level :

– By how much government expenditures should increase/decrease ? Explain. – By how much taxes should increase/decrease ? Explain.
