# The Weekend Quiz – September 29-30, 2018

Welcome to The Weekend Quiz. The quiz tests whether you have been paying attention or not to the blog posts that I post. See how you go with the following questions. Your results are only known to you and no records are retained.

#### Quiz #497

• 1. In the wake of a rising household saving ratio, a nation with an external deficit will enter recession unless government net spending increases.
• False
• True
• 2. If an economy is projected to grow in real terms by around 2.1 per cent over the next 12 months. Real GDP per employed person is estimated to grow by 1.1 per cent over the same period and there is also the expectation that average weekly hours worked will remain more or less constant over the period. Which of the following labour force growth rates would provide the basis for an expectation that the unemployment rate will be lower at the end of period than at the beginning?
• 2.1
• 3.2
• 0.9
• Cannot tell because we don't know what the participation rate is likely to be.
• 3. Economists use two multipliers to estimate the impact on GDP of an expansion in government spending associated with rising tax rates. The spending multiplier indicates the extent to which GDP rises as a result of the extra aggregate spending arising from the increased government spending. The tax multiplier indicates the impact of rising tax rates on GDP as labour supply is reduced because of the disincentives associated with taxation. The net effect on GDP is the sum of these two impacts. Assume that the government increases spending by \$100 billion at the start of each year and maintains this policy for the next three years from now. Economists estimate the spending multiplier to be 1.5 and the impact is exhausted within each year (all induced consumption is completed within 12 months). The tax multiplier is estimated to be equal to 1 and the current tax rate is equal to 30 per cent (so tax revenue rises by 30 cents for every extra dollar of GDP produced ). What is the cumulative impact of this fiscal expansion on GDP after three years?
• \$135 billion
• \$150 billion
• \$315 billion
• \$450 billion

One out of three! I’ve got to stop improving. Only got no1 right. The other two fried my aged brain!

Question 1 is leaving out domestic investment. If the total domestic private sector went into saving then i would lean towards true.

Question 2 GDP = GDP/e * (L-u) For u to go down then growth of L must not be or greater than 1.

Question 3 is really a 50/50 between c and d. Since gdp has to go up more than 300 million since the Government is spending 100 million each year. Each time it spends there is a 30% tax which yields after the multiplier an additional 50 million. So it has to be d

3. Totally lost. I thought it would be 450 is total expansion take away taxes of 30% of 150 each period. So 3 times 45. So 450 -135. 315.
Hmm

1. I get fine
2. I think I get…so labour force growth cant be more than difference between real GDP growth and labour productivity growth otherwise unemployment might go up?

Why am I so clueless???? Brain too old.
