The Weekend Quiz – September 28-29, 2019

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.

1. From the US National Accounts, you find that in 2006, the share of Personal consumption expenditure in real GDP was 69.9 per cent and by 2008 it had fallen to 69.8 per cent. Similarly, the share of Gross private domestic investment on real GDP was 17.2 per cent in 2006 and by 2008 had fallen to 14.9 per cent (and further to 11.8 per cent in 2009). The net export deficit over the same period (2006 to 2008) fell from -5.7 per cent of real GDP to -4.9 per cent in 2008. Finally, the share of Government consumption expenditures and gross investment in real GDP rose from 18.8 per cent in 2006 to 18.9 per cent in 2008 (and 19.7 per cent in 2009). These relative changes tell you that real GDP was lower in 2008 compared to 2006 because the increase in Government spending and the falling negative contribution of net exports were not sufficient to offset the declining contribution from consumption and investment.



2. Assume that a standard monthly Labour Force data release showed that employment grew by only 400 in net terms during the last month. Other highlights were that unemployment rose by 10,700 and that the labour force participation rate fell by 0.1 per cent indicating a rise in the proportion leaving the labour force. Taken together this data tells you that:




3. If the household saving ratio rises and there is an external deficit then Modern Monetary Theory tells us that the government must increase net spending or else national output and income will fall.
