Question 63

In the circular flow of income model for an open economy with a government sector, macroeconomic equilibrium occurs when total planned injections equal total planned withdrawals. An analyst compiles the following national accounts data for such an economy:

  • National Income (YYY) = £850 billion\text{£}850\text{ billion}£850 billion
  • Consumption (CCC) = £540 billion\text{£}540\text{ billion}£540 billion
  • Tax Revenue (TTT) = £130 billion\text{£}130\text{ billion}£130 billion
  • Investment (III) = £120 billion\text{£}120\text{ billion}£120 billion
  • Government Spending (GGG) = £150 billion\text{£}150\text{ billion}£150 billion
  • Exports (XXX) = £100 billion\text{£}100\text{ billion}£100 billion

Assuming the economy is in circular flow equilibrium, what are the values of Savings (SSS) and Imports (MMM)?

A

S=£180 billionS = \text{£}180\text{ billion}S=£180 billion and M=£60 billionM = \text{£}60\text{ billion}M=£60 billion

B

S=£310 billionS = \text{£}310\text{ billion}S=£310 billion and M=£60 billionM = \text{£}60\text{ billion}M=£60 billion

C

S=£180 billionS = \text{£}180\text{ billion}S=£180 billion and M=£140 billionM = \text{£}140\text{ billion}M=£140 billion

D

S=£180 billionS = \text{£}180\text{ billion}S=£180 billion and M=£190 billionM = \text{£}190\text{ billion}M=£190 billion
