Answer:
D) the AD curve will shift out, causing an increase in the Japanese price level, but not change in output.
Step-by-step explanation:
If the government starts to increase spending, the total income will increase, shifting the AD curve outwards. Generally this situation would increase both the general price level (inflation) and total output (AS curve). But since the economy is already at full employment, real output will increase minimally (if any increase at all). The largest effect will be felt in the rise of inflation.
