With a bit of technical assistance, I was able to do a better job of quantifying the IMF’s recommended fiscal path for Japan.
The IMF wants a 50 to 100 basis point rise in Japan’s consumption tax every year for the foreseeable future, starting in 2017. A 50 basis point rise would result in between 20 and 25 basis points of GDP in structural fiscal consolidation a year (the call for the tax increase is in paragraph 23 of the staff report, and is echoed in the IMF’s working paper).
The IMF doesn’t want Japan to continue relying on fiscal stimulus packages, which typically have funds for public investment and the like (paragraph 23). As a result, there is a 60 basis points of GDP consolidation from the roll-off of past stimulus packages (the change in the structural primary balance is in both table 1 on p.38 table 4 on p.41 of the staff report).
That implies 80 to 85 basis points of GDP in structural fiscal consolidation.
But, in the staff working paper (not formal advice, but it clearly reflects the IMF’s overall recommendations), the preferred policy scenario shows an 80 basis point of GDP increase in temporary transfers and public wages to support the proposed incomes policy (this is in the working paper appendix, in table I.1 on p. 33).
Net it all out; the result is basically a neutral stance, not the consolidation I initially suspected. The 0.5 percent of GDP fall in general government net lending/borrowing in table 2 on p. 25 of the working paper stems from a fall in interest payments and an increase in nominal GDP that is projected from the new incomes policy.*
Actually if you look at table 4 in the staff report, Japan’s is expected to receive more in interest income than in pays out in interest in 2017. Japan’s government is projected receive 1.6 percent of GDP in interest on its assets (including its foreign reserves, which are largely held by the ministry of finance) and pay 1.3 percent of GDP in interest on its debt. The total fiscal deficit is thus smaller than the primary fiscal deficit in 2017. Welcome to the world of negative interest rates.
