Conclusions
This chapter illustrates the difficult situation facing Japanese fiscal policy in the years ahead. On the one hand, high public debt and adverse population dynamics increasingly constrain the government’s room for maneuver, suggesting that strong policy adjustments will eventually be required to put public finances back on a sustainable footing. Reforms currently implemented by the government are a step in the right direction, but further measures in both the pension and health systems will be needed to avoid a large increase in payroll taxes and government transfers that would distort incentives and harm economic growth.
On the other hand, the model’s simulation results suggest that ambitious debt stabilization, particularly through cuts in public investment and other expenditure, and further reductions in social security benefits could result in substantial short-term output costs, posing a risk to the recovery. This is particularly true in the case of public investment cuts, where the multipliers are generally believed to be larger. Therefore, as long as private demand remains fragile, fiscal adjustment policies would have to be implemented cautiously.
However, in view of the serious aging problem, once the recovery is on a sound footing, japan will need to implement a long-term fiscal strategy that will return the public finances to a sustainable position. This chapter suggests that public investment cuts, base-broadening measures for income taxes, some increase in the consumption tax, and reductions in social security benefits are likely to be the key building blocks of the longer-term solution.
