One could argue that showing the government’s future funding shortfall in terms of total
receipt and outlay time series would capture such a policy change as an upward shift in
both series. However, other policies could be implemented that would maintain both the
projected levels of revenues and expenditures and the gap between them (annual deficits),
yet exert real economic effects by redistributing resource across generations. Consider
Figure 3.3, which shows stylized profiles by age of payroll tax and consumption tax
payments. Because the consumption tax profile is flatter and extends across older
individuals, a permanent pay-as-you-go structural tax change - that is, an annually
revenue-neutral switch from consumption to labour income taxes - time would
accomplish a sizable redistribution of tax burdens and wealth across generations.

Euros/Year
As in the case of the pay-as-you-go expansion of public pensions, this policy also
provides a windfall benefit to current older generations but reduces the lifetime resources
of younger and future generations.25 However, such a policy change would be invisible to
Figure 3.1’s fiscal measure - the time series of projected revenues, expenditures, and
deficits. If propensities to consume out of resources of older generations are different
(say, higher) than those of younger generations, permanent redistributive policy changes
of this type would very likely exert real economic effects - affecting saving, capital
formation, interest rates, and eventually inflation and exchange rates.
The above discussion suggests that when policymakers enact diverse fiscal changes
designed to alter the time profiles of expenditures and revenues to reduce short-term
deficits, only some of those policies may be reflected in traditional cash-flow measures
Generally, a reduction of consumption taxes would make all existing assets more valuable because
the consumption financed through their sale would now face a lower tax rate. Much of the immediate
increase in asset values arising from this policy would benefit existing older generations who hold
most of the country’s wealth.
