Generational accounting and intergenerational welfare

We investigate the intergenerational welfare implications of Generational Accounting when it is used as the basis for intertemporal fiscal policy decisions. In particular, we consider an economy with a PAYGO social security system out of steady state due to a permanent fall in fertility. In a highly stylized CGE overlapping generations model we illustrate that policy recommendations based on a standard application of Generational Accounting may not be compatible with intertemporal welfare maximization. Our model provides an example where such policies are either time inconsistent or welfare-decreasing.
