3.2 Fiscal Reaction Function
The equation for fiscal reaction function is estimated by using ordinary least square and standard errors are
adjusted for autocorrelation and heteroscedasticity. The results show that fiscal policy in Pakistan is
sustainable as there exists a positive relationship between PS and lag PL or alternatively negative relationship
between budget deficit-to-GDP ratio and debt-to-GDP ratio as it was previously explained by (Bohn 1998).
The small magnitude of the co-efficient indicates the existence of sustainability in weak from. These results
are in correspondence with inter temporal budget constraint. This result supports Bohn predication that
surplus (deficit) should respond negatively (positively) to change in government expenditure.
