I'm on a course at the moment katrin paradise birds A prudent government must over time seek to balance spending and revenue collection in a way that assures the sustainability of debts. To do otherwise leads to instability and needlessly slow growth and courts default and economic catastrophe. Equally, however, responsible fiscal policy requires recognizing that when economies are weak and movements in interest rates are constrained â as has been the case in much of the industrial world in recent years â changes in fiscal policy will have significant effects on economic activity that in turn will affect revenue collections and social support expenditures. In such circumstances, aggressive efforts to rapidly reduce budget deficits may actually backfire, as a contracting economy offsets any direct benefits.
