本文依據林向愷、賴惠子(2009)財政赤字現值模型:「財政赤字」等於未來政府財政努力程度的現值,探討台灣中央政府1968-2008年期間在跨期財政平衡限制下,面對財政赤字衝擊而產生未預期的財政赤字時,究竟是採行支出調整抑或收入調整以回復財政的長期平衡。本文修正一般化衝擊反應函數(Generalized impulse response function)估算未來年度歲出與歲入成長率對財政赤字的動態回應型態。同時利用Polito and Wickens(2007)的方法編製台灣的財政狀態指標(an index of the fiscal stance)做為未來特定期間內的財政狀況衡量,以為政府短期財政政策制定的依據。
