Abstract:	動態隨機一般均衡模型以個體最適化為基礎, 得以對總體經濟變數提供更具理論基礎的分析。我們根據Traum and Yang (2011) 的模型, 在資本所得稅、勞動所得稅與投資具體技術等內生變數中,納入消息衝擊; 試圖了解當經濟個體所掌握的資訊集合因消息衝擊而擴展時, 個人最適經濟決策將如何變動, 並因而影響總體經濟的動態調整過程。結果發現, 當考量消息衝擊時, 衝擊反應函數將呈現一駝峰型態, 而非傳統的單調遞增遞減模式。We construct a medium-scale dynamic stochastic general equilibrium (DSGE) model in which news shocks on two distortionary taxes rules and investment-speciﬁc technology are considered. We ﬁnd that such anticipated shocks expand agents’ information set thus agents will take action preemptively before any tax policy act. The resulting impulse response functions display hump-shaped pattern that is diﬀerent from those to contemporaneous policy shocks.
