拉佛曲線分析-台灣綜合所得稅之實證研究 / An Practical Analysis of Laffer Curve - A Case Study of the Consolidated Income Tax in Taiwan

王淑惠, Wang Shu Huey Unknown Date (has links)
租稅為政府最主要籌措財源的方式,如何運用租稅政策籌措財源以舒緩財政窘迫的壓力,是當前政府最急切的關鍵和挑戰。而在若干已開發國家,因經濟體系存有拉佛效果,減稅措施將可刺激經濟活動,使稅基大幅擴大,稅收亦因此而增加。因此,本文即在探討我國綜利用伊布爾模型來探討我國在剔除物價上漲對稅收的影響後,大幅降低所得稅的邊際稅率對較高所得級距者而言,是否會有拉佛效果之產生。而研究結果顯示,減稅並未帶來豐厚的稅收,即未符合拉佛曲線負斜率段落在稅收函數改為傳統線性函數時,應用費格及麥吉之模型來探討生產因素供給彈性、地下經濟規模及過高的稅率對稅收的影響並藉以推導最適稅率。經實證估計我國1989年綜合所得稅的最適平均稅率大約為50

拉佛曲線之研究--拉佛曲線與租稅逃避--

湯國斌, TANG, GUO-BIN Unknown Date (has links)
觀察近年來一些工業化國家「稅收與稅率反向變動」的情形,彷佛落入「拉佛曲線」(Laffer Curve)負斜率的地方;為探求拉佛曲線在租稅理論基礎上的可信度,乃引發研究本文之動機。 二、研究方法: 本文以Yunker(1986)的單一部門新古典模型為基礎,首次將「租稅逃避」的概念加入模型中,重新檢視在租稅逃避行為存在的前提下,稅收的稅率彈性之變化。此外,本文根據Lucas-Rapping(1970) 之有關長期與短期總合勞動供給彈性之實證研究結果,將拉佛曲線區分為「長期拉佛曲線」和「短線拉佛曲線」,與Buchanan and Lee(1982)依「需求理論」所導出之長期和短期拉佛曲線,得以相互對映。 實證分析部分,本文以我國近二十年來的綜所稅為對象,利用時間序列分析,迴歸估計綜所稅的稅收方程式,以期瞭解綜所稅稅收的稅率彈性之正、負符號及大小;並由稅收方程式中分離出「未逃避租稅的比例」(?) 與「有效稅率」(t?),進而瞭解租稅逃漏與租稅規避對綜所稅稅基的影響。 三、研究發現: 本文將Yunker(1986)的模型修正之後發現,在租稅逃避的情況下,儘管生產要素的供給並不富於彈性,亦有可能使經濟體系落入拉佛曲線負斜率的地方。此外,本文導出稅率彈性較大的長期拉佛曲線,和稅率彈性較小的短期拉佛曲線,顯示長期下較有利於政府稅收的最大比。 我國綜所稅的實證結果發現,綜所稅的稅率彈性為正,且長期下(恆定狀態)的稅率彈性較短期內為大。至於租稅逃避的情形顯示,我國近二十年來綜所稅的有效稅率平均不到5%,稅基侵蝕不可不謂嚴重。 / Beck, John H., “AN ANALYSIS OF THE SUPPLY-SIDE EFF-ECTS OF TAX CUTS IN IS-LM MODEL”, National Tax Journal vol.32(December 1979).493-499 Bender, Bruce, “AN ANALYSIS OF THE LAFFER CURVE”, Economic Inquiry vol . 22(July 1984) ,414-420.
