Most of our attention focuses on the numerical simulations of a calibrated economy. Our analysis acquires the following conclusions: (i) a higher degree of monopoly power of each intermediate goods firm will impair growth and welfare, while the government’s expenditure ratio for public capital increase will have a positive impact; (ii) there is an invert-U shaped relationship between the income tax rate and the economic system; (iii) Barro proposition is not tenable; (iv) endogenous labor supply is a critical parameter to affect the choice of the income tax rate.140 bytestext/htmlen-US內生成長模型財政政策勞動內生化不完全競爭市場Endogenous Growth ModelFiscal PolicyEndogenous Labor SupplyImperfectly Competitive Product Marketsthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/252995/1/index.html
