本文建構一個商品市場完全競爭設定的內生成長模型，分別探討所得稅、生產性政府支出與貪污(賄賂)被查獲的機率，對於均衡勞動量、經濟成長與所得分配之間的影響。本文發現 (1)當政府課徵所得稅上升時，將會降低均衡就業量與經濟成長率，而從事貪污活動時間的影響不確定。在所得分配方面，將有助於所得不均度的下降。(2)生產性政府支出的提高對於均衡就業量、經濟成長、從事貪污活動時間與所得分配的影響皆為不確定。(3)貪污(賄賂)被查獲的機率提升對於均衡就業量、經濟成長、從事貪污活動時間與所得分配的影響皆為不確定。 This paper constructs an endogenous growth model with perfect competition in the commodity market. We investigate the impact of income taxes, productive government expenditures and the detection probability of corruption on the employment, economic growth, and income distribution, respectively. There are some findings in this paper: (1) when the government increases to impose upon income tax, it reduces the equilibrium employment rate, economic growth rate, and income inequality but its effect on corruption is ambiguous. (2) The increase in the productive government expenditure has an uncertain impact on the equilibrium in employment, economic growth, the activities of corruption, and the distribution of incomes. (3) Increasing the detection probability of corruption has an uncertain impact on the equilibrium employment, economic growth, the activities of corruption, and the distribution of the incomes.
