两部门内生增长模型中财政政策的短期分析

SHORT-RUN ANALYSIS OF FISCAL POLICY IN A TWO-SECTOR ENDOGENOUS GROWTH MODEL WITH HUMAN CAPITAL ACCUMULATION

在一个两部门内生增长模型中,讨论政府财政政策变化对居民消费,资本积累以及经济增长的长期影响和短期影响.发现在短期内,政府增加资本收入税不仅可以增加居民消费,而且可以刺激人力资本积累,从而刺激短期经济增长.但是政府财政政策改变对长期经济增长不产生影响,而且资本收入税会降低长期的消费水平和资本存量.另外,从经济增长形态和消费者福利两个角度讨论了资本收入税的无效性.

In a two-sector endogenous growth model, this paper studies the long-run and short-run effects of fiscal policy on private consumption, capital accumulation, and economic growth. It is found that： The increase in the capital income tax not only increases private consumption, but also increases the human capital accumulation, and in turn increases economic growth. However~ government policy has no long-run effect on the economic growth, and the increasing of capital income tax rate will decrease the long-run consumption and physical capital accumulation. The welfare effects of fiscal policy is investigated too.
