摘要
本文采用无限期内生时间偏好率模型 ,研究了政府花费对经济的影响 .指出长期的政府花费增加可以使资本存量水平上升 ,消费水平下降和债券持有量上升 ;同时 ,短期分析表明政府花费增加可以减少初始投资率 ,增加政府债务率水平 ;但短期的政府花费增加同样导致资本存量水平上升 。
In an infinite horizon model with endogenous time preferences, government expenditure, government bonds, and domestic capital accumulation, a permanent increase in government expenditure leads to a increase in long run capital accumulation, a decrease in domestic consumption, and an increase ingovernment bonds. Short run analysis shows that an initial increase in government expenditure leads to reduction in investment, and a rise in government bonds. On the other hand, a temporal increase in government expenditure results in an increase incapital accumulation and government bonds, and a reduction in consumption.
