B、该经济体的人均资本将会永远保持增长
C、该经济体的资本与劳动比将会下降
D、该经济体将保持高增长率,直到达到一个更高的资本劳动比
a.把人均产出(y=Y/L)表示为人均资本(k=K/L)和自然失业率的函数。描述该经济的稳定状态。
b.假定政府政策的某些变化降低了自然失业率。描述这一变化随时间的推进如何影响产出。对产出的稳定状态的影响大于还是小于立即的影响?请解释。
Consider how unemployment would affect the Solow growth model. Suppose that output is produced according to the production function Y=Kα[(1-u*)L]1-α,where K is capital, L is the labor force, and u*is the natural rate of unemployment. The national saving rate is s, the labor force grows at rate n, and capital depreciates at rate δ.
a.Express output per worker (y=Y/L) as a function of capital per worker (k=K/L) and the natural rate of unemployment. Describe the steady state of this economy.
b.Suppose that some change in government policy reduces the natural rate of unemployment. Describe how this change affects output both immediately and over time. Is the steady-state effect on output larger or smaller than the immediate effect? Explain.
a.索洛维亚的男人留在家里从事家务劳动,而妇女在工厂干活。如果一些男人开始走出家门去工作,以至劳动力增加了5%,这个经济可衡量的产出会发生什么变动?劳动生产率——定义为每个工人的产出——是提高了,下降了,还是保持不变?全要素增长率提高了,下降了。还是保持不变?
b.在第1年,资本存量为6,劳动投入为3,产出为12。在第2年,资本存量为7,劳动投入为4,产出为14。在这两年之间,全要素生产率发生了什么变动?
In the economy of Solovia, the owners of capital get two-thirds of national income, and the workers receive one-third.
a.The men of Solovia stay at home performing household chores, while the women work in factories. If some of the men started working outside the home so that the labor force increased by 5 percent, what would happen to the measured output of the economy? Does labor productivity-defined as output per worker-increase, decrease, or stay the same? Does total factor productivity increase, decrease, or stay the same?
b.In year 1, the capital stock was 6, the labor input was 3, and output was 12. In year 2, the capital stock was 7, the labor input was 4, and output was 14. What happened to total factor productivity between the two years?

C、高于资本的增长率
D、只发生在新工人加入劳动队伍时
E、只发生在新的资本设备利用新的更好的技术时
