自然率假说（Natural Rate Hypothesis)

自然失业率(natural rate of unemployment)

考虑失业会如何影响索洛增长模型。假定产出是根据生产函数Y=K^a[(1-u＜sup＞*＜/sup＞)L]^1-a而生产的。式中，K为资本；L为劳动；u^*为自然失业率。国民储蓄率为s，劳动力增长率为n。资本折旧率为δ。

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=K^α[(1-u＜sup＞*＜/sup＞)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.
