A、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=Ka[(1-u<sup>*</sup>)L]1-a而生产的。式中,K为资本;L为劳动;u<sup>*</sup>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。ConsiderhowunemploymentwouldaffecttheSolowgrowthmodel.SupposethatoutputisproducedaccordingtotheproductionfunctionY=Kα[(1-u<sup>*</sup>)L]1-α,whereKiscapital,Listhelaborforce,andu<sup>*</sup>isthenaturalrateofunemployment.Thenationalsavingrateiss,thelaborforcegrowsatraten,andcapitaldepreciatesatrateδ.a.Expressoutputperworker(y=Y/L)asafunctionofcapitalperworker(k=K/L)andthenaturalrateofunemployment.Describethesteadystateofthiseconomy.b.Supposethatsomechangeingovernmentpolicyreducesthenaturalrateofunemployment.Describehowthischangeaffectsoutputbothimmediatelyandovertime.Isthesteady-stateeffectonoutputlargerorsmallerthantheimmediateeffect?Explain.
