在20世纪70年代的美国，通货膨胀率和自然失业率都上升了。让我们用这种前后不一致性模型来考察这一现象。假设政策是斟酌处置的。
a．在到现在为止所建立的模型中，当自然失业率上升时，通货膨胀率会发生什么变动？
b．现在通过假设美联储的损失函数中通货膨胀和失业都是二次的来略微改变模型，即：L(u，π)=u2+γπ2。按照与正文中相似的步骤解出斟酌处置政策下的通货膨胀率。
c．当自然失业率上升时，通货膨胀率会发生什么变动？
d．在1979年。吉米·卡特总统任命了保守派的中央银行家保罗·沃尔克出掌美联储。根据这个模型，通货膨胀和失业会发生什么变动？
In the 1970s in the United States, the inflation rate and the natural rate of unemployment both rose. Let's use this model of time inconsistency to examine this phenomenon. Assume that policy is discretionary.
a．In the model as developed so far, what happens to the inflation rate when the natural rate of unemployment rises？
b．Let's now change the model slightly by supposing that the Fed's loss function is quadratic in both inflation and unemployment. That is, L(u，π)=u2+γπ2. Follow steps similar to those in the text to solve for the inflation rate under discretionary policy.
c．Now what happens to the inflation rate when the natural rate of unemployment rises？
d．In 1979, President Jimmy Carter appointed the conservative central banker Paul Volcker to head the Federal Reserve. According to this model, what should have happened to inflation and unemployment？
第9题
当城市通过了限制房东对公寓收取租金的法律时，这些法律通常适用于已有的房屋，而不适用于任何还没有建筑的房屋。租金控制的支持者认为，这种免除保证了租金控制不会抑制新房的建设。根据前后不一致性问题评价这种观点。
When cities pass laws limiting the rent landlords can charge on apartments, the laws usually apply to existing buildings and exempt any buildings not yet built. Advocates of rent control argue that this exemption ensures that rent control does not discourage the construction of new housing. Evaluate this argument in light of the time-inconsistency problem.
