民主党在位，they will try to keep unemployment rate low at the

expense of high inflation since these two goals (low inflation and low unemployment rate) are hard to achieve at the same time; 共和党当政，会反过来，they will try to keep inflation low at the cost of higher unemployment rate, 他们觉得高失业率是公平竞争的自然结果。。。This is the so called "trade off theory".

 

现在这些都是短期的，看了一下指标，经济萧条机率目前还是低的
