一道经济学题目

Suppose that the unemployment rate is 5% which is equal to the natural rate. Inflation is at 2% which is also the level of inflationary expectations. The new Fed chair decides it is important to bring the unemployment rate permanently down to 4%. Will he be able to achieve his goal? What are the consequences of his trying to lower the unemployment rate below the natural rate? Explain using the ideas of the long-run Phillips curve model.谢谢大神们
