Please help me in understanding and answering these questions. Thank you.

2) You are working for the central bank of your country. Your manager has asked you to write a report for the Governor of your central bank about the trade-off between inflation and unemployment as the Governor is thinking about what monetary policy to offer the government. One thing you know is that other economists in your bank have worked out that the Phillips curve takes the form: i = i_1 - 0.5 x (u - 0.06). It's all based on what happens over a year. [Ref: M 418-425, Notes 7-1/ a) You notice that the Phillips curve your co-workers has estimated for the economy implies that people's expectations of the inflation rate change in a specific way. You need to note this in your report. What is this "way"? b) You know that inflation and unemployment are affected by the natural rate of unem- ployment. You also realise that it is embedded in the Phillips curve your colleagues have estimated. So what is it? And how do you know it is this? c) Your manager tells you that you should consider a scenario that is going through the Governor's mind. The Governor thinks inflation is too high currently and is outside his contracted band. He/she would like inflation to drop by 5 percentage points. But he's aware that this has a cost in terms of higher unemployment. He'd like to know how much unemployment would rise to reduce inflation by 5 percentage points.

So you have to draw a Phillips curve diagram containing the information in a)-c)
