登录劳工统计局的网站(www.his.gov)。对于过去5年中的每1年，找出用(包括所有项目的)消费者物价指数和用剔除食品和能源的CPI衡量的通货膨胀率。比较通货膨胀的这两种指标。为什么它们可能不同？这些不同可能告诉你关于总供给曲线和短期菲利普斯曲线的哪些移动？

Go to the Web site of the Bureau of Labor Statistics (www.bls.gov). For each of the past five years, find the inflation rate as measured by the consumer price index (all items) and as measured by the CPI excluding food and energy. Compare these two measures of inflation. Why might they be different？ What might the difference tell you about shifts in the aggregate supply curve and in the short-run Phillips curve？
