Suppose, in the base year, a typical market basket purchased by an urban family costs $250. In Year 1, the same market basket cost $950. What is the consumer price index (CPI) for Year 1? If the same market basket costs $1,000 in Year 2, what is the CPI for Year 2? What was the Year 2 rate of inflation?

Last year the jones family earned $40,000. This year their income is $42,000. If the inflation rate was 10%, did the jones family experience an increase/decrease/no change in their Normal income? Did the jones family experience an increase/decrease/no change in the real income ?

Two countries, Country N in North America and Country S in South America, have the same CPI basket. Year 2000 is the CPI base year for both countries. In that year, the cost of CPI basket in Country N is $N100, and in country S is $s1000, where $N and $s are their respective currencies. Twenty years later, in 2020, the CPI in Country N rose to 240, and in Country S to 360. a) In the ideal world in which the purchasing power parity (PPP) holds true, what should be the nominal exchange between $s and $N in Year 2000 and in Year 2020. Show calculations and explain the change in nominal exchange rate. b) Suppose in reality, the nominal exchange rage between the two currencies is 18 $s per $N in Year 2020. First, explain why the nominal exchange rate differs from your calculation above. Second, calculate the real exchange rate between the two countries, and explain the meaning of your calculated result. c) During Year 2021, the growth of the real GDP in the two countries are, 0% in country…

Here are some recent data on the US consumer price index:  Year  CPI  Year  CPI  Year  CPI  2016  240.0  2011  224.9  2006  201.6  2015  237.0  2010  218.1  2005  195.3  2014  236.7  2009  214.5  2004  188.9  2013  233.0  2008  215.3  2003  184.0  2012  229.6  2007  207.3  2002  179.9    Compute the inflation rate of each year 2003-2016 and determine which were years of inflation. In which years did deflation occur? In which years did disinflation occur? Was there hyperinflation in any year?
