CHAPTER 3. STATISTICS AND TIME SERIES SOLUTIONS by Wei Lin and Yingying Sun (University of California, Riverside) Exercise 1 a. Let RPCE and RDPI denote “real personal consumption expenditure” and “real disposable personal income” respectively. Their growth rates are calculated as follows, G RPCEt = 100 × [log(RPCEt) − log(RPCEt−1)] G RDPIt = 100 × [log(RDPIt) − log(RDPIt−1)]. Figure 1 and Figure 2 plot G RPCEt and G RDPIt respectively. From visual inspection of the ...
