Readers who wish to see how the business cycle calculations for this book were done, as well as how to create their own spreadsheet and graphs, can use the attached program. You need only paste the series into the appropriate date on the spreadsheet.
- The users need only paste their data at the first quarter 1970.
- The “cycle base” is the average of a variable over the whole cycle.
- The “original data” are your series, divided into nine stages of the cycle. Stage 1 is the initial trough, stages 2, 3, and 4 are the expansion; stage 5 is the cycle peak; stages 6, 7, and 8 are the expansion; and stage 9 is the final trough.
- The “cycle relative” is defined as the original data at each stage divided by the cycle base.
- The “expansion amplitude” is the peak value minus the initial trough.
- The “contraction amplitude” is the final trough value minus the peak.
