Then, work through the notes at your own pace. Try to do each example as they are encountered in the notes. If you need any help, all solved examples are included in the VB Code folder.

From 1914 through 1980, GDP data for most countries were mainly sourced from Mitchell (2003). 7 Government publications were also used for collecting GDP data for some countries, including Canada, Italy, Japan, the Netherlands, New Zealand, the United Kingdom, and the United States.
