Explanation:

• The Global Competitiveness Report was originally co-published by the IMD World Competitiveness Center and the World Economic Forum (WEF) under the title of ―World Competitiveness Report.
• Subsequently, from this collaboration, two publications evolved. In 1996, the name of the report published by the IMD World Competitiveness Center was officially changed to World Competitiveness Yearbook after the co-publication with the WEF ended.
• Both IMD and WEF began to publish their own World Economy Rankings and eventually, the WEF‘s publication will become the global competitiveness report.
