1. 1.Material 1

With a combined assets of $230.6 billion in 1990, Citigroup jumped to $668.6 billion in 1999 after merging with travel agents, nearly trebling. Before the merger of Boeing and McDonnell Douglas, Boeing’s assets were only US$ 12.6 billion in 1990 and reached US$ 36.6 billion in 1999 after the merger. After Boeing merged with McDonnell Douglas, there was no competitor in the aircraft manufacturing industry in the United States. People think that the United States is emerging as a “new monopoly economy.”

According to statistics, there were 575 joint research institutions officially registered in the United States between 1985 and 1995, and large companies such as General Motors, IBM, and AT& T is a participant in multiple research projects. Because their business is diversified and they participate in the joint research and development of many products, this provides them with opportunities to monopolize the technology market in many fields.
