Book Review of Anne Narazaki's
New Century, New Business
Reviewed by John Gilliam
Anne Narazaki's recent book, New Century, New Business, seeks to examine the new tech-nologies that are critical for global business and how they affect today's corporate transactions. Ms.Narazaki argues that while economic transactions of one kind or another have taken place for thou-sands of years, the impact of changing technology on business has become obvious only recently. In fact, as new technologies have grown more prevalent, Ms. Narazaki observes, international busi-nesses have increased in size and number. At the same time, the time required to conduct each business transaction has decreased.
Mr. Narazaki illustrates her observations with detailed examples of recent business transac-tions. Citing the merger of Poynter Technologies and Carce Company, which created the largest fi-nancial services company in the world, Ms. Narazaki explains the effect technology has on the val-uation of a company, on communication between the managements of different companies, and on stock and funds trading.
Those of us who take an interest in the interaction between business and technology will find Ms. Narazaki's ideas persuasive. The view that business cannot survive without keep~ing up with new technology has become today's corporate reality.
