Is the world retracting from globalisation, setting it up for a fifth wave?
Over the past 25 years there has been lots of research and debate about the concept, the history and state of globalisation, its various dimensions and benefits.
The World Economic Forum has set out the case that the world has experienced four waves of globalisation. In a 2019 publication it summarised them as follows.
The first wave is seen as the period since the late 19th century, boosted by the industrial revolution associated with the improvements in transportation and communication, and ended in 1914. The second wave commenced after WW2 in 1945 and ended in 1989. The third commenced with the fall of the Berlin Wall in 1989 and the disbanding of the former Soviet Union in 1991, and ended with the global financial crises in 2008.
