Menus an indicator of globalization

Globalization comes from many directions. And can be observed in many ways. In one, as reported in the latest edition of Harvard Business Review, some researchers tried to tell where most economic activity was going on by reading the satellite images of lights on Earth.

The most lights come from the "contiguous lighted regions", led by the Boston-New York-Washington corridor, followed by about 30 others. In Asia, the two largest ones are the Shanghai-Nanjing-Hangzhou triangle in China and the area surrounding New Delhi and Lahore in India.

We know from ancient times that cities or clusters of cities on major transportation routes are more likely to boast the most prosperous businesses - like Xi'an that connected the Silk Road, and later Guangzhou and Quanzhou (a town in Fujian province) that connected the Silk Road to the sea.
