Are American-style megacities or European-style urban networks the best development path for urbanizing countries like China? Can Europe’s relatively smaller cities compete with the world’s megacities by improving the transportation and communication links between them? Edward Glaeser, Giacomo Ponzetto, and Yimei Zou develop a theory of the flow of ideas within and between cities and discuss the factors that may favor consolidation into a dominant megalopolis over the balanced growth of a network of smaller cities.
If 1000 people were killed in conflict India, a country with a population of more than 1.2 billion inhabitants, would this have the same impact on the country as a whole as 1000 victims in Nicaragua, a country of 6 million inhabitants? The intuitive answer might be no, but this is exactly what most of the conflict literature is doing. Hannes Mueller makes a case for rethinking the approach of using a threshold of an absolute number of battle victims.
