The People's Republic of China (PRC) is experiencing a trend toward population concentration in its large coastal cities. However, at the same time, there is also a distortion of city size toward small cities in the country. That is to say, the urban population in the PRC should further...

We analyze the interplay of group identity and inter-group conflict in a contest where each of two conflicting groups can develop either a group or an individualistic identity. Contest structures impact on the adoption of identities which themselves influence behavior in the contest. We show the...

Solar geoengineering has received increasing attention as an option to temporarily stabilize global temperatures. A key concern surrounding these technologies is that heterogeneous preferences over the optimal amount of cooling combined with low deployment costs may allow the country with the...
