This paper studies the impact of interaction topologies on individual and aggregate behavior in environments with social interactions. We study social interaction games of an infnitely large population with local and global externalities. Local externalities are limited within agents'...

We study the interactions and dynamics of human capital, growth and inequality by explicitly embedding networks into a standard endogenous growth model with overlapping generations. The human capital of a household depends on investment in education and on average human capital of the...

The diffusion of two competitive, interchangeable, and durable goods is studied under the framework of a spatial game where consumers are distributed on a two-dimensional square lattice and play 3$\times$3 symmetric coordination-like games with their nearest neighbors. There are three...

International transit traffic between countries can be expected to increase in the future. This paper investigates whether international policy coordination is appropriate in the case of international transit traffic causing a local environmental externality. This issue is analysed in a...
