In (Eiter, Subrahmanian, and Pick 1999), the authors have introduced techniques to build agents on top of arbitrary data structures, and to “agentize” new/existing programs. They provided a series of successively more sophisticated semantics for such agent systems, and showed that as these semantics become epistemically more desirable, a computational price may need to be paid. In this paper, w...

Large collections of coupled, heterogeneous agents can manifest complex dynamical behavior presenting difficulties for simulation and analysis. However, if the collective dynamics lie on a low-dimensional manifold, then original agent-based model may be approximated with simplified surrogate near space where live. Analytically identifying such models challenging or impossible, but here we prese...

This paper develops a new unified theoretical general equilibrium model in which the interactions between heterogeneous workers and firms influence city evolutions. Given worker–firm–city framework, I study depth possible heterogenous evolutions resulting implications on labor market, as well overall productivity. In particular, it is shown that same exogenous shocks may lead to completely diff...
