Economic agents are not always rational or farsighted and can make decisions according to
simple behavioral rules that vary according to situation and can be studied using the tools of …

Agent-based models (ABMs) provide a methodology to explore systems of interacting,
adaptive, diverse, spatially situated actors. Outcomes in ABMs can be equilibrium points …

Biological diversity is known to enhance the resilience of ecosystems to environmental
change. It is, however, unclear whether a high diversity of social actors analogously …

I discuss the concept of complexity and the burgeoning field of complex systems and their
relevance to sociology. I begin by comparing and contrasting various definitions of …

Institutions do not always produce behavior consistent with what theory predicts, leading
comparative scholars to turn to explanations based on historical or cultural exceptionalism …

Agent-based models are often described as bottom-up because macro-level phenomena
emerge from the micro-level interactions of agents. These macro-level phenomena include …

Strategies for sustaining cooperation and preventing exploitation by selfish agents in
repeated games have mostly been restricted to Markovian strategies where the response of …

This paper studies two equilibrium selection methods based on replicator dynamics. A Nash
equilibrium is called centroid dominant if the trajectory of the replicator dynamics starting at …

Studies concerning nonlinear political dynamics, such as regime change, focus on macro-
level structural factors and political agency. Tip** points are pitched mainly at these levels …

We propose a new deterministic evolutionary dynamic—the tempered best response
dynamic (tBRD)—to capture two features of economic decision making: optimization and …
