Over the years, many different agent programming languages have been proposed. In this paper, we propose a concept called Agent Programs using which, the way an agent should act in various situations can be declaratively specified by the creator of that agent. Agent Programs may be built on top of arbitrary pieces of software code and may be used to specify what an agent is obliged to do, what ...

We propose a new type of social interaction as knowledge transactions. Tow agents consider to trade a set of Heterogeneous knowledge on which they have different value judgments. We aggregate by their different value judgments with threshold. The knowledge transactions are formulated as symmetric coordination games. We investigate what types of knowledge will be successfully traded through the ...

A non-cooperative model of network formation is developed. Agents form links with others based on the cost of the link and its assessed beneÞt. Link formation is one-sided, i.e., agents can initiate links with other agents without their consent, provided the agent forming the link makes the appropriate investment. Information ßow is two-way. The model builds on the work of Bala and Goyal, but a...

The present paper analyzes a network formation problem, mainly based on the framework presented in [Bala-Goyal 2000]. We depart from their assumptions in two crucial aspects. On one hand, we assume that connecting to an agent pays off not only for the number of connections that the agent can provide but also for her intrinsic value. Since the values of the agents (which represent the amounts of...

A substantial amount of economic activity involves problem solving, yet economics has few, if any, formal models to address how agents of limited abilities find good solutions to difficult problems. In this paper, we construct a model of heterogeneous agents of bounded abilities confronting difficult problems and analyze their individual and collective performance. By heterogeneity, we mean dif...

I show how to construct a stochastic long-lived overlapping generations model, based on a non-stochastic model developed by Olivier Blanchard [2] and Philippe Weil [14], that nests the RBC model as a special case. My innovation over previous work is to add an aggregate stochastic shock. I provide three different calibrations of the model. One mimics the RBC model and the other two are heterogen...

In all the existing literature on survival in heterogeneous economies, the rate at which an agent vanishes in the long run relative to another agent can be characterized by the difference of the so-called survival indices, where each survival index only depends on the preferences of the corresponding agent and the properties of the aggregate endowment. In particular, one agent experiences extin...

This article introduces a multiagent simulation framework for investigating the emergence of niche markets for environmentally innovative products. It clarifies how consumer preferences, business strategy, and government policy interact during market development. The framework allows investigation of the effects of uncertainty and agents’ corresponding coping strategies. We describe the model, ...

With the increase in agent-based applications, there are now agent systems that support concurrent client accesses. The ability to process large volumes of simultaneous requests is critical in many such applications. In such a setting, the traditional approach of serving these requests one at a time via queues (e.g. FIFO queues, priority queues) is insuucient. Alternative models are essential t...
