High-valued traders, or intra-marginal traders, can give a market higher transaction rates and generate more profit both for the traders and for the market maker. In previous CAT tournaments with competing market specialists, and in accordance with economic theory, markets using registration fee policies attract intra-marginal traders and drive out extra-marginal traders. We build a simple trad...

We study game theoretic decision making using a bidirectional evidence accumulation model. Our model represents both preferences for the strategies available to the decision maker, as well as beliefs regarding the opponent’s choices. Through sequential sampling and accumulation, the model is able to intelligently reason through two-player strategic games, while also generating specific violatio...

A four-period game is developed between a policy maker, the international community, and the population. This research supplements, through implementing strategic interaction, earlier research analyzing "one player at a time". The first two players distribute funds between preventing and treating diseases. The population reacts by degree of risky behavior which may cause no disease, disease con...

The effect of learning on climate policy is not straightforward when climate policy is concerned. It depends not only on the ways that climate feedbacks, preferences, and economic impacts are considered, but also on the ways that uncertainty and learning are introduced. Deep (or fat-tailed) uncertainty does matter for the optimal climate policy in that it requires more stringent efforts to redu...

Multiagent Partially Observable Markov Decision Processes are a popular model of multiagent systems with uncertainty. Since the computational cost for finding an optimal joint policy is prohibitive, a Joint Equilibrium-based Search for Policies with Nash Equilibrium (JESP-NE) is proposed that finds a locally optimal joint policy in which each policy is a best response to other policies; i.e., t...

the non-definite multi-attribute decision making problem is the further expansion of research to the traditional multi-attribute decision making problem. In the actual decision-making, because of policy-making question's complexity, decision-making information acquisition costs and other reasons, the decision information which the policy-maker can obtain are mostly ambiguous, so in the real lif...

When subjective descriptions of judgmental policies have been compared to statistical descriptions of policies, investigators have repeatedly found an imperfect correspondence between subjective and statistical measures of importance. There is reason to believe, however, that these findings may be due to the use of inadequate procedures for obtaining subjective weights. The present study, there...
