  This paper addresses mechanisms for boundedly rational decision makers in
discrete choice problem. First, we introduce two mathematical models of
population dynamics with conformity biases. We next analyze the models in terms
of delta-passivity, and show that the conformity biases work to break passivity
of decision makers. Based on the passivity perspective, we propose mechanisms
so as to induce decision makers to a desired population state. Furthermore, we
analyze a convergence property of designed mechanisms, and present parameter
conditions to guarantee stable inducements.
