Q&A communities have been developed. However, it is difficult to consider a design of the management systems effective for the community. We present an agent-based model, focusing on pecuniary payback, of a Q&A community, and we clarify the effective payback system policy for various community environments through simulation. Our results showed the following. In a system where pecuniary payback is low, there are many answers. In addition, in a system where pecuniary payback is high, quality of answers is high, and even if a questioner's question-effort is low (even if a questioner posts an ambiguous question), the community for which answers gather is formed.
