Abstract
  • We empirically estimate the effects on management outcomes in common-pool resource management into three: the direct effect of management systems, the direct effect of social capital, and the indirect effect of management systems and social capital interacting each other to influence the outcomes. In particular, we focus on revenue sharing arrangement as a possible management tool in a fishery, in which a group of harvesters shares catch and/or revenue among the members of a fishery cooperative. In addition to each of revenue sharing and social capital influencing a fishery independently we hypothesize the synergy between revenue sharing and social capital. Social capital potentially affects the efficiency that revenue sharing brings while revenue sharing can foster social capital, which eventually leads to better management outcomes. An important intermediary between the two factors and the outcomes is collective efforts performed as a group often in a community-managed fishery. We quantified social capital using controlled economic experiments with fisherman subjects as well as surveys. Using the data collected from ten Japanese fishery groups and wild cluster bootstrap for small sample inference, we find evidence that revenue sharing and social capital interact to affect the fishery information network. However, we find no robust evidence of the direct effect of revenue sharing improving an outcome in a fishery. The results also show that fishery groups achieving economic success are comprised of fishers with higher general trusting attitudes and fishery groups achieving better stock conditions consists of fishers having similar information network size.
