Neighbourhood effects and social behaviour: the case of irrigated and rainfed farmeres in Bohol, the Philippines

Artefactual field experiments, spatial econometrics, and household survey are blended in a single study to investigate how the experience of collective irrigation management in the real world facilitates the spillover of social behaviour among neighbours. The dictator and public goods games are conducted among irrigated and non-irrigated rice farmers in the Philippines. The spillover effect is found only among irrigated farmers. In the public goods game, punishment through social disapproval reduces free-riding more effectively among irrigated farmers. These indicate that strengthened ties among neighbours are likely to induce the spillover of social norms together with an effective punishment mechanism.
