Abstract
The aim of this article is to suggest a research approach to be used in studies of common‐pool resource problems and the deterioration of reindeer pasture. A frequent strategy in such studies is game theory based on rational choice assumptions. This approach has been criticised, for instance, for the neglect of local knowledge concerning cultural preconditions and for the political implications damaging Saami reindeer‐ecology. Our contention is that such problems can be handled by combining game theory with participatory action research when studying the subject above.
