This paper uses laboratory experiments to examine the effect of an endogenous rule change from open access to private property as a potential solution to overharvesting in commons dilemmas. A novel, spatial, real-time renewable resource environment was used to investigate whether participants were willing to invest in changing the rules from an open access situation to a private property system. We found that half of the participants invested in creating private property arrangements. Groups who had experienced private property in the second round of the experiment, made different decisions in the Rachel Vilensky recruited the participants. Yajing Wang, Michael Schoon, Tun Myint, Elinor Ostrom, Pamela Jagger, and Frank van Laerhoven assisted Janssen in performing the experiments. Also, many graduate students, staff, and faculty pre-tested the experiments and we thank them for all of their help. Janssen did the data analysis with input from Takao Sasaki. We are appreciative of the excellent comments of two anonymous reviewers.
