Two approaches to emissions trading are cap-and-trade, in which an aggregate cap on emissions is distributed in the form of permits, and baseline-and-credit, in which firms earn credits for emissions below their baselines. Theoretical considerations suggest the long-run equilibria of the two...

We study cheap-talk communication in common pool resource environments with and without output-sharing groups. Communication in groups of 12 does not improve efficiency over the non-cooperative Nash outcome without communication. Organizing subjects into output-sharing groups of four players...

This paper presents the results of a revealed-choice experiment testing the theoretical predictions of a model of a mixed system of public and private finance. In the context of a mixed system of health care finance, we investigate behavioural responses to changing the public sector allocation...

Two approaches to emmisions trading are cap-and-trade, in which an aggragate cap on emmisions is distributed in the form of permits, and baseline-and-credit, in which firms earn credits for emissions below their baselines. Theoretical considerations suggest the long-run equilibria of the two...

We test the null hypothesis that involuntary transfers for the provision of a public good will completely crowd out voluntary transfers against the warm-glow hypothesis that crowding-out will be incomplete because individuals care about giving. Our design differs from the related design used by...

This paper provides an experimental testing ground for an equal output-sharing partnership approach as a common pool resource (CPR) management instrument. It examines the behaviour of resource users in output-sharing partnerships of different sizes, and evaluates the impact of partnership size...

We investigate the effects of heterogeneity, incomplete information and communication on aggregate contributions to a public good using the voluntary contribution mechanism in a nonlinear laboratory environment. One-dimensional heterogeneity (heterogeneity in income or preferences) and...

Schott et al. (2007) have shown that the “tragedy of the commons” can be overcome when individuals share their output equally in groups of optimal size and there is no communication. In this paper we investigate the impact of introducing communication groups that may or may not be linked to...
