The results of twenty-four laboratory sessions are evaluated with respect to the role of alternative definitions of equity when communication is introduced into an environment in which voluntary contributions determine the level of public good provision to small groups of individuals....

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...

Using eight sessions (twenty-four ten-period markets) in a double ABA cross-over design, we demonstrate clear evidence of market power in double-auction emission trading markets (agents who are not constrained to only buy or sell). Conventional theory predicts that in half of the market-power...

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...

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