Bias in discrete response contingent valuation

Article Abstract:

The bias inherent maximum likelihood estimation models is investigated. The bias arises from minimal changes in the statistical models and leads to substantial differences in the point estimates of willingness to pay when discrete response contingent valuation is employed. To this end, single-bounded and double-bounded maximum likelihood methods are evaluated for bias and their response to different bid designs and sample sizes.

Winners and losers in a world with global warming: noncooperation, altruism, and social welfare

Article Abstract:

A simple theoretical model was used to examine the win-lose scenario in a world with global warming. Several institutional arrangements were compared using measures of allocative efficiency and social welfare. The allocations proved to be efficient in the cases of full altruism and full decentralization. Moreover, the socially optimal allocation could only be implemented in the altruistic case as a noncooperative equilibrium.
